YO® Smartphone Home Sperm Test Versus Manual Semen Analysis in Egyptian Men

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.

Evaluating the Utility of Implementing Microfluids for Sperm Preparation Compared to Conventional Method of Density Gradient Centrifugation in a PGT-A Program: a Sibling Oocyte Study

In assisted reproductive technology (ART), sperm preparation aims to select the most viable sperm for ICSI. Unlike conventional methods like density gradients or sperm washing, microfluidic techniques mimic natural selection in the female reproductive tract by using laminar flow without centrifugation, reducing the risk of DNA damage. This method isolates highly motile sperm while filtering out debris and immotile cells. Studies show that microfluidics improve embryo quality, increase pregnancy rates, and may lead to higher euploidy rates. Additional benefits include improved safety, scalability, and shorter preparation times.

Testicular Function and Semen Quality in Male Childhood and Adolescent Cancer Survivors

Cancer treatment can affect the testicular function, including sperm and hormonal functions. The aim of this study is to assess the testicular function and semen quality in young men who recover from childhood and adolescent cancer in Hong Kong. This can provide more information for pre-treatment counselling as well as improve post treatment survivorship care. The testicular function will be compared to aged-matched controls from men attending the Family Planning Association for premarital check-up.
