Last fall, John Zhang made headlines after his fertility clinic announced that for the first time a baby had been born using a new technique requiring three genetic parents. The baby’s mother carried the genes for a fatal nervous system disorder called Leigh syndrome, but Zhang had been able to keep the disease from…
A medical lab in the Netherlands is admitting that a “procedural error” may have caused upwards of 26 women to have their eggs fertilized with the wrong sperm.
Using skin cells extracted from mice, researchers in Japan have produced fully functional egg cells that were used to produce healthy mouse pups. Should the method work in humans, it could introduce powerful new ways of treating infertility—and even allow same-sex couples to produce biological offspring.
A popular fertility treatment introduced in the early 1990s has been linked to low sperm counts in men born from the procedure. Scientists aren’t entirely sure why this is happening, but it’s entirely possible that fathers are passing their fertility issues down to the next generation.
A new reproductive technique in which a baby is produced with the genetic material from three distinct parents has yielded its first human.
For the first time ever, scientists have produced live mice without a fertilized egg cell. The potentially revolutionary technique could one day allow gay men to produce biological offspring, or—even more radically—allow both men and women to self-fertilize.
It’s been 20 years since the birth of Dolly the Sheep, the first mammal to be cloned from an adult. Because Dolly died prematurely, scientists have worried that cloning accelerates the aging process. But a new analysis of 13 cloned sheep—including a batch of Dolly’s genetic duplicates—shows this isn’t the case.
Scientists say a groundbreaking fertility treatment to correct potentially harmful genetic mutations has the potential to backfire, recreating the exact mutation the intervention was meant to fix. It’s a problem that could put an immediate halt to the pending practice—but a work-around may be possible.
Some men produce sperm that are poor swimmers, a major cause of infertility. To help, researchers from Germany have developed motorized cyborg “spermbots” that can be guided directly to an egg.
If you’re trying to save an endangered animal, you need to protect its habitat and change the human behaviors driving it toward extinction. But all that will be meaningless if the animals don’t have babies. And so sometimes, you have to help with that, too.
A group of geneticists has called for a moratorium on research into modifying heritable human DNA — a practice that could lead to so-called "designer babies." But as scientists consider this drastic proposal, they should also recognize the potential benefits this technology could afford – and the risks of an outright…
The government of Ontario recently announced that it's going to start providing limited coverage for in vitro fertilization, making it the third Canadian province to do so. But is assisted reproduction something states should be paying for?
We've been thoroughly enjoying Orphan Black, BBC America's show about a young woman who discovers, to her shock, that she's a clone. But what if, instead of being an orphan with no knowledge of her genetic heritage, Sarah was raised by loving parents? How might they try to ensure she grew up to be a happy and fully…
In vitro fertilization was developed well over thirty years ago, but its far reaching potential for helping couples with fertility issues has yet to be fully explored. The most recent reminder of this arrived on September 5, 2012 when a baby girl named Elle Cynthia was brought into this world via cesarean. But unlike…
A number of years ago we reported on how a "three-person IVF" procedure could be used to stop serious conditions from being passed from mother to child. The prospect caused serious concern among many scientists and ethicists. But now the BBC is reporting that a bioethics council is green-lighting the treatment.
