The article states this is clearly for reconstruction and not for growing one from scratch. The next level up is to test with primates and then hopefully lead to where procedures as such will evolve for humans. However, if you go over to Wake Forest they might be ahead of the game as far as building one as they created one from scratch for a rabbit and it worked so there is research on both ends here with repair and building from scratch it appears.

Men in need of penis reconstruction could soon enjoy the benefits of a special ingredient: stem cells. A new study in rats shows that lacing a penis graft with adult stem cells yields better healing and sexual function than using the graft alone. The finding may point the way to improved treatments for a variety of human penile impairments.
Men with penis injuries, deformities, or severe Peyronie's disease—which causes excessive scarring that can curve or shrink the penis—sometimes need surgery to reconstruct their genitalia and restore their sexual function. Many receive a graft made of their own tissue, cadaver tissue, or pig intestines, but the surgery can cause complications, including erectile dysfunction.
"This is an excellent study, with lots of clinical implications," says Trinity Bivalacqua, a urologist at the Johns Hopkins Medical Institutions in Baltimore, Maryland. But he notes that the method applies only to reconstructions, not to cases where a surgeon may need to build a new penis from scratch. And although the technique works well in rats, "this doesn't always translate to humans," Bivalacqua says.
