    new smartwatch alerts women when they conceive

    the traditional home pregnancy test could soon be obsolete, scientists have said as they announced a new smartwatch system that alerts women when they conceive.
    Trials in Switzerland have allowed researchers to identify for the first time a package of minute physiological changes, detectable by existing hardware, that take place when pregnancy starts.
    They are now building an algorithm which learns the individual wearer’s personal characteristics so it can not only signal the start of a pregnancy but also highlight the best windows in which to try for a baby.

    The technology promises to allow women hoping to conceive to do away with the morning ritual of a home pregnancy test, which assesses levels of human Chorionic Gonadotropin in urine.

    The team behind the Ava bracelet, which is expected to cost around £200, plan to begin real-world tests of the system before the end of the year.

    Presenting their research at the American Society for Reproductive Medicine annual congress in Texas, they described the subtle changes in skin temperature, breathing rate, pulse and heart rate variability that occur when a women conceives.
    They found a pulse variation of just 2.1 beats per minutes, as well as a 0.2C change in skin temperature was indicative of the onset of pregnancy, probably due to hormonal changes involving progesterone and oestrogen.
    The smartwatch is able to detect pregnancy around a week after conception, the same as the most sensitive pregnancy test. In the future, it may be able to detect conception sooner, the developers believe. 
    Mohaned Shilaih, senior researcher at University Hospital Zurich, said: “Rather than waking up every morning and trying to pee on a stick to detect the rise in hCG you would simply have the bracelet worn both night and day.”
    He described the standard method as “physiologically tedious” for women, adding: “This would partly take away this kind of pressure.”
    The Zurich researchers said the machine learning system would be continuously developed to monitor women during pregnancy, potentially providing early warning of serious conditions such as preeclampsia, which can force doctors to induce premature birth.
    HCG was first discovered to be linked to the fertilisation of eggs in the 1930s, however it was not until the 1970s that home testing kits became widely available.
