    Scientists grow eggs from five-year-old girls

    Scientists grow eggs from five-year-old girls

    Scientists have grown eggs from tissue taken from five-year-old girls meaning future childhood cancer sufferers could go on to have children of their own.

    Children and young people who go through cancer are often left infertile by the treatment and are faced with having to use donated eggs and sperm or adopting to have their own family.

    The problem is especially difficult for children who develop cancer before they reach puberty because they cannot freeze their own eggs and sperm.

    But now scientists have managed to grow eggs in the laboratory from samples of ovarian tissue taken from girls as young as five.

    Immature eggs can be removed from the tissue and grown to maturity in special culture.

    The next step will be to see if they can be fertilised to create viable embryos. These could then be frozen and stored for future use or the unfertilised eggs could be frozen using the latest techniques which have proven more effective.

    Between 1,500 and 1,700 children under the age of 15 are diagnosed with cancer each year and half of those are under the age of five.

    The most common form of cancer in children is leukaemia, which affects 35 per cent, followed by brain or spinal tumours.

    Research published online in the journal Fertility and Sterility revealed that a team at Hadassah Hebrew University Medical Centre in Jerusalem examined the ability to remove and preserve ovarian tissue from young female cancer patients and then retrieve, mature and freeze eggs from that tissue.

    They worked with 19 patients between the ages of five and 20. On average they were able to retrieve an average of nine eggs per patient and 34 per cent of them were successfully matured.

    "As our ability to treat childhood cancers improves, it becomes more important that those survivors are able to live rich, full lives, including the ability have children," said David Adamson, MD, President of the American Society for Reproductive Medicine.

    "This research helps move us to the goal of allowing paediatric cancer survivors to become parents." Fertility doctors have attempted several methods to help young people going through cancer to conceive their own children.

    Ovarian tissue has been successfully removed, frozen and reimplanted after the cancer treatment is complete. Some women have had babies through IVF and naturally after using this method.

    Fertility specialists in the UK have also looked at developing a treatment to grow eggs from non-cancer sufferers, to allow them to delay motherhood.
    The first stage of the technique involves removing slivers of ovarian tissue through keyhole surgery. Although only a few millimetres wide, each sample would contain thousands of immature eggs.

    The procedure, which has been criticised by the pro-life charity Life, is seen as a low risk to women and has the added benefit of securing thousands of eggs rather than just a few.

    It can then be stored until a woman is ready to try for a baby. The procedure is expected to be offered to patients within five years.

    That's quite remarkable. It looks like sometime in the future human eggs could be grown from basic tissue from any person. People could go to a medical center and customize their babies, have it grown in a dedicated laboratory from nothing to full fledged baby. Then robotic humanoids could assist in raising it.

    But the question remains why raise humans at all (including cyborgs) when sentient machines start outperforming them.

    One small problem to overcome.

    They grow up to be five year olds.

    What do you mean?

    Also see the Singularity theory.

    The technological singularity is a theoretical future point that takes place during a period of unprecedented technological progress sometime after the creation of a Superintelligence.[1]


    Statistician I. J. Good first wrote of an "intelligence explosion," suggesting that if machines could even slightly surpass human intellect, they could improve their own designs in ways unforeseen by their designers, and thus recursively augment themselves into far greater intelligences. The first such improvements might be small, but as the machine became more intelligent it would become better at becoming more intelligent, which could lead to an exponential and quite sudden growth in intelligence.

    Potential dangers

    Superhuman intelligences may have goals inconsistent with human survival and prosperity. AI researcher Hugo de Garis suggests AIs may simply eliminate the human race, and humans would be powerless to stop them.
    Berglas (2008) argues that unlike man, a computer based intelligence is not tied to any particular body, which would give it a radically different world view. In particular, a software intelligence would essentially be immortal and so have no need to produce independent children that live on after it dies. It would thus have no evolutionary need for love.


    Other oft-cited dangers include those commonly associated with molecular nanotechnology and genetic engineering. These threats are major issues for both singularity advocates and critics, and were the subject of Bill Joy's Wired magazine article "Why the future doesn't need us" (Joy 2000).



    Bostrom (2002) discusses human extinction scenarios, and lists superintelligence as a possible cause:
    When we create the first superintelligent entity, we might make a mistake and give it goals that lead it to annihilate humankind, assuming its enormous intellectual advantage gives it the power to do so. For example, we could mistakenly elevate a subgoal to the status of a supergoal. We tell it to solve a mathematical problem, and it complies by turning all the matter in the solar system into a giant calculating device, in the process killing the person who asked the question.
