Since the first pregnancy due to in vitro fertilization occurred in Spain 30 years ago, assisted reproduction techniques they have advanced notably, however experts point out that twin pregnancies have not been reduced.
Yes, the triplets and triplets pregnancies have been reduced, according to Dr. Pere Barri of the Quirón Dexeus University Hospital, but not the multiple pregnancies of two babies.
The news is usually well received by couples, it is not cause for dissatisfaction to know that two babies are expected, rather the opposite, but it cannot be denied that from the medical point of view it poses a risk to babies, who have more chances of being premature, and for mothers, who may have more complications in pregnancy and childbirth.
Achieving a decrease in the rate of twins is one of the great challenges of assisted reproduction, but multiple gestation is directly related to the number of embryos transferred to the uterus.
And if we think of a couple that has reached the point of having such an expensive treatment, with so many illusions deposited there, it is understandable that one chooses to assume the risks of transferring a single embryo that does not prosper and see the dream of becoming parents fade away.
According to Dr. Bari, humans are one of the species with the lowest fertility of nature, with a success rate during the first month of 20%, although there are couples that can reach 60%.
In vitro fertilization is the assisted reproduction technique that It has a higher success rate, 40 percent, followed by artificial insemination, 20 percent, and ovulation induction, 15 percent.
For his part, the expert has said that assisted reproduction, which does not lead to women more chances of getting cancer, has not managed to reduce the percentage of malformations in infants, since it presents data “identical” to natural reproduction, 2.2 percent.
