I see all these penis enlargement claims is there anything medically that increases penis size?

Save your money. Professionally, I do not feel that any of the "suppliments" claiming to enlarge your penis in any way, shape, or form work. If you are so motivated you could consider a consultation with a urologist that does this type of cosmetic surgery, but my best advise would be to attempt to utilize whatever nature provided you with to your best avail. Size is important, but its not everything. Good luck.
