The first IVF Dogs have been carried out by Cornell University, find out more from reading the article on Wired UK –
Research in the area has been ongoing since the 1970s, but has only now been successful. The breakthrough was a result of overcoming two problems: collecting mature eggs from a female and making the sperm viable within the body.
The first issue stems from the fact dogs’ reproductive cycles are different to other mammals, meaning finding eggs at the right stage of cell maturation was difficult — researchers overcame the problem by leaving the egg for one more day. And the second — the fact that, normally, the female tract prepares sperm for fertilisation — was overcome by adding magnesium to the female’s cell culture.
Overall, nineteen embryos were transferred to the surrogate mother, leading to the birth of seven healthy beagle/cocker spaniel mix puppies. And the findings could have “wide implications” for conservation, according to Travis.
“We can freeze and bank sperm, and we can use it for artificial insemination,” he said. “Now, we can use this technique to conserve the genetics of endangered species”.
The research, undertaken by Cornell University in New York, may now provide breakthroughs in conserving canine species, studying genetic diseases and even using gene-editing technology to eradicate diseases in dogs.
