Human Sexuality 7 of 8
A new Italian study of male sexuality has discovered that the average size of male genetalia has been steadily shrinking over the past several years.
- Male genitalia are roughly 10 percent smaller today than they were 50 years ago.
- Excess weight gain, particularly around the waist, is a contributing factor.
- Environmental pollutants in the air have been shown to negatively impact penis size.
- Stress, smoking, and alcohol intake also play a factor.
So much for all of that locker room bravado, boys.
