"Basically, there's two major procedures, very different ones. One you use everything you already have, which grows from the hormones and is fully functioning but smaller than the average male's penis.
"The other takes skin grafts from areas that could make those areas not work as well and not having as much feeling as you had before, not having as much sensation, and needing help to function."
Chaz - who has been in a relationship with Jennifer Elias for five years - also told how well he's been accepted by the male community, in particular when it comes to using public bathrooms.
He said in an interview on Australia's 2Day FM radio station: "The first time it was a little scary, you don't want to get hurt, have some person beat you up or something, so I was little scared for a time, but it really isn't a big deal at all, no.
"And guys really don't care, that's the thing. Women are so much more scared going to the bathroom, men don't even think about it."
