Free Nurse obtaining sperm sample video PORN Videos Manual microscope-based testing and computer-assisted semen analysis CASA are the current standard methods to diagnose male infertility; however, these methods are labor-intensive, expensive, and laboratory-based. Cultural and socially dominated stigma against male infertility testing hinders a large number of men from getting tested for infertility, especially in go here African countries. We describe the development and clinical testing of an Nurse obtaining sperm sample video smartphone-based semen analyzer designed for quantitative measurement of sperm concentration and motility for point-of-care male infertility screening. The work suggests that the integration of microfluidics, optical sensing accessories, and advances in consumer electronics, particularly Nurse obtaining sperm sample video capabilities, can make remote semen quality testing accessible to people in both developed and developing countries who have access to smartphones. Sperm abnormalities are definitive markers for male infertility and have been linked to varicocele, hormonal imbalances, and genetic reasons such as Y-deletions 2 — 4but other Nurse obtaining sperm sample video conditions can also influence semen quality 5. Sperm abnormalities may be correlated with lifestyle and environmental effects as well 6. Semen analysis is considered gives footjob Redhead cornerstone in male infertility evaluation, but men often feel embarrassed to go to urologists, and women carry the weight with regard to infertility most of the time 78. Furthermore, health care disparities related to economic, cultural, societal, geographical, and religious factors are major impediments to accessing infertility care worldwide, especially in developing countries, making it one of the most underestimated and neglected health care issues 9. Here, we present a true point-of-care smartphone-based semen Nurse obtaining sperm sample video that is easy to use, rapid, automated, and inexpensive. It provides sperm concentration, motility, and Nurse obtaining sperm sample video and curvilinear velocities by performing an on-phone image analysis using a semen sample loaded into a low-cost disposable microfluidic device. Along with a modular wireless weight scale, it also provides semen volume, total sperm count, and total motile sperm count. Watch XXX Videos Rack power strip box.

Numerous health care applications have stemmed from supplementing external attachments to smartphones 23 — 25 , with multiple point-of-care diagnostic devices using the on-board smartphone camera 25 — Integrating microfluidics, optical sensing modality, and smartphones can provide a powerful platform to develop affordable and easily accessible point-of-care fertility diagnostic assays. We have evaluated the assay using fresh, unwashed, unprocessed patient semen samples by comparing the results obtained by the smartphone-based assay performed by trained and untrained users with the results obtained by a CASA-based platform. The quantitative results on patient semen samples showed an excellent agreement between the smartphone-based platform and CASA using Passing-Bablok regression analysis and Bland-Altman analysis. A i Process of operation: A small volume of an unwashed, unprocessed semen sample is loaded into a microfluidic device that has a capillary-based disposable tip at the inlet and a rubber bulb at the outlet to create negative pressure in the microchannel for manual, power-free sample loading. The user manually detaches the capillary disposable tip from the microfluidic device through a simple snap-off mechanism and inserts the clean microfluidic device into the smartphone optical attachment. The sample is drawn using a pipette and is loaded onto a semen glass slide counting chamber. The glass slide is placed under a desktop microscope, and a technician performs the analysis either manually or using a CASA system. B Actual image of the smartphone accessory and the microchip C along with its side view. The hardware component of the smartphone-based platform consists of an optical attachment for image magnification and device positioning and a disposable microfluidic device for semen sample handling. The optical attachment was custom-designed to align its optical axis to the smartphone camera through a simple slide-on mechanism. The optical attachment was designed to have an opening to pass the microchip through for chip positioning on the attachment. The need for manual focusing was eliminated by positioning the microchip slot at a specific distance from the lens arrangement such that the sample contained in the microchip is in optimal focus. The device was calibrated using a micrometer scale fig. S2 and movie S1. The disposable microfluidic device for semen sample handling was designed on the basis of a power-free mechanical pumping mechanism using a polydimethylsiloxane PDMS bulb for easy-to-use, on-chip semen sample loading through creating a negative pressure chamber at the end of the device fig. S3 and Fig. The software smartphone application of the technology was designed with a user-friendly interface to guide the user through each step of testing fig. The test results are stored locally on the phone for semen quality monitoring over time. The smartphone application was able to image, automatically analyze, and report the results at an average time of 4. A separate technician performed a parallel microscope-based manual sperm count using a standard hemocytometer. This evaluation showed the ability of the assay to be used for monitoring patients who undergo vasectomy. In Fig. These statistical analyses showed that the difference between manual and smartphone-based semen analyses increased as sperm concentration increased in the semen samples. However, we did not observe a fixed difference in measuring sperm concentration between the two methods. To establish a threshold for optimum sensitivity and specificity, we performed receiver operating characteristic ROC analysis. ROC analysis plot along with a vertical scatterplot illustrated the sensitivity and specificity of the device Fig. The accuracy was A Direct comparison of sperm concentrations calculated by the smartphone-based device and manual microscope-based method. B Bland-Altman analysis to compare the results obtained by the smartphone-based semen analyzer and manual microscope-based method. Manual analysis was used as the reference method. To evaluate the performance, sensitivity, specificity, and accuracy of the smartphone-based semen analyzer, we tested semen samples from patients at the Massachusetts General Hospital MGH fertility clinic and compared the results with the results obtained by a CASA-based platform for semen analysis table S4. The A and B values were 1. We also performed Passing-Bablok analysis on sperm motility measurements for patient semen samples obtained using the smartphone-based semen analyzer and CASA Fig. Passing-Bablok analysis to compare A sperm concentration and B sperm motility as measured by the smartphone-based semen analyzer and CASA for all patient semen samples.

