Estrogen is an important hormone that regulates many functions in the female body. During a woman's reproductive years, estrogen is essential for sexual development, regulating the menstrual cycle, and preparing the body for pregnancy.
Estrogen levels naturally rise and fall throughout a woman's menstrual cycle. However, during perimenopause and menopause, a woman’s ovaries produce less estrogen due to loss of ovarian follicles. This drop in estrogen leads to symptoms like hot flashes, night sweats, vaginal dryness, irregular periods, trouble sleeping, and mood changes.
After menopause, estrogen levels remain low but small amounts of estrogen continue to be produced in fat tissues and adrenal glands. While ovarian production of estrogen slows during menopause, some women may experience a temporary rise in estrogen levels years later due to:
- Ovarian follicles that return - In some cases, ovarian follicles that were resistant to change during menopause can reawaken later and produce small surges of estrogen.
- Cancerous tumors - Conditions like endometrial hyperplasia or cancers can increase estrogen. This estrogen is not from the ovaries restarting normal function.
- Hormone medications - If a woman takes hormone replacement therapy or medications/supplements like soy, black cohosh, DHEA etc., this can increase estrogen levels temporarily.
Does this mean estrogen comes “back” or menstruation restarts after menopause?
The short answer is
no. True reawakening of ovarian estrogen function does not happen after menopause naturally. Any rises in estrogen later are usually temporary.
Reasons estrogen does NOT return to premenopausal levels:
- Ovaries have very few follicles left after menopause so they cannot sustain high estrogen production
- The hormonal feedback systems that control ovarian function and menstruation are permanently altered after menopause
- After 12 months without a period, a woman is considered to have gone through menopause
In rare cases, some women can experience “spontaneous reversal of menopause” where ovarian activity resumes and menstruation returns years after menopause. But this is very rare:
- A 1999 study found reversal of menopause in 0.04% of women
- A 2009 study found the phenomenon in 0.007% of women
So while small temporary rises in estrogen can happen after menopause, true reversal leading to the ovarian production seen during the reproductive years is unlikely. The hormonal changes of menopause are generally permanent.
