A complete support system to maximise your chances of conception

"Far more accurate than any current system and could save the NHS - and individual couples - a fortune on unnecessary fertility treatment."


Get pregnant in 12 months - or your money back!

Your doctor will expect you to have tried for a baby for at least a year before considering other options. And even then you will have to wait for referral to see a fertility expert. Rather than wait for months on end, you could take advantage of DuoFertility’s money back offer. If you use Duofertility for 12 months and don’t get pregnant – we’ll give you your money back.

But using DuoFertility also gives you so much more through that year. DuoFertility will also be a great source of comfort and reassurance because it not only maximises your chances of conceiving – it provides you with your own personal fertility coach who will be able to counsel and advise you over the telephone and by email in the comfort of your own home. Even if you do not fall pregnant, you’ll enjoy the reassurance of knowing your fertility history and the confidence of seeing you are ovulating. You’ll also have a comprehensive fertility report to take to your doctor when the time comes.

DuoFertility allows you to pinpoint fertile days up to a week in advance, confirms when you are ovulating and gives you the reassurance of your very own PhD-qualifed fertility coach working with you to maximise your chances of conception? each and every month.

  • Unsurpassed accuracy

    The DuoFertility fertility monitor has been described in the Daily Mail as being ‘far more accurate than any current system’. The BBT measurement method used by DuoFertility has been scientifically proven to identify your most fertile days with 99% accuracy. It is the only method that has been scientifically proven to confirm ovulation.

    Unlike manual BBT measurements which are prone to human error, DuoFertility measures your temperature automatically throughout the day and night, eliminating the potential for error. Unlike traditional BBT thermometers, DuoFertility’s measurements are not affected by outside factors such as interrupted sleep patterns, stress, or alcohol consumption.

    DuoFertility is the only fertility monitor on the market which allows you to enter in other personal fertility parameters, such as the quality of your cervical mucus or the position of your cervix. Studies have shown that including this additional information increases the accuracy of detecting your fertile days to 99.7%.

  • Totally natural

    DuoFertility is a safe and natural alternative to expensive fertility treatments. It is completely non-invasive and has no associated side effects. Trying to get pregnant no longer has to involve doctors and medication – just you, your partner, and DuoFertility.

  • Absolute convenience

    We understand how demoralising it can be to wake up early every day to pee on a stick or take manual temperature measurements. With DuoFertility, there are no manual temperature measurements, no early morning wake-ups, and no peeing on a stick. All you have to do is wear the DuoFertility sensor under your arm and DuoFertility will do the work for you. You can monitor your fertility levels on the hand-held reader wherever and whenever it is most convenient for you. You also have the option of looking at your fertility charts in greater detail on your PC.

  • DuoFertility is for you and your partner

    Just like thinking about having a baby is a big decision for you and your partner, so buying DuoFertility is a decision both of you should make. Knowing your fertile days up to a week in advance can be very reassuring for both of you and allows you and your partner time to plan romantic night well ahead. Knowing your fertile days isn’t just reassuring – it helps you feel that you are making love, rather than simply making a baby to order that can sometimes be the case with other methods of detecting fertility. You’ll also enjoy the benefit of seeing your full cycle history on-screen to discuss with one another – and enjoy the reassurance of fertility expert support by phone and email for a whole year..
