A women in Sweden gave birth to a baby boy last month, and it was nothing short of historic: the baby is the first child to be born from a transplanted womb. His mother, a 36-year-old woman, received a uterus from a family friend last year, the Associated Press reports. And although her baby was born prematurely by C-Section, both mother and child are well.

It’s "still sinking in that we have actually done it," Mats Brannstrom, an obstetrician at the University of Gothenberg, told the AP.

The donor had gone through menopause already

The news is a big deal for science and women in general, but it’s especially important for people living in Sweden, where surrogacy isn’t legal, reports The Washington Post. The mother was born without a uterus (but with functioning ovaries), which means that she would have been unable to have kids of her own without the surgery. Still, even after the transplant, Brannstrom was unsure whether a pregnancy would be possible. The donor was 61-year-old woman who had given birth to two kids. She had also gone through menopause.

The transplant's aftermath wasn't easy. The mother came close to rejecting the organ three times, including once during the pregnancy. Fortunately, her doctors were able to use drugs to prevent her body from rejecting the organ.

It’s too soon to tell whether the mother will be able to carry a second child to term, Brannstrom said. But the parents really aren’t thinking about that just yet. "Right now," the father said, "we're very happy with just one baby."
