Luteinising Hormone (LH)

The roles of luteinising stimulating hormone are slightly different in men and women:

The actions of luteinising stimulating hormone in men include:

Stimulating testosterone production from the interstitial cells of the testes (Leydig cells);

Luteinizing hormone (and also follicle stimulating hormone) are essential for the maturation of spermatoza - i.e. mature male sex cells.

The actions of luteinising stimulating hormone in women include:

Stimulating oestrogen and progesterone production from the ovary: A surge of luteinising hormone midway through the menstrual cycle leads to ovulation. Continued secretion of luteinising hormone stimulates the corpus luteum to produce progesterone.

In conjunction with follicle stimulating hormone, controlling the secretion of oestrogen from ovarian follicles.
