LH

Luteinizing Hormone (LH) is the body's essential chemical messenger, directing key functions in both the male and female reproductive systems. Secreted by the pituitary gland, this hormone actively signals the ovaries to facilitate follicle development and trigger ovulation, while in men, it spurs the production of vital testosterone. An LH level test provides critical insight into fertility issues, irregular periods, low sex drive, and the function of your pituitary gland or hypothalamus. Understanding your LH levels can help diagnose conditions like PCOS or Kallmann syndrome, giving you the necessary information to take control of your reproductive health and development.
