They begin by saying, "Although this idea is regarded as dogma by many in the lay community and the changing of underwear type is a therapy frequently recommended by medical practitioners, there is a paucity of data measuring scrotal temperature as a function of underwear type. ("Munkelwitz, Robert, and Gilbert, Bruce R. "Are boxer shorts really better? A critical analysis of the role of underwear type in male subfertility." The Journal of Urology, 160.4 (1998) : 1329-1333.)

A) Men who wore briefs were cooler overall than men who wore boxers.
B) The type of underwear men wear has no impact on fertility.
C) The generally held idea is confirmed that men who wear boxers have cooler scrotal temperatures than those who wear briefs.
