Question

Draw a neat labelled diagram of human male reproductive system. [3 MARKS]

Answer 1

Male reproductive system:

1. The male reproductive system includes the testes, scrotum, spermatic ducts, male accessory glands, and penis.
2. All these organs work together to produce sperms, the male gamete, male sex hormones and other components of semen.
3. Penis is the male external genitalia.
4. The foreskin covers the enlarged end of the penis called glans penis.
5. Scrotum is a sac of thick skin that protects and surrounds the testes. It also controls the temperature of the testes, $2^{o}C$ lower than the body temperature, essential for sperm production. So, they are situated outside the body.
6. A pair of testes are present in humans. Testes are present outside the body in a pouch called the scrotum.
7. The sperm production and the testosterone are produced in the testes.
8. It is a tube-like structure that connects the urinary bladder to the urinary meatus. In males, the urethra travels through the penis and is mainly involved in two main functions- passage of the urine and the passage of the semen.
9. The male accessory glands include seminal vesicles, prostate and bulbourethral glands.
