Which one of the following is not a function of sertoli cells?
a. formation of a blood-testes barrier
b. production of primary spermatocytes
c. production of seminiferous tubule fluid
d. removal of damaged germ cells
e. synthesis of inhibin

The correct answer will be option-B.

Explanation:

Sertoli cells are the large somatic cells present in the testis which helps in the formation of spermatozoa. The Sertoli cells create a suitable environment for the production and maturation of the sperms as they produce certain molecules which nourishes the sperms.

The Sertoli cells act as a barrier between the testis and blood and secrete enzymes like inhibin. They eliminate the apoptotic germ cells and also produce seminiferous fluid to nourish the sperm. They do not play any role in primary spermatocytes.

Thus, Option-B is the correct answer.

oxygen = 21% of the atmosphere

nitrogen = 78%

carbon dioxide = 0.1%

argon =0.934%
