Clinical significance of test
Luteinizing hormone (LH) is made by your pituitary gland, a small gland located underneath the brain. LH plays an important role in sexual development and functioning. LH works closely with another hormone called follicle-stimulating hormone (FSH) to control sexual functions In women, LH helps control the menstrual cycle. It also triggers the release of an egg from the ovary. This is known as ovulation. LH levels quickly rise just before ovulation. In men, LH causes the testicles to make testosterone, which is important for producing sperm. Normally, LH levels in men do not change very much. In children, LH levels are usually low in early childhood, and begin to rise a couple of years before the start of puberty.
