STOCKHOLM – Two Swedish women are hoping to get pregnant after undergoing what doctors are calling the world’s first mother-to-daughter uterus transplants.
Specialists at the University of Goteborg said they performed the surgery over the weekend without complications but added that they won’t consider it successful unless the women give birth to healthy children.
“That’s the best proof,” said Michael Olausson, one of the surgeons.
One of the unidentified women had her uterus removed many years ago because of cervical cancer, while the other was born without a womb. Both are in their 30s.
They will undergo a year of observation before doctors attempt to help them get pregnant via in vitro fertilization, in which embryos created with eggs from their own ovaries will be implanted in their wombs.
Researchers around the world have been looking for ways to transplant wombs so that women who have lost a uterus to cancer or other diseases can become pregnant.
Fertility experts hailed the Swedish transplants as a significant step but stressed it remains to be seen whether they will result in successful pregnancies. Even if the approach works, it is unclear how many women will choose such an option, given the risks and the extreme nature of the operation compared with, say, using a surrogate mother.
Turkish doctors last year said they performed the first successful uterus transplant, giving a womb from a deceased donor to a young woman. Olausson said that woman is doing fine, but he wasn’t sure whether she has started fertility treatment.
