interstitial cell-stimulating hormone
(IN-ter-STIH-shul sel-STIM-yoo-LAY-ting HOR-mone)
A hormone made in the pituitary gland. In females, it acts on the ovaries to make follicles release their eggs and to make hormones that get the uterus ready for a fertilized egg to be implanted. In males, it acts on the testes to cause cells to grow and make testosterone. Also called LH, luteinizing hormone, and lutropin.
