In one step of this process, antral granulosa cells secrete a compound which suppresses gnRH release at high concentration and also promotes angiogenesis in the endometrium.
In one step of this process, antral granulosa cells secrete a compound which suppresses gnRH release at high concentration and also promotes angiogenesis in the endometrium. One step of this cycle sees the development of a yellow body which may be preserved by human chorionic gonadotropin. That body, which is generated in response to FSH and LH, is called the corpus luteum, and secretes progesterone. During this cycle, the follicle bursts, releasing an ovule which may implant in the uterus. For 10 points, name this 28-day cycle which occurs in pre-menopausal non-pregnant women and which can end in the discharge of excess uterine lining via bleeding.
