QUEST FOR PERFECT CHILDREN OR GOOD MEDICINE? "The US FDA is considering approving an IVF procedure designed to do just this: weed out babies with genetic diseases ... This way, the child inherits the traits of three parents. But more insidious is the motivation: to perfect human children." More insidious? http://lnkd.in/d6bjrwN View in LinkedIn

THE FUTURE OF HUMAN BIRTH. With technical advances in recent years, the future of human birth now looks full of options. Whether any of this make any sense at all, is a separate question, but we will tiptoe through the tulips to peeks at the wild and wonderful menu of options. View in LinkedIn

"GERM CELLS that eventually turn into sperm or eggs are identical in both sexes, and whether a sperm or an egg is produced depends only by how late meiosis occurs." These are the cells that make the gametes, ova and sperm. The ova is the largest, and sperm, the smallest cells in the human body. http://www.sciencedaily.com/releases/2006/04/060404090939.htm View in LinkedIn

SPERM NO LONGER MALE DERIVED. "Female sperm can refer to those that carry an X chromosome and, after fertilization, result in a female baby, but it can also refer to the theoretical concept of making sperm from female cells instead of male cells." http://lnkd.in/dE7qjhD View in LinkedIn

FEMALE SPERM. "Since the late 1980s, scientists have explored how to produce sperm where all of the chromosomes come from a female donor. In the late 1990s, this concept became a partial reality when scientists in Japan developed chicken female sperm by injecting bone marrow stem cells from a female chicken into a rooster's testicles." http://en.wikipedia.org/wiki/Female_sperm View in LinkedIn

SPERMATOGONIA. "Scientists from the University of Newcastle upon Tyne ... discovered a method of creating partly developed sperm cells, otherwise known as "spermatogonial" stem cells, from the bone marrow of both sexes, entirely in-vitro (outside the human body), and is seeking funding to see whether such techniques can be used to make female sperm." http://en.wikipedia.org/wiki/Female_sperm View in LinkedIn

SUMMARY OF ATTEMPTS TO MAKE FEMALE SPERM, a fascinating tour of scientific strategies to permit same sex procreation. http://lnkd.in/dnr2Zzz View in LinkedIn

GENDER BENDING BIOLOGY. "There are a number of research laboratories that are focused on the creation of cells that are genetically male but have been produced from eggs ... they are also trying to create sperm from female eggs. If the research proves to work ... particularly important for gay and lesbian couples that wish to have children." http://lnkd.in/d6R6sQG View in LinkedIn

FEMALE SPERM AND MALE EGGS MADE FROM SKIN. "Skin cells from mice were used to make mouse sperm and eggs, leading to a live birth, reported by Japanese scientists in 2014. Monkey studies are to follow as a bridge to proof-of-concept in humans. This is a major advance." http://lnkd.in/d_WJcnF View in LinkedIn

IN VITRO HERMAPHRODYTES. "Hermaphrodytes have the reproductive organs of both sexes, which is true of most invertebrates and plants, or where the creatures can change sex. Being able to make sperm or egg in vitro from humans of either sex makes us technically Hermaphrodytes and changes human evolution." http://lnkd.in/d-JbBb2 View in LinkedIn
