nataly862011 [7]

Answer:

decrease kisspeptin synthesis

Explanation:

Kisspeptin is a protein involved in the regulation of gonadotropin-releasing hormone (GnRH): it stimulates the secretion of GnRH. GnRH than stimulate the release of gonadotropins such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland. FSH stimulates the  production of estrogens by the granulosa cells of the ovarian follicles.

In negative feedback system, high levels of estrogen will bind to their receptors on neurons that release kisspeptin and inhibit its further release.
