According to medical journal The Lancet, laboratory grown female vaginas have now become a reality, as four women were implanted with them in a Mexico City hospital between the years 2005 - 2008.  The women who underwent the procedure were suffering from a very rare condition known as Mayer-Rokitansky-Kuster-Hauser syndrome, which "causes one in 4,500 girls to be born without a vagina or only a partially developed" one, according to a report from Rollingout.com.  The remedy for this syndrome was very risky, as in past years the complication rates were as high as 75 percent for patients who either had reconstructive surgery or underwent very painful dilation in order to further open the vaginal canal.

The procedure involves taking cells from the patient that are attached to a biodegradable lattice, which is then sutured into the patient's existing reproductive system.  After several weeks, the genetically engineered tissue begins to attach to the patient's nerves and blood vessels, which is what forms the fully operational vagina.  

One patient reported during an 8 year follow-up that she was having sex pain-free and also experiencing the pleasures of orgasms.
