assisted reproduction

Nearly 50,000 treatments in 2021, with in vitro procedures reaching a record high

According to a medical study developed in Barcelona’s Hospital Clínic, fetuses conceived by assisted reproduction have changes in their heart and arteries, which begin even before birth and persist in the postnatal period. These changes represent a significant increase in cardiovascular risk in adulthood. However, the researchers point out that this situation is reversible from the beginning of life through a diet rich in omega3 and other factors. In addition, they strongly emphasised that this is only a risk factor and not a disease. The study leader, Eduard Gratacós, said that “it's a message of opportunity, not alarm”. Furthermore, they also recommend monitoring the blood pressure of these babies.

The exposure to music during in vitro fertilisation has a positive impact on the fecundity rate of egg cells according to a study developed by the assisted reproduction centre Institut Marquès, based in Barcelona. The study concludes that the micro vibrations in the music shake the culture liquid in which the ovum swims and this improves the distribution of nutrients and also avoids the accumulation of toxic products. As a result, the fertilisation of the ovum is facilitated and the success rate is improved by 4.8%. Three styles of music were tested (pop, heavy metal and classical) but no significant differences were observed in relation to the different frequencies.

Sant Joan de Déu Hospital in Greater Barcelona has become the first facility in the world to assist a woman who lost her two ovaries to get pregnant. A decade ago she had to have her ovaries completely removed because of two tumours. Ovarian tissue was frozen, kept for ten years and now re-implanted. The patient has had her period again and, thanks to in vitro fertilisation, is now pregnant.
