Womb transplant pregnancy success

The new reports that the Swedish scientists have successfully transplanted womb to four sheeps that they pregnanted after the womb transplant. This is an exciting improvement in implanting technology, but it still lacks in many parts to be used currently. Firstly, it was autologous transplant - from one to oneself, that is not from the others. This will be hardly required. The transplanted womb can be rejected after few months, and it may also occur during the pregnency, which is really dangerous. It is still required a longer time for the further side effects observance.
(However, I still find it amazing, that they could actually reconnect all those blood vessels!!)
