Luteinizing hormone (LH, lutropin or lutrophin) is a sex hormone produced by gonadotroph cells in the anterior pituitary gland.
In females, an LH surge triggers ovulation and development of the corpus luteum (a temporary endocrine structure in female mammals that promotes relatively high levels of progesterone). In males, where LH had also been called interstitial cell–stimulating hormone (ICSH),[1] it stimulates Leydig cell production of testosterone. It acts synergistically with Follicle-stimulating hormone (FSH).
