5 / 9 Rumored Sperm Killer: Wearing Briefs
"Tighty whities," or briefs, are often implicated as a sperm killer that can lead to infertility because the testicles are held more tightly against the body. But here again, Dr. Kaufmann said, the concerns about sperm quality and sperm count are largely unfounded. "Most wives will have their husbands switch to boxers, but they do not need to do so," he said. "The thought is that briefs keep the scrotal temperatures elevated and could damage sperm, but the impact is not enough to make a difference for men's health."
