Egg donation involves some discomfort at every stage, but most of it falls in the mild-to-moderate range. The process has three distinct phases that each feel different: weeks of hormone injections, the retrieval procedure itself, and a few days of recovery. The retrieval is the most intense part, though sedation keeps pain manageable for the majority of donors.
What the Hormone Injections Feel Like
Before your eggs can be collected, you’ll give yourself daily hormone injections for roughly three to four weeks. These medications stimulate your ovaries to develop multiple mature eggs at once instead of the usual one per cycle. The needles are small, typically going into the belly or upper thigh, and most donors describe the actual injection as a brief pinch or sting. Minor bruising at the injection sites is common.
The bigger source of discomfort during this phase isn’t the needles themselves but what the hormones do to your body. As your ovaries respond and enlarge, you can expect symptoms that feel a lot like an amplified version of PMS: bloating, abdominal cramping, breast tenderness, headaches, and fatigue. Some donors also notice mood swings, irritability, or skin breakouts from the hormonal shifts. These side effects build gradually as stimulation continues and tend to peak in the final days before retrieval.
Temporary weight gain is part of the package. Studies on ovarian stimulation show an average increase of about 5 pounds, mostly from fluid retention. In more pronounced cases, some patients have reported gaining 13 to 15 pounds during a cycle, though that weight drops off after the process ends.
Pain During the Retrieval Procedure
The egg retrieval itself is widely considered the most stressful and painful part of the entire process. It’s a short procedure, usually 15 to 30 minutes, where a doctor uses an ultrasound-guided needle inserted through the vaginal wall to reach each ovarian follicle and suction out the eggs.
You won’t be awake for it in the way you’d be awake at the dentist. Most clinics use conscious sedation or monitored anesthesia care, meaning you receive intravenous medications that make you deeply relaxed and drowsy while still breathing on your own. Some clinics use general anesthesia instead. Either way, the goal is to keep you comfortable enough that you feel little or nothing during the aspiration.
Even with sedation, some sensation gets through. A clinical trial that measured pain during retrieval on a 0-to-10 scale found that when clinics used a thinner needle, average pain scores landed around 4.3, with about 91% of patients reporting low to moderate discomfort. With the standard thicker needle, average scores rose to 6.3, and over 40% of patients reported severe pain (7 or higher). This means the specific equipment your clinic uses genuinely affects how much you feel. If pain management matters to you, it’s worth asking your clinic about their needle gauge and sedation protocol before you commit.
Recovery: The First Few Days
After retrieval, you’ll spend an hour or so in a recovery area as sedation wears off. Most clinics recommend taking the rest of the day off, and many donors return to normal activities within one to two days. The most common aftereffects are mild cramping, similar to period cramps, and light spotting or bleeding. Standard over-the-counter acetaminophen (Tylenol) is usually enough for pain relief during this window.
Bloating and a sense of pelvic fullness often linger longer than the cramping does. Your ovaries were enlarged to several times their normal size during stimulation, and they need time to shrink back down. For most donors, this residual bloating resolves within a week or two. Some donors, though, report not feeling fully recovered for longer, especially if they had a strong hormonal response. One donor surveyed after her second cycle described not feeling back to normal until months after the donation ended.
Ovarian Hyperstimulation Syndrome
The most significant pain risk in egg donation is ovarian hyperstimulation syndrome, or OHSS. This happens when the ovaries overreact to the stimulation medications and swell dramatically, leaking fluid into the abdomen. In a survey of 289 egg donors, about 39% reported moderate OHSS symptoms and 12% reported more severe cases. Only 13% experienced no symptoms at all, while 35% had mild symptoms considered a normal part of the body’s response to stimulation.
Mild OHSS feels like pronounced bloating and abdominal tenderness. Moderate cases bring more intense pain, nausea, and noticeable abdominal swelling. Severe OHSS, which is uncommon, can involve rapid weight gain, vomiting, and difficulty breathing, and it requires medical intervention. Your clinic will monitor you with blood work and ultrasounds throughout stimulation to catch warning signs early, and modern protocols have significantly reduced the rate of severe cases.
Emotional and Psychological Discomfort
Pain isn’t purely physical during this process. The hormone medications can cause real mood disruption. Donors commonly report feeling emotionally volatile, anxious, or unusually low during the stimulation phase. These feelings typically resolve once the hormones clear your system after retrieval, but they can be intense while they last, particularly if you’re someone who already experiences hormonal mood sensitivity.
There’s also the psychological weight of the process itself. Daily injections require discipline and can feel isolating, especially since many donors don’t tell friends or family. The combination of physical discomfort, hormonal mood shifts, and the time commitment (multiple clinic visits for monitoring over several weeks) adds up to an experience that’s more demanding than many donors initially expect.
What We Don’t Know About Long-Term Effects
One honest gap in the picture: researchers still don’t have solid data on the long-term health effects of egg donation. Despite over 30 years of practice, there are no large longitudinal studies tracking donors over decades. A major ongoing effort called the OVADO Project, based at UCSF, has been following nearly 500 egg donors from around the world since 2015, but results are still emerging. Without this data, it’s impossible to say definitively whether the hormonal stimulation carries any lasting reproductive or cancer-related risks. Anecdotal reports exist, but they haven’t been confirmed or ruled out by rigorous research.
For now, the known short-term pain and discomfort of egg donation is real but temporary for the vast majority of donors. The retrieval day is the hardest part physically, the hormone phase is the hardest part emotionally, and most donors are back to their baseline within a couple of weeks.