Collectively, Passing-Bablok and Bland-Altman analyses showed that the difference between CASA and the smartphone-based device in measuring sperm concentration and motility increased as sperm concentration and motility increased in the samples. These differences, however, did not have a significant effect on the ability of the smartphone-based semen analyzer to identify abnormal semen samples. The sensitivity and specificity of the smartphone-based device to detect abnormal semen samples based on sperm concentration criterion were The observed AUC was 0. The sensitivity and specificity of the device based on sperm motility criterion were These results showed that the sensitivity and specificity of the smartphone-based semen analyzer to detect abnormal semen samples using both sperm concentration and motility parameters were The smartphone-based semen analyzer was able to rapidly and accurately calculate the average linear and curvilinear velocities of sperm in an undiluted, unwashed semen sample. S6 and table S4. These results suggest high comparability of the smartphone-based device with CASA for sperm velocity measurement. The smartphone-based semen analyzer also has the potential to measure total sperm count and total motile sperm count based on the WHO guidelines We developed a separate compact custom-designed modular wireless weight scale for semen sample volume estimation fig. The performance of the weight scale module was first evaluated by comparing its results with the results obtained by a conventional weighing scale Ohaus, EP64 Explorer Pro. The current version of the smartphone-based semen analyzer uses the smartphone camera for sample imaging and can be used with different cellphones with minor modifications in the hardware optical attachment depending on the physical dimensions of the cellphone. S9 and table S8. No changes were made to manually tune the optical focus. S9B was performed for 13 unprocessed semen samples. The mean bias between Moto X and Moto G4 smartphones was 0. We also performed Bland-Altman analysis for sperm motility measurements for the 13 semen samples using i Moto X and Moto G4 smartphones fig. These results showed that there was no difference between the three smartphones in identifying undiluted, unwashed abnormal semen samples based on the WHO criteria on sperm concentration and motility. Minor differences were observed in terms of quantitative measurements. To evaluate the usability and simplicity of the smartphone-based male infertility screening device, we recruited untrained users and performed a double-blinded evaluation of semen analysis using the smartphone-based platform and CASA Fig. None of the developers of the smartphone-based semen analyzer were present during the double-blinded usability experiments. Scatterplots E and F represent the qualitative performance of the device in measuring concentration and motility. These results showed that the difference between CASA and smartphone-based device in measuring sperm concentration increased with an increase in sperm concentration of the semen samples. Figure 4B shows a Passing-Bablok analysis of sperm motility measurements for patient semen samples obtained using the smartphone-based device and CASA. The A and B values were 0. There was an increase in the difference between CASA and the smartphone-based system in measuring sperm motility with an increase in the motility of the semen samples. We did not observe a fixed difference between CASA and the smartphone-based system in measuring sperm concentration and motility of the semen samples. It is then extruded from its sheath, and the collector massages the dog's erect penis near the base of the bulbus glandis using the thumb and index finger. The dog begins pelvic thrusting movements at the onset of ejaculation. Semen can be collected from wolves via manual stimulation [24] or electroejaculation. From Wikipedia, the free encyclopedia.

