Secretions
Prostatic secretions vary among species. They are generally composed of simple sugars and are often slightly acidic.
In human prostatic secretions, the protein content is less than 1% and includes proteolytic enzymes, prostatic acid phosphatase, beta-microseminoprotein, and prostate-specific antigen. The secretions also contain zinc with a concentration 500–1,000 times the concentration in blood.
