Ava bracelet confirms ovulation

Ava has developed a bracelet that supports women in determining their fertile window. It measures various physiological parameters, including pulse rate, skin temperature, heart rate variability, breathing, circulation and body heat loss. The data is transferred to the user’s mobile phone and evaluated. This enables women to keep track of their fertility window.

Now, the startup from the Greater Zurich Area has added a new feature to its bracelet, as it reported in a press release. The new tracker can detect a biphasic pattern during a woman’s cycle. In a biphasic pattern, some of the physiological parameters including body temperature and pulse rate increase in response to the rise in progesterone after ovulation. This new function will inform women whether ovulation has occurred.

According to Ava, up to 12 per cent of women actually have anovulatory cycles, i.e., cycles without an ovulation. Many Ava users typically want to know if they have ovulated at all, as this is a key factor in getting pregnant. Ava reveals it is the only device available today that can detect a biphasic pattern not just based on temperature, but also on other parameters such as pulse rate.

Furthermore, Ava announces that it has launched a new clinical trial in collaboration the University Hospital Zurich. This will study the potential use of the Ava bracelet in detecting the onset of infection during pregnancy. Early recognition of such infections would ultimately enable earlier and better therapy and reduce health risks for mother and child.

Ava was founded in Switzerland in 2014 and has operations in Zurich and San Francisco.
