Introducing the new KNOWHEN® Saliva Fertility Monitor
Understanding your fertility cycle is a great step forward in planning a pregnancy. Now women can get extra help with a new KNOWHEN® Saliva Fertility Monitor.
This is a small handheld microscope that can be used to help determine when ovulation is taking place. The microscope is used to analysis a single drop of saliva. Approved by the FDA and clinically proven to offer 98% accuracy, this new product can help pinpoint the day of ovulation.
How does saliva sampling help to determine ovulation?
Just before ovulation there is an increase in the amount of the hormone oestrogen in the body. This coincides with a surge of luteinizing hormone (LH) and salinity. Saliva sampling can be used to identify elevated salts.
As the saliva sample dries, the salt crystallizes. When crystallized the salt resembles ‘fern’ shapes. The more developed and prominent these crystallized shapes, the higher the level of oestrogen in the body. This signals that ovulation is impending. The KNOWHEN® Saliva Fertility Monitor Ovulation Predictor helps to identify when ovulation is occurring.
How to use the KNOWHEN® Saliva Fertility Monitor
- Take off the lens cover and remove the housing
- In the morning before eating, drinking, or brushing your teeth or place a large saliva drop onto the provided glass
- Wait until the saliva is completely dry (around 15 minutes) and replace the lens housing.
- View the image by holding the monitor up to your eyes and compare it with the images on the provided chart. The image will indicate what stage you are in your ovulation cycle.
The result can be imputed into the provided mobile phone KNOWHEN® app. This is a personal ovulation daily test tracker that comes with the KNOWHEN® Saliva Fertility Monitor. It is designed to help you identify the best times to try and conceive based on predicted ovulation times.
How reliable is saliva sampling?
Every woman has a unique ovulation pattern and there will always be variations in the concentrations of salt within saliva. Analysing saliva samples can provide a good, general guideline. However, it’s really important to follow the instructions carefully and back this method of ovulation prediction with other techniques.
When assessing saliva, it’s very important to ensure that the sample is completely dry before analysing. The true pattern of salt crystalisation will not be apparent until the sample is totally dry. Assessing the sample too soon can lead to an inaccurate interpretation.
It can take a little while to get accustomed to analysing saliva samples. In some cases it may take a couple of cycles to recognise the signs of ovulation. However, with kits like the KNOWHEN® Saliva Fertility Monitor the accompanying chart provided a useful aid.
It’s recommended to back up saliva sample monitoring with other techniques that can help to determine ovulation. There are lots of other ways that you can calculate your most fertile days. Tracking your basal body temperature is one common method used to detect hormonal changes indicative of ovulation.
Use all the tools at your disposal!
At the end of the day, using all the proven methods to predict your most fertile days and having unprotected sex during this time will increase your chances to conceive. The KNOWHEN® Saliva Fertility Monitor is another tool that can help you start a family. Remember, it’s also very important to focus on a healthy diet and positive lifestyle choices when trying to fall pregnant and support the development of a healthy baby.
