How does PCOS affect fertility?

If you have PCOS (polycystic ovarian syndrome) your cycles are likely to be longer than 30 days and often irregular. You may menstruate infrequently, making it impossible to know exactly when ovulation occurs. If you do ovulate, it's quite commonly late in your cycle. We created OvuSense just for women like who want to know exactly what is going on and take back control of their fertility.

How can OvuSense help?

OvuSense is different from anything else you may have heard of, or used previously to track your ovulation. That's because it measures core body temperature using a specially designed sensor proven in over 50,000 cycles use, and as a result is clinically proven to work if you have PCOS or irregular cycles.

OvuSense works by using a vaginal sensor (the size of a tampon) to take your core body temperature every five minutes while you sleep, to build up a complete and accurate picture of your fertility pattern. In the morning, you simply download your data to your smartphone via the OvuSense app.

It works right away – from cycle one, there is no waiting and ‘learning’ your cycle patterns unlike other products. The real time prediction will provide you with a 24 hour advance notice of ovulation based on your current cycle data, so you don't have to rely on information from your previous cycle as with other temperature devices to know when you're ovulating.

You can use OvuSense alongside fertility medications and supplements to track if they are working. OvuSense is endorsed by Fertility specialists, and has a clinically proven accuracy of 99% for confirming when you ovulated , helping women just like you to take back control.

OvuSense is as easy as....


Insert the sensor in your vagina overnight. It measures your core temperature every 5 minutes. No radio waves are transmitted from within your body, so OvuSense is completely safe to use.


In the morning, remove the sensor, wash it and download its data to the OvuSense App. OvuSense uploads data to a secure cloud database, keeping your information safe.


OvuSense provides live updates predicting ovulation up to 24 hours in advance using your current cycle data. This helps you time your conception during each individual cycle, even if you have irregular ovulation timing.


OvuSense then confirms ovulation with 99% clinically-proven accuracy, helping you understand your cycle better and track the effect of any medication you may be taking.

"I am pregnant with my
second OvuSense baby.
We were trying for 8+
years before that.”

“Finally pregnant! I have adrenal PCOS, a blocked right tube, and crazy irregular cycles. I’m also at high risk for miscarriage. It took a year of trying BUT, I do have to thank Ovusense. It helped me identify what symptoms I had during ovulation (like breast tenderness that I assumed was a PMS symptom) which allowed me to pinpoint when I was ovulating. I will be surprising my husband tonight when he gets home. I’m still in shock! Good luck to everyone. I hope this one sticks!”
