The Endocrine System, Female Physiology Before Pregnancy, and the Female hormones
Female Hormonal system: Gonadotropin-releasing hormone (GnRH) from the hypothalamus that stimulates FSH and LH secretion from the anterior pituitary. GnRH is inhibited by circulating estrogen and progesterone LH is secreted from the basophillic cells of the anterior pituitary gland and stimulates the development of the corpus luteum in the ovaries. FSH is secreted from the basophillic cells of the anterior pituitary gland in response to GnRH and stimulates the follicles in the ovaries. Estrogen and Progesterone are the steroid hormones secreted by the follicle and corpus luthium of the ovary. Corpus luteum x Section of the ovary. 1. Outer covering. 1’. Attached border. 2.
