Sex hormones are secreted by which organs?

• A. Secreted by gonads
• B. Secreted by adrenal glands
• C. Secreted by pancreas
• D. Secreted by thyroid

Answer: (A)

Sex hormones are produced primarily by the gonads—the ovaries in females and the testes in males. The ovaries secrete estrogen and progesterone, while the testes secrete testosterone. These hormones regulate puberty, reproductive function, and the development of secondary sexual characteristics. The adrenal glands do produce some androgens, but they are not the main source of sex hormones. The pancreas and thyroid do not secrete sex hormones at all. So the organs responsible for sex hormones are the gonads.
