Which statement is correct about Spermatogenesis?
High levels of FSH and LH inhibit Testosterone production
Testosterone stimulates the release of FSH and LH
GnRH inhibits secretion of FSH and LH from the anterior pituitary gland
Rising Testosterone levels causes Inhibin secretion
Answers

The correct statement about spermatogenesis is:
**Rising Testosterone levels causes Inhibin secretion**
Inhibin is a hormone produced by Sertoli cells in the testes, and it is involved in the negative feedback regulation of FSH secretion. Rising levels of testosterone can stimulate the release of inhibin, which in turn helps regulate spermatogenesis.
Let's clarify the other statements:
- High levels of FSH and LH actually stimulate testosterone production rather than inhibit it.
- Testosterone does not stimulate the release of FSH and LH; it is mainly regulated by GnRH from the hypothalamus.
- GnRH actually stimulates the secretion of FSH and LH from the anterior pituitary gland, rather than inhibiting it.
