The stimulation for proliferation of new follicles in the ovary is influenced by the hormone _____.
Options:
Answer:
Solution:
The proliferation and development of new ovarian follicles during the menstrual cycle is primarily regulated by gonadotropins, specifically Follicle-Stimulating Hormone (FSH).
The synthesis and secretion of these gonadotropins from the anterior pituitary gland are directly stimulated and regulated by Gonadotropin-Releasing Hormone (GnRH), which is released by the hypothalamus.
Gonadotropin-Releasing Hormone (GnRH) is the correct choice because it serves as the master upstream hormone that induces the secretion of the gonadotropins necessary for follicular growth.
Among the other options, LH is primarily responsible for inducing ovulation and maintaining the corpus luteum, hCG is a pregnancy-associated hormone that maintains the corpus luteum after implantation, and ANH is a peptide hormone secreted by the heart to regulate blood pressure and sodium balance.
Answer: GnRH
