WEDNESDAY, May 11 (HealthDay News) -- It may be possible to assess a man's fertility by checking his "anogenital distance," the gap between his scrotum and anus, a new study suggests.
Previous studies in animals have shown that anogenital distance is an important measure of genital development and may be shorter in males with abnormal development and dysfunction of the testicles, the Baylor College of Medicine researchers explained.
Furthermore, a study from the University of Rochester, published in March in Environmental Health Perspectives, found that men with shorter anogenital spans had lower sperm counts, poorer quality sperm, lower sperm concentrations and lower motility.
Curiously, they don't tell how short an anogenital distance is indicative of infertility in this article so you probably won't catch the guys in your house heading to the bathroom with a ruler just yet.
On another note, how would you like to be the researcher who's job every day was to measure the anogenital distance of strange men? That's almost as bad a job as the janitorial position for the guy who has to clean the elephant's pen at the zoo.
