Internal device 99% accurate in sensing ovulation

A “GAME-CHANGING” device that boosts the chances of becoming pregnant by accurately sensing when they will be most fertile has been developed by scientists. For the first time, women can predict when they will ovulate, rather than when ovulation has begun.

The internal device, created by scientists from Bristol University, provides the most accurate measure yet of core body temperature, a clear indication of fertility.

At present, kits exist that measure temperature via the mouth or skin. But this £129 (R2 310) tampon-shaped device sits in the vagina and records subtle changes every five minutes to build an accurate picture of a cycle, downloaded via the OvuSense app in the morning once the sensor has been removed.

It gives 24 hours’ notice of ovulation, along with a fourday ovulation window – clinical tests suggest it is 99 percent accurate.

Professor Toby Knowles said: “We’re proud to have played a part in the development of such an advanced and reliable product… that has helped so many women fall pregnant.” – Mail On Sunday
