Egg Donation Risks and Side Effects

If you’re thinking about becoming an egg donor, it’s natural to have questions—especially about risks and side effects. Transparency matters. While complications from egg donation are rare, it’s important to understand what’s possible so you can make a fully informed decision. 

At Fairfax EggBank, donor safety is our top priority. As one of the largest and most experienced egg banks in the world, we use evidence-based protocols, careful monitoring, and personalized support to reduce risks wherever possible. 

Egg retrieval is a 15–20-minute outpatient procedure that takes place at one of our partner fertility clinics. Most donors resume normal activity the next day with minimal to no side effects. 

Still, egg donation and retrieval are medical procedures, and every medical procedure carries some level of risk. Below, we’ve outlined the most common egg donation risks and side effects, along with how we work to prevent them.  

What are the Risks of Egg Donation?

Ovarian Hyperstimulation Syndrome (OHSS)

OHSS happens when excess fluid from the ovaries transfers into the abdominal cavity causing moderate to severe bloating. In mild to moderate cases of OHSS, the fluid is slowly reabsorbed over the course of several days.  

  • How we reduce risk: We may adjust your medication dose or use a different medication (like a “trigger” shot alternative) to reduce or prevent this response.
  • How common is OHSS: About 1–3% of donors may experience OHSS.

Ovarian Torsion

This rare complication occurs when an ovary twists on itself, causing sudden pain. 

  • How common: Less than 0.3% of cases.
  • Prevention: You’ll be asked to pause high-impact activities like running, horseback riding, or heavy lifting during the cycle to lower the risk.

Infection

There’s a small chance of infection after the egg retrieval. 

  • How common: Less than 1%.
  • Prevention: You’ll receive a preventive antibiotic—either orally or through an IV during the procedure.

Pregnancy

Because fertility medications increase the number of mature eggs, unprotected sex at any point in the cycle can lead to pregnancy—even after retrieval. 

  • How to prevent it: We ask donors to abstain from sex during the entire cycle. If you are sexually active at other times, it’s essential to use reliable protection.

Side Effects of Egg Donation

During Hormonal Stimulation

During the stimulation, some donors feel little to no difference. Others experience symptoms like: 

  • Bloating
  • Breast tenderness
  • Headaches or mood swings

These are related to the temporary rise in estrogen from your developing follicles—similar to premenstrual syndrome or PMS. 

After Egg Retrieval

The retrieval itself is a brief (15–20 minute) outpatient procedure done under light anesthesia. Most donors recover quickly and resume normal activity within a day. 
You might feel: 

  • Cramping (similar to period cramps)
  • Mild bloating or spotting
  • Grogginess or nausea after anesthesia

Most discomfort is manageable with over-the-counter pain relief like Tylenol.

Egg Donation Risks FAQs

Does Egg Donation Cause Cancer?

Nope! According to American Society for Reproductive Medicine, ASRM, there is no data that show any link between egg donation and cancer. Learn more here

Does Egg Donation Affect My Future Fertility?

There are no conclusive studies indicating that egg donors are at an increased risk for experiencing infertility issues. Plenty of our donors go on to become mothers or have more children after they donate. Learn more here. 

Will Donating Eggs Deplete My Own Egg Supply Quicker?

No. Your body naturally matures 15–20 eggs each cycle, but usually only one ovulates. The rest are reabsorbed.  

Fertility medications help mature more of those eggs already recruited for that month—they don’t “use up” future eggs. We can only retrieve what your body has selected for that cycle. Learn more here.
