Is it true that with IVF more boys are born than girls?

Is it true that after the IVF proceduremore boys born than girls? Having asked this question, researchers from the University of New South Wales decided to conduct a series of experiments that would help to identify the ratio of male children to female. The research results can surprise even the most inveterate skeptic: some types of assisted reproductive technologies used to treat infertility really lead to the birth of more males than females.

IVF is born more than girls

How does IVF affect a child’s gender?

As you know, with natural conceptionPlanning the sex of the unborn baby can be completely useless. In order to outwit nature, Western parents often turn to clinics practicing sex determination “according to social indications”. In the Russian Federation, where you can only find out the sex of an already implanted embryo, the choice of the sex of the child is a criminal offense. Such a strict restriction is in order to prevent the development of discrimination on the basis of sex, because it often happens that parents prefer to have an infant of only a certain gender.

In vitro fertilizationambiguous technology, the benefits and harms of which are still debated even in the scientific community. Family planning specialists often warn their patients, who have lost hope of having a baby on their own, about the possible negative consequences of the procedure, however, the queues for doctors from this are not getting smaller. At the same time, the scandalously well-known methodology also had a positive quality: the desire of a future mother to give birth to a male child often comes true precisely after IVF. This was the conclusion of the research team that studied the effects of two different types of in vitro fertilization procedures: IVF and ICSI, in which donor sperm are injected directly into the egg.

ICSI - one of the methods of artificial insemination, in which a needle with a sperm is inserted directly into the egg

Analysis of the sex ratio showed that the proportion56.1% of male infants born as a result of IVF. At the same time, the probability of having a boy with ICSI is slightly less and is 50%, says sciencealert.com.

Although in some countries of the world legislation prohibitschoose the sex of the fetus during IVF, the results of the study prove that the choice of a certain artificial insemination procedure can really affect the gender of an unborn baby. Since at the individual level it turns out that the choice of the appropriate IVF or ICSI methodology is not chosen by the patients, but by the specialists of the clinic providing medical services, the results of the study should not be used as an actual tool for choosing sex.

Study Co-author, Professor Michael Chapman ofThe School of Women's and Children's Health also noted that, given that only 3.5 percent of children are born using assisted reproductive technologies, the social impact of the study will be negligible. In addition, the study provides an impetus for further study of the underlying causes that determine the survival of embryos of different sexes during pregnancy.
