Male Fertility is Related to The Distance Between The Anus and Penis

The size of the male mind … to be fertile. This is not to assess and measure penis or testicles not being measured anogenital distance.

Men with a distance less than the average (about 52 mm) are seven times more likely to be subfertile than those with an AGD higher, according to a study published Friday in the journal Environmental Health Perspectives.

The distance measured from the anus to the bottom of the scrotum, is associated with male fertility, including semen volume and sperm counts, according to the team. The smaller the AGD, the more likely to have low sperm counts.

This offers the prospect of a relatively simple test of control for men, said study co-author Shanna Swan, Medical Center University of Rochester.

“It is not invasive and anyone can do, and is not sensitive to the type of things that affect sperm count, such as stress, the presence of a cold or too hot,” Swan said in a telephone interview.

Swan, who also co-author of such research, said the evidence shows a correlation between prenatal exposure to phthalates and a shorter anogenital distance. In reaching its conclusions, the researchers measured to 126 men born after 1988, a small but statistically significant, Swan said. The study did not assess what might cause some men to have a short anogenital distance.

But other previous research, published in 2005 and 2008, considered a possible link between mothers who were exposed to chemicals called phthalates during pregnancy and the AGD of male infants and toddlers.

Phthalates are a group of chemicals used in industrial products and personal care products such as fragrances, soaps, plastics, paints and some pesticides.

In these previous studies, scientists tracked the presence of phthalates in the urine of pregnant women. They found that those with high levels of chemicals during pregnancy gave birth to children who were 10 times more likely to have shorter AGD measurements than expected.

Swan, who also co-author of such research, said the evidence shows a correlation between prenatal exposure to phthalates and a shorter anogenital distance.
