What is the function of the male germ cells in the testis?
Options
- ATo undergo meiotic divisions and lead to sperm formation
- BTo provide nutrition to the Sertoli cells
- CTo line the inside of the seminiferous tubules
- DTo secrete testicular hormones
Correct answer
A. To undergo meiotic divisions and lead to sperm formation
Step-by-step solution
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
