Androgens are a group of hormones that play a key role in male traits and reproductive activity. The most well-known androgen is testosterone, which is produced mainly in the testes in males and in smaller amounts in females' ovaries and adrenal glands. These hormones are responsible for the development of male characteristics, such as facial hair, deep voice, and muscle growth. In addition to their role in male development, androgens also influence various functions in both men and women, including libido and bone density. An imbalance in androgen levels can lead to health issues, such as polycystic ovary syndrome (PCOS) in women or hypogonadism in men, affecting overall well-being.
