| Semen is produced by accessory glands of the male reproductive tract. Accessory glands are composed of seminal vesicles, prostate gland, and bulbourethral glands. The prostate gland produces elements such as zinc, citric acid, prostasome, and Prostate Specific Antigen (PSA) that play a role in sperm motility. Seminal vesicles secrete fructose, ascorbic acid, coagulation enzymes, and prostaglandins. Secretions from the seminal vesicles serve as an energy source, an antioxidant which indirectly contributes to the quality of sperm. The role of bulbourethral gland’s secrete on sperm quality has not been known clearly. |
