Victoria Anna, the first 'test tube baby' born by in vitro fertilization in Spain, turns 35 this Friday, in which the methods of assisted reproduction have evolved so much that now a third of the artificial fertilizations are made with donor eggs.
The scientific parents of Victoria Anna, who weighed 2,470 kilos at birth and was the fourth baby born in Europe by in vitro fertilization and the sixth worldwide, were gynecologist Pedro N. Barri, biologist Anna Veiga and a team of specialists from the then Dexeus clinic, currently Dexeus Woman.
Barri recalled today that "Victoria Anna was born at nightfall and labor began spontaneously at 37 weeks of gestation."
The biological parents of Victoria Anna are a couple from Badalona (Barcelona), in which she had a problem of obstruction in the fallopian tubes that made pregnancy difficult.
"But once she became pregnant, the evolution of the pregnancy was completely normal, although we did exhaustive controls every three days," recalled Barri, who pointed out that in vitro fertilization is now a common practice with which they were born more than 8 million children around the world.
According to the Spanish Fertility Society (SEF), 8% of all children born today do so with the help of assisted reproduction.
Barri has highlighted that in 35 years many things have changed in assisted reproduction, for example, the average age of women who turn to it, which has gone from 35 to 39 years, "and, in our center, 50% already over 40 years old ".
The techniques have also evolved a lot, which now allow, for example, that 35.7% of in vitro fertilization cycles be done with preimplantation genetic tests of aneuploidies (PGD) to rule out chromosomal alterations in the embryo, due to the ages advanced women.
According to Dexeus Mujer, 22% of in vitro fertilization are cycles of delayed transfer, with previously frozen embryos, and more than 30% require donor eggs.
Barri stressed that the birth of Victoria Anna "was a milestone for science and opened a door to hope for many women and families with fertility problems.In Spain, in addition, marked a before and after, as it was the step definitive to boost the advance and development of the medicine of the reproduction ".
"When we started, most of the treated women were married or lived as a couple, while currently the majority profile of assisted reproduction patients are elderly women, as well as single women or without a male partner and homosexuals who resort to fertilization In vitro to create a family, which has given way to new models very different from the traditional concept, "added Veiga.
The biologist has reminded us that multiple pregnancies and premature births were the biggest risks in 1984, and now they have been reduced very significantly, since specialists get in most cases to transfer a single embryo.
According to the latest data from the SEF, corresponding to the year 2016, 17% of pregnancies by in vitro fertilization with own ovules, and 20% of pregnancies with donor eggs were twinned.
Dexeus specialists have stressed that Spanish legislation, in addition, is much less restrictive than in other countries and allows the preservation for social reasons and the donation of ovules anonymously, which has also favored the so-called 'tourism' reproductive.
