Causes ovulation and causes the ruptured follicle to develop into a corpus luteum It stimulates the growth of the endometrium lining Inhibits the development of another follicle by inhibiting FSH Stimulates the development of follicles which in turn leads to estrogen secretion, which in turn inhibits FSH 8.
