IVF clinic in San Francisco, CA. Live-birth success by patient age (own eggs, per intended egg retrieval) from the CDC's national ART registry (2021).
At Spring Fertility-San Francisco, reported live birth per intended egg retrieval with own eggs runs about 0.0% for patients under 35 — below the US national average of 46.0% for that age band, easing to about 0.0% by the >40 band. These are clinic-reported CDC figures and reflect the clinic's patient mix as much as its laboratory — a clinic that treats more older or complex patients will show a lower headline rate even with excellent care.
What this means in practice: a success rate is per attempt, not a guarantee. At an under-35 rate near 0.0%, roughly two egg retrievals are typically needed for a strong cumulative chance of a baby; at the older-age rate near 0.0%, many more — which is why cost per baby (cycle price multiplied by the cycles you are likely to need) is the honest figure to compare, not the headline percentage.
A US IVF cycle typically costs €15,000-25,000. Because own-egg success falls steeply with age, for patients over about 38 the cost per baby often favours donor-egg treatment in the EU, where live birth holds near 48% per transfer at any recipient age and a cycle costs €4,600-6,500 (Czechia, Greece, Spain).

This clinic's pattern: relatively stable performance across ages (0.0% under 35 to 0.0% by >40). Still, US cycle costs at €15,000–25,000 mean that for many patients over 40, EU donor eggs at ~48% per transfer and €4,600–6,500/cycle yield a lower cost per baby.

IVF success is driven mainly by maternal age and egg type, not by the country you choose. The public registries put own-egg live birth at roughly:
Spring Fertility-San Francisco in San Francisco, CA, under medical director Monica C. Pasternak, MD, reports live-birth outcomes to the CDC's National ART Surveillance System. The age-banded rates below are specific to this clinic's own-egg cycles, not national figures.
| Patient age | Spring Fertility-San Francisco | US national avg |
|---|---|---|
| 35-37 | 36.2% | 36.0% |
| 38-40 | 19.0% | 29.5% |
Spring Fertility-San Francisco — measured CDC profile: in patients 35-37 it reports 36.2% live births (0.2 pts above the US average of 36.0%); in patients 38-40 it reports 19.0% live births (10.5 pts below the US average of 29.5%). Across the 2 age bands with a national benchmark it lands above the US average in 1 (mean deviation -5.2 pts). Reported success falls roughly 48% from 35-37 to 38-40 at this clinic — the steep age gradient common to every US programme, set by egg biology rather than the lab. Figures are clinic-reported live births per intended egg retrieval (own eggs) and reflect each clinic's patient mix.
