What is the saliva fern test?

Your saliva crystalizes during your fertile days. Your body goes through different stages of your ovulation cycle. First the estrogen hormone levels increase and cause that saliva starts to crystalize. These saliva crystals resemble the shape of fern leaves and the whole procedure is called saliva fern test.

Using our high-quality microscope and app, you can detect these crystals in your dried saliva samples. Just try it!

How reliable is the saliva test?

Harvard Medical School studied the effectiveness of the saliva ovulation test combined with automated crystal detection in 2018. The Harvard researchers have concluded that the accuracy of the same solution as Babyndex is higher than 99%. Using this method, we detect estrogen hormone increases in a less intrusive and more affordable way than comparable urine or electrolyte tests. What is more, FDA has already approved saliva test for ovulation prediction, which is what Babyndex is also based upon.

What our customers say

I use an ovulation microscope because I was told that saliva test might work even with unstable cycles. I was not convinced at a first glance because I have small crystals almost every day, but the Babyndex app analyzes the level of crystalization and it really starts to increase a few days before ovulation. The app is easy to use, a bit too simple but this is still the only one for saliva fern test.

We were trying to get pregnant for years so I know how important it is to understand my body. I was using a saliva microscope already but Babyndex app takes it to a new level. I like how I don’t need to guess my own interpretation but can trust the app to do its job!

It is an excellent tool for easily and quickly detecting from saliva whether we have ovulation and when we are in our most fertile period. It greatly helps to achieve a desired pregnancy, which in my opinion is both faster and easier in this way than with various urine tests. It took me a while to learn and come up with how much saliva to put on the microscope and to wait patiently. Today, in the pre-ovulation period, the crystals are nicely outlined and, thanks to the application, it is easy to look back at any time how a certain cycle has developed. I have been using it for 3 months, but I would like to continue as well, I am confident that in the short term this too will be one of the foundations of our success and will bring the long-awaited result.

Babyndex might help you. During the fertile days, the structure of body mucus changes and dry saliva crystallizes. We have built an application to help you detect these saliva crystals. Plus, we thought it would be necessary to write about actionable tips on how to improve fertility and to reach your desired goals.
