The world’s first “test tube” puppies have been born after years of attempts, say scientists in the US.
The in-vitro fertilisation success paves the way for conserving endangered breeds and could help in the fight against human and animal diseases, say researchers at Cornell University.
The seven beagle and cross-bred beagle-spaniel puppies were born to a surrogate mother.
They were from the same litter but have three sets of parents.
Frozen embryos were implanted in a female dog using techniques similar to those used in human fertility clinics.
