From A New Paper article
THE study shows that Indian men are twice as likely as Chinese men to have erectile dysfunction.
Dr James Tan, consultant urologist and principal investigator of the ED study, said: "Indians seem to have twice the risk of having ED compared to Chinese.
"No reason is immediately apparent in our study."
Hmm interesting ..well I think maybe its because Indians are usually way bigger in that department so its harder for us to get it up ? ;)
