Multiple pregnancies by in vitro fertilization
The fertilization in vitro, it has a margin of effectiveness that is around 65% of couples or single people, managing to position itself in one of the most common practices among the population with some type of infertility. However, the question may arise: Is there a possibility of having a multiple pregnancy, even if it is not planned?
One out of every five couples presents infertility in some period of their life; the majority with less tedious treatments manage to gestate without major complications, while the remaining group must look for alternatives to live the experience that being parents offers them.
In vitro fertilization seeks to obtain success rates in all patients who approach the technique, and for this each phase that is performed comes with a certain number of samples, which are directed to the laboratory in search of a more in-depth analysis. Their compatibility between genetic material, possible risks, or in some cases, it is concluded that oocytes or sperm cannot be used in IVF is determined. For these cases, it is also possible to go to a third party donation. Everything will depend on the situation of the couple or interested person.
However, those samples that are sent to the laboratory tend to collect 3 or more oocytes and a considerable number of sperm.
During ovarian stimulation, unlike a woman's menstrual cycle, 3 or more oocytes are collected and studied. A part is sent to the fertilization process with the sperm, and the rest are frozen, if the couple wishes. It is also at your discretion and choice, to donate them to the chosen medical center.
The mature oocytes that are fertilized, are two or more, because it gives a greater possibility of success in case one of them fails or fertilization is not achieved in any of them. This occurs in one of the last phases of the treatment, where the implantation of the embryos in the woman's uterus begins.
Doctors implant between two or a maximum of three embryos for fear that if it is only carried out with one embryo, the chances of success are reduced to a low probability, since they are not acclimatized and there is a risk of having to start the process from the initial stage. The IVF technique continues to improve the way in which the effectiveness of pregnancy with an embryo is studied, since these are caused in sporadic cases, a twin pregnancy, even if it is not planned by the couple.
Multiple pregnancies have a 20% – 22% rate of manifesting.And limiting embryo transfer to just two produces an 18% chance of success. It is not common for it to occur, but it is an existing possibility that parents should take into account.
In the case of a triplet pregnancy, the probability is even lower, and is generally due to the implantation of more than three embryos due to the low effectiveness of the uterus or another medical reason that is detailed to each patient.
Medicine continues to work on improving these processes, and when the couple goes to a center specialized in IVF techniques, it is important to leave all doubts on the table and clarify the issues that on the internet can generate feelings of panic or uncertainty. Another tip is to visit pages endorsed by medical centers or surrogacy agencies.
