Join our Male Fertility Research Program

The majority of current fertility testing focuses on women, putting the onus of fertility issues on their shoulders. Traditional tests for men that are used were developed more than 60 years ago. PS Fertility is changing that with testing that focuses on the male’s ability to fertilize an egg – not simply on sperm’s viability.

A groundbreaking discovery from researchers at the University of Virginia School of Medicine led to fresh insights on how sperm and eggs fuse. Two of the original researchers, Jeffrey Lysiak and Kodi Ravichandran, are co-founders of PS Fertility. They are continuing their work into the egg’s role in the fertilization process, which lays the groundwork for innovative fertility treatments.

The UVA research uncovered a molecular marker (phosphatidylserine or PS) on the surface of sperm that binds with a corresponding substance on the egg to facilitate fusion. Our new testing focuses on the presence of PS, an indicator of the competency of the sperm to promote fusion with the egg for viable fertilization.
