Ovary removal surgery, medically known as an oophorectomy, involves the surgical excision of one or both ovaries. The ovaries are small, almond-shaped organs located on either side of the uterus in the pelvic cavity, responsible for producing eggs and key reproductive hormones like estrogen and progesterone. When a surgeon removes one ovary, it is termed a unilateral oophorectomy; removing both is a bilateral oophorectomy. This procedure is a cornerstone of gynecological surgery, often performed to treat localized disease or to significantly reduce future health risks.

Why surgeons recommend ovary removal surgery

Clinical decisions to proceed with an oophorectomy are based on a variety of medical indications. For many, the surgery is a preventive measure. Individuals with high-risk genetic mutations, such as BRCA1 or BRCA2, may undergo a risk-reducing salpingo-oophorectomy (removal of both ovaries and fallopian tubes). Research indicates that for these high-risk populations, removing the ovaries around the age of 40 can drastically lower the incidence of both ovarian and breast cancers, providing a clear survival advantage.

Beyond cancer prevention, the surgery addresses acute and chronic conditions:

  • Ovarian Torsion: This occurs when an ovary twists around the tissues that support it, cutting off blood supply. It is a surgical emergency. While surgeons attempt to "untwist" and save the organ, severe necrosis (tissue death) often necessitates removal.
  • Endometriosis: In cases where endometrial-like tissue grows on the ovaries, forming painful cysts known as endometriomas, surgical intervention may be required if medical management fails.
  • Tubo-ovarian Abscess: This is a severe complication of pelvic inflammatory disease where a pus-filled pocket involves the fallopian tube and ovary. If antibiotics do not resolve the infection, the affected ovary may need to be removed.
  • Benign Neoplasms: Large cysts or non-cancerous tumors that cause persistent pain or risk of rupture are common reasons for elective ovary removal.

Surgical techniques: Laparoscopic vs. Open surgery

As of 2026, the approach to ovary removal surgery has become increasingly minimally invasive, though the choice depends on the patient's specific pathology and medical history.

Laparoscopic Oophorectomy

This is the most common method for benign conditions. The surgeon makes three to four small incisions (less than one inch each) in the abdomen. A laparoscope—a thin tube with a camera—is inserted, allowing the surgeon to visualize the pelvic anatomy on a high-definition monitor. Specialized tools are used to detach the ovary from the infundibulopelvic (IP) ligament and the uterine-ovarian ligament. The ovary is then placed in a retrieval bag and removed through one of the small incisions. Robotic-assisted laparoscopy is also a frequent choice, offering surgeons enhanced precision and a 3D view of the surgical field.

Laparotomy (Open Surgery)

An open procedure involves a larger abdominal incision, which may be vertical (from the navel down) or horizontal (a "bikini cut"). This approach is typically reserved for cases where the ovary is significantly enlarged, when there is a high suspicion of malignancy where rupturing the mass must be avoided, or when extensive scar tissue from previous surgeries complicates a laparoscopic approach. While effective, laparotomy requires a longer hospital stay and a more extended recovery period.

Anatomy and the surgical process

Understanding the blood supply is critical for a successful oophorectomy. The ovaries receive blood primarily via the ovarian artery, which branches directly from the aorta and travels through the IP ligament. Surgeons must also navigate the proximity of the ureter—the tube carrying urine from the kidney to the bladder—which runs very close to the ovarian vessels. Precisions in ligating these vessels while protecting the ureter and surrounding iliac vessels is a primary focus during the 45 to 90 minutes the procedure typically lasts.

General anesthesia is required for both laparoscopic and open methods. Patients are monitored closely for hemodynamic stability throughout the operation. If a malignancy is suspected, the surgeon may also perform a wash of the pelvic cavity to check for cancer cells or remove nearby lymph nodes for staging.

Preparing for the procedure

Preoperative care is essential for minimizing complications. Patients are generally instructed to fast (NPO - nothing by mouth) starting at midnight before the surgery. A thorough review of medications is necessary; blood thinners like aspirin or anticoagulants are usually paused several days in advance to reduce the risk of intraoperative bleeding. Depending on the reason for the surgery, imaging tests such as pelvic ultrasound or CT scans are performed to map the size and position of the ovaries.

For those of reproductive age, discussing fertility preservation is a vital part of the preparation. If only one ovary is removed, the remaining ovary typically continues to produce enough hormones and eggs for natural conception. However, a bilateral oophorectomy results in immediate infertility. Options such as egg or embryo freezing should be explored with a fertility specialist before the surgery date.

