🧬 What Egg Retrieval Is Actually Like: A Minute-by-Minute Walkthrough

Egg retrieval — formally called transvaginal oocyte pick-up (OPU) — is the moment most IVF patients dread before doing it and are pleasantly surprised by afterward. The procedure itself is short, you are asleep for it, and most patients are back home within a few hours. This walkthrough takes you through the day as it actually unfolds.

The Night Before: The Trigger Shot

Approximately 35 to 36 hours before your scheduled retrieval, you give yourself the trigger shot — usually hCG (such as Ovidrel or Pregnyl) or a GnRH agonist trigger (Lupron), depending on your protocol. Timing is critical. If you trigger at 9:00 PM, your retrieval will be scheduled around 8:00 to 9:00 AM two mornings later. Set multiple alarms. Have your partner double-check the dose with you.

You stop all other stimulation injections after the trigger. The trigger does the final job of maturing the eggs inside the follicles so they can be retrieved.

Eight Hours Before: Fasting

Because you will be sedated, you cannot eat or drink anything (including water) starting roughly 8 hours before your procedure. Confirm fasting rules with your clinic. Some clinics allow small sips of water up to 2 hours prior under modern anesthesia guidelines, but follow your specific clinic instructions exactly.

Morning Of: Arrival

You will be asked to arrive 60 to 90 minutes before your scheduled procedure time. Wear loose, comfortable clothing. Bring your partner or a support person, who will need to drive you home — you cannot drive after sedation. Leave jewelry, contact lenses, and makeup at home.

At check-in, expect to confirm your name, date of birth, and the planned procedure several times. This is intentional — these checks prevent procedural errors.

Pre-Procedure Setup (T-minus 60 to 30 minutes)

You will change into a hospital gown. A nurse will start an IV line in your hand or arm. Your vitals (blood pressure, heart rate, oxygen) will be monitored. The anesthesiologist will meet with you to review your medical history, allergies, and consent for sedation.

If you are having ICSI or freezing all embryos, your partner (or sperm donor process) will produce a sperm sample around this time. For frozen sperm or donor sperm, the lab thaws and prepares it.

Wheeled into the Procedure Room (T-minus 15 minutes)

You are wheeled (or walk) into the procedure room. It looks like a cross between an exam room and a small operating theater. You will see an ultrasound machine, a procedure chair similar to an ob/gyn exam chair, and a window or hatch connecting to the IVF lab next door — that is where your eggs will go immediately after retrieval.

You will be positioned in stirrups, similar to a pelvic exam.

Going to Sleep (T-minus 5 minutes)

The anesthesiologist administers IV sedation — typically propofol, sometimes combined with fentanyl. This is monitored anesthesia care (MAC), not general anesthesia. You will not need a breathing tube. You feel a cool sensation in your arm, count backward from 10, and almost always wake up before you finish.

The Procedure (10 to 30 minutes)

With you asleep, the RE performs a transvaginal ultrasound to visualize each ovary. A long, thin needle is guided through the upper vaginal wall into each follicle. The follicular fluid (containing the egg, hopefully) is aspirated through the needle into a test tube and immediately handed through the hatch to the embryologist next door, who examines the fluid under a microscope to find and isolate the egg.

Each follicle is aspirated in turn. The total procedure time depends on follicle count — typically 10 minutes for a low-response cycle, up to 30 minutes for a high-response cycle with 20+ follicles.

You feel none of this.

Waking Up (T-plus 5 to 15 minutes)

You will wake up in a recovery area, often called the PACU (post-anesthesia care unit). You will feel groggy. You may have mild to moderate cramping similar to period cramps. Some patients have light vaginal spotting. A nurse will offer pain medication, water, and crackers.

The RE or embryologist will come by to tell you how many eggs were retrieved. This is the number of follicles aspirated that contained an egg — not all will be mature, but the total egg count is what you will hear first.

Going Home (T-plus 1 to 2 hours)

Once you are stable, can drink fluids, urinate, and walk steadily, you are discharged. Your support person drives you home. Plan to rest for the remainder of the day. Most patients feel well enough to return to light work the next day.

What Recovery Actually Feels Like

For 24 to 48 hours expect: mild cramping (manageable with acetaminophen — confirm with your clinic about NSAIDs), bloating, light spotting, and fatigue. Significant pain, fever, heavy bleeding, severe bloating, or shortness of breath are warning signs of complications such as OHSS (ovarian hyperstimulation syndrome) or bleeding and require an immediate call to your clinic.

The Fertilization Update

The day after retrieval (day 1), the lab will call to report fertilization results — how many of the mature eggs successfully fertilized. This is one of the most emotional calls of the cycle. Try to be in a place where you can absorb the news.

Practical Tips

Lay out comfortable clothes the night before. Pack a heating pad and a water bottle for the ride home. Have soft food ready. Cancel non-essential meetings for 24 hours. Have your phone charged for the fertilization call.
