Luteinizing hormone (LH) triggers a chain of events in the menstrual cycle. LH stimulates the ovary to release the ovum. This point in the menstrual cycle is called ovulation. Implantation is the attachment of a fertilized ovum to the uterine lining. If fertilization (when a sperm and an ovum combine to create an embryo) does not occur, the progesterone level decreases, the endometrium sloughs off, and the woman experiences menstruation.
