Luteinizing hormone is one of the hormones that regulate the human reproductive system. This critical hormone, which plays various roles in males and women's bodies, is essential for maintaining a healthy reproductive system. Understanding this important hormone is necessary for taking control of your reproductive health.
What is the luteinizing hormone?
The pituitary gland produces the hormone, luteinizing hormone (LH). The pituitary gland is a small gland at the base of the brain that is roughly the size of a pea. LH is a crucial aspect of the menstrual cycle for women. It operates in conjunction with follicle-stimulating hormone (FSH), a gonadotropin produced by the pituitary gland. FSH stimulates the ovarian follicle, which causes an egg to grow. It also stimulates the follicle's production of oestrogen.
What is the function of the luteinizing hormone?
The hormone causes the ovaries to create oestradiol in women. A rise in luteinizing hormone occurs two weeks into a woman's cycle, causing the ovaries to release an egg during ovulation. If fertilisation takes place, the luteinizing hormone causes the corpus luteum to release progesterone, which is required to keep the pregnancy going.
Luteinizing hormone boosts testosterone production in the Leydig cells of men's testes. Testosterone boosts sperm production and male characteristics like deep voice and facial hair growth.
What difficulties might luteinizing hormone cause?
Because the hormone directly affects the reproductive system, those with excessive amounts of luteinizing hormone may have infertility. Luteinizing hormone levels that are excessively high in women are frequently linked to polycystic ovarian syndrome, which results in testosterone levels that are too high. High amounts of the hormone can also be caused by hereditary diseases like Turner syndrome or Klinefelter syndrome. People who suffer from these diseases are frequently unable to reproduce.
Low levels of the luteinizing hormone can also lead to infertility because they prevent sperm from being produced or the ovulation process from taking place. In women, too little luteinizing hormone prevents ovulation, whereas, in men, it causes a lack of gonadotrophin-releasing hormone (GnRH) release.
