Due to cancer I had my penis removed is it possible to re gro 1 with stem cells?

No. Stem cells are a very exciting area of research, but need to be stimulated to replicate particular cell types.Penis consists of numerous cell types, skin cells, urethelial (lining of urethra), erectile tissue and fascia.Presently urethelial cells can and are grown & used in penile reconstruction.Other penile cell types have not yet been grown.Scrotum can be moved back if you had partial penectomy.
Not yet. Science is not there yet. Researchers are working on the technology but it's still a long way off especially when multiple tissues are involved. Sorry.
