Short of cosmetic, reconstructive surgery, there's not really much you can do. There are no magic pills – drugs or herbal – that are going to do it for you. Any of these that have any actual safe effects just promote effective blood flow within the penis, which is what's responsible for causing an erection. Increasing the bloodflow safely in the penis will allow the fullest erection you can physically have, or might prolong erection. But you can't get a bigger penis in this way safely.
The US marshal for the Southern District of Ohio, which collected and sold Warshak's valuables to pay his judgment, did a thorough job of tracking down his property—but the marshals couldn't find the Segway, which Warshak's family had reported stolen. Three years later, the Segway resurfaced in the abandoned property room of the local sheriff's office. Someone had found it by the side of a highway back in 2008; it took until 2011 for police to realize that it was the missing Warshak scooter. In May 2012, after the gear had all been sold, the Department of Justice released $24 million to repay Berkeley victims.
Using penile extenders involves hanging a weight off the penis for hours at a time, which doesn't increase size. To the contrary, this can cause tissue damage and there have been reports of it causing Peyronie's disease (curving of the penis). Rather than resulting in enlargement, using penile extenders could cause injury and have a negative effect on your ability to get an erection.
The challenge was how to properly extract the tissue and also how to resolve three related problems. For a number of years some plastic surgeons performed “fat grafts” as a technique for penile enhancement. However, such approaches were known to eventually deteriorate into a clumpy, unhealthy form. Additionally, the body tended to reabsorb the bulk of that implanted tissue causing a loss of increased size. Finally, the technique offered no opportunity to increase penile length – a common patient request with augmentation.
