[H2] How OvuSense Works in 3 Easy Steps

[H4] 1. Track

[IMG: OvuCore insertion]

Wear the OvuSense sensor overnight to take continuous Core Body Temperature (cCBT) measurements in the vagina using a thermistor with a resolution of 0.003°C.

[H4] 2. Analyze

[IMG: OvuSense App data updating]

The OvuSense algorithm intelligently filters and smooths this data to create a clear curve, providing the most accurate representation of your cycle.

[H4] 3. Act

[IMG: OvuSense Pro]

The app confirms ovulation with 99% accuracy, giving you the confidence to plan for pregnancy or regulate your cycle with or without assistance from a Doctor.

Unlike skin-worn devices or urine strips, OvuSense’s patented core body temperature technology isn't affected by external factors. By measuring precise changes in progesterone activity based on temperature fluctuations measured internally, OvuSense delivers the truest representation of the continuous changes in your cycle.

[H2] Detecting the Patterns That Matter

OvuSense now flags eight unique cycle patterns directly within the app to help reveal hidden clues about your fertility health.

[IMG: OvuSense Cycle Flags]

Advanced cycle pattern analysis, only visible with OvuSense.

Using patented core body temperature technology and advanced algorithms, OvuSense detects subtle changes in your cycle
and identifies patterns that may indicate underlying issues.

These patterns can explain why conception may be taking
longer than expected —especially helpful if you have PCOS or irregular periods— helping you take informed steps toward better reproductive health.

OvuSense empowers you with actionable insights, helping you advocate for better care and start meaningful conversations with your doctor.

[H3] OvuFirst

[H4] How does it work?

The OvuFirst sensor works with the OvuSense App. You wear it on your skin overnight, using our specially designed armband to hold it under the armpit, or wristband to hold it on the underside of your wrist.
[H4] What are the benefits?

The patent protected OvuFirst Sensor solves some of these issues caused by other methods by taking multiple overnight skin temperature measurements using an identical set of components to our revolutionary patent protected OvuCore Sensor technology: it has a thermistor with a resolution of 0.003 degrees Celsius [a], the OvuFirst algorithm intelligently filters the data avoiding the problems caused by 'dropouts' experienced by other skin based monitors, and then applies smoothing techniques to provide the clearest possible curve provided by a skin measuring method. Using the OvuFirst Sensor, your OvuSense App confirms the ovulation window with suggested date of ovulation with over 90% accuracy [b, c].

Added to the accuracy of skin temperature measurement, there's no messy urine strips, no confusing charts with multiple parameters, and no need to remember to test.

[H4] Clinical Publications

[a] The measuring resolution of a thermometer is the step between each temperature reading - a resolution of a normal 0.1 degree Celsius means a reading may be wrong by as much as 0.099 degrees Celsius, or in other words there are only 3 steps between a wrong and right ovulation result of 0.3 degrees Celsius rise, whereas 0.003 degrees resolution provides 100 steps.

[b] The accuracy measures how many positive and absent ovulations the device confirms correctly.

[c] The clinical proof for OvuFirst is provided by a side by side study of the OvuFirst sensor with vaginal core body temperature measured using the OvuCore sensor (2022) - Hurst BS, Davies K (2022) Novel Technique for Confirmation of the Day of Ovulation and Prediction of Ovulation. Bioeng. Biotechnol., 04 March 2022..

[H3] OvuSense

[H4] How does it work?

The OvuCore sensor works with the OvuSense App. OvuCore is similar in size to a tampon and is placed in your vagina overnight. It's proven easy to use and comfortable to wear in clinical publications and over 235,000 cycles of use. [a]
[H4] What are the benefits?

The patent protected OvuCore Sensor technology solves the issues caused by other methods by taking multiple overnight continuous Core Body Temperature (cCBT) measurements in the vagina using a thermistor with a resolution of 0.003 degrees Celsius [b], the OvuSense algorithm intelligently filters the data, and then applies smoothing techniques to provide a clear curve and the truest representation of the action of progesterone on the ovaries. Using the OvuCore Sensor, your OvuSense App confirms the date of ovulation with 99% accuracy [c][e]. Unlike the other methods it is also able to predict ovulation in real time - the published literature shows it does this with an accuracy of 89% and a positive predictive value of 96% [d][e].

