Is there a uterus implant?

I have heard that there was the first uterus implant done in another country, and subsequently heard that they were studying implanting uteri in the U.S. The U.S. has not perfected a method of a permanent uterus implant, however. The method they are studying now includes anti-rejection drugs so that the woman the uterus is implanted to can have the uterus implant until after she gives birth, then it is removed. I am hopeful that they will continue this study, but I have heard that many people find a uterus implantation ethically "wrong", fearing that men will ask for this implant.
