Spain, at the forefront of assisted reproductive treatment in Europe
With 156,865 cycles in one year. These are the findings from a statistical report presented last Tuesday at the Ministry of Health, including data from nearly 300 centres around Spain.

This November, a report on 2014 data from the National Registry of activity and results of assisted reproductive treatments in Spain was presented to the Ministry of Health, Social Service and Equality. This registry collects data from 278 centres that offer fertility treatment in Spain. The figures in terms of activity, totalling 156,865 reproduction cycles, place Spain in the lead for assisted reproductive treatments in Europe. Of these centres, 225 perform In Vitro Fertilisation and 272 perform Artificial Insemination, though many carry out both techniques.

The document reports on a total of 156,865 reproduction cycles carried out in 2014.

The Spanish Fertility Society, the body responsible for managing the Registry of the Ministry of Health, Social Service and Equality over recent years, and thus funded by this Ministry, considers this report the first record of assisted reproductive techniques to offer overall data on the number and quality of treatments in addition to other points of interest, such as the number of births, patient ages and the percentage of multiple pregnancies.

The document reports on a total of 156,865 reproduction cycles carried out in 2014, 116,688 of which were In Vitro Fertilisation (IVF) and 40,177 of which were Artificial Insemination (AI).


The number of registered births thanks to the reproductive techniques recorded in the report reached 28,669 that year. A total of 33,934 new-borns resulted from those births, while the rate of multiple births has continued to decrease over recent years, currently standing at 20.4%. The Single Embryo Transfer (SET) is an objective for the scientific community, meaning that research in the field of fertility in recent years has been proposing methods for embryo selection in order to improve implantation rates and thus move away from the two-embryo transfer.

Researchers are working to make assisted reproduction as similar as possible to natural reproduction. As a result, the lowest-ever figures for multiple births in the history of reproduction in Spain were achieved in 2014. That year, 85,626 embryos were transferred in 47,425 fertilised embryo transfers using both donor eggs and recipients’ own eggs, averaging 1.8 embryos per transfer.


47% of IVF cycles, regardless of whether donor eggs or the recipients’ own eggs were used, were performed on patients between 35 and 39 years of age, the most highly represented age group. However, 68% of IVF egg donation cycles were carried out on patients over 40 years of age.

Artificial Insemination is a technique which requires high quality eggs in order for a pregnancy to be achieved, as fertilisation takes place naturally –inside the woman’s uterus– with the only help being the introduction of a semen sample into the vagina using a cannula. 93.5% of the patients who underwent this type of cycle were under the age of 40, while 6.5% (2,627 inseminations) were over the age of 40.
