I have had erectile dysfunction for many years due to venous leakage. I've had dorsal vein ligation surgery before, but I didn't see any benefit. My teacher Yaşar told me how detailed venous surgery should be done. It was then that I realized that the first operation was in vain. My teacher did venous surgery. He applied stem cell therapy to him. He did my 6 month check up today. My Doppler result improved completely. Now I can get an erection without using drugs. How grateful I am.
