Ava has increasingly become ambitious as to what's possible with a fertility wearable. The company's original goal was to simply help tell users when they're most likely to get pregnant. It's even launched a study into whether its devices could actually detect pregnancy.

Now it's adding a new feature to its Ava bracelet that will analyze data from the body in order to detect if you've ovulated.

It works by detecting an increase in skin temperature and pulse rate that comes as a result of the hormone progesterone being released to prep the uterus for pregnancy. Ava's device will then tell you that you're in your biphasic pattern.

But wait, you might be wondering, don't women ovulate during their cycle no matter what? Well, it turns out that's not the case. According to Ava, 12% of women have cycles with no ovulation. If you're using Ava's fertility wearable to track your cycle, and it happens that you didn't ovulate, then you're not exactly fertile.

So this makes it much easier for Ava users to tell if they're fertile. At the same time, the University of Zurich has launched a study to look into whether Ava's wearables can be used to detect infections during pregnancy.

Infection during pregnancy can affect both the mother and child, and it can lead to premature delivery. If caught early, however, doctors can introduce therapy and treatments which can reduce the risks.

    I'd like to see good data comparing this to the sympto-thermal method done the usual way, with oral, vaginal or rectal temperatures. The wrist is not meant to be a good place for detecting the tiny rise in temperature required to confirm ovulation, and even the armpit hasn't done well. If it turns out that reliable temperature data can be gained from the wrist, there will be a lot of possibilities. They won't want to get it wrong, however, because if they give people incorrect advice on avoiding pregnancy, they will be sued to high heaven.
