…ovulation and development of the corpus luteum. In males, where LH had also been called interstitial cell stimulating hormone (ICSH), it stimulates Leydig cell production of testosterone. It acts synergistically with follicle-stimulating hormone (FSH). The term luteinizing comes from the Latin "luteus", meaning…
