Reproduction revolution on the horizon Enlarge this image toggle caption Lluis Gene/AFP via Getty Images Lluis Gene/AFP via Getty Images It's a Wednesday morning at the National Academies of Sciences, Engineering and Medicine in downtown Washington, D.C., and Dr. Eli Adashi is opening an unprecedented gathering: It's titled "In-Vitro Derived Human Gametes as a Reproductive Technology." "This could be life-altering for individuals to build that family that they dream of through IVG," says Andrea Braverman, who studies infertility at Thomas Jefferson University in Philadelphia. Provocative possibilities Another theoretical possibility is "solo IVG" — single people having "uni-babies" — babies with just one person's genes, says Dr. Paula Amato, a professor of obstetrics and gynecology at the Oregon Health & Science University in Portland "In theory you could reproduce with yourself. "One law we definitely need is to make sure people can't become genetic parents without their knowledge or consent," says Greely.

New ways of making babies are on the horizon

Live Mint  

The human genome can create cells with a remarkable range of capabilities and shapes. To make eggs from mouse cells means coaxing iPSCs into becoming cells that look like “primordial germ cells", common ancestors to egg and sperm. Dr Saitou has achieved the same thing using blood cells and, by incubating the products with reconstituted mouse ovaries, has nudged them …

Scientists Create Synthetic Embryos Using Stem Cells, Without Sperm Or Egg: Report

ABP News  

Stem cell research is advancing, and has made it possible to create synthetic embryos without a sperm or an egg. Researchers recently used stem cells to create synthetic embryos, without a sperm or an egg, The Guardian reported. Quoting Żernicka-Goetz, the report said human embryo-like models can be created by the reprogramming of embryonic stem cells. Quoting Robin Lovell-Badge, the …

Scientists create mice using cells from two males for the first time

LA Times  

Scientists have created baby mice using cells from two males for the first time. First, they took skin cells from the tails of male mice and transformed them into “induced pluripotent stem cells,” which can develop into many different types of cells or tissues. Laird also said scientists need to be mindful of the mutations and errors that may be …

Hope for infertile men as sperm is grown in lab from RAT cells in groundbreaking research

Daily Mail  

Infertile men have been given hope after scientists created sperm from the stem cells of rats. But scientists have now created lab-grown sperm cells which, after being injected into male rats, were used to create babies. About one in seven couples have trouble conceiving and in about half of cases the problem lies with the man Infertile men have been …
