How does PCOS affect fertility?

If you have Polycystic Ovarian Syndrome the timing of your ovulation is likely to vary from one cycle to the next. You may also have infrequent periods, making it impossible to know exactly when ovulation occurs. However, clinical studies show that in fact 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]. So, if you've been diagnosed with PCOS or think you may have variable ovulation, you're in the majority. We created OvuSense just for women like you 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 continuous Core Body Temperature using a specially designed sensor clinically proven in 2 trials and 6 clinical publications.

Measuring continuous Core Body Temperature (cCBT) enables OvuSense to track daily fluctuations in your progesterone - the hormone released during the process of ovulation, that also needs to be sustained in the second half of your cycle to help you conceive. This progesterone pattern is unique to you, and OvuSense uses it to predict your ovulation up to 24 hours in advance using current cycle data, confirm the exact date of ovulation, and monitor your individual pattern from cycle to cycle - meaning it works even if you have irregular ovulation as a result of PCOS or other issues.

If you purchase a subscription to the additional OvuSense® Pro portal, your doctor can then screen remotely for ovulatory issues and track if medications, supplements and lifestyle changes are helping with your ovulation timing and bringing your cycles under greater control.

How can I improve my chances of getting pregnant?

Wherever you are in your fertility journey, you need two key pieces of information, particularly if you have variable ovulation or an ovulatory issue like PCOS:

Question 1) When did I ovulate last cycle?
To know whether you are ovulating or not, and to help understand the length of your luteal phase.

Question 2) When am I going to ovulate this cycle?
You can only know this for sure by using the current cycle data.

By providing Core Body Temperature data in real time, throughout each cycle, OvuSense answers both these questions and helps you work out what's happening more generally with your cycle. It's the only home based solution that does this.

What's the difference with fertility tracker apps, and other temperature devices?

Fertility monitoring methods such as Fertility Tracker Apps, Basal Body Temperature (BBT), fertility bracelet devices, and skin temperature measurement are shown by clinical data to be inaccurate because of the way in which they predict [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.

So they can answer Question 1, but not Question 2.

What's the difference with urine tests?

Urine based luteinizing hormone tests (OPKs) and urine monitoring devices (OPMs) are useful when you're starting out to try and understanding when you might ovulate in this current cycle. You'll need to use 2 strips a day around 10 to 15 days in your cycle to get a reliable result.

With this they can answer Question 2, but they can't answer Question 1.

It's also essential to know that OPKs and OPMs don't work if you have ovulatory issues [3]. That's because your luteinizing hormone (LH) doesn't rise as expected before ovulation if you've got an ovulatory issue - you may receive false positives, particularly early in your cycle, or never receive a positive result. Even if your monitor shows you the level of LH and employs AI it cannot help you conceive if ovulation doesn't follow the rise of LH within 48 hours.

OvuSense was developed to provide the same benefit as OPKs and OPMs 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 [4], and crucially because it is tracking the level of progesterone using Core Body Temperature it's able to always reliably track when ovulation is happening even if you have an ovulatory issue.

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 [4].
