I would do it in a heartbeat. I would love to have children of my own or my (future) partner's decent if I could. If I couldn't then I'd adopt, but I'd like to have a kid who's biologically connected with me if possible.
I read in the news a while back that they've made a breakthrough in transferring male DNA to eggs to create offspring with male/male parents - in animals that is. But I'm sure it won't be long before that can happen with people, which is pretty damn exciting.
