Men are so obsessed about SIZE. Kinda silly, IMO.
For the purpose of this article ... I would like to suggest they do a lineup of grown men for penis inspections. I'll bet they'd find more of those small tally-whackers and that it has nothing to do with chemicals. It's just plain ole genetics. Some have little ones, and some have big ones.
Now, I'm not saying this researcher is wrong. However, enhancement surgery certainly didn't start with this one localized chemical.
BTW, when was the last time you saw an experiment like this trying to determine the cause of small breasts?
Genetics may not be the most important factor in size. Girls who are accomplished gymnasts often have small breasts while girls raised on a high fat high carb diet often develop large breasts. Chinese-American girls in general have larger breasts than girls raised in China. A Chinese boy raised on a farm in Ohio often grows up much larger than he would have otherwise. In general, what a person puts into their system for nutrition seems more significant than genetics.
I agree about size not being that important. Small or large breasts has no effect on how attractive a woman is to me. I think women who get breast surgery do so more to compete with and make other women jealous than to attract more men. Similarly, men who get penis enlargement operations are often fireman or others that must shower in front of other men.
