My Friend 28m having venous leak from past one and half year, consulted many doctors and researched on it, apart from the surgery there is no other way of treating it. (He is using Viagra as of know) and the surgery is also doesn't give life time recovery is that we heard. Recently read about stem cell therapy, we would like to know how effective is this for venous leak? Does it completly heals venous leak ? And how much it costs in India. Kindly help us...
