Children after IVF
For many years infertility has been considered an unsolvable problem for many couples who faced such a diagnosis. Today, due to development of reproductive technologies the in vitro fertilization has become a relief to thousands of families.
However, despite the fact that IVF helps kiddies to be born, the debate as to what these little ones are born like, is going on. They arouse interest not only in parents who decided to carry out the procedure, but also in doctors and even in psychologists. Despite the fact that with IVF the interference occurs only at the moment of conception, and not throughout the prenatal development of a baby, many of them claim that these children face a too great risk of various pathologies.
What does the science say?
More than 35 years have passed since the birth of the first child conceived via in vitro fertilization. And during these years lots of studies on the health of babies born after its application have been carried out. According to the data obtained it was reported that IVF has no negative impact on the child's health. That is, the increased risk of cancer, deafness and other congenital abnormalities - all the fears which many people have experienced do not have a real basis. Development of any fetal abnormalities in children born after in vitro fertilization occurs not more frequently than in cases where pregnancy occurs naturally. It is not the way of conception but heredity, the gene pool and even individual features of each woman that influence a probability of their occurrence.
Tried with time
In addition to proven scientific facts about the "normality" of children born after in vitro fertilization, it is necessary to take into account the fact that this method of conception is already showing actual results "in reality". For more than 30 years many children were born after IVF, and judging by their medical records, they are no different from the common "natural" children. Moreover, some of the children born after IVF have reached the childbearing age and have proved the falsity of the opinion that infertile couples can give birth only to infertile children - many people conceived "in vitro" have their own children.
Benefit of IVF
It is believed that the in vitro fertilization method does not harm the health of the future children, but can also influence it positively. This opinion is based on the fact that embryologists carefully treat the seminal fluid before the fertilization and choose the healthiest and most viable sperm cells. Also, only the healthiest and the "strongest" embryos from all successful ones are taken for transferring to the uterus.
It is also possible to avoid certain genetic diseases by using donor sperm for fertilization instead of the biological material of a spouse, and the technique of pre-implantation genetic diagnosis allows transferring only genetically normal embryos to the uterus.
Another important advantage of this view is the fact that in the case of IVF there is a possibility of pre-determining the child's sex. And, despite the fact that in some countries this service is not allowed, in some cases it is necessary for the birth of a healthy baby. For example, if parents have genetic diseases transmitted only across the male line.
Do children after IVF get sick more often?
Another myth associated with children born after in vitro fertilization - sickliness of such kids. But the fact that these kids get sick more often, actually, has not been identified and remains just a rumour associated with this procedure.
Risks during IVF
Surely, there are some risks associated with this type of fertilization. For example, multiple pregnancy, which occurs after in vitro fertilization more often than in the case of natural conception. This pregnancy is somewhat more complicated, since the load on the woman's body is significantly increased. In addition, in such pregnancies preeclampsia (gestational toxicosis), anemia, toxicosis and other unpleasant symptoms that do not have any positive effect on the fetus, occur more often. Also, multiple pregnancy is much more likely to result in a preterm delivery than in the case of gestation of a single child, due to the heavy load on a woman's body.
But it should be borne in mind that all these complications may arise with a multiple pregnancy that occurred naturally. The only difference is that this happens much more frequently in IVF pregnancies.
Therefore, to avoid the risk of a successful implantation of all the embryos, today the number of the transferred ones has been reduced to two. And in some cases, when multiple pregnancy is contraindicated for a woman due to certain individual characteristics, only one embryo is transferred into the womb. This became possible thanks to improvement of work of the embryologists and increase of effectiveness of IVF.
Summarizing the aforesaid, we can conclude that there is no difference between IVF children and usual babies, apart from the method of conception.
