Three-Parent Method May Help Eliminate Hereditary Diseases
2013-03-20 18:37:03

Brett Smith for redOrbit.com — Your Universe Online British officials are debating whether or not to legalize new in vitro fertilization (IVF) techniques that would eliminate dangerous hereditary diseases, but would essentially create a child from three different parents. According to the UK´s Human Fertilisation and Embryology Authority (HFEA), a public consultation in 2012 indicated UK citizens mostly support the use of the potentially life-saving technique, despite any...

Insect glands are responsible for producing a host of secretions that allow bees to sting and ants to lay down trails to and from their nests. New research from Carnegie scientists focuses on secretions from glands in the reproductive tract that help sperm survive and guide the sperm on the trip to fertilize an egg. The gene that controls the development of these glands in fruit flies provides important information about gland development in all insects, as well as potential clues to similar...

A British expert panel said on Tuesday that more research is needed before "3-parent" fertility treatments designed to prevent some incurable diseases can be considered safe for clinical use. The Human Fertilization and Embryology Authority (HFEA) said the evidence suggested the methods were safe, but more laboratory experiments should be done before they are used in clinics. The techniques involve intervening in the fertilization process to remove faulty mitochondrial DNA, which can lead...

A fertility treatment designed to prevent some incurable inherited diseases, opens the possibility that children could be conceived from three biological parents. British Health Minister Andrew Lansley asked the Human Fertilization and Embryology Authority (HFEA) to assess three-parent in-vitro fertilization (IVF) after researchers said they had mastered the technique using cloning technology, Reuters is reporting. Newcastle University has refined the technique which swaps DNA between two...

Most of us probably think of sperm as rather active little cells, swimming with quick movements of their "tail" or flagella. But actually sperm's motility is in fact short lived. When in the male reproductive tract they have to rest easy, lest they wear themselves out prematurely and give up any chance of ever finding an egg. Scientists have long known that sperm's activity level depends on their internal pH. And now -- after many years of looking "“ researchers reporting in the...

Scientists at Leeds and Bradford have discovered a unique "ËœDNA signature' in human sperm, which may act as a key that unlocks an egg's fertility and triggers new life.Drs David Miller and David Iles from the University of Leeds, in collaboration with Dr Martin Brinkworth at the University of Bradford, have found that sperm writes a DNA signature that can only be recognized by an egg from the same species. This enables fertilization and may even explain how a species develops its...

A sperm and egg donor shortage in Britain means a ban on paying people to donate should be repealed, the head of the government's fertility watchdog says. Paying donors could cut the number of childless couples traveling abroad for treatment, Lisa Jardine, chairwoman of the Human Fertilization and Embryology Authority, told The Times of London. The agency regulates and inspects all British clinics providing in vitro fertilization, artificial insemination, and the storage of human ova, sperm...

British scientists said a new genetic test can screen embryos for almost any known genetic disease in embryos that are just days old. The Times of London said the "genetic MoT" test will allow couples at risk of passing on gene defects to conceive healthy children using IVF treatment. Currently, only 2 percent of the 15,000 known genetic conditions can be identified through early testing. The test, developed at the Bridge Centre in London, involves creating embryos by in vitro...

Scientists at the University of Liverpool have found that field mice have evolved a unique way of ensuring faster fertilization, a phenomenon which could explain some cases of infertility in humans. The team, in collaboration with Charles University, Prague, found that field mice sacrifice some of their immunity protection in favor of a more rapid fertilization process. This occurs due to the absence of a protein, called CD46. Present in both animals and humans, it helps protect the body's...

LONDON (Reuters) - Internet Web sites supplying sperm to single women and lesbian couples face regulation under proposals to be unveiled by the government on Tuesday. Public Health Minister Caroline Flint will launch a three-month consultation aimed at bringing up to date the 1990 Human Fertilisation and Embryology Act. The review of the 15-year-old legislation will ask whether the sperm Web sites should be banned altogether or just more tightly regulated. The companies running the...
