Non-smokers mothers whose husbands smoked gave birth to boys more seldom also.
The research was carried out by pediatricians group under the direction of professor Bernard Brabeen. Scientists discovered that substances containing in cigarettes, e.g. nicotine , prevents spermatozoon with male chromosomes to get ovule.
“The purpose of research was to find out if the sex of the future baby depends on mother smoking during pregnancy. When we corrected the results became clear that the chance to give birth to a girl double when mother smokes pregnant. We do not know why. We suppose this is because of spermatozoon with Y chromosome which is responsible for boys. This spermatozoon is more sensitive to negative changes in the mother’s organism.”, tells Brabeen. .
