The best part of the new algorithm is that it comes in a home test version, so you don’t even have to go to a doctor to gain more information about your fertility and your options. The test is called PreIVF, and it costs $250–a small price compared to the thousands of dollars a failed in-vitro procedure can cost. It takes into account things like body type, history of smoking, blood and semen samples, and previous experiences with pregnancy to offer a more accurate test than a simple number. Univfy uses aggregated data from thousands of couples and passes these through a machine-learning algorithm to continually improve their accuracy. Since over 150,000 in-vitro cycles are performed each year, this is a huge breakthrough for a lot of people going through a difficult process.
