Egg Retrieval Procedure: How It Works and How to Prepare

Egg retrieval is the final step of an egg donation cycle, the day all of the injections and monitoring appointments lead up to. For many first-time donors it is also the step that brings up the most questions, because it is a medical procedure with anesthesia.

Knowing exactly what happens can make the day feel far less intimidating. This guide explains how the egg retrieval procedure works, when it is scheduled, how to prepare, and what the research says about safety.

What is the egg retrieval procedure?

Egg retrieval, also called follicular aspiration, is a minor surgical procedure that collects mature eggs from the ovaries. Using ultrasound images as a guide, the doctor inserts a thin needle through the vagina into each ovary and the fluid-filled sacs (follicles) that hold the eggs. The needle is connected to a suction device that draws out the fluid and egg from each follicle, one at a time.¹

You receive medication so you do not feel pain during the procedure.¹ Because the needle reaches the ovaries through the vaginal wall, there are no cuts or stitches on your abdomen.

When does egg retrieval happen?

Retrieval happens at the end of the stimulation phase. After 10 to 12 days of fertility injections, with monitoring appointments about every other day in the morning, your doctor decides when your follicles are ready. You then take a trigger shot, which starts the final maturation of your eggs, and retrieval is scheduled about 32 to 36 hours later.

That window is precise. Taking the trigger shot at the exact time your clinic gives you keeps the eggs from being released before the procedure.

How should you prepare for egg retrieval?

Preparation is mostly about following your clinic's instructions and planning your day. These steps help:

• Follow your medical instructions: your clinic will tell you when to stop eating and drinking before anesthesia, which medications to take, and what activities to avoid.
• Arrange a ride and a companion: you cannot drive after anesthesia. If you travel for your cycle and do not have a companion, Donor Nexus arranges a private nurse through our NurseRegistry partnership, and travel and lodging are covered separately from your compensation.
• Remove nail polish and acrylics: a monitor on your finger measures your oxygen level during the procedure, and polish can interfere with it.
• Plan an easy day: clear your schedule for the rest of retrieval day so you can rest at home.

Many donors also tell us that understanding each step ahead of time helps them feel calmer on the day itself. Our guide to how long the egg donation process takes shows where retrieval fits in the full timeline.

What happens during egg retrieval?

On the day, an anesthesiologist gives you anesthesia and monitors your breathing, heart rate and oxygen level throughout. Once you are asleep, the doctor completes the retrieval using ultrasound guidance, and the fluid from each follicle goes straight to the embryology lab, where embryologists find and count the eggs.

Where your retrieval takes place depends on your program. In the Fresh Matching Program, retrieval happens at the intended parents' fertility clinic. In the Frozen Egg Bank, retrieval takes place at our partner clinic in Southern California, and your eggs are vitrified (flash-frozen) soon after collection. Your case manager walks you through the location and schedule well before your retrieval date.

Is egg retrieval safe?

For healthy young donors, serious complications from egg retrieval are uncommon. A study of 4,052 retrievals in an oocyte donation program found complications related to the procedure in 0.42% of donors, most often internal bleeding, and no pelvic infections or anesthesia complications were seen in that series.² Across 7,098 IVF retrievals in another study, severe complications occurred in 0.08% of cycles.³

Possible risks include reactions to anesthesia, bleeding, infection and damage to nearby structures such as the bowel or bladder.¹ Ovarian hyperstimulation syndrome (OHSS), a reaction to the stimulation medications, is uncommon in egg donors, with moderate or severe OHSS reported in under 1% of donor cycles in a study of 4,052 egg donor cycles, which is why your care team monitors you closely before retrieval. Our article on egg donation side effects covers each one and when to call your clinic.

What happens after egg retrieval?

Most donors feel some cramping and bloating for about a week, and many are back to normal activity within a day or two. You will get clear instructions on what to watch for, and your case manager checks in with you afterward. For practical tips, read our guide to recovery after egg retrieval.

Your part of the cycle ends here. Donor Nexus pays your compensation by ACH or wire within 5 to 7 days of retrieval. Since 2012, Donor Nexus has supported more than 1,000 egg retrievals, and about 70% of cycles come from repeat donors and referrals.

Frequently asked questions

How long does the egg retrieval procedure take?

The procedure itself usually takes about 20 to 30 minutes. Plan on spending longer at the clinic for check-in, anesthesia and time in the recovery area before you go home.

Are you awake during egg retrieval?

No, egg retrieval is done under anesthesia, so you are asleep or deeply sedated and do not feel the procedure. An anesthesiologist monitors you the whole time.

How soon after the trigger shot is egg retrieval?

Egg retrieval is typically scheduled 32 to 36 hours after your trigger shot. The timing is precise, so take the shot exactly when your clinic tells you to.

Why do I have to remove nail polish before egg retrieval?

During the procedure a monitor is placed on your finger to measure your oxygen level. Nail polish and acrylics can interfere with that reading, so clinics ask you to remove them.

Can I go back to work after egg retrieval?

Most donors return to work or school the next day. Plan to rest on retrieval day and have someone take you home, because you cannot drive after anesthesia.
