Main Article Content
Abstract
Prostate
specific antigen (PSA) is a serine protease enzyme which is produced by the columnar acinar and ductal prostatic epithelial cells. Its function is to liquefy the semen in seminal coagulum in order to allow the sperm to swim freely. It is also thought to be important in dissolving the cervical mucous cap, allowing the entry of sperm into the uterus. The half-life of PSA is approximately 2.2 days. The normal range of serum PSA in men varies with age. Serum PSA concentrations also vary physiologically, according to race and prostate volume.
