STOCKHOLM (September 18, 2012)--Doctors in Sweden say they have performed the world's first mother-to-daughter uterus transplants "without complications."

The specialists from the University of Goteborg said two women received wombs from their mothers in surgical procedures on Sept. 15 and 16.

The university said one the uterus of one of the recipient’s was removed many years ago because of cervical cancer and the other was born without a uterus.

Both women are in their 30s.

Team leader Mats Brannstrom said both "are doing fine, but are tired after surgery. The donating mothers are up and walking and will be discharged from the hospital within a few days."

Turkish doctors last year said they performed the first successful uterus transplant, giving a womb from a deceased donor to a young woman.
