• C. It is produced by the ovary and inibits the secretion of LH.
• D. None of the above

Answer 1

The correct option is B It is produced by the ovary and it inhibits the secretion of FSH.

Inhibin and activin are secreted by both testes and ovaries. They regulate the the secretion of FSH (follicle stimulating hormone) and GnRH (gonadotropin-releasing hormone) by the anterior pituitary and the hypothalamus, respectively. Activin upregulates the secretion of FSH and GnRH, while inhibin downregulates it.
