Your clinic said the serious OHSS risk is about 1-2%.
Researcher Diane Tober's donor surveys found rates closer to 10%.
Someone is off by a lot.
Here are eight things hiding inside that gap.
1. "Mild Discomfort" Is Doing a Lot of Heavy Lifting
Clinics use "mild discomfort" the way restaurants use "cozy" to describe cramped tables.
Donors repeatedly describe days of extreme abdominal pain and feeling "bruised from the inside."
That's not mild.
That's a euphemism wearing a lab coat.

2. The Stats Come From Clinics With Reasons to Look Good
Reported OHSS rates come largely from clinic-reported data.
Clinics track what gets documented.
They document what walks back through their door.
Mild-to-moderate cases handled at home? Often never counted.
That 1-2% figure reflects reported cases, not experienced ones.

3. Donors Don't Ask the Questions That Would Surface the Risk
One nurse-donor admitted she arrived with 10 questions and asked only 3.
She was too scared to ask the rest.
A nurse, with medical training, still intimidated in a clinical setting.
If that's the baseline, most donors are walking out far less informed than they need to be.

4. High Egg Yields Get Celebrated, Not Questioned
Some donors retrieve 30+ eggs in a single cycle.
Clinics often frame this as a great outcome.
But extraordinarily high yields are a known OHSS risk factor.
A donor who produced 36 eggs in one cycle later wondered if her body was pushed past safe limits.
That question deserves a real answer before retrieval, not after.

5. PCOS Is Flagged as Disqualifying, Not Discussed
Women with PCOS are frequently turned away before they ask a single question.
The concern isn't arbitrary.
PCOS does elevate OHSS risk.
But blanket disqualification ignores individual hormone profiles and ovarian reserve specifics.
It also quietly removes a population whose experiences could tell us a lot about where the real risk ceiling sits.

6. Long-Term Follow-Up Is Essentially Nonexistent
Once retrieval is complete, most donors are medically on their own.
No longitudinal monitoring.
No systematic follow-up calls six months later.
The most widely cited reassurance stats come from small, older samples.
According to Tober's research, donor voices and long-term health data remain a serious gap in the fertility industry.
If complications develop quietly over years, they don't show up in the clinic's published rate.

7. Consent Forms Aren't the Same as Understanding
Donors sign detailed forms.
That part is documented carefully.
But signing a form in a fast-paced appointment isn't the same as genuinely understanding alternatives and risk gradients.
A 21-year-old with student debt, sitting across from a confident medical team, is not operating from a level playing field.
Informed consent is only as good as the conditions surrounding it.

8. The Stories That Get Shared Skew the Perception in Both Directions
Negative experiences generate more online engagement than unremarkable recoveries.
Reddit threads and TikTok videos about extreme OHSS get thousands of views.
But the flip side is also true.
Clinics highlight smooth experiences in their materials.
Neither extreme is the full picture.
The real OHSS story lives somewhere in between, in the data nobody is systematically collecting from donors themselves.
That gap between 1-2% and 10% isn't just a statistical discrepancy.
It's what happens when the people experiencing something aren't the ones defining it.
If you're a healthy woman between 21 and 32 who wants real information before making this decision, programs like MyEggBank offer comprehensive medical screening and direct support throughout the process.
Donors can earn between $10,000 and $20,000 per cycle, with up to $90,000 available across six cycles.
Going in informed changes everything.
