Sunny vacations bad idea for hopeful fathers

Especially during the summer months, many couples will take a relaxing vacation when trying for a baby. However, recent reports from fertility experts suggest this may be the worst thing a hopeful father can do.

According to Australian researchers, too much heat can not only reduce sperm count, but also slow down those that survive.

They began their research after doctors at assisted conception clinics have recently noticed what they've come to believe is a "season effect" on men's sperm counts, but as far back as the 1950s some believed that men could take regular hot baths as a means of contraception.

That said, this report was conducted in England, a country infamous for its long months of cold, rainy weather. As noted by a UK fertility expert: "If there was a major effect, I think we would see people having problems conceiving in every country in the tropics."

But, he adds, "it's worth being cautious."
