Semen Analysis

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.

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.
