3. Reproductive system

4. The reproductive system or genital system is a system of sex organs within an organism which work together for the purpose of sexual reproduction. Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system.

5. Female reproductive system

6. The female reproductive system is made up of the internal and external  sex organs  that function in reproduction of new offspring. In the human the female reproductive system is immature at birth and develops to maturity at puberty  to be able to produce  gametes, and to carry a  fetus  to  full term.

7. Male reproductive system

8. The male reproductive system includes the scrotum, testes, spermatic ducts, sex glands, and penis. These organs work together to produce sperm, the male gamete, and the other components of semen. These organs also work together to deliver semen out of the body and into the vagina where it can fertilize egg cells to produce offspring.

9. Testes

10. The testes (singular: testis), commonly known as the testicles, are a pair of ovoid glandular organs that are central to the function of the male reproductive system. The testes are responsible for the production of sperm cells and the male sex hormone testosterone. The testes produce as many as 12 trillion sperm in a male’s lifetime, about 400 million of which are released in a single ejaculation .

11. Anatomy of testes

12. Each testis is an oval structure about 5 cm long and 3 cm in diameter Covered by: tunica albuginea Located in the scrotum There are about 250 lobules in each testis. Each contains 1 to 4 -seminiferous tubules that converge to form a single straight tubule, which leads into the rete testis. Short efferent ducts exit the testes. Interstitial cells (cells of Leydig ), which produce male sex hormones, are located between the seminiferous tubules within a lobule.

13. Function of testes

14. * Sperm are produced in the seminiferous tubules of the testes. * The main hormone secreted by the testes is testosterone, an androgenic hormone .
