In recent years, women have increasingly turned to personal technology to provide insight into their own fertility. The women’s health market is awash with wristbands, sleep tracking devices, and sensor-laden wearables that can track the myriad factors that indicate imminent ovulation. These technological solutions can not only help women trying to get pregnant, but also those who may want to get pregnant later in life and want to measure their ovarian reserve. Of course, there’s still a great deal of guesswork involved in all of these tests, devices, and apps. But that hasn’t stopped entrepreneurs from diving into fertility tech with gusto. Arielle Pardes charts Silicon Valley’s infatuation with fertility, including a startup that now offers an at-home testing kit that makes checking one’s reproductive health as simple as submitting a 23andMe gene sample.

Some notes: Read Arielle’s story on Silicon Valley’s dive into fertility tech. Here’s the test kit from Modern Fertility. Lauren is out this week, but will be back next week to talk about Apple.
