Question

Spermatozoa are nourished during their development by

• A. Sertoli cell
• B. Interstitial cell
• C. Connective tissue cell
• D. Mast cell

Answer 1

Answer: (A)

Sertoli cell

• Each lobule of testes contains one to three seminiferous tubules in which the sperms are produced.
• Each seminiferous tubule is lined on its inside by two types of cells called male germ cells (spermatogonia) and Sertoli cells. Sertoli cells are also known as nurse cells.
• They provide nutrition to spermatozoa. Spermatozoa are developing sperms. It is formed during the last stage of spermatogenesis. This stage is known as spermiogenesis.
• In this step, spermatids are transformed into spermatozoa (sperms) by the process of metamorphosis. Heads of spermatozoa are embedded in the Sertoli cells.

So, the correct answer is 'Sertoli cell'.
