Fertility sensor helps women identify ovulation window

Unlike other fertility trackers, OvuSense, a Class 2 registered medical device, gives 24 hours' advance notice of ovulation, along with a four day ovulation window, which has been clinically proven to be correct 99 per cent of the time.

The technology was developed by Dr Andy Butterworth and Professor Toby Knowles, from the Faculty of Health Sciences at the University of Bristol, and has since been licenced by the University to their spin-out company Fertility Focus, which was founded in 2006 with Bristol alumnus Michael James.

Professor Knowles said: "We're very proud to have played a part in the development of such an advanced and reliable product that really has produced a step-change in the accuracy with which women's fertility can be monitored, and that has already helped so many women to become pregnant."

The sensor fits comfortably into a woman's vagina, similar to a tampon, and is worn while she sleeps.

It takes a core body temperature reading every five minutes to build-up an accurate picture of the woman's cycle, which is downloaded via the OvuSense app in the morning once the sensor has been removed.

Sue Sundstrom, Head of Commercialisation at the University of Bristol, said: "It's really gratifying to see University research move from the lab and into a real-life application, especially given the positive impact it will have on such an important and distressing problem, changing women's lives for the better."

The OvuSense app for iOS has been launched in the UK and US, with an Android version available at the end of August.

OvuSense works even if there are medical conditions that impact hormone levels, and since OvuSense automatically finds when a user ovulates, in real time, there is no guessing when to start testing each month.

OvuSense is unique, unlike any other fertility monitor or fertility App on the market:

• Clinically proven: OvuSense is the most advanced cycle monitoring system you can buy - clinically proven in over 6,000 cycles of use;
• Real time 24 hour advance ovulation prediction: Unlike any other monitor, OvuSense provides a day's advance notice of when you are going to ovulate in real time along with your 4 day ovulation window - proven in clinical analysis to be correct 96% of the time;
• 8 day fertile window: In addition, at the start of each cycle OvuSense provides a full 8 day fertile window - these features help you take back control of your planning for pregnancy;
• Fully certified: OvuSense is a fully regulated medical device and complies with all the necessary certifications for the countries in which it is available - CE mark in Europe, FDA 510(k) in USA, CMDCAS in Canada, TGA in Australia;
• 'Core temperature' technology: OvuSense's 99% accurate patented technology, and why other products produce an incorrect result in at least one in every five cycles.

OvuSense runs and manages several closed support groups on Facebook with the largest one called PCOS FERTILITY SUPPORT. PCOS Fertility Support Group has grown to be the largest PCOS trying to conceive support group on Facebook with over 10K members.
