What organ produces hormones that promote female secondary sexual characteristics during puberty?

The ovaries are the correct organ responsible for producing hormones that promote female secondary sexual characteristics during puberty. Specifically, they secrete estrogen and progesterone, which play key roles in the development of features such as breast development, widening of hips, and the regulation of the menstrual cycle. As a young female enters puberty, the increase in estrogen production leads to these significant changes in the body, reflecting the transition into reproductive maturity.

Although other organs, such as the adrenal glands, do produce some hormones that can impact sexual development, the primary source of the hormones driving the prominent secondary sexual characteristics in females during puberty is the ovaries. The testes produce hormones primarily influencing male characteristics, while the hypothalamus regulates hormone release but does not directly produce sex hormones itself.
