Luteinizing Hormone (LH) Blood Test

Luteinizing Hormone is a hormone produced by the anterior pituitary gland in the brain. It plays a vital role in sexual development and functioning for both men and women.

In women LH is essential for regulating the menstrual cycle. It triggers ovulation, the process where an egg is released from the ovary. This hormone level fluctuates throughout the month, peaking just before ovulation. In men, LH stimulates the production of testosterone in the testes. Testosterone is crucial for sperm production and maintaining male reproductive health. 

When you LH levels are not as expected, it can cause infertility, problems with your menstrual cycle and low sex drive in men.
