Reproductive System
What is the function of luteinising hormone?
It stimulates the interstitial (Leydig) cells to produce testosterone.
It stimulates sustentacular (Sertoli) cells to produce sperm.
It stimulates the anterior pituitary to release follicle-stimulating hormone.
It stimulates the ovary to develop follicles.
It stimulates the interstitial (Leydig) cells to produce testosterone.
Luteinising hormone targets the interstitial cells of the testes inducing them to secrete testosterone. (In women a surge in LH triggers the completion of meiosis I, ovulation and the formation of corpus luteum.)
