SAN DIEGO, March 4 (UPI) -- For sex, Valentine's Day cannot compete, at least statistically, with Christmas -- the time of year couples have the most sex, U.S. fertility experts said.
Fertility Specialists Medical Group in San Diego said with Valentine's Day, cold weather ideal for snuggling and school vacations, many think that February is the month when most babies are conceived -- resulting in more births around November than any other time of the year.
