embryos

The FDA has cracked down on the doctor who created the first three-parent embryo, which could have widespread implications for other advancements in the controversial field of human genetic modification.
Getting or staying pregnant is not easy for everyone -- for some, it can take time and money. While you might not be thinking of having kids right now, having a conversation with a physician about fertility while still in your early 30s could provide benefit later on.
For them, dealing with the challenges of infertility can be as stressful as having cancer. Fortunately, the latest advances in in vitro fertilization (IVF) are giving them a better chance than ever of achieving their dreams.
Heterologous Embryo Transfer (HET) is the transfer of a genetically unrelated embryo into the uterus of a woman. In its most basic form it raises few eyebrows, as surrogacy is relatively common practice. However, the introduction of the phenomenon of embryo adoption has complicated HET.
The recent call by U.S. scientists for a temporary pause "in the application of germ-line modification for clinical application in humans while the implications of such activity are discussed" has added a new intensity to the debate and reveals a potential bioethical divide between the US and the UK.
I believe that we as bioethicists have a responsibility to try and bring to the surface the underlying forces that that shape the ethical boundaries of a particular debate in a country versus another. Political, social and economic factors shape ethics and policy making as they shape science and technology in different ways in different countries.
What happens when there is a dispute between the parties who used fertility to create a child? What happens to the embryos that are cryogenically preserved when the parties have a dispute as to whether they can be implanted, or the prospective parents separate?
Myriad Ethical Challenges The ethical challenges physicians, regulators, professional societies, and ethics committees confront
The moral dilemma here is this: Should one person's right be a parent outweigh another's not to be forced to become a "genetic parent" against their will?
Corrado Spadafora's work 20 some years ago on the organization of chromatin in sperm cells revealed that "sperm cells can behave as vectors of foreign genetic information to embryos at fertilization."
A long way from designer babies. While the gene-editing tool successfully spliced DNA in 28 of the embryos, it only replaced
Republican Rep. Tom Kirby, who has served since 2012, has posted a list of his top issues on his website. Among them he names
Just watch for yourself in The New York Times' trippy video above, which traces the colorful dance of cells in developing
As uses and users of wireless transmitting devices are skyrocketing in our homes, schools and even our national parks, one would think that scientific research on the human health and environmental implications of wireless electromagnetic radiation would be exploding with fierce competition.
PGD is by now a well-established procedure in reproductive medicine. Although its use may continue to give rise to some ethical controversy, the benefits to couples and the children they produce outweigh the potential negative consequences feared by some.
It takes 21 days for a chicken embryo to develop. Ever wonder what happens inside the egg between the day it's laid and the
There are large social and ethical considerations that mitochondrial replacement forces us to confront. Most importantly, this technology raises one of the thorniest questions humanity will ever face: are we willing to genetically modify future generations of humans?
