A hospital says a Turkish woman who became the first person to successfully receive a donor womb is six weeks into a "healthy" pregnancy.
Derya Sert was born without a womb and had one transplanted in August 2011. Using one of her own eggs, doctors placed an embryo into the 22 year old's womb in March.
A statement from Akdeniz University Hospital on Monday said doctors have monitored a fetal heartbeat and that the pregnancy is going well.
A successful birth would provide hope for women who were born without a womb or who lose it to disease.
