Lutropin (LH)
LH (Luteinizing Hormone) is produced in the pituitary gland and controls important reproductive processes. In women, a sudden increase in LH in the middle of the cycle triggers ovulation. In men, LH stimulates the testes to produce testosterone.
Deviating LH levels can indicate disorders of the ovaries, testes, or the hormonal control centers in the brain. The LH test is often used in cases of unfulfilled desire for children or in cycle and puberty disorders.
