The ovaries are the primary source of estrogen in women during their reproductive years. However, estrogen is also produced by the adrenal glands (located on the kidneys) and adipose tissue (body fat). Even men produce small amounts of estrogen in these locations.
Estrogen Production: A Detailed Look
Several glands and tissues contribute to estrogen production:
- Ovaries: These are the main estrogen producers in women of reproductive age. [Source: Cleveland Clinic, Endocrine Society, Medical News Today]
- Adrenal Glands: These glands, situated atop the kidneys, also secrete estrogen, albeit in smaller quantities than the ovaries. [Source: Cleveland Clinic, Canadian Cancer Society, Medical News Today]
- Adipose Tissue (Body Fat): Body fat also converts androgens (male hormones) into estrogen. This process is more significant in postmenopausal women and men. [Source: Cleveland Clinic, Medical News Today]
- Placenta (during pregnancy): The placenta plays a significant role in estrogen production during pregnancy. [Source: NCBI PMC]
- Testes (in men): While primarily associated with testosterone production, the testes also produce a small amount of estrogen. [Source: Physiological Reviews, NCBI PMC]
Note: The amount of estrogen produced varies depending on age, sex, and overall health.
