Which hormones are secreted by the ovaries?

• A. Estrogen and progesterone
• B. Testosterone and insulin
• C. Adrenaline and cortisol
• D. Thyroxine and calcitonin

Answer: (B)

Ovaries secrete estrogen and progesterone. Estrogen (primarily estradiol) promotes follicle development, supports the growth and maintenance of female secondary sexual characteristics, and helps regulate the menstrual cycle by influencing the uterine lining. Progesterone, produced mainly after ovulation by the corpus luteum, prepares the uterus for implantation and maintains early pregnancy. The other hormone pairs come from different glands: insulin is produced by the pancreas; adrenaline and cortisol come from the adrenal glands; thyroxine and calcitonin come from the thyroid. The ovaries do make small amounts of androgens like testosterone, but the principal ovarian hormones are estrogen and progesterone.
