Explain the structure of male reproductive system with help of a diagram?


The male reproductive system is located in the pelvic region. It consists of:

  • A pair of testes
  • Accessory glands and ducts
  • External genitalia

Testes: These are present within the scrotum, which protects the testes and also helps in maintaining the temperature. It has around 250 compartments known as testicular lobules which contain seminiferous tubules. Seminiferous tubules are sites for the formation of sperms. They have male germ cells and Sertoli cells (for providing nourishment to germ cells). Outside the seminiferous tubules is a region called interstitial space which contains Leydig cells. These cells help in the production of androgens.

Accessory Ducts and Glands

  • The ducts include ​​​​​Rete testis, Vasa efferentia, Epididymis and Vas deferens.
  • Through rete testis, seminiferous tubules open into the vasa efferentia which opens into epididymis which ways to vas deferens. The vas deferens open into urethra along with ejaculatory duct. This duct has stored sperms.

Accessory glands include a pair of seminal vesicles, Prostate gland and a pair of bulbourethral glands.The secretions of these glands make up the seminal plasma, and provide nutrition and a medium of motility to the sperms.​​
