It's option C FSH(follicle stimulating hormorne)..damn sure about this..!!👍👍😊

Introduction:
Spermatogenesis is the process of producing mature sperm cells in the testes. It is a tightly regulated process that requires the proper balance of hormones to ensure normal development and maturation of spermatozoa. Inhibin is a hormone that plays a key role in regulating spermatogenesis by providing negative feedback to the pituitary gland.

Role of Inhibin:
Inhibin is primarily produced by the Sertoli cells in the testes. Its main function is to suppress the secretion of follicle-stimulating hormone (FSH) from the anterior pituitary gland. FSH is a hormone that stimulates the production of sperm cells and promotes their maturation. By inhibiting FSH secretion, inhibin helps maintain the balance of spermatogenesis and prevents excessive production of sperm cells.

Effect on LH and Testosterone:
While inhibin primarily acts on FSH secretion, it indirectly affects luteinizing hormone (LH) and testosterone levels as well. LH is another hormone produced by the pituitary gland that stimulates the production of testosterone in the Leydig cells of the testes. Testosterone is essential for the development and maintenance of male reproductive tissues, as well as the secondary sexual characteristics.

When inhibin is released in response to rapid spermatogenesis, it suppresses FSH secretion, which in turn reduces the production of testosterone. This occurs because FSH is responsible for stimulating the Leydig cells to produce testosterone. Therefore, when FSH levels decrease due to inhibin's inhibitory effect, the production of testosterone also decreases.

Effect on Intestinal Cell Stimulating Hormone:
The option (D) "intestinal cell stimulating hormone" is not a hormone directly involved in spermatogenesis or the regulation of testosterone. It is likely a distractor in this context and not directly affected by inhibin.

Conclusion:
In summary, when spermatogenesis proceeds too rapidly, inhibin is released from Sertoli cells. Inhibin primarily acts to suppress FSH secretion, which indirectly reduces the production of testosterone. This negative feedback mechanism helps maintain the balance of spermatogenesis and prevents excessive production of sperm cells.
