OvuSense logo

OvuSense is different from anything else you may have heard of, or used previously to monitor your ovulation. That's because it measures Core Body Temperature using a specially designed sensor clinically proven in 2 trials and 6 peer reviewed publications.

Clinical studies show that 70% of women don’t ovulate in the middle of their cycle, and you can ovulate at a different time from cycle to cycle, even if your cycles are always the same length [1]. If you've been trying for some time and haven't managed to conceive yet, that could well be the reason why. The good news is by providing core temperature data in real time, throughout each cycle, OvuSense solves the issues this normal variability causes with monitoring your ovulation.

Fertility monitoring methods such as fertility apps, Basal Body Temperature (BBT), wrist worn devices, and skin temperature measurement are shown by clinical data to be inaccurate with this normal variability [2]. That's simply because they rely on data from previous cycles to predict when ovulation will occur in a following cycle. If you don’t ovulate in the middle of your cycle or your timing of ovulation is at all variable, then the fertile prediction is likely to be incorrect.

OvuSense was developed to provide the same benefit as urine based luteinizing hormone tests (OPKs) by predicting the onset of ovulation up to one day in advance in real time in each cycle. However, it does so with greater accuracy [3], and crucially, OPKs also don't work when your ovulation timing changes due common hormone issues [4].

Endorsed by doctors and fertility specialists, and able to work whatever is happening in your cycle, why use anything else? OvuSense is helping women all over the world just like you to take control of their fertility [3].
