Reproductive hormones are chemical messengers that play a crucial role in regulating the reproductive system in both males and females. In females, key hormones include estrogen and progesterone, which control the menstrual cycle and support pregnancy. In males, testosterone is the primary hormone responsible for the development of male characteristics and sperm production. These hormones are produced by various glands, including the ovaries in females and the testes in males. They influence a range of functions, such as sexual development, fertility, and libido. Proper balance of these hormones is essential for reproductive health and overall well-being.
