What Organ Produces Estrogen?

Published in Hormone Production 1 min read

The primary organs that produce estrogen are the ovaries, though other sources contribute as well.

Main Estrogen Producing Organs

Ovaries

  • During a woman's reproductive years, the ovaries are the primary source of estrogen.
  • They release this hormone as a crucial part of the menstrual cycle.

Secondary Estrogen Producing Areas

While the ovaries are the main source, other areas also produce estrogen:

  • Adrenal Glands: These are located above the kidneys and secrete estrogen, though in smaller amounts compared to the ovaries.
  • Adipose Tissue: Body fat, or adipose tissue, can also secrete estrogen. This is particularly relevant after menopause, when ovarian production declines.

Estrogen Production Summary

Organ Estrogen Production Notes
Ovaries Main source Primarily during reproductive years
Adrenal Glands Secondary source Glands above the kidneys
Adipose Tissue Secondary source Body fat

In summary, while the ovaries are the primary producers of estrogen, the adrenal glands and adipose tissue also contribute, particularly after menopause when ovarian production declines.
