Low‐Level Human Epididymis Protein 4 in Seminal Plasma Is an Independent Risk Factor for Poor Semen Liquefaction: A Case Control Study

Journal of Clinical Laboratory Analysis, Volume 40, Issue 18, September 2026.
Our work identifies a novel and significant association between low seminal levels of Human Epididymis Protein 4 (HE4) and the clinical condition of poor semen liquefaction, a common cause of male infertility. The findings are statistically robust, clinically relevant, and provide a foundational basis for future research into the mechanism by which HE4
