Between this and that injected medicine discussed on the TER Altanta board, there must be some really desperate men out there who are willing to stick needles into their equipment.

Being in the alternative health field for over 7 years, and having studied Tantra & sensual arts, I've never known anyone to benefit from accupuncture as treatment for ED.  This does not mean it's impossible,  If this is something you're really wanting to try, I'd suggest you find  a very reputable and
experienced practitioner.  You could also use this in conjuction with Tantra and possibly hypnotherapy.
Do your research.

You will find a number of articles and links. I have attached a link to an interesting case study. Check out also the University of Maryland Medical Center Complementary Medicine page.
