(HealthDayNews) -- So much for the "old wive's" tale that couples who want to get pregnant should eschew briefs for boxers.
The reasoning went that tight briefs would elevate testicular temperature, thus hampering sperm production.
But fertility experts say it simply isn't so.
Researchers at the State University of New York at Stony Brook say they've found that briefs produced no significant differences in a man's scrotal temperature or in his sperm count, concentration or movement.
The findings applied even when men switched from one type of underwear to the other, the scientists say.
