Luteinising Hormone “LH” is also known by the names Interstitial cell-stimulating hormone, lutropin and LH. Like the follicle-stimulating hormone (FSH), luteinising hormone is a gonadotropic hormone produced and released by cells in the anterior pituitary gland.
It plays a vital role in regulating the function of testes in men and ovaries in women. In males, the luteinising hormone stimulates the Leydig cells in the testes to start the production and release of testosterone, which acts in the area to aid with sperm production in the scrotum. Testosterone also has a host of other functions in the body. It is required to generate typical male physical characteristics like the enlargement of the larynx, muscle mass, develop a deep voice and the growth of facial and body hair.
The luteinizing hormone carries out two different functions in the menstrual cycles two distinct halves in women. In the first couple of weeks of the cycle, the hormone is required to stimulate the ovarian follicles in the ovary to produce a sex hormone called oestradiol. The LH also stimulates the corpus luteum to produce progesterone, another hormone required by the female body if the egg gets fertilized.
