The eKegel will definitely add weight, length, and girth to your penis because stronger muscles will create volume and there is more blood flowing into the area. It is hard to say how much because it depends on where you are starting from. It's fair to expect up to 1/2 inch improvement in length. As for the girth, that also depends, but your erections will definitely be harder, which should increase the circumference of your penis, which could increase by up to 1/2 inch as well.