The recovery timeline: What to expect

Recovery varies significantly based on the surgical approach used.

Immediate Post-Op (The first 24-48 hours)

Most patients who undergo laparoscopic surgery can go home the same day. Those who have a laparotomy usually stay in the hospital for one to three days. Pain management typically involves a combination of anti-inflammatory medications (like ibuprofen or naproxen) and, in some cases, a short course of opioids for incision discomfort. It is common to experience shoulder pain after a laparoscopy due to the carbon dioxide gas used to inflate the abdomen during the procedure; this usually dissipates within 48 hours.

Short-Term Recovery (Week 1-2)

Patients can often return to sedentary work within 5 to 7 days following a laparoscopic procedure. For open surgery, this may take 4 to 6 weeks. Driving is permitted only when the patient is no longer taking opioid pain medication and can comfortably wear a seatbelt and perform an emergency stop. Light walking is encouraged from the first day to prevent blood clots, but heavy lifting (usually anything over 10 pounds) is restricted.

Long-Term Healing

Incisions should be monitored for redness, warmth, or drainage, which could indicate infection. While the external skin heals quickly, internal tissues take longer. Most patients are cleared for sexual activity and more strenuous exercise after their six-week follow-up appointment, provided the surgeon confirms the internal sutures are healing correctly.

Managing surgical menopause

When both ovaries are removed in a premenopausal individual, the body enters "surgical menopause." Unlike natural menopause, which occurs gradually over several years, surgical menopause is immediate and often more symptomatic because the body has no time to adjust to the sudden drop in estrogen and progesterone.

Symptoms and Complications

  • Vasomotor Symptoms: Hot flashes and night sweats are common and can be intense.
  • Genitourinary Syndrome: Vaginal dryness and discomfort during intercourse may occur due to thinning of the vaginal tissues.
  • Psychological Impact: Mood swings, anxiety, and depression are frequently reported as the endocrine system shifts.
  • Bone Density Loss: Estrogen plays a protective role in bone health. Without it, the risk of osteoporosis and subsequent fractures increases.
  • Cardiovascular Health: Early loss of ovarian hormones is associated with a higher risk of heart disease and changes in cholesterol levels.

Hormone Replacement Therapy (HRT)

For many individuals, especially those under the age of 45, healthcare providers suggest hormone replacement therapy to mitigate these risks. Low-dose estrogen can alleviate hot flashes and protect bone density. However, HRT is not suitable for everyone, particularly those with a history of certain hormone-sensitive cancers. Non-hormonal options, including SSRIs for mood and vasomotor symptoms or bisphosphonates for bone health, are alternative strategies discussed during post-operative consultations.

Potential risks and complications

While ovary removal surgery is generally safe, it is not without risk. Potential complications include:

  1. Infection: Both at the incision site and internally within the pelvis.
  2. Bleeding: Excessive blood loss may require a transfusion, though this is rare in elective cases.
  3. Organ Damage: Injury to the bladder, ureters, or bowel can occur, particularly in complex cases involving dense adhesions or endometriosis.
  4. Ovarian Remnant Syndrome: Occasionally, a small piece of ovarian tissue is inadvertently left behind. This tissue can remain hormonally active and cause persistent pelvic pain, sometimes requiring a secondary surgery.
  5. Adhesion Formation: Like any abdominal surgery, the healing process can create bands of scar tissue (adhesions) that may cause bowel obstructions or chronic pain later in life.

Life after surgery: Long-term outlook

For most, the long-term outlook after an oophorectomy is positive, particularly when the surgery successfully addresses chronic pain or reduces cancer risk. If one ovary remains, it usually compensates by producing sufficient hormones, and the transition to natural menopause will likely occur at a normal age.

For those who have had both ovaries removed, the focus shifts to proactive health management. Regular bone density scans (DEXA), cardiovascular screenings, and maintaining a calcium-rich diet become integral to post-surgical life. Modern medicine in 2026 emphasizes a holistic approach, where the surgical removal of the ovaries is just the beginning of a personalized health plan designed to maintain quality of life and longevity.

Patients are encouraged to maintain an open dialogue with their surgical team and primary care physician to navigate the physical and emotional changes that follow the procedure. While the surgery involves a significant change to the body’s reproductive and endocrine systems, the advancements in surgical technique and post-operative care have made it a manageable and often life-saving intervention.
