Answer:
GnRH
Explanation:
GnRH stimulates pituitary secretion of luteinizing hormone (LH) and follicle stimulating hormone (FSH). LH and FSH then stimulate the ovaries, resulting in the growth of secondary preantral follicles and ovulation.
Although some release hormones are also secreted in pulses, GnRH is unique because pulsed gonadotroph stimulation is necessary for normal LH and FSH synthesis and secretion, while continuous infusion of GnRH - or the use of such an agonist hormone that stimulates continuous infusion - results in negative modulation of gonadotropic responsiveness to GnRH. This property is clinically used to treat hormone-responsive conditions such as endometriosis and precocious puberty.