[H4] Clinical Publications

[a] The comfort and ease of use of OvuCore is documented in the following clinical paper:
Papaioannou S, Aslam M (2013) User’s acceptability of Ovusense: a novel vaginal temperature sensor for prediction of the fertile period. J Obstet Gynaecol 33:705–9.
.

[b] The measuring resolution of a thermometer is the step between each temperature reading - a resolution of a normal 0.1 degree Celsius means a reading may be wrong by as much as 0.099 degrees Celsius, or in other words there are only 3 steps between a wrong and right ovulation result of 0.3 degrees Celsius rise, whereas 0.003 degrees resolution provides 100 steps.

[c] The accuracy measures how many positive and absent ovulations the device confirms correctly.

[d] The positive predictive value measures how many of the real time predicted ovulations OvuSense gets right.

[e] The accuracy of ovulation confirmation by OvuSense is based on the data set originally published at the 2013 ASRM meeting as a quality index: Papaioannou S, Aslam M (2013), and developed in the key publication outlining the accuracy and positive predictive value of advance prediction of ovulation shown at the 2014 ESHRE meeting: Papaioannou S, Delkos D, Pardey J (2014).

[H3] Fertility Tracker Apps

[H4] How do they work?

Fertility Tracker Apps (FTAs) use the calendar based method of tracking. You input the dates of your period and the app will calculate your ovulation based on the assumption that you have 'middle of the month' ovulation. Some have more sophisticated algorithms which accept manually entered oral temperatures, or Ovulation Predictor Kit (Luteinizing Hormone) test results.
[H4] How close will the results be compared to OvuSense?

Even though Fertility Tracker Apps (FTAs) sometimes allow you to enter information other than just your period dates, they are not able to pinpoint the date of ovulation with useful accuracy because they are based on the assumption that all women have very regular cycles with ovulation that occurs in the 'middle of the month' Of all the methods for looking at your ovulation you need to know that FTAs are the least reliable, and you should really ignore the results they produce if you're struggling to conceive.
[H4] What are the benefits?

Fertility apps are convenient and a handy way of tracking the basic information in your cycle. They help you stay organised and often feature useful extra information to help with conception and pregnancy.
[H4] What are the drawbacks?

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]. A recent study into several fertility apps concluded 'as a result of the physiological variations of the menstrual cycle length and ovulation day, the fertile window cannot be predicted easily, and it has to be determined during the ongoing cycle. Therefore, to help couples wishing to conceive, apps based on data from previous cycles alone are not suitable to indicate the most fertile days' [2]. Another recent study concluded 'accuracy of ovulation prediction [using previous cycle data] was no better than 21%' [3]. Other studies have drawn similar conclusions [4].

[H3] Basal Body Temperature (BBT)

[H4] How does it work?

Long established in the clinical literature [1], the BBT method aims to help detect the date of ovulation in a cycle by taking the basal (lowest) temperature first thing on waking with an oral thermometer, and then charting the change in this daily temperature throughout the month to determine the date of ovulation. It can also be used if you have regular ovulation for predicting the fertile window in the next cycle. Because a rise in temperature is associated with the release of progesterone which occurs during ovulation, a predictable pattern emerges for most women which can help confirm ovulation took place over a number of cycles.
[H4] How close will the results be compared to OvuSense?

Even though the Basal Body Temperature (BBT) method uses temperature as a basis for confirming if ovulation took place, it relies on very different measuring technology from the patented protected system used by OvuSense. Oral thermometers only have an accuracy of around 0.1 degrees Celsius [a] so are not easily able to detect the 0.3 degree rise associated with ovulation with accuracy. Even if you type the values you get with your thermometer into a Fertility Tracker App they are likely to give a different ovulation result from OvuSense. You should also be aware that a vaginal temperature measured using the OvuCore Sensor is generally up to two degrees Celsius higher than temperature readings taken in the mouth, and higher still than external temperature readings such as those taken under the armpit or on the wrist. Lastly, OvuSense uses proprietary algorithms to detect ovulation, so it can produce very different results even with similar looking temperature curves.
[H4] What are the benefits?

BBT is a relatively cheap and easy way to track your temperatures and a number of apps are now available which combine the idea of a single oral temperature with automatic charting. It is more effective if combined with cervical mucus tracking.
[H4] What are the drawbacks?

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 [2]. As a result because BBT relies on predicting the fertile window based on past cycle data, it's of little practical use if you don't ovulate at the same time each month. With or without an app to help, BBT is unable to help predict ovulation using the current cycle data. Again, even with an app, some users find th
