Boys are more often born from artificial conception

For many women, the birth of a child is one of the most significant events in life. However, not all women can become pregnant naturally. In such cases, reproductive technologies such as artificial insemination can help realize the dream of motherhood.

Recent studies have shown that artificial insemination may have an impact on the sex ratio of newborns. Interestingly, using these technologies increases the likelihood of having a boy.

Scientists studied data on more than 13 thousand births to women who resorted to artificial insemination in clinics in Australia and New Zealand. All children were born after the transfer of a single embryo into the uterus.

According to the study, the sex ratio among babies born through artificial insemination was different from the sex ratio among babies born naturally. In the world, as a rule, 51% of births are boys and 49% are girls. However, in the case of birth through artificial insemination, the proportion of boys among newborns increased to 53-56%. When using the more complex and expensive ICSI technique (sperm injection into the egg), the proportion of boys among newborns, on the contrary, decreased to 48.7 - 50%.

So far, scientists have not been able to explain this pattern. However, they believe that patients at in vitro fertilization clinics should be informed about the connection between reproductive technologies and the sex ratio of newborns.

It is also worth noting that the success of artificial insemination may depend on the time of year in which the egg is collected. Studies have shown that eggs collected in the spring and summer offer a better chance of a successful pregnancy than eggs collected in the winter.

Thus, artificial insemination is an effective way to combat infertility, but it can also affect the sex ratio of newborns. Patients at assisted reproduction clinics should be informed of this pattern in order to make informed decisions.
