Doctors used stem cells to "create a neovagina." One of every 4,000 to 5,000 girls is born without a vagina. Until now, doctors fixed this by making a vagina from skin grafts or intestinal tissue, which involved painful, invasive surgery. The new method grows vaginal tissue in the lab using stem cells derived from tissue where the vagina should have been. The lab-grown tissue is then grafted onto the donors. Approved conclusion: Now every woman can have a vagina. Unapproved conclusion: Now every man can have a vagina without a woman.
