It consists of fluids secreted from various glands. The seminal vesicles secrete about 70% of the semen. It consists of fructose. The prostrate gland secrete about 20% volume of the semen. The fluid consists of acid phosphatase, and proteolytic enzymes. The bulbourethral gland secretes about 5% of the total volume of semen. It consists of mucoproteins.
