Study Notes
Male Reproductive System
- Testes contain seminiferous tubules, which function as sperm-forming factories, producing 350-500 million sperm daily.
- Interstitial cells in the testes produce testosterone.
- Sperm travels to the epididymis, a comma-shaped, tightly coiled tube, where it matures and is stored for at least 20 days.
- Muscles in the epididymis walls contract to expel sperm into the vas deferens.
Vas Deferens and Ejaculatory Duct
- The vas deferens carries sperm from the epididymis to the ejaculatory duct.
- Vasectomy is a surgical procedure that involves cutting the vas deferens to prevent sperm transportation.
Urethra and Ejaculation
- The urethra extends from the urinary bladder to the tip of the penis, carrying both urine and sperm.
- Sperm enters the urethra from the ejaculatory duct.
- The prostate gland secretes a milky fluid that helps activate sperm.
- Seminal vesicles produce a thick secretion containing fructose, vitamin C, and prostaglandins, which nourish and activate sperm.
Accessory Glands and Scrotum
- Cowper's glands produce a thick, clear mucus that cleanses the urethra and serves as a lubricant during sexual intercourse.
- The scrotum is a divided sac of skin outside the abdomen, maintaining testes at 3°C lower than normal body temperature to protect sperm viability.
Penis
- The penis delivers sperm into the female reproductive tract and has regions including the shaft, glans penis (enlarged tip), and foreskin.
- Circumcision involves the removal of the foreskin, a practice often performed for religious, cultural, or hygiene reasons.
