A sensor bracelet which uses technology to precisely detect the fertile days during a woman’s monthly cycle in real time has been credited with its first birth.
Worn only at night while sleeping, the Ava fertility bracelet measures nine physiological parameters including pulse rate, breathing rate, heart rate variability, temperature that, in combination, help indicate a rise in reproductive hormones estradiol and progesterone. The impact of the rise of these hormones on the physiological parameters is used to detect a 5.3-day fertile window in a woman’s cycle. Because users simply wear the Ava bracelet at night and sync it with the Ava app in the morning, they avoid the hassles, mess and invasiveness of other fertility tracking methods like ovulation strips and BBT thermometers.
Classed in the US as an FDA Class 1 medical device, the Ava bracelet was proven in a recently concluded clinical study at the University Hospital of Zurich to detect an average of 5.3 fertile days per cycle – in real time – with 89 per cent accuracy.
This month, Ava’s Swiss founders Pascal Koenig, Philipp Tholen, Peter Stein and Lea von Bidder, have welcomed the first Ava baby conceived with the aid of the technology. Ava user Lizzie McGee, 32, and her husband, Sam, 31, welcomed son Jace McGee, on July 11, becoming the first confirmed “Ava baby” born since the bracelet’s official consumer debut.
Lizzie, a hairstylist in St George, Utah, found out about Ava after struggling for more than a year to get pregnant with her second child: “The experience of conceiving our first child was really difficult and stressful on our marriage, and I didn’t want to go through the same thing again with our second,” said McGee, who conceived Jace after wearing Ava for three months.
Lea von Bidder says secondary infertility is much more common than many people realise, “especially in cases where a couple has started their family later in life because it’s widely known that fertility decreases as maternal age increases”.
“Ava helps women optimise their chances of conception at any age by identifying in real time her full fertile window, not just the day of ovulation,” she said.
Since its consumer launch in August 2016, the Ava fertility tracking bracelet has helped more than 500 women conceive.
The Ava bracelet, which received The Bump “Best of Baby Tech CES 2017” award for fertility and pregnancy, is the company’s first consumer product.
