The predictive value of serum sex hormones for the outcome of testicular sperm aspiration in azoospermia [PDF]
Azoospermia is a condition that affects the reproductive health of approximately 1% of the male population, typically diagnosed through testicular biopsy. Noninvasive serum markers can play a significant role in the diagnosis of azoospermia diagnosis.

Participation of epididymal cysteine-rich secretory proteins in sperm egg fusion and their potential use for male fertility regulation [PDF]
Rat protein DE is an androgen-dependent cysteine-rich secretory protein (CRISP) synthesized by proximal epididymal regions. DE, also known as CRISP-1, is localized on the equatorial segment of acrosome-reacted spermatozoa and participates in gamete ...
