This estrogen peak tells the brain that the egg has matured and triggers the pituitary gland to release a surge of luteinizing hormone (LH). This LH surge acts as a cue to the ovarian follicle. The trial was designed to determine whether pituitary suppression of high endogenous luteinising hormone concentrations followed by low dose ovulation induction and luteal phase progesterone support improves the outcome of pregnancy in ovulatory women with recurrent miscarriage, polycystic ovaries, and hypersecretion of luteinising hormone.
