The Science Behind OvuSense

OvuSense is a class 2 medical device, and is backed by a decade of science, research and evidence. It is clinically proven in trials to increase the likelihood of getting pregnant. It all starts with knowing your body, knowing your cycle, to give you the best chance of conceiving.

OvuSense fertility monitor is able to confirm ovulation with 99% accuracy. it achieves this using the patented OvuCore sensor, which intelligently measures overnight continuous Core Body Temperature (cCBT). cCBT shows you exactly what is happening to progesterone during your cycle. When progesterone rises, your cCBT rises, and as progesterone is released during ovulation OvuSense is able to measure that rise to tell you when you ovulated. Not only that but the OvuCore sensor is able to see when ovulation is going to happen during the cycle, so it will predict ovulation up to 24 hours in advance. That's particularly helpful if you have variable ovulation timing

At the start of your next cycle, OvuSense provides you with an 8 day fertile window, compared to other methods which can only show 3-6 days. So, OvuSense maximizes your chance of pregnancy.

The best fertility monitor for irregular cycles

Our patent protected monitor has also been clinically proven to offer women with irregular cycles the same level of accuracy as those on regular cycles. It is important to know that urine strips, also know as ovulation predictor kits, sometimes just don't work if you have irregular cycles.

Women suffering with polycystic ovarian syndrome (PCOS), diminished ovarian reserve or thyroid issues are most likely to experience irregular cycles, but there are also many women with PCOS and other issues who have a regular cycle but irregular ovulation. OvuSense makes tracking these cycles simple and highly accurate, giving you the best chance of conception out of any product available on the market if you have an ovulatory problem due to one of these issues.

OvuSense tracks the direct effect of progesterone on the ovaries, and that's why it is able to predict and confirm ovulation with such a high degree of success.

"OvuSense was invaluable"

I have PCOS, hypothyroid and Hashimoto’s. I started using OvuSense after many previous years of TTC unsuccessfully and we conceived our miracle baby on cycle 12 . The information that I learned about my cycle by using OvuSense was invaluable.


"OvuSense gave me hope"

I started by using ovulation strips and that was a waste of money, I never had a static smiley face. When I got OvuSense, I was already trying for 7 months with no luck at all but OvuSense gave me hope because it showed I WAS ovulating. Now I’m pregnant with my baby boy. Lisa
