Gonadal hormones are hormones produced by the gonads, which are the reproductive organs in males and females. In males, the primary gonadal hormone is testosterone, while in females, the main hormones are estrogen and progesterone. These hormones play crucial roles in regulating reproductive functions, sexual development, and secondary sexual characteristics. In addition to their roles in reproduction, gonadal hormones also influence other bodily functions. For example, estrogen helps maintain bone density and regulates the menstrual cycle, while testosterone affects muscle mass and mood. Overall, gonadal hormones are essential for both reproductive health and overall well-being.
