SAN FRANCISCO, Nov. 10 /PRNewswire/ -- BabyCenter(R), L.L.C., the leading online resource for new and expectant parents, today announced the results of online polls showing that 40% of pregnant couples worry that sex during pregnancy might hurt the baby. Among expectant fathers, fear of injuring the baby has caused 30% of them to say "no" to sex. Women are concerned as well -- 21% of poll respondents say it has caused them to turn down sex. "Even couples who understand that sex during pregnancy is safe can't help but worry about it. It's natural. As soon as you find out a baby is on the way, your protective parenting instinct kicks in," said Linda Murray, BabyCenter executive editor. "You start to examine everything you do as a potential danger to your child, and anything that seems even remotely risky causes concern. In my mind, expectant fathers who say they're worried about sex harming their unborn babies are great dads-in-the-making. They're putting the well-being of their baby above their own pleasure." In addition to safety concerns, expectant moms also blame common pregnancy side-effects -- morning sickness and bloating -- for putting a damper on their sex drive. Despite these obstacles, 41% of couples say they have kept busy in the bedroom throughout the pregnancy. While BabyCenter is pleased to report that fear and bloating are not stopping everyone, 11% of respondents say they haven't had sex since they found out they were pregnant. These couples may be needlessly adding sex to the long list of real pregnancy no-no's, such as using alcohol or tobacco, eating unpasteurized cheese or sushi, skiing and horseback riding. "Unless your doctor has advised you not to have sex due to complications with your pregnancy, it's perfectly safe to keep having some fun -- and doing so is good for your relationship," said Murray. "Couples face many emotional and physical changes during pregnancy, and sex is a great way to stay bonded and enjoy being a couple before the baby arrives." For some couples, pregnancy actually enhances their sex life. According to the polls, 8% of couples say they had sex more often and 13% say the quality of their sex life improved after they became pregnant.
