A drunken night on the town or romantic dinner over a good bottle of wine may seem like the perfect precursor to an evening of baby-making, but men might want to think again before pouring another cocktail. A man's sperm count can be directly affected by toxic chemicals, including alcohol. According to the Mayo Clinic, only 50 to 70 percent of a man's sperm are healthy enough to fertilize an egg. When alcohol and tobacco are added to that mix the number of healthy sperm decrease significantly.
Heavy drinking may reduce the quality and quantity of sperm. Limit alcohol to no more than one or two drinks a day. The combination of tobacco and alcohol is particularly harmful.
So if you and your partner are actively trying to conceive, it may be time to reduce the number of drinks you both consume each week. There's no harm in a little early prep work for once the baby arrives.
