A cut-price test that could dramatically increase the chances of having a healthy baby through IVF could be available within 18 months. Oxford University researchers say their test could ‘revolutionise’ the treatment as it is half the price of existing tests and may be just as effective.
It may be cheap enough for use by the Health Service. And, unlike existing tests, it does not involve the potentially risky step of taking a sample of cells from the egg or fledgling embryo, making it safer and more ethically acceptable.
Instead, it works by analysing a ‘cloud’ of cells that nurture and feed the egg. These are normally thrown away in IVF treatment but fertility doctors Dagan Wells and Elpida Fragouli believe they hold important clues to the health of the egg.
Keeping and analysing these cells could help clinics select the best eggs for fertility treatment. It should also spare would-be parents the emotional and financial heartache of going through repeated unsuccessful IVF treatments. Analysing these ‘cloud’, or cumulous, cells is also likely to be much cheaper at £1,000 or less compared with the £2,000 cost of other techniques, bringing the technology within range of many more couples.
Despite IVF’s reputation as an insurance policy, the treatment works in less than a quarter of cases, and many of the failures are because of problems with the eggs’ chromosomes. There are already several ways of checking the chromosomes, but they require a small sample from the egg or embryo and so are not completely without risk to the unborn child.
The cumulous cells, however, can be studied without harming the egg. These cells grow and mature with the egg and so any problems that damage the egg, such as a poor blood supply, should also show up in the cells. The doctors have carried out a small-scale study that has shown that certain genes being over or under-active in the cumulous cells is a sign of abnormal eggs.
Calculations suggest that using the technique to pick out the healthiest eggs would boost a woman’s odds of having a baby. Existing tests can double or triple the odds of IVF success, and it is hoped the new test will be just as good.
Dr Wells said: ‘The number of patients we looked at is very small. This is very much a work in progress, but there is good reason for optimism at this point.’
A larger-scale study is planned, and if that goes well the technique could be trialled on women for the first time in the summer of 2012. If it proves to be safe and effective, it could be in widespread use early in 2013.

IVF not needed for many infertile couples - DuoFertility study shows
A new study published in European Obstetrics & Gynaecology shows that just six months using the DuoFertility monitor and service gives the same chance of pregnancy as a cycle of in-vitro fertilisation (IVF) for many infertile couples. This study demonstrates that there is a viable non-invasive, drug-free alternative to IVF for thousands of couples, with the potential to save them (and the NHS) millions of pounds each year.
The paper is the first peer-reviewed publication of clinical pregnancy rates using the new DuoFertility product and service. Lead author, Dr. Oriane Chausiaux said “The results show that for couples suffering from unexplained infertility as well as a variety of other factors, twelve months using DuoFertility yields a higher clinical pregnancy rate than a cycle of IVF.” Not only is IVF invasive for the woman and demeaning for the man, but for many couples it is a procedure needlessly costing the NHS, or the couple themselves, thousands of pounds. A typical cycle of IVF in the private sector costs £7,000 all up. By comparison the DuoFertility program offers a year of monitoring and support for £500 - and it comes with a 12-month money-back pregnancy guarantee.
The publication coincides with the 200th reported pregnancy by users of DuoFertility, which was celebrated at the weekend with a party hosted by medical personality Dr. Miriam Stoppard. Dr. Stoppard, addressing the assembled parents and parents-to-be, said "[it is] the first product or service that I have seen in this arena which truly wraps around all of the needs of the couple, from the medical monitoring, to the review of this data by experts, and then the all-important emotional support that is provided."..."The results of the scientific studies on pregnancy rate are very encouraging, but do need to be followed up with live birth rates, and I look forward to seeing further research."
The authors of the study caution that although non-invasive and drug-free, DuoFertility is not suitable for all couples. Dr. Husheer, inventor of DuoFertility explained “although DuoFertility is suitable for around 80% of infertile couples, there are some couples with medically identified conditions that prevent natural conception, such as a woman with two blocked fallopian tubes. In these cases IVF is absolutely the right thing to do, enabling conception where it was previously a physical impossibility.”
About Cambridge Temperature Concepts Cambridge Temperature Concepts Limited (CTC) has developed a new kind of wireless physiological monitor, which measures body temperature, heat flow and movement with unprecedented resolution. The first application (DuoFertility) is in conception assistance for couples suffering infertility, however work is underway in areas as diverse as sleep quality monitoring, hypoglycemia detection, infection control and a range of veterinary applications. DuoFertility is a non-invasive, easy-to-use female fertility monitor. It is the most natural, convenient, and precise way of maximising the chances of getting pregnant.
CTC was founded by graduate students at the University of Cambridge in, winning business competitions at collegiate, university, regional and national levels prior to Angel funding. Less than 18 months later, the DuoFertility product had progressed from sheet-of-paper through medical device approvals, production prototype, Europe-wide trial, and had gained first direct-to-consumer sales.
