A British company has developed a new fertility monitor that helps people calculate the exact days of the month when a woman is most likely to conceive.
The slim, walnut-sized device, which is worn like a patch underneath the armpit, takes body temperature measurements up to 20,000 times a day.
Dr. Jacques Moritz, director of gynecology at St. Luke's-Roosevelt Hospital, said that DuoFertility is a very fancy thermometer that has human feedback linked to it, the New York Daily News reported.
After wearing it for 3-4 days, the temperature data can be uploaded to a computer, along with other observations regarding menstrual cycle, sleep habits and moods, and then it can be sent to a lab at Cambridge University in England.
Within days, the lab email assessments of a woman's fertility patterns - including the exact days the couple should try to conceive.
Cambridge Temperature Concepts is the company behind DuoFertility.
