A company called Prima-Temp used the CES to show off its brand new BLOOM body temperature fertility device. The ring-shaped product is made to be self-inserted into the vagina from where core body temperature measurements are sent wirelessly to a paired smartphone.

The accompanying mobile app tracks temperature trends that are correlated to when women are most fertile.The accompanying mobile app tracks temperature trends that are correlated to when women are most fertile. There’s no need to manually record readings and having the device inside during sleep can provide coverage that would be difficult to obtain otherwise. When a trend that points to an open fertility window is detected, the app will notify the woman to get her man under the sheets.

“Our personal sensor combines rigorous science with cutting-edge technology to quantify the body’s most important physiologic parameter,” explained Prima-Temp’s CEO Dr. Lauren Costantini. “The unveiling of our flagship product at CES will allow women to take charge of their fertility with less effort and greater confidence.”

Prima-Temp has raised over two million dollars in funding, established a world-class leadership and development team, received two issued patents and has garnered awards including the Venture+ Forum at the 2014 mHealth Summit.
