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 the size of the penis is also an effect on fertility.
Penis size is meant here is the length measured from the anus until the bottom of the scrotum or called anogenital distance (AGD).
According to research published in the journal Environmental Health Perspectives, the size of the AGD 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, AGD is closely related to the amount of semen and number of sperm cells.
AGD median figure is about 2 inches (5.08 cm). Men who measure of AGD was shorter than the risk of infertility rate seven times higher compared with men who AGD was longer. The man who was shorter 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. At first, research conducted Swan is not intended to analyze the fertility.
However, preliminary results from a study of 126 college students found that pregnant women exposed to chemicals in plastics called phthalates tend to give birth a baby boy with short AGD size.
In 2005 and repeated in 2008, Swan found that pregnant women exposed to high levels of phthalates will give birth to a baby boy with the size of the AGD and the size of the penis is shorter.
Although the current size of the AGD has not been used as a standard in fertility tests, Swan said, the size of the AGD could be additional data for fertility doctor do the examination.
"Currently AGD test is not yet recommended, but with further research it is not impossible it will happen," he said.
