Worldwide Data
The World Egg and Sperm Bank takes great pride in accurately collecting and reporting precise pregnancy outcome data for intended parents and the clinics who serve them. We do not cherry pick data from specific time frames, clinics, or countries to boost “success” results. In fact, our data are carefully averaged from ALL the gametes The World Egg and Sperm Bank provides to ALL clinics worldwide:
- Egg Survival: 92.1%
- Worldwide Clinical Pregnancy Per Ova Thawing: 58.2%
Our pregnancy rate is ONLY derived from the first transfer from a single cohort. This is unlike other banks that may mix cumulative pregnancy rates from multiple treatments. Hence, they may say a 60% – 80% pregnancy rate but that may be after 2 or more transfers of embryos from a single or multiple cohorts of an unknown number of eggs. This number is misleading and does not reflect your potential for pregnancy after the first transfer with a single cohort of eggs.
Also our pregnancy rate is a CLINICAL pregnancy rate defined by a sac (not a single positive HCG blood test).
- Embryos Transferred To Each Patient: 1.18
- Transferable Or Freezable Embryos For Each Cohort Of 6 Eggs: 2.78
