(N/A) The production of sperms in the testes takes place in highly coiled structures called seminiferous tubules. These tubules are located within the testicular lobules.
Each seminiferous tubule is lined on its inside by two types of cells: male germ cells (spermatogonia) and Sertoli cells.
The male germ cells (spermatogonia) 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 synthesize and secrete testicular hormones called androgens (mainly testosterone).
