Egg donation surgery is a short, minimally invasive procedure that typically takes 15 to 30 minutes. A doctor uses an ultrasound-guided needle inserted through the vaginal wall to drain fluid from each mature follicle in the ovaries, collecting the eggs inside. The donor is sedated throughout and usually goes home the same day. But the surgery itself is only one piece of a process that starts weeks earlier with hormone injections and continues with a brief recovery period afterward.
Hormone Stimulation Before Surgery
Before the retrieval can happen, your ovaries need to produce multiple mature eggs in a single cycle instead of the usual one. To make that happen, you’ll give yourself daily hormone injections for 8 to 12 days. These medications stimulate your ovaries to develop many follicles at once, each one a small fluid-filled sac that ideally contains an egg. During this phase, you’ll visit the fertility clinic several times for blood draws and ultrasounds so the medical team can track how your follicles are growing and adjust your medication if needed.
When the follicles reach the right size, you’ll take a precisely timed “trigger shot” that signals the eggs to complete their final stage of maturation. The retrieval is then scheduled exactly 36 hours later. That timing is critical: too early and the eggs aren’t ready, too late and your body may release them on its own.
What Happens During the Retrieval
In the United States, about 95% of clinics use conscious sedation for egg retrieval, meaning you’re given intravenous medication that puts you into a light sleep. You won’t feel pain during the procedure and likely won’t remember it. Some clinics use general anesthesia or regional anesthesia instead, though no single approach has been shown to be clearly superior to the others.
Once you’re sedated, the doctor inserts a transvaginal ultrasound probe, which provides a real-time image of your ovaries on a screen. A thin aspiration needle (typically 17-gauge, roughly the width of an earring post) is attached to the probe and guided through the vaginal wall directly into each follicle. The needle connects to an aspiration pump that applies gentle suction, usually between 90 and 180 mmHg, to draw the follicular fluid out through a closed-circuit system into a collection tube.
Before the needle enters any follicle, the doctor uses the ultrasound image to confirm that no blood vessels, bowel, or bladder are in the needle’s path. The probe itself applies targeted pressure to push nearby structures out of the way. In rare cases, color Doppler imaging helps identify blood vessels that aren’t clearly visible on the standard ultrasound view. Each follicle is drained individually. The fluid travels directly to the embryology lab, where a specialist examines it under a microscope to identify and isolate the eggs.
The doctor works through one ovary, then the other, aspirating each visible follicle. The average donor cycle yields about 23 eggs, though individual results vary widely. National data shows that roughly 45% of donor retrievals produce between 11 and 23 eggs, while about 42% yield 24 or more.
Recovery in the First 24 Hours
After the procedure, you’ll rest in a recovery room for a few hours while the sedation wears off. Cramping and pressure in your lower abdomen are normal and expected. Some light spotting is also common. If you feel nauseous, clear liquids and crackers usually help.
You should plan to rest for at least the remainder of the day. Because sedation affects your coordination and judgment, you cannot drive for 24 hours after the procedure, so you’ll need someone to take you home. For pain, acetaminophen (two regular-strength tablets every six hours) and a heating pad on your abdomen are the standard recommendations. Most donors describe the discomfort as similar to menstrual cramps.
Activity Restrictions After Surgery
Your ovaries are still enlarged from the stimulation medications, which makes them more vulnerable to twisting or injury in the days that follow. On the day after your retrieval, you can walk and do light daily activities, but avoid heavy exercise, running, or any high-impact movement. Most clinics advise against sexual intercourse for two weeks after the procedure, both to protect the ovaries and because you may still be fertile from any eggs that weren’t retrieved.
Most donors feel back to normal within a week, though some bloating and mild tenderness can linger for several days. Your next menstrual period typically arrives one to two weeks after the retrieval.
Risks to Be Aware Of
Egg retrieval is considered safe, but it’s not risk-free. The most talked-about complication is ovarian hyperstimulation syndrome (OHSS), which happens when the ovaries overreact to the hormone medications. Moderate-to-severe OHSS occurs in roughly 1% to 5% of cycles. Mild cases involve bloating, nausea, and abdominal discomfort that resolves on its own. More serious cases can cause noticeable fluid buildup in the abdomen, significant swelling, and difficulty breathing.
Other potential complications from the retrieval itself include minor bleeding at the needle puncture site, infection, or, very rarely, injury to nearby organs. The ultrasound guidance used throughout the procedure is specifically designed to minimize these risks by giving the doctor a continuous view of the needle’s position relative to surrounding structures. Significant complications requiring hospitalization are uncommon.
Warning signs worth watching for in the days after surgery include severe abdominal pain, fever, heavy vaginal bleeding, or difficulty urinating. These can signal complications that need prompt medical attention.
