What is "luteinizing hormone"?

Luteinizing hormone (LH) is a hormone produced by the pituitary gland that plays a vital role in the reproductive system. In females, LH triggers ovulation and promotes the production of progesterone. In males, it stimulates the production of testosterone. LH is essential for the proper functioning of the ovaries and testes, contributing to fertility and reproductive health.

Examples

1. Each month beginning around puberty, the hormone-producing pituitary gland in the brain starts releasing two substances into the blood: follicle stimulating hormone and luteinizing hormone.

2. And this tells the anterior pituitary to secrete follicle-stimulating hormone and luteinizing hormone into the blood, just like in females.

3. The other way that you can test ovulation at home is by using an ovulation kit which uses a hormone and it's looking for a surge and luteinizing hormone to see when ovulation is going to be triggered.
