Feedback control. Reproductive function is controlled by steroids from the gonads. These are produced by specific cells in the ovary and testis, which respond to pituitary gonadotrophins — luteinising hormone (LH) and follicle stimulating hormone (FSH). As with many other hormones, sex steroids inhibit secretion of their trophic hormones (negative feedback). Under a specific set of circumstances, oestrogen may stimulate secretion of gonadotrophins (positive feedback).
