Which organs are responsible for the release of oestrogen and progesterone?

The ovaries are the primary organs responsible for the production and release of the hormones estrogen (also spelled oestrogen) and progesterone. These hormones play crucial roles in the female reproductive system, regulating the menstrual cycle, supporting pregnancy, and influencing various physiological processes related to reproduction and overall health.

Estrogen is involved in the development and maintenance of female secondary sexual characteristics and the regulation of the menstrual cycle, while progesterone is vital for preparing the uterus for potential pregnancy and maintaining it if fertilization occurs. This hormonal interplay is essential in female reproductive health.

Other options, while they may produce hormones, do not primarily secrete estrogen and progesterone. The adrenal glands mainly produce adrenal hormones like cortisol and adrenaline, the pituitary gland is primarily responsible for releasing hormones that regulate other glands but does not produce these specific sex hormones, and the testes are responsible for producing testosterone, which is more relevant to male physiology. Thus, the ovaries uniquely fulfill the role of releasing the mentioned hormones in females.
