The Correct answer is Leydig cells

Key Points

  • The male reproductive system includes a pair of testes along with accessory ducts, glands and the external genitalia.
  • Each testis has about 250 compartments called testicular lobules.
  • Each lobule contains one to three highly coiled seminiferous tubules in which sperms are produced.
  • Each seminiferous tubule is lined on its inside by two types of cells called male germ cells (spermatogonia) and Sertoli cells.
  • The male germ cells undergo meiotic divisions finally leading to sperm formation, while Sertoli cells provide nutrition to the germ cells.
  • The regions outside the seminiferous tubules called interstitial spaces, contain small blood vessels and interstitial cells or Leydig cells. 
  • Leydig cells synthesise and secrete testicular hormones called androgens.
