Do you trust that new medical diagnostic tests provide more reliable answers for fertility challenges?
PS Fertility has launched PS Detect, a diagnostic test designed to assess fertilization competence by measuring phosphatidylserine on the surface of sperm. The test provides a PS Score to help identify male fertility issues that standard semen analyses may miss.
Why it matters
Standard semen analysis frequently fails to identify male fertility issues in couples struggling to conceive, as nearly 30% of men with normal results still experience infertility. This new test aims to bridge that diagnostic gap by evaluating sperm-egg fusion capability.
Male factors contribute to approximately 50% of all infertility cases. Additionally, 20-30% of men who receive normal results from conventional semen analysis still struggle with fertility.
The players
PS Fertility
This biotechnology company is headquartered in Charlottesville, Virginia, and focuses on developing advanced diagnostic tools for male reproductive health.
The details
The test identifies phosphatidylserine levels on live sperm, generating a score that reflects the percentage of cells expressing the biomarker. Clinicians use these scores alongside traditional semen analysis to better understand fertilization competence, and data shows scores can improve after varicocele repair surgery.
Timeline
PS Fertility announced the product launch on October 14, 2026.
Health Landscape
This diagnostic tool represents a shift in reproductive medicine by moving beyond traditional physical sperm counts toward molecular analysis of functional fertilization capability. It signals an evolution in clinical standards as providers seek more precise metrics to explain unexplained male infertility.
Patients may now have access to a more granular assessment of their fertility status beyond standard screening tests. This diagnostic information could provide clearer insight into reproductive challenges and potentially inform treatment decisions like varicocele repair.
The takeaway
Advancements in biomarker testing offer a new way for couples to identify potential hurdles when traditional tests appear normal. Clinicians can use these scores to gain a more comprehensive understanding of male fertilization competence.
