The short answer
Surgical menopause happens when both ovaries are removed (bilateral oophorectomy) before natural menopause. Hormone levels drop within days, so symptoms can be sudden and strong. For people under about 45 without a contraindication, guidelines generally recommend hormone therapy until the average age of menopause. Hysterectomy alone, with ovaries kept, does not cause immediate menopause.

What happens after surgery
| Surgery | Effect on menopause |
|---|---|
| Hysterectomy, ovaries kept | Periods stop but hormones continue; menopause may come a little earlier |
| Removal of one ovary | Usually no immediate menopause |
| Removal of both ovaries (bilateral oophorectomy) | Immediate surgical menopause |
| Risk-reducing salpingo-oophorectomy (BRCA) | Immediate surgical menopause, planned in advance |
Symptoms to expect
- Hot flashes and night sweats, often more intense than in natural menopause
- Sleep disruption and fatigue
- Mood changes and brain fog
- Vaginal dryness and lower libido
- Joint aches
Hormone therapy after surgery
For people under about 45, guidelines generally recommend hormone therapy until around 51, to relieve symptoms and protect bone and heart health. It can often start soon after surgery, once your surgeon agrees. If the uterus was removed, estrogen alone is usually used. If it remains, a progestogen is added. Transdermal estradiol is often chosen for people with clot risk factors.
If the surgery was for endometriosis, a clinician may consider adding a progestogen even without a uterus. If it was for an estrogen-sensitive cancer, non-hormonal options are usually used instead.
Risk-reducing surgery for BRCA
Women with BRCA1 or BRCA2 variants are often advised to have their ovaries and tubes removed, typically between 35 and 45. For carriers who have not had breast cancer, current evidence and The Menopause Society support hormone therapy until the average age of menopause, as it does not appear to cancel out the risk reduction from surgery. Discuss timing and planning with your surgeon and genetics team before surgery.
Long-term health
- Bone density scan, especially if hormone therapy is not used
- Regular blood pressure, cholesterol and glucose checks
- Vaginal estrogen or moisturizers for genitourinary symptoms
- Discussion of testosterone for persistent low desire

Questions, answered
Common questions
How soon do symptoms start after oophorectomy?
+
Often within a few days, as estrogen falls sharply. Planning hormone therapy or non-hormonal options before surgery can help you start treatment promptly.
Does a hysterectomy cause menopause?
+
Not if the ovaries are kept. Periods stop, but the ovaries keep making hormones. Menopause may arrive somewhat earlier than it otherwise would.
Do I need progesterone after a hysterectomy?
+
Usually not. Progestogen protects the uterine lining, so estrogen alone is typical after hysterectomy. Exceptions include some people with a history of endometriosis.
Can BRCA carriers take HRT after ovary removal?
+
For carriers without a personal history of breast cancer, guidelines generally support hormone therapy until about the average age of menopause. Decisions involve your surgeon and genetics team.
How long should I take hormone therapy after surgical menopause?
+
For surgery before about 45, typically until around 51, the average age of natural menopause. After that, continuing is an individual decision reviewed with your clinician.
