Definition
A sex gland, also known as a gonad, is a gland that produces gametes (sex cells) and sex hormones. In males, these are the testes, producing sperm and testosterone. In females, these are the ovaries, producing eggs and estrogen/progesterone. These glands are essential for sexual development, reproduction, and the maintenance of secondary sexual characteristics. Think of sex glands as the architects of puberty, orchestrating the changes that transform you into an adult. They're the body's engine for reproduction and sexual function.
