-Summary

This study compares the YO® Home Sperm Test, a smartphone-based semen testing device, with conventional manual semen analysis performed according to the World Health Organization (WHO) 6th edition laboratory manual. Each participant provides one semen sample. A small aliquot is taken for testing with the YO® device, performed by the participant himself under supervision according to the manufacturer's instructions, and the remainder of the sample is analyzed manually in the andrology laboratory. The main question is how closely the motile sperm concentration (MSC) measured by the YO® device correlates with the MSC calculated from manual analysis. Secondary comparisons include sperm concentration, total motility, progressive motility and progressively motile sperm concentration. The study also compares the time needed to obtain results by each method and assesses participants' ease of use and satisfaction with the device. The aim is to determine whether this device could serve as a private, accessible screening tool for male fertility in Egypt.

+Detailed description

Male factor contributes to about half of all infertility cases, yet in Egypt many men delay or avoid semen analysis because of social stigma and discomfort with providing samples in a clinical setting. The YO® Home Sperm Test uses a smartphone camera and a miniature optical attachment to record a video of the semen sample and calculate sperm concentration, total motility, progressive motility, motile sperm concentration (MSC) and progressively motile sperm concentration (PMSC), reporting the MSC result as "Low" or "Moderate/Normal" using a threshold of approximately 6 million motile sperm/mL. Published validation studies compared the device mainly with automated semen analyzers; data comparing it with manual microscopic analysis, the routine method in Egyptian andrology laboratories, are limited.

This prospective comparative cross-sectional study is conducted at the Andrology Laboratory, Faculty of Medicine, Al-Azhar University, Cairo, Egypt. Each participant provides a single semen sample collected by masturbation after 3 to 5 days of sexual abstinence into a sterile wide-mouthed container. After complete liquefaction, the sample is processed as follows:

YO® test: a small aliquot of the sample, in the volume specified by the manufacturer's instructions, is taken for testing with the YO® Home Sperm Test. Each participant receives a demonstration and explanation, then performs the test himself in a separate room within the same facility, with assistance and under supervision of trained medical personnel.

Manual analysis: the remainder of the sample is analyzed manually according to the WHO Laboratory Manual for the Examination and Processing of Human Semen (6th edition), including sperm concentration, total motility and progressive motility. MSC is calculated as: total sperm concentration × percentage of motile sperm / 100, and PMSC as: total sperm concentration × percentage of progressively motile sperm / 100.

The primary comparison is MSC between the two methods. Secondary comparisons include sperm concentration, total motility, progressive motility and PMSC. Results are compared for correlation, agreement and time to result. Participants also complete a short questionnaire on perceived ease of use and satisfaction with the device for potential home use.

YO® Home Sperm Test and Manual Semen AnalysisExperimentalDevice: YO® Home Sperm Test; Diagnostic Test: Manual Semen Analysis (WHO 6th Edition)Adult men attending the Andrology Laboratory, Faculty of Medicine, Al-Azhar University, who provide a single semen sample. A small aliquot of each sample is tested with the YO® Home Sperm Test, performed by the participant himself after demonstration and under supervision according to the manufacturer's instructions. The remainder of the sample is analyzed manually according to the WHO 6th edition manual as the reference standard. Participants then complete a short questionnaire on ease of use and satisfaction with the device.
  • YO® Home Sperm Test (Device): FDA-cleared smartphone-based semen testing device that uses a miniature optical attachment and the smartphone camera to record a video of the semen sample and report sperm concentration, total motility, progressive motility, motile sperm concentration (MSC) and progressively motile sperm concentration. Performed by the participant after demonstration, under supervision of trained medical personnel.
  • Manual Semen Analysis (WHO 6th Edition) (Diagnostic test): Conventional microscopic semen analysis performed by trained laboratory personnel according to the WHO Laboratory Manual for the Examination and Processing of Human Semen (6th edition, 2021), including sperm concentration, total motility and progressive motility, with manual calculation of MSC and progressively motile sperm concentration.

+Outcome measures

Primary outcomes

  • Correlation Between YO® and Manual Motile Sperm Concentration (MSC) [Day 1 (single study visit, within 1 hour of semen sample collection)]: Correlation coefficient and agreement (Bland-Altman mean bias and 95% limits of agreement) between motile sperm concentration (million/mL) measured by the YO® Home Sperm Test and MSC calculated from manual semen analysis according to the WHO 6th edition manual.

Secondary outcomes

  • Diagnostic Agreement Between YO® and Manual Analysis in Classifying Oligozoospermia and Asthenozoospermia [Day 1 (single study visit, within 1 hour of semen sample collection)]: Sensitivity, specificity, positive and negative predictive values, overall accuracy and Cohen's kappa of the YO® Home Sperm Test in classifying samples as oligozoospermic (sperm concentration below 16 million/mL), asthenozoospermic (progressive motility below 30%) or oligoasthenozoospermic, using manual semen analysis according to the WHO 6th edition lower reference limits as the reference standard.
  • Agreement in Sperm Concentration Between YO® and Manual Analysis [Day 1 (single study visit, within 1 hour of semen sample collection)]: Correlation and agreement between sperm concentration (million/mL) measured by the YO® device and by manual semen analysis.
  • Agreement in Total Motility Between YO® and Manual Analysis [Day 1 (single study visit, within 1 hour of semen sample collection)]: Correlation and agreement between total sperm motility (%) measured by the YO® device and by manual semen analysis.
  • Agreement in Progressive Motility Between YO® and Manual Analysis [Day 1 (single study visit, within 1 hour of semen sample collection)]: Correlation and agreement between progressive sperm motility (%) measured by the YO® device and by manual semen analysis.
  • Agreement in Progressively Motile Sperm Concentration (PMSC) Between YO® and Manual Analysis [Day 1 (single study visit, within 1 hour of semen sample collection)]: Correlation and agreement between PMSC (million/mL) measured by the YO® device and PMSC calculated from manual semen analysis.
  • Time to Result [Day 1 (single study visit, within 1 hour of semen sample collection)]: Time in minutes from sample liquefaction to availability of the result, for the YO® device and for manual semen analysis.
  • Participant Ease of Use and Satisfaction With the YO® Device [Day 1 (single study visit, within 1 hour of semen sample collection)]: Participant-reported ease of use and satisfaction with the YO® Home Sperm Test for potential home use, assessed with a short questionnaire.
