What does LH and FSH do in a male?

In men, LH stimulates testosterone production from the interstitial cells of the testes (Leydig cells). FSH stimulates testicular growth and enhances the production of an androgen-binding protein by the Sertoli cells, which are a component of the testicular tubule necessary for sustaining the maturing sperm cell.

Considering this, what does FSH do in males?

In women, this hormone stimulates the growth of ovarian follicles in the ovary before the release of an egg from one follicle at ovulation. It also increases oestradiol production. In men, follicle stimulating hormone acts on the Sertoli cells of the testes to stimulate sperm production (spermatogenesis).

What do LH and FSH do?

FSH stimulates the ovarian follicle, causing an egg to grow. It also triggers the production of estrogen in the follicle. The rise in estrogen tells your pituitary gland to stop producing FSH and to start making more LH. The shift to LH causes the egg to be released from the ovary, a process called ovulation.

What does it mean to have low LH levels?

High levels of LH are normal if you are in menopause. Because LH triggers ovulation, low levels of LH can prevent ovulation and thus pregnancy. Low levels of LH are common in women with eating disorders, female athlete triad, high levels of stress and disorders of the pituitary or hypothalamus.
