A veterinarian in Australia says in vitro fertilization works so well in cattle, that there's no reason it can't work as well in humans. This will lead to a world where sex to conceive babies will not be necessary, he claims. And this literal brave new world could be less than a decade away.
This would leave sex as just an activity for pleasure.
Dr. John Yovich calls human reproduction "fairly inefficient," especially among older couples that delay having children. According to a report in London's Daily Mail, young adults have no more than a one-in-four chance of reproducing through sex. Among the over-35s, this falls to one in ten.
This compares to the near 100% success rate that Yovich believes will be possible with IVF.
Yovich, co-author of a new report in the journal Reproductive BioMedicine, said, "Within the next five to ten years, couples approaching 40 will assess the IVF industry first when they want to have a baby."
He based his hunch on the fact that IVF works almost every time in cattle. He said there was no reason that success rate could not be replicated in humans.
His co-author, fellow Australian vet Gabor Vajta, said test-tube embryo production in cattle was 100 times more efficient than natural means. He said there was no reason why IVF in humans should not become 100 times more efficient than sex.
At present, IVF has only a 50 per cent success rate, and that just among the most healthy couples.
If they are right, then the world of the sci-fi classic "Brave New World," in which all children are born in "hatcheries" could soon be closer to reality.