Then I noticed a fridge in the corner that contained airliner serves of cheese and biscuits and juices for refreshment. Then I sat on the couch and watched porn while I ate. There were tissues, lube, rubber gloves, and a type of disposable blanket to spread over the couch.

The conditions can be less than ideal: With sperm, timing is of the essence, so plan accordingly. This means no sex or no ejaculation of any kind, including masturbation. Longer or shorter periods of abstinence may result in a lower sperm count or decreased sperm motility. Samples produced after two days of abstinence will usually have the highest numbers of motile sperm with the greatest forward velocity, when compared to samples produced after shorter or longer abstinence. Older sperm begin to die if ejaculations are infrequent and the percentage of live sperm decreases with increasing abstinence. Clean up your act..

Device variability, coefficient of variation CVin preclinical samples was 4. The optical attachment and the smartphone application were designed such that minimal input from an untrained user was required.

The optical focus and lighting intensity were optimized and fixed in the smartphone accessory to eliminate the need for manual adjustment by the user and to reduce the errors in image processing. Professional training and routine click here control exercises are critical to minimize errors in CASA-based and manual microscope-based semen analysis methods. Our easy-to-use platform eliminates the need for such exercises and may aid in the standardization of semen tests because variability in semen analysis is still relatively Nurse obtaining sperm sample video Furthermore, infertility in resource-limited settings is also a global issue, and the ability to provide routine, point-of-care, low-cost, reliable semen analysis testing is needed 9.

CASA systems are relatively expensive, and even in the United States, many clinics and fertility centers use manual semen analysis methods, resulting in poor standardization 10 The smartphone-based semen analyzer may also be used for home-based monitoring of men who undergo vasectomy. It is estimated that worldwide more than 33 million couples prefer to perform vasectomy as a safer, less expensive, and simpler method compared to female sterilization for contraception There Nurse obtaining sperm sample video more than 20 million men who underwent vasectomy in China and India alone The number of vasectomy procedures per year in the United States has been estimated to be betweenandprocedures per year 35 It has been reported that patient compliance for postvasectomy follow-up semen analysis has been extremely poor The smartphone-based semen analyzer has Nurse obtaining sperm sample video potential to Nurse obtaining sperm sample video patient compliance for postvasectomy semen analysis by providing a rapid, easy-to-use, Nurse obtaining sperm sample video, and private method for accurate sperm concentration and motility measurement.

Nurse obtaining sperm sample video

One of the limitations of automated optical-based semen analyzers is measuring sperm concentration with high accuracy in samples Nurse obtaining sperm sample video higher-than-average numbers of nonsperm cells such as white blood cells. We have designed our sperm detection and tracking algorithm to perform size-based differentiation of sperm heads from other larger cells such as white blood cells.

However, although our single parameter—based detection algorithm is effective at reducing processing time, it is prone to misidentifications when nonsperm cells or debris of similar size to the sperm head are present in the FOV of the smartphone-based semen analyzer. This limitation may be overcome with a more computationally intensive set of image processing algorithms at the expense of processing time or with relatively more expensive optical sensing—based hardware.

Similarly, our current version of the smartphone-based semen analyzer cannot evaluate sperm morphology; however, its ability to accurately identify abnormal semen samples based on sperm concentration and motility can potentially shift the paradigm in male infertility management in both Nurse obtaining sperm sample video and developing countries.

A rapid, point-of-care diagnostic assay for semen analysis can also have an important application in animal breeding.

Currently, animal breeders immediately transfer collected semen samples to an equipped laboratory for semen analysis through a sample transfer process with a controlled exposure to environmental effects such as cold, excessive heat, light, shock, and physical trauma. Therefore, a regular point-of-care semen analysis could have an important role in the efficient and cost-effective management of animal breeding.

