Reported per transfer, fresh donor eggs have historically led. CDC and SART national summaries across recent reporting years have shown fresh donor-egg transfers outperforming frozen donor-egg transfers on live-birth rate per transfer — a gap attributable to thaw attrition and to fresh cycles’ larger starting cohorts, which allow embryologists to select from more embryos. Two honest caveats: outcomes vary meaningfully by laboratory, and the frozen-egg gap has narrowed as vitrification technique matured. What has not changed is arithmetic: 20 fresh eggs make more embryos than 6 thawed ones, and more embryos mean more chances — this cycle and the next. Our SART-consistent outcome explainer is at donor egg success rates.
Because inventory economics require it. A bank retrieves one donor cohort and divides it among two to four purchasing families, which is precisely why your lot is small — and why “guarantee” programs exist to reassure buyers about a format with built-in attrition: expect roughly 90–95% of vitrified eggs to survive thaw at experienced labs, then normal fertilization and blastocyst attrition on what remains. Start with 6 eggs and the funnel can narrow to one or two transferable embryos. Start with a fresh cohort of 18 and the same funnel commonly leaves a family with several — enough for a second child years later from the same donor. The full arithmetic is at how many eggs per donor cycle.
An honest comparison names these plainly. Choose frozen when speed is paramount — banks ship in weeks, while fresh synchronization takes 2–4 months; when budget caps the journey at one embryo attempt and a lower upfront price matters more than cohort size; when a specific hard-to find donor exists only in a bank’s inventory or when clinic logistics rule out cycle synchronization. Frozen donation has built thousands of families. Our position isn’t that frozen fails — it’s that families deserve the yield math and per-transfer data before choosing, and banks rarely lead with either.
Now that both formats are priced, the comparison is arithmetic rather than argument.
A frozen lot of 6–8 eggs costs $18,000–$24,000 at Standard pricing or $24,000–$32,000 at Elite pricing, before approximately $20,000 in IVF medical costs — and before thaw attrition, since roughly 90–95% of vitrified eggs survive thaw at experienced laboratories.
A fresh cycle’s agency-side total of $36,900+ delivers the donor’s entire cohort, commonly 15–25+ eggs. At a 20- egg retrieval that is roughly $1,850 per egg — against $3,000–$4,000 per frozen egg, measured before any loss.
The gap widens across a whole journey. Surplus blastocysts from a fresh cohort freeze with high survival, so a second transfer — or a sibling years later — is a frozen embryo transfer at a fraction of a new cycle’s cost. Families who purchase a second frozen lot after an unsuccessful first attempt often pass the fresh figure without reaching a fresh cohort’s embryo count. Full line items at donor egg IVF cost; embryo math at how many eggs per donor cycle.
None of this makes frozen the wrong choice for every family — speed and a lower first invoice are real advantages, covered above. It makes the per-egg and per-journey math something families should see before deciding, which is precisely what inventory-based programs have little incentive to show them.
Ans. Fresh cycles offer larger cohorts, no egg-stage thaw loss, and historically higher per-transfer live-birth rates in national registry data; frozen offers speed and lower upfront cost.
Ans. Experienced laboratories commonly report roughly 90–95% survival — meaning some loss is expected in every lot.
Ans. Many programs counsel that a lot of 6–8 eggs offers a reasonable chance at one live birth, with no guarantee; fresh cohorts change that math substantially.
Ans. With fresh cycles, frequently yes — surplus embryos from one cohort are frozen for future transfers.

Egg donation is a process where a woman (the egg donor) provides one or several eggs (also known as oocytes) for purposes of assisted reproduction, with the eggs being fertilized in the laboratory. Once fertilized, the resulting embryos are transferred to the recipient’s uterus to initiate a pregnancy, or they can be cryopreserved (frozen) for future use.
