DuoFertility Decodes Messages Between Armpit, Ovaries

Cambridge Temperature Concepts Ltd. received 510(k) approval for their DuoFertility ovulation Monitor. The DuoFertility monitor has been featured previously onMedgadget and comprises a wearable sensor and reader unit for measuring ovulation patterns. The sensor is worn under the armpit and measures subtle changes in basal body temperature which is indicative of ovulation. The reader wirelessly receives the sensor data and predicts when you are most likely to become pregnant up to six days in advance. A number of additional parameters can also be entered into the reader unit to improve the prediction quality. The recorded data can be visualized by connecting the reader unit to a PC, as shown in the video below.

The DuoFertility has been commercially available in Europe since 2009 and was the subject of aresearch paper published last year which demonstrated its efficacy in some couples eligible for IVF.

From the product website:

The study followed the first 500 couples using DuoFertility from launch in 2009, including 242 who qualified for IVF/ICSI treatment, of whom 90 had previously had the procedure. The one-year clinical pregnancy rate for those who qualified for IVF was 39%, which is higher than either the UK or EU clinical pregnancy rates for a cycle of IVF (26% and 28% respectively), whilst the corresponding rate for those who had already been through a cycle of IVF/ICSI was 28%.

The study included couples with unexplained infertility, as well as those with mild to moderate male and female factor infertility. This accounts for approximately 80% of all infertile couples, and half of all IVF patients.

At the Future Health Mission 2011 in San Francisco last week, we were offered a chance to check out some of the latest and most promising medtech startups from the United Kingdom, who came for a tour of Silicon Valley.
Here’s one technology that impressed us a lot. DuoFertility is an ovulation pattern temperature monitor from Cambridge Temperature Concepts Ltd. The DuoFertility technology wasprofiled by us back in 2008 when it was in prototype stage. Now it is a fully developed device that has an auxiliary temperature monitoring patch and a receptacle that downloads temperature data from the patch and sends it to a service center. The idea is to use the temperature variations of a woman to extrapolate the best day(s) for her to conceive. According to the company’s CEO and founder Dr Shamus Husheer, the device is already selling quite well in emergent markets such as Middle East and Asia, and is on its way to wider use in Europe. And, of course, the company is hoping to obtain US FDA approval sometime in the near future.

The system is based on a sophisticated version of the body basal temperature (BBT?) measurement method (the small upward shift in basal body temperature which is associated with ovulation). The system identifies when you are most likely to get pregnant, up to six days in advance. This gives you plenty of time to plan intercourse for the best time of the month.
Temperature measurements are made automatically up to 20,000 times per day by the DuoFertility sensor. In addition, personal fertility related data you provide such as menstruation? dates, ovulation pain, etc are also added into the fertility analysis to give you the most accurate predictions possible.