Considering the differences between human semen and animal semen in terms of sperm concentration, motility, and Nurse obtaining sperm sample video volume, the current version of the smartphone-based semen analyzer would need to be augmented for applications in animal breeding. We envision that animal semen sample dilution would be required before semen analysis testing using the current version of the smartphone-based platform.

The advances in microtechnologies and the surge in consumer electronics have paved a solid foundation for developing mobile health mhealth technologies with the potential to transform the current paradigm in global health. The work reported here is an example of how smartphones can be seamlessly integrated with hardware, software, and microfluidics to develop a point-of-care diagnostic device to address clinical gaps in male infertility management.

The goal of this study was to develop and evaluate a smartphone-based diagnostic assay for point-of-care semen analysis through accurate sperm concentration and motility measurement using a small undiluted, unprocessed semen sample loaded into a disposable microchip. We read more increased the number of Nurse obtaining sperm sample video to more than to achieve greater clinical relevance with more statistical power.

This sample size Nurse obtaining sperm sample video increased to to collect data from patient samples with a broad range of sperm concentrations and motilities below and above the WHO criteria.

Three repeated measurements were made for each sample to measure the coefficient of variability. Five Nurse obtaining sperm sample video semen samples were excluded from this study because of microfluidic device contamination by debris in the channels, which caused false detection. Precautionary methods were in place when continue reading were fabricated for the clinical assessment by taking steps to fabricate these devices in a sterile environment.

For the assessment of infertility diagnosis based on sperm concentration and motility, we carried out our evaluation using undiluted, unprocessed, fresh semen samples received from patients at the MGH fertility clinic, and the smartphone-based results were compared with the results calculated by a CASA-based platform Hamilton Thorne, HTM-CEROS II. Ten untrained users who were completely unfamiliar with Nurse obtaining sperm sample video smartphone-based semen analyzer were recruited to perform semen analysis tests with unwashed, undiluted semen samples.

The untrained users ranged from administrative staff with no background in science to clinical nurses. The users were between 25 and 45 years old. The results obtained by the untrained users were compared with the results obtained by CASA. An Nurse obtaining sperm sample video sheet was provided to the users, and the entire set of experiments was carried out in a double-blinded manner.

The original developers of the Nurse obtaining sperm sample video were not present during the device usability testing with the untrained users. No patient selection criteria were in place for the trained user study. No samples were excluded from this clinical evaluation study. During this study, we have also evaluated the performance of a modular weight scale attachment in estimating the total sperm count and total Nurse obtaining sperm sample video sperm count.

The rubber bulb used in the microfluidic devices for electric-free on-chip sample loading was made out of PDMS on a 3D printed master mold composed of acrylonitrile butadiene styrene Ultimaker. An extender cap, holding a plastic microhematocrit capillary tube Fisherbrand, as an extender capillary tip, was 3D printed with PLA.

The extender cap was placed at the inlet of the microfluidic device. Once the microchip containing Nurse obtaining sperm sample video sample is loaded into the attachment, the smartphone application records 1-s duration videos 30 fps and processes each frame to obtain the various semen parameters.

The image processing, sperm detection and tracking, and data analysis were all performed on-phone, which was running on Android 6. A custom Android Nurse obtaining sperm sample video was developed using Android Studio.

We used the sdk and ndk libraries provided with the Android development tools as well as other libraries including OpenCV version 2. The application was designed to process data obtained by the smartphone camera using the optical attachment. The analysis was performed in two steps: What are the best ways to increase sperm count?

