European pregnancy rates

We present the pregnancy rates following IVF in European countries in 2005. The results were collated from the European IVF Monitoring Programme, EIM) that operates under the European Society of Human Reproduction and Embryology (ESHRE). The results were published in Human Reproduction, official journal of ESHRE (EIM, A.N.Andersen et al., Hum Reprod. 2009 Feb;24(6):1267-1287, 2009).

This is the seventh annual report of ESHRE, while the six previous ones concern statistical data form the years 1997-2002. The data for 2005 were collected from 30 European countries. The quality of data differs from country to country and is not always complete.

For Greece, the data are derived from 12 IVF Units from a total of 50 and are collated by the Prof. Basil Tarlatzis, Professor of Obstetrics-Gynaecology and Human Reproduction at Aristotle University of Thessaloniki.

Eugonia (with its present scientific composition) has participated fully in this annual registration of data since 1997.

We present three tables summarizing clinical pregnancies and live births rates resulting from IVF (Table 1), ICSI (Table 2) and cryopreserved embryos (Table 3).

For IVF, the average clinical pregnancy rate is 30.3% per embryo transfer, ranging from 20.00% to 50,00% between different countries.

Table 1: Clinical pregnancy and live birth rates following IVF in 2005

Note: Pregnancy rates of European countries are calculated over the total of treated women without age classification.

ICSI = intracytoplasmic sperm injection
E.T = embryo transfer
Pregnacies = Clinical pregnancies

In the case of transfer of frozen embryos (FER) the average clinical pregnancy rate is 30,9% per embryo transfer, ranging from 20,00% to 41,7% between different countries.

Table 2: Clinical pregnancy and live birth rates following ICSI in 2005

Note: Pregnancy rates of European countries are calculated over the total of treated women without age classification.

FER = frozen embryo transfers
E.T = embryo transfer
Pregnacies = Clinical pregnancies

In the case of transfer of frozen embryos (FER) the average clinical pregnancy rate is 19,6% per embryo transfer, ranging from 11,8% to 30.0% between different countries.
