The information, published in the Australian Daily on September 29, indicates that IVF may increase the chances of having a son by 56.1% compared to other conventional treatments, only about 48.7%. .
The group of scientists at the University of New South Wales also pointed out differences in influence on society and individual couples.
Accordingly, the growing number of couples who tend to choose sex increases, a problem that is considered " illegal " in Australia, which is opposed to the problems of population disparities in society.
The study analyzed 13,368 children born with medical intervention from 2002-2006, which showed different effects on the sex of the child (boy or girl) if was born by IVF method.
Accordingly, IVF will give birth to more boys because according to the analysis, the time of conception was treated before being put into the mother's womb.
A standard IVF means that eggs and sperm will be allowed to " resonate ," and then develop into embryonic walls with a 53% higher rate of boys.
Meanwhile, other methods such as direct pumping of sperm into the egg will reduce the chance of conceiving babies to 50%.
However, the process of transferring conceived eggs to the mother's uterus (IVF method) will reduce the chance of having a boy sooner than 2-3 days, if not later than the same number of days or more chances will increase.
According to statistics, the rate of boys in Australia is increasing, with 100 girls, 127.8 boys are born. Clearly, scientists warn, Australia is and will be faced with the problem of gender-related gender disparities like China today.
However, according to Dr. Frank Quinn, IVF hospital director in Australia, although the data "is quite serious " but the effect of gender difference in Australia due to the use of IVF method is very small, only accounting for about 3.3% of all births in this country, stemming from high treatment costs and extended time.