Redtube femdom Watch Porn Videos Slowmotion Cumchots. Specimens analyzed were from patients seeking treatment from the Vincent Andrology laboratory at the MGH. Semen samples were obtained on-site by masturbation and collected into a sterile plastic container. This study was performed with compliance to previously published guidelines 31 , Men were instructed to abstain from ejaculation for at least 48 hours before the sample was produced. Semen sample volume was calculated by measuring the sample weight using a standard laboratory-based weight scale. A minimum of sperm cells from at least four different FOVs were analyzed from each specimen. Patient specimens were loaded into the microchip and tested using the smartphone-based semen analyzer in parallel to the CASA system. Single measurements were made for each sample tested with the smartphone-based setup regardless of the concentration. The participants were only given the device, disposables, and a simple instruction fig. S11 to perform the tests. The developers of the smartphone-based semen analyzer were not present at the site during the double-blinded semen analysis tests by untrained users. To evaluate the reliability of our CASA system for measuring sperm concentration, we tested and analyzed semen samples using both CASA and manual analysis before the initiation of the study. Similarly, we tested samples to evaluate the accuracy of the CASA system for motility measurement in comparison to manual analysis. Bland-Altman analysis 30 was performed using GraphPad Prism version 6. Sample size estimation was performed using MedCalc. Stata 13 was also used to calculate the classification accuracy reported for sensitivity and specificity of the device. Mean error was calculated by assigning weights for each of the classifications as obtained by both trained and untrained user groups. If the device classified the tested samples correctly relative to the CASA-based method, a score of 0 was assigned. Scores of 1 and 2 were assigned for false positives and false negatives, respectively. Arithmetic mean scores were obtained for sperm concentration, sperm motility, and overall results for both trained users and untrained users. We would like to thank J. Chavarro, M. Kathrins, R.

Ejaculate directly into the sterile sample cup. Try to capture the first part of the ejaculate and do not attempt to collect any spilled semen. Cap the container as soon as you have finished. Make sure your name and the time and date of your sample is clearly printed on the cup. Transporting Your Semen If you collected your sample in a place other than your clinic, you need to get it to the laboratory within one hour after ejaculation because sperm do not have a long life outside of the body and at different temperatures. In some cases, a person can collect the semen sample at home. A doctor can provide a special condom that allows a person to collect a semen sample during sexual activity. Otherwise, a doctor may recommend that the person ejaculates into a collection cup while at home. When collecting a sample at home, people must remember to keep it at room temperature and bring it to the laboratory within a short timescale after collection. The American Association for Clinical Chemistry recommends that medical professionals carry out 2 or more separate sperm analyses within 2- to 3-week intervals. As sperm profiles can vary from day-to-day, an average of these results may give the most accurate picture of sperm health. A sperm analysis looks at several factors when considering the health of the sperm. We discuss these factors and their results below. Sperm count refers to the number of sperm that are present in 1 ml of semen. World Health Organization WHO guidelines suggest that a normal sperm count is at least 15 million per ml or no fewer than 39 million sperm per sample. Having less than this indicates a low sperm count. Some research suggests that up to 90 percent of male infertility issues result from abnormal sperm counts. Home sperm analysis kits usually only test for sperm count. As this is just one aspect of male fertility, it is important that people see their doctor and get comprehensive sperm analysis to check for other factors affecting their sperm. Sperm motility is the ability of the sperm to move efficiently. Low motility can reduce the sperm's capacity to move through the female reproductive system to fertilize the egg. In a typical sample, at least 50 percent of the sperm will demonstrate normal motility. Morphology refers to the size and the shape of the individual sperm. Normal sperm have a long tail and oval-shaped head. Abnormally sized or shaped sperm can have difficulty reaching, penetrating, and fertilizing the egg. Normal semen contains a minimum of 4 percent sperm with standard form. Although sperm count, motility, and morphology are three of the main factors that medical professionals will check when assessing male fertility, they are not the only factors. The Centers for Disease Control and Prevention CDC advise that a slightly abnormal sperm analysis does not mean that a person is permanently infertile..

People may require a sperm analysis for different reasons. Some individuals or couples will request a sperm analysis if they are having difficulty conceiving. In couples that have been unable to conceive, some estimates suggest that there is a male factor present in 40 to 50 percent of cases. Up to 2 percent of men demonstrate issues with their sperm, resulting from one or a combination of:. People may also have a sperm analysis to check if a vasectomy was successful.

A vasectomy is a surgical procedure Nurse obtaining sperm sample video doctors carry out for permanent male sterilization. Following a vasectomy, doctors typically recommend regular sperm analyses for several months to ensure there are no sperm remaining in the semen. The most common way to collect a sample Nurse obtaining sperm sample video for a person to masturbate and ejaculate into a sterile Nurse obtaining sperm sample video. The doctor provides a private room for a person to do this.

