According to Penny Lancaster, wife of Rod Stewart, her husband stopped wearing tight pants on the advice of a doctor.

At the time, notes Penny, the pair were trying to conceive their second child.

"When Rod and I were trying to make our second child, we were having a few troubles and a doctor said, 'Rod, you've got to forget wearing the tight pants and trousers, OK?

Get rid of the Calvin Kleins, do the loose boxer shorts, and no hot baths,'" Lancaster revealed on ITV's Loose Women.

She added, "I then spoke with a famous celebrity chef, who was having similar issues. They told him one of the problems was he was always standing by the oven."

"So anyone out there, any men, don't use this as an excuse necessarily but if you're trying to make a baby and are having problems, don't go near the oven!"
