If your egg retrieval is coming up and your primary source of information so far has been a one-page handout from your clinic and a series of increasingly panicky Google searches, you are not alone. Egg retrieval is one of the most physically significant steps in IVF and egg freezing, and yet the amount of detail most patients receive beforehand could fit on an index card. You deserve better than that.
This article is meant to serve as a thorough walkthrough of what happens before, during, and after an egg retrieval, including the practical details that rarely make it into the clinical brochures: what to wear, how sedation actually feels, what "normal" recovery looks like versus what warrants a call to your doctor, and why the hours after the procedure can feel emotionally bigger than you expected.
Before the Procedure: The Trigger Shot and Prep
The countdown to egg retrieval begins with the trigger shot, typically administered exactly 36 hours before your scheduled procedure. According to Cofertility's trigger shot guide, this injection (usually hCG or a GnRH agonist like Lupron) signals your follicles to complete the final stage of egg maturation. The timing is precise because your doctor needs the eggs to be mature but not yet released. If the trigger is given too early or too late, it can affect how many mature eggs are retrieved.
One thing that catches people off guard: an hCG trigger shot can cause a false positive on a home pregnancy test for 10 to 12 days afterward. This is not a sign of anything. It is the medication leaving your system. If you are someone who tests frequently, it helps to know this in advance.
The night before and morning of your retrieval, you will need to fast. The NHS (Guy's and St Thomas') advises at least seven hours without food or drink before the procedure, since you will be receiving sedation. Your clinic will also typically ask you to arrive without perfume, nail polish, or contact lenses, and to wear loose, comfortable clothing you can change out of easily. Fertility Institute of New Orleans recommends elastic waistbands and layers, since you will likely be bloated afterward and want clothing that does not press on your abdomen. Leave jewelry at home. Bring a book, headphones, warm socks, and your support person.
During the Procedure: What Actually Happens in the Room
Egg retrieval is a transvaginal ultrasound-guided procedure performed in a clinic's procedure room, not a hospital operating room. The Mayo Clinic describes it as an outpatient procedure that typically takes 10 to 30 minutes, though most retrievals are closer to 15 to 20 minutes once everything is underway.
You will change into a gown and be positioned on a procedure table, similar to the setup for a regular transvaginal ultrasound. An IV line is placed, and sedation begins. According to a comprehensive review in PMC, approximately 99% of egg retrievals use intravenous conscious sedation, most commonly a combination of propofol with fentanyl or midazolam. You are not under general anesthesia in the traditional sense; you are in a deep twilight state where you are breathing on your own but unlikely to feel pain or remember the procedure. Some patients recall fragments; most remember nothing from the moment the sedation takes effect until they wake up in recovery.
Once you are sedated, your doctor inserts an ultrasound probe with a thin needle guide attached. The needle passes through the vaginal wall into each ovarian follicle (the fluid-filled sacs that contain the eggs). Using gentle suction at body temperature, the fluid from each follicle is aspirated into test tubes, which are immediately handed to an embryologist in an adjacent lab. The embryologist examines the fluid under a microscope to identify and isolate each egg. You will not feel the needle, but some patients report a vague sense of pressure if the sedation is lighter.
The number of follicles determines how long the procedure takes. Someone with 8 follicles will have a shorter retrieval than someone with 25. Your doctor works through one ovary, then the other, aiming to drain every accessible follicle.
Waking Up and the First Few Hours
After the procedure, you are moved to a recovery area. The Cleveland Clinic notes that most patients wake up within 10 to 15 minutes and spend one to two hours in recovery before being discharged. During this time, nurses monitor your vitals, and you may be offered crackers and water. Some people feel groggy, mildly nauseous, or emotionally raw from the sedation. All of this is normal.
You will not be allowed to drive yourself home. Most clinics require a support person to be present, and you should plan to rest for the remainder of the day. Light vaginal spotting or blood-tinged discharge is common and typically resolves within a day or two.
And then there is the call. At some point, usually within a few hours, your clinic will tell you how many eggs were retrieved, how many were mature, and (if applicable) how many fertilized normally. If you have been on the fertility forums, you know this call carries enormous emotional weight. The number you hear may or may not match the number of follicles your doctor saw on monitoring ultrasounds. Not every follicle contains a mature egg, and not every egg will fertilize. This is biology, not a referendum on you.
The Days After: What Recovery Actually Looks Like
Most patients feel well enough to return to normal activities within 24 to 48 hours, though some describe lingering soreness, bloating, or fatigue for up to a week. According to Spring Fertility, bloating typically peaks in the first few days and resolves within five to seven days. Some patients notice water weight gain of up to five pounds, which is temporary and related to fluid shifts from ovarian stimulation.
A Cochrane review on pain management found that about 3% of patients experience severe pain after retrieval, and about 2% have pain lasting more than two days. For the majority, over-the-counter pain relief and rest are sufficient. Your clinic will likely recommend avoiding NSAIDs (like ibuprofen) and suggest acetaminophen instead, along with a heating pad and plenty of fluids.
Your first period after retrieval usually arrives within 10 to 14 days and may be heavier or more uncomfortable than usual. Many patients describe this period as the point at which they finally feel "back to normal" physically.
When Something Does Not Feel Right
Egg retrieval is a low-risk procedure, but it is not a zero-risk one. According to a comprehensive review of complications in PubMed, the overall complication rate ranges from 0.3 to 3%. Vaginal bleeding occurs in 0.5 to 8.6% of cases (most of which resolves on its own), pelvic infection in 0.01 to 0.6%, and ovarian torsion in 0.08 to 0.13%.
Ovarian hyperstimulation syndrome (OHSS) is the complication patients hear about most. The Mayo Clinic estimates it occurs in 3 to 6 out of every 100 IVF cycles, with symptoms ranging from mild bloating and discomfort to (in rare severe cases) difficulty breathing, rapid weight gain, and decreased urination. Mild OHSS typically resolves within 7 to 14 days; severe OHSS requires medical attention.
Call your clinic if you experience sharp or worsening abdominal pain, a fever above 101°F, heavy bleeding (soaking a pad in under an hour), vomiting you cannot keep down, significant difficulty urinating, or rapid abdominal swelling with shortness of breath. These are not normal post-retrieval symptoms, and your clinic wants to hear from you.
What Might Help You Feel More Prepared
Ask your clinic for their specific pre-op checklist. Fasting windows, medication instructions, and arrival times vary between clinics. Get it in writing.
Plan for a full rest day afterward. Even if you feel fine, your body just went through a lot. Give it a day. Stock your fridge the night before with easy meals, electrolyte drinks, and high-sodium snacks (salt helps with bloating recovery).
Manage expectations around egg numbers. The number retrieved is not the number that will fertilize, and neither is the number that will make it to day five. This is a funnel, not a guarantee, and every step is normal even when the numbers drop.
Have your support plan in place. A ride home is required. Emotional support in the days after is equally important, especially while waiting for lab updates. Let someone know what you are going through.
Write down your questions before your pre-op appointment. Ask about anesthesia type, expected follicle count, bloating timeline, and when to call versus when to wait. Your clinic answers these questions every day. You are not being difficult for asking.
Egg retrieval is quick, but it is not small. It is a real medical procedure, and the anticipation around it is usually bigger than the procedure itself. Knowing what to expect does not make the experience easy, but it can make it feel a little less like something that is happening to you and more like something you walked into with your eyes open.