In some cases, a person can collect the semen sample at home. A doctor can provide a special condom that allows a person to collect a semen sample during sexual activity. Otherwise, a doctor may recommend that the person ejaculates into a collection cup while at home.

Semen collection

When collecting a sample at home, people must remember to keep it at room temperature and bring it to the laboratory within a short timescale after collection. The American Association for Clinical Chemistry recommends that medical professionals carry out 2 or more separate sperm analyses within 2- to 3-week intervals. As sperm profiles can vary from day-to-day, an average of these results may give the most accurate picture of sperm health. A sperm analysis looks at several factors when considering the health of the sperm.

We discuss these factors and their results below. Sperm count refers to the number of sperm that are present in 1 ml of Nurse obtaining sperm sample video. World Health Organization WHO guidelines suggest Nurse obtaining sperm sample video a normal sperm count is at least 15 million per ml or no fewer than 39 million sperm per sample.

Collecting a Semen Sample

Having less than this indicates a low sperm count. Some research suggests that up to 90 percent of male infertility issues result from abnormal sperm counts. Home sperm analysis kits usually only test for sperm count. As this is just Nurse obtaining sperm sample video aspect of male fertility, it is important that people see their doctor and get comprehensive sperm analysis to check for other factors affecting their sperm.

Sperm motility is the ability of the sperm to move efficiently. Low motility can reduce the sperm's capacity to move through the female reproductive system to fertilize the egg. In a typical sample, at least 50 percent of the sperm will demonstrate normal motility.

Morphology refers to the size and the shape of the individual sperm. Normal sperm have a long tail and oval-shaped head. Abnormally sized or shaped sperm can have difficulty reaching, penetrating, and fertilizing the egg. Normal semen contains a minimum of 4 percent sperm with standard form.

Although sperm count, motility, and morphology are three of the main factors that medical professionals will check when assessing male fertility, they are not the only factors. The Centers for Disease Control and Prevention CDC advise that a slightly abnormal sperm analysis does not mean that a Nurse obtaining sperm sample video is Nurse obtaining sperm sample video infertile. Instead, doctors can use the results as a Nurse obtaining sperm sample video to help identify what factors are causing fertility issues.

People who receive abnormal results from a semen Nurse obtaining sperm sample video typically undergo further testing to help identify the exact issue. In many cases, a person's fertility issues resolve with the Nurse obtaining sperm sample video treatment. If the semen sample does not contain any sperm, people may be able to stop using condoms and other forms of birth controlas pregnancy is unlikely. However, if sperm is still present, people should continue using contraceptives to prevent unwanted pregnancies.

They may need further sperm analysis tests until their semen no longer shows the presence of sperm. A sperm analysis is one of the first tests that males undergo to look for the reasons for difficulty with conceiving.

People also Contorionist squirt own face pussy juice sperm analysis to check the success of a vasectomy. If sperm analysis results are abnormal, a doctor will typically recommend further testing to help find the underlying cause and formulate a treatment plan. Many cases of male infertility are treatable with lifestyle changes, medications, surgery, and other interventions.

If these are unsuccessful, a doctor or fertility counselor can help people explore other options, such as donor sperm or adoption.

