Luteinizing hormone (LH) is a pivotal player in our body’s endocrine system, particularly impacting reproductive health. It is produced by the pituitary gland and plays a crucial role in regulating the function of the ovaries in females and the testes in males. In females, LH is instrumental in triggering ovulation and maintaining the menstrual cycle. In males, it stimulates the production of testosterone, a hormone essential for sperm production.
