Which organs are the gonads?

Which organs are the gonads?

• A. Testes and ovaries.
• B. Hypothalamus and pituitary.
• C. Adrenal glands.
• D. Thyroid glands.

Answer: (A)

Gonads are the primary sex organs that produce gametes and sex hormones. In humans, the organs that do this are the testes in males, which make sperm and testosterone, and the ovaries in females, which produce eggs and hormones like estrogen and progesterone. The other options are important endocrine glands but serve different roles: the hypothalamus and pituitary regulate gonadal function but are not gonads themselves; the adrenal glands produce corticosteroids and some androgens but are not the main gamete-producing organs; and the thyroid gland controls metabolism with thyroid hormones, not gamete production.
