Luteinizing Hormone

Luteinizing hormone (LH) is a key hormone produced by the pituitary gland in the brain. In women, it plays a crucial role in regulating the menstrual cycle and triggering ovulation, which is when an egg is released from the ovary. In men, LH stimulates the production of testosterone, which is important for sperm production and overall male reproductive health. LH levels fluctuate throughout the menstrual cycle and can be measured in blood tests, making it important for assessing fertility and other reproductive health issues in both genders.
