The hormone responsible for these changes is progesterone and it is manufactured by the corpus luteum. Progesterone: The corpus luteum is a cyst in the ovary that forms after release of an egg and produces Progesterone hormones. The ovum is released from the ruptured follicle called Graafian follicle. Luteinizing hormone (LH, also known as luteinising hormone, lutropin and sometimes lutrophin) is a hormone produced by gonadotropic cells in the anterior pituitary gland.The production of LH is regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus. It releases a hormone called progesterone that prepares your uterus for pregnancy. Estrogen and progesterone inhibit the release of a follicular stimulating hormone (FSH) and luteinizing hormone (LH).

The hormone responsible for these changes is progesterone and it is manufactured by the corpus luteum. The luteal phase lasts for 14 days. It is a pregnancy-promoting steroid hormone. The endometrium begins to degenerate as the progesterone levels drop, initiating the next menstrual cycle. At ovulation the follicle ruptures expelling the ovum into the fall. It also inhibits the release of FSH so that it may not develop additional follicles and eggs. The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that make .
