The world’s first litter of IVF puppies have been born to a surrogate mother in the United States.
All seven pups, who have three sets of biological parents, are said to be healthy and doing well at New York University .
They were born after 19 embryos created by in-vitro fertilisation were transferred to the host mother,
a beagle.
Two were the result of pairing eggs and sperm from a beagle mother and cocker spaniel father. The other five were from two pairings of beagle mothers and fathers.
The scientists involved used similar techniques as those offered to childless couples in IVF clinics. Success followed four failed attempts when embryos were transferred but did not result in IVF pregnancies or births.
The research is reported in the online journal Public Library of Science ONE.
IVF will in future allow conservationists to ensure the survival of endangered dog species, and to preserve rare breeds. See more photos of the adorable 7 puppies below:
