I recently had a penile prosthesis surgery. I had the AMS 700 LGX. It has been over two months now since the operation. Everything is fine and I am very pleased so far. To those who had this surgery, can you do exercises such as sit ups and push ups, or exercises to flatten your stomach after the recovery period? I am concerned because the reservoir of the implant is placed in the abdomen and I not sure if the exercise would not affect the reservoir. My doctor said that it would be fine to do such exercises, but I am not too sure. I am still concerned.
