Abstract:
Sperm acquires capacity of motility and fertility during the process of semen coagulation and liquefaction. The main coagulative protein is Semenogelin I (Sg I), specifically produced by seminal vesicles, and then decomposed by prostate specific antigens (PSA) in sperm liquefaction into a series of small fragments. These fragments, with a variety of physiological functions, are very important for the regulation of sperm capacity acquisition and progressive movement.
