Prostatic secretions are thin, milky, and alkaline. The secretions are made up of many different components. Citrate, a major component of prostatic fluid, provides a good transport medium for spermatozoa by maintaining the osmotic equilibrium of the seminal fluid. Prostatic secretions have high levels of prostatic acid phosphatase (PAP) and prostate-specific antigen (PSA). Semen contains high levels of zinc, which is derived from the prostate. Zinc has antibacterial properties.