Xxxvideos 3gp Watch Sex Videos Priankaxxx Sex. Furthermore, health care disparities related to economic, cultural, societal, geographical, and religious factors are major impediments to accessing infertility care worldwide, especially in developing countries, making it one of the most underestimated and neglected health care issues 9. Here, we present a true point-of-care smartphone-based semen analyzer that is easy to use, rapid, automated, and inexpensive. It provides sperm concentration, motility, and linear and curvilinear velocities by performing an on-phone image analysis using a semen sample loaded into a low-cost disposable microfluidic device. Along with a modular wireless weight scale, it also provides semen volume, total sperm count, and total motile sperm count. The critical components for determining seminal quality are sperm concentration, motility, and morphology. Manual microscope-based testing and computer-assisted semen analysis CASA systems are the current clinical standard methods; however, these methods are labor-intensive, expensive, and laboratory-based. CASA-based techniques require highly trained technicians for producing reliable and repeatable results. CASA techniques also require bulky microscope-based image analysis systems that greatly limit their point-of-care applications. Many fertility clinics and small hospitals are believed to not have CASA-based platforms and so use a time-consuming manual method for semen analysis Manual test results are subjective, therefore making it difficult to compare results from different clinics Turbidimetry 12 , photon correlation spectroscopy 13 , laser Doppler velocimetry 14 , impedance-based analysis 15 , lensless imaging 16 , paper-based colorimetric detection 17 , and ball lens—based imaging 18 are some of the other methods developed for semen analysis. However, these methods have not completely addressed all of the requirements for a true point-of-care, inexpensive, rapid, easy-to-use, automated diagnostic assay for semen analysis that can be used by an inexperienced user. Some of these methods cannot provide direct estimates of sperm concentration and motility, and almost all of the methods require expensive, bulky components for data collection and separate computational units for analysis of the collected data. Paper-based quantification assays may offer low-cost alternatives for routine semen analysis. One study made use of the color change resulting from the reactivity of yellow tetrazolium dye in the presence of the diaphorase flavoprotein enzyme present in human sperm to form purple formazan for the quantification of live and motile sperm concentrations Although the paper-based colorimetric analysis does not require expensive and bulky components, it requires a desktop scanner connected to a computer for measuring live and motile sperm concentrations with a limit of detection of 8. Similarly, although lensless imaging techniques benefit from large field-of-view FOV imaging, they are limited by the requirement of a separate computational unit for relatively time-consuming and computationally intensive hologram-based image reconstruction. The evaluation results demonstrated by the lensless imaging for semen analysis showed that accurate quantification of sperm concentration using this method is limited to 8. More recent work on point-of-care semen analysis using a ball lens—cellphone setup only magnifies the image of a semen sample pipetted onto polyethylene sheets that needs to be transferred to a separate monitor for manual analysis An expert technician can then manually count the number of sperm per FOV and evaluate the motility of the sample. The reported sperm motility results using this ball lens—cellphone setup suggest that this system may be susceptible to a high frequency of false negatives. Therefore, this ball lens—cellphone setup is not appropriate for home-based semen analysis. Current home-based male infertility assays on the market are FertilMARQ and SpermCheck, which use a chemical staining approach for detecting sperm-specific proteins on the sperm head. Trak, another U. Food and Drug Administration—approved product, uses centrifugal force to estimate sperm concentration on a microfluidic device However, all of these assays can only measure sperm concentration and not motility. Microfluidics as an enabling biotechnology has shown great promise in the development of biomedical devices with broad applications in medicine and biology, such as low-cost biosensing assays, single-cell analysis, gene expression profiling, and DNA sequencing The application of microfluidics for sperm analysis has garnered considerable attention over the past decade, and several advanced platforms have been developed, such as high-throughput sperm genomics On the other hand, advances in consumer electronics and particularly in mobile processing power, memory size, power consumption, and functionality have paved the way for their applications in health care Numerous health care applications have stemmed from supplementing external attachments to smartphones 23 — 25 , with multiple point-of-care diagnostic devices using the on-board smartphone camera 25 — Integrating microfluidics, optical sensing modality, and smartphones can provide a powerful platform to develop affordable and easily accessible point-of-care fertility diagnostic assays. We have evaluated the assay using fresh, unwashed, unprocessed patient semen samples by comparing the results obtained by the smartphone-based assay performed by trained and untrained users with the results obtained by a CASA-based platform. The quantitative results on patient semen samples showed an excellent agreement between the smartphone-based platform and CASA using Passing-Bablok regression analysis and Bland-Altman analysis. A i Process of operation: A small volume of an unwashed, unprocessed semen sample is loaded into a microfluidic device that has a capillary-based disposable tip at the inlet and a rubber bulb at the outlet to create negative pressure in the microchannel for manual, power-free sample loading. The user manually detaches the capillary disposable tip from the microfluidic device through a simple snap-off mechanism and inserts the clean microfluidic device into the smartphone optical attachment. The sample is drawn using a pipette and is loaded onto a semen glass slide counting chamber. The glass slide is placed under a desktop microscope, and a technician performs the analysis either manually or using a CASA system. B Actual image of the smartphone accessory and the microchip C along with its side view. The hardware component of the smartphone-based platform consists of an optical attachment for image magnification and device positioning and a disposable microfluidic device for semen sample handling. The optical attachment was custom-designed to align its optical axis to the smartphone camera through a simple slide-on mechanism. The optical attachment was designed to have an opening to pass the microchip through for chip positioning on the attachment. The need for manual focusing was eliminated by positioning the microchip slot at a specific distance from the lens arrangement such that the sample contained in the microchip is in optimal focus. The device was calibrated using a micrometer scale fig. S2 and movie S1. The disposable microfluidic device for semen sample handling was designed on the basis of a power-free mechanical pumping mechanism using a polydimethylsiloxane PDMS bulb for easy-to-use, on-chip semen sample loading through creating a negative pressure chamber at the end of the device fig. S3 and Fig. The software smartphone application of the technology was designed with a user-friendly interface to guide the user through each step of testing fig. The test results are stored locally on the phone for semen quality monitoring over time. The smartphone application was able to image, automatically analyze, and report the results at an average time of 4. A separate technician performed a parallel microscope-based manual sperm count using a standard hemocytometer. This evaluation showed the ability of the assay to be used for monitoring patients who undergo vasectomy. In Fig. These statistical analyses showed that the difference between manual and smartphone-based semen analyses increased as sperm concentration increased in the semen samples. However, we did not observe a fixed difference in measuring sperm concentration between the two methods.

