Penis size Affect Fertility

Size does matter. That principle held by men in matters of sex. Although women are not required to satisfy a large penis size, according to a recent study found an effect size of penis is also on fertility.

Penis size is referred to here is the length measured from the anus to the scrotum or called anogenital distance (AGD).

According to research published in the journal Environmental Health Perspectives, the size of the AGD this could be one of the instructions are simple but quite accurate fertility.

Shanna Swan, professor of obstetrics and gynecology at the University of Rochester, USA, who conducted the study, said that AGD is closely related to the amount of seminal fluid and sperm cell count.

Median AGD was about 2 inches (5.08 cm). Men who measure of AGD was shorter than that number have a risk of infertility seven times higher compared with men who AGD was longer. The man who was short AGD also tend to have fewer sperm count or less than 20 million per millimeter.

Men who have low sperm counts are usually also be difficult to impregnate his wife. A normal sperm count is 50-60 million sperm cells per millimeter.

Initially, studies conducted Swan is not intended to analyze on fertility. However, initial results of research conducted on 126 college students found that pregnant women exposed to chemicals in plastics called phthalates tend to give birth to males with short AGD size.

In 2005 and repeated in 2008, Swan found that pregnant women exposed to high levels of phthalates in the would give birth to a baby boy with AGD size and penis size shorter.

Although the current size of AGD has not been used as the standard in fertility tests, Swan said, the size of the AGD could be additional data for the examination conducted fertility doctor.

"Currently AGD test is not yet recommended, but with further research it is not possible it will happen," he said.
