Gynecologists studied the alcohol habits of 500,000 Chinese couples and concluded that men who drink alcohol six months before conception are more likely to father children with disabilities, reports the Daily Mail, citing the scientific journal JAMA Network.
In the study group, only three percent of women drank half a year before conception, while the number of future fathers drinking was over 30 percent. As a result, 609 out of 500 thousand couples had children with congenital abnormalities. The most common defect is the cleft lip, an incision in the upper lip that forms during fetal growth. The results of the study prove that the pre-conception lifestyle of fathers also affects the development of the baby in the womb.
According to study author and gynecologist Xiaotian Li, “drinking alcohol increases the risk of sperm abnormalities,” and future fathers should stop drinking before conceiving.
