Propecia Killed my Erection

[Dr Dan McGrath]

Dear Aznstan,
Great question. The truth is that all the hair on your head is going to be affected to one degree or another by the presence of DHT.
The donor hair we use for transplant should not be affected to any great degree such that it would not grow. Having said that though when you look at the donor hair region of a patient who uses propecia you can't argue with the fact that the hair in its caliper size(shaft size) gets bigger.
So the use of propecia in a hair transplant is twofold really, protecting the existing hair and helping to thicken up the donor hair which of course will translate into a better cosmetic result with the transplant.

Hope this helps,

Dr Dan
