Which statement about the ovaries is correct?

The ovaries play a crucial role in the female reproductive system, primarily through their function in hormone regulation. They produce key hormones such as estrogen and progesterone, which are vital for the menstrual cycle, ovulation, and overall reproductive health. These hormones are responsible for regulating various physiological processes, including the development of secondary sexual characteristics and the management of the menstrual cycle.

The other options do not accurately describe the function of the ovaries. For instance, the production of sperm is a function associated with male reproductive organs, specifically the testes. The facilitation of the birth process primarily involves structures such as the uterus and cervix rather than the ovaries. Moreover, stating that the ovaries are not involved in the reproductive system contradicts their fundamental role in female reproduction as they are essential for egg production and hormonal balance. Thus, the accurate characterization of the ovaries is that they are indeed responsible for hormone regulation, making this statement correct.
