Which hormones are the primary hormones produced by the ovaries?

• A. Testosterone and progesterone.
• B. Testosterone and oxytocin.
• C. Estrogen and testosterone.
• D. Estrogen and progesterone.

Answer: (D)

The main idea is that the ovaries produce the two primary female sex steroid hormones that regulate the reproductive cycle and pregnancy: estrogen and progesterone. Estrogen, mainly in the form of estradiol, is produced by developing ovarian follicles and drives follicle growth and the thickening of the uterine lining, contributing to the development of female secondary sexual characteristics and the regulation of the menstrual cycle. After an egg is released, the remaining follicle forms the corpus luteum, which secretes progesterone. This hormone further thickens and maintains the endometrium to support potential implantation and early pregnancy. Other hormones listed aren’t the primary ovarian products. Testosterone is produced by the ovaries in small amounts (and in larger amounts by other tissues), but it is not the main ovarian hormone. Oxytocin is produced in the hypothalamus and released by the posterior pituitary, not produced by the ovaries.
