Theoritically could stem cells be used to grow an extra penis?

I mean scientists say it could be used to replace other organs, so technically speaking they could right? I mean to perform a sex change on a women or something along those lines.

not yet - the penis is made of different types of tissue - you need skin, veins, erectile tissue, blood vessels... i'm not sure they could grow a penis without other bits (testes) because this also needs hormones to grow. just my opinion.

i suppose thats true but seriously weird dude why would you want an extra penis

It looks like some scientists from Wake Forest University Institute for Regenerative Medicine are working on it.

From the Wake Forest University Institute for Regenerative Medicine website:
"Our scientists were the first in the world to successfully implant a laboratory-grown organ into humans and today are working to grow more than 22 different organs and tissues in the laboratory."

Kidney
Esophagus
Bladder
Smooth Muscle
Cartilage
Urethra
Ureter
Vessels
Salivary glands
Trachea
Bone
Breast
Skeletal Muscle
Lung
Retina
Uterus
Heart
Testes
Nerve
Liver
Pancreas
Genitalia

I think he means as a replacement. Not two at the same time.

From the Wake Forest University Institute for Regenerative Medicine website:
"Scientists at the Wake Forest Institute for Regenerative Medicine (WFIRM) were the first in the world to successfully implant laboratory grown bladders in humans. They are now applying the principles of regenerative medicine to projects aimed at helping injured soldiers."


Im sure there are more than a few soldiers that have had their genitals blasted off.

Also, do a search for a 2003 NewScientist article: "Tissue engineers grow penis – with feeling"
