I figured this out well Rheinschild’s, okay they attach the grafts at the base of the pubic bone and the other end at the glans, so if you do stretching excercises it will grow with your penis! Rheinschild says that he has no preference for alloderm or dermal grafts. Either one is good, it is just that Alloderm has a rare occurence of infection usually from patient not giving good care. The infection rate is around 1%, not bad that is lower than some normal surgeries. Anyways they are both good surgeries but if you wanna have sex a bit quicker dermal graft is better, but if you don’t mind the wait then go for the alloderm! Good luck guys!
