Removing the uterus can bring menopause years early, even when ovaries stay
Hysterectomy, surgical removal of the uterus, is usually reserved for severe problems like fibroids, endometriosis or cancer once other options fail. Its effects ripple outward: menopause arrives on average 3.7 years sooner even when the ovaries are kept, and ovary function is significantly affected in roughly 40 percent of patients.
A standard hysterectomy takes out the uterus and cervix, while a supracervical operation spares the cervix. Surgeons may also remove the ovaries or fallopian tubes. The everyday labels 'partial' and 'total' are misleading, because they are often used to mean whether ovaries went too, which is not what the medical terms describe. Any version ends the ability to carry a pregnancy.
Reasons include benign fibroids, endometriosis and adenomyosis, heavy bleeding, prolapse, gynaecological cancers, preventive surgery for people with BRCA mutations, emergencies after childbirth, and gender-affirming care for trans men. Using it to sterilise people with severe developmental disabilities is highly controversial, and some US state supreme courts have ruled such cases violated patients' rights. Most patients treated for benign conditions report better sex lives and less pelvic pain afterwards, though a minority fare worse.
Short-term risk is low: in 1995, deaths within 40 days of surgery for benign reasons ran at 0.38 per 1,000. Pregnancy, cancer or other complications raise that several-fold. Injuries to the ureter occur in 0.2 per 1,000 vaginal operations and 1.3 per 1,000 abdominal ones. Abdominal surgery keeps patients in hospital three to five days, against one or two for vaginal or laparoscopic routes, and about 3 percent of abdominal wounds become infected. Around 35 percent of women need a related operation within two years.
Longer-term effects are subtler. Removing the ovaries causes an abrupt 'surgical menopause', a hormonal shock unlike the gradual natural decline, and strips away estrogen's protection for heart and bone. Studies link the operation at age 50 or younger to higher cardiovascular risk, and link hysterectomy generally with osteoporosis and fractures. Urinary incontinence risk roughly doubles within 20 years, vaginal prolapse becomes about twice as likely, and one review found adhesion-related bowel blockage in 15.6 percent of open abdominal operations versus none after laparoscopic ones.
