It s more a psychological and positive thinking that helps than medicine which will help you regain penile strength. According to Ayurveda, deterioration of Shukra i.e. semen results in deterioration of preceding six elements too. So when Saptadhadhtus ( seven elements) deteriorate, a lot of diseases and impotency takes place. As far as erectile dysfunction is concerned, constriction in penile vessels and cavernosa causes hinderance in proper blood filling upon stimulation and erection. Ayurveda has the answer. Dhatupaushtik herbal combo and application of special oils on penis and wrapping by medicinal leaf for so.e days enriches dhatus - the elements including Shukra the Semen and dilates vessels of penis. This gives you stout penis upon erection. All this cycle ideally needs seven weeks. Some food protocol have to be followed. Hope it helps. Pl consult any Ayurveda physician or contact me for further guidance through direct question.
