Historical Perspective

PSA is an endogenous serine protease and a member of the human kallikrein gene family identified in 1970. It is a 33kd protein produced and secreted primarily by the prostatic epithelium and epithelial lining of the periurethral gland. When secreted during ejaculation, PSA liquefies the seminal coagulum.