We had a single in here recently, and she wanted someone from the west of Africa. So how do I provide my sample? Specific things that could affect the quality of your sperm sample include:. If you have severe male infertility, resulting in few or no sperm in the ejaculate, you may require a surgical procedure such as microsurgical epididymal sperm aspiration MESA or testicular sperm aspiration TESA. Most doctors recommend you ejaculate directly into a provided sample cup and not use a condom. If you must use a condom, your lab will provide a special semen collection condom. If you collected your sample in a place other than your clinic, you need to get it to the laboratory within one hour after ejaculation because sperm do not have a long life outside of the body and at different temperatures. Delays in delivering semen and exposure to various temperatures will results in lower overall motile sperm count and poor semen cryopreservation. Your semen sample should be kept as close to body temperature as possible. The sperm motility value will be inaccurately low if the semen sample gets cold and or if it gets too hot. Keep your specimen container upright in a plastic bag, with the lid securely tightened. People may also have a sperm analysis to check if a vasectomy was successful. A vasectomy is a surgical procedure that doctors carry out for permanent male sterilization. Following a vasectomy, doctors typically recommend regular sperm analyses for several months to ensure there are no sperm remaining in the semen. The most common way to collect a sample is for a person to masturbate and ejaculate into a sterile cup. The doctor provides a private room for a person to do this. In some cases, a person can collect the semen sample at home. A doctor can provide a special condom that allows a person to collect a semen sample during sexual activity. Otherwise, a doctor may recommend that the person ejaculates into a collection cup while at home. When collecting a sample at home, people must remember to keep it at room temperature and bring it to the laboratory within a short timescale after collection. The American Association for Clinical Chemistry recommends that medical professionals carry out 2 or more separate sperm analyses within 2- to 3-week intervals. As sperm profiles can vary from day-to-day, an average of these results may give the most accurate picture of sperm health. A sperm analysis looks at several factors when considering the health of the sperm. We discuss these factors and their results below. Sperm count refers to the number of sperm that are present in 1 ml of semen. World Health Organization WHO guidelines suggest that a normal sperm count is at least 15 million per ml or no fewer than 39 million sperm per sample. Having less than this indicates a low sperm count. Some research suggests that up to 90 percent of male infertility issues result from abnormal sperm counts. Home sperm analysis kits usually only test for sperm count. As this is just one aspect of male fertility, it is important that people see their doctor and get comprehensive sperm analysis to check for other factors affecting their sperm. Sperm motility is the ability of the sperm to move efficiently. Low motility can reduce the sperm's capacity to move through the female reproductive system to fertilize the egg. In a typical sample, at least 50 percent of the sperm will demonstrate normal motility. Morphology refers to the size and the shape of the individual sperm..
