i was about to post this but i see someone beat me to it
http://www.abc.net.au/news/stories/2009/11/10/2738398.htmI think it's true, they already do some stuff a bit like this for growing skin for burns victims and i think maybe also bone, how they'd build the scaffold might be a bit of an expense/logistics issue though, a penis is a pretty complicated organ compared to a layer of skin.
I think there'd be a moderately high risk of tissue grown this way turning cancerous, so it may be a long while before they are willing to graft it onto a human without some immediate and direct threat to their life (burns, heart failure, some other vital organ not working). But being somatic cells (normal cells) rather than stem cells probably makes it a bit safer. Also not having to find ova or embryos for stem cells makes it likely to be cheaper and easier to obtain. I think it will take at least 5 years though (probably a lot longer) to get to human stage.
One thing that i'd be particularly sceptical of is that they don't seem to be saying much about nerve tissue, i'd say that was pretty important for a sex organ, but given the quality of current phaloplasty it's gotta be an improvement on that, and won't literally cost an arm. Even if i'd been more tempted before, the donor-site photos i've seen for phalo are enough to turn me right off it.
