Never heard of that, but my husband had a penis size problem. I found him these herbal supplements, i forget the name, big x plus or something like that, search it and I'm sure you'll find it. It helped my husband increasing bloodflow to the penis, he gained an inch in length as well. It says you can gain 3 inches, but that wasn't so in my experience. It took about 3 months before we saw results...hope this helps...
good luck,
Sally
