The world's first "test tube" puppies have been born after years of attempts, say scientists



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.

Problems with freezing embryos have caused difficulties, but the group say they have perfected this and other techniques.

Lead researcher Dr Alex Travis, from Cornell's college of veterinary medicine, said: "We have seven normal happy healthy puppies." He added: "Since the mid-1970s, people have been trying to do this in a dog and have been unsuccessful. Now we can use this technique to conserve the genetics of endangered species."

I think they need to do more trials
