An Emerging Role of TEX101 Protein as a Male Infertility Biomarker.
Infertility is an important aspect of human reproduction. It affects up to 15% of couples, with the male factor contributing to approximately 50% of all cases. Azoospermia is one of the most severe forms of male infertility, which is characterized by the absence of sperm in semen. The mechanisms underlying male infertility remain unknown. Currently, clinicians rely on semen analysis to predict the reproductive potential of a male, and testicular biopsy is the only reliable method to diagnose different subtypes of azoospermia. Recently, advances in proteomics encouraged the search for novel male infertility biomarkers in seminal plasma. In this review, we focus on TEX101, a testicular germ cell-specific protein, one of the most promising male infertility biomarkers. We discuss its role in spermatogenesis and fertilization and summarize our current knowledge about this new potential biomarker.
