Recent findings suggest that men who consume alcohol before conception may significantly increase the risk of their child developing congenital heart defects. Traditionally, the burden of behavioral adjustments has fallen on women as they prepare for motherhood. Past studies have already established a link between alcohol use during pregnancy and various health issues in offspring, including congenital anomalies.
However, this new research sheds light on how men’s drinking habits can also affect the health of future children. According to the groundbreaking study published in the European Journal of Preventive Cardiology, expectant fathers who drink alcohol in the three months leading up to conception face a 44 percent greater chance of having a child with congenital heart defects compared to those who abstain. The situation worsens for binge drinkers—those consuming five or more drinks at a time—who show a staggering 52 percent increased risk. In contrast, mothers who drink moderately or binge drink only see a 16 percent rise in risk.
Congenital heart diseases, which affect approximately 1.35 million infants annually, represent the most common type of birth defect. Even with surgical intervention, these conditions can have lasting effects, including a higher likelihood of cardiovascular issues later in life. Moreover, they are a leading cause of perinatal mortality.
This study reinforces previous research indicating that alcohol can alter the DNA in developing sperm. Despite confirming this association, researchers have yet to uncover the underlying mechanisms behind it. “Binge drinking among prospective parents poses a serious risk, not only potentially increasing the likelihood of heart defects in their children but also harming their own health,” remarked study author Nathaniel Brooks from the Institute of Public Health, University of Southern California.
While conception is often unpredictable, Brooks advises that couples planning to start a family should abstain from alcohol. Men, in particular, should aim to stop drinking at least six months before attempting to conceive, while women should cease consumption a year in advance. This further emphasizes that prospective fathers must recognize the impact of their lifestyle choices on their children’s health.

In summary, recent studies highlight the importance of paternal health prior to conception, suggesting that men should avoid alcohol for at least six months to help mitigate risks associated with congenital heart defects in their future children.
