A common misconception among fertility patients is that “fewer eggs but better quality” represents an ideal outcome. Research increasingly demonstrates the opposite: when it comes to IVF, more eggs generally translate to better chances of success.
Addressing the “Quality vs. Quantity” Myth
When retrieval yields exceed 20–25 eggs, pregnancy rates can sometimes appear lower — but this is likely due to endometrial hyperstimulation rather than compromised egg quality. The solution is a “freeze-all strategy” that postpones embryo transfer to allow the uterus adequate preparation, which has demonstrably improved success rates.
Our egg donor program research revealed that donors producing more eggs correlated with higher pregnancy rates among recipients. This evidence suggests that egg quantity does not inherently diminish quality.
The Evidence Behind More Eggs
The greater the number of eggs, the greater the chance of getting a pregnancy — and this is independent of the woman’s age.
While overstimulation should be avoided due to serious health risks, obtaining more eggs through controlled stimulation remains beneficial for IVF candidates, those accumulating oocytes for egg freezing, and those pursuing treatment at advanced ages.
When Fewer Eggs Might Be Appropriate
There are rare scenarios where minimal retrieval might be the right strategy — these warrant individual discussion with your fertility specialist, who can weigh your specific clinical situation, age, and treatment goals before recommending a protocol.
