In theory, used tampons could offer clues to health and disease

Almost like a 23andMe test, but for women, and with menstrual tissue instead of spit. One of the company’s co-founders, Ridhi Tariyal, calls what they’re testing “the menstrualome.” Akin to the microbiome or the genome, the menstrualome as they’ve defined it is the world of information contained within women’s menstrual cycles. Expelled menstrual tissue is “a highly underutilized, underexplored specimen that could really break open women’s reproductive health,” Tariyal told Forbes in 2017. “But to date everyone has thought it’s too gross to engage in.” Also: “Nothing would make us happier than displacing the PAP smear.” In theory, the mensturalome could reveal clues not just about endometriosis , but also, perhaps, about STIs, PCOS, certain cancers, and fertility status. According to the NextGen Jane website: “Every single month during your period, your body is providing you with a natural biopsy when it sheds your endometrial lining. What could we learn if we had the tools to listen?” The site also suggests that users may one day be able to “Trade in your GYN’s speculum and stirrups for organic cotton.” But can it work? It remains to be seen. So far, the NextGen Jane smart tampon has “shown promise in identifying endometriosis when compared to laparoscopy tests,” according to a recent Ozy story, and more trials are scheduled for later this year . Outside of their trials, a 2018 study found that menstrual fluid can be a “useful,” noninvasive diagnostic tool for identifying endometriosis in particular. “Diagnosing diseases from menstrual blood is difficult,” however, as Dayna Evans notes in the MIT Technology Review, and in light of the fall of Theranos, there is heightened skepticism over companies aiming to “reinvent the blood test.” NextGen Jane, which was founded in 2014, has already raised at least $2.3 million, and the founders are currently trying to raise more to patent a tampon-wringing device. After that, they’d raise more money to run a small trial that could establish whether or not menstrual blood can, in fact, be used for diagnostic purposes. Tariyal estimates, to Evans, that this would take about two years. Interested menstruators can sign up to be a menstrualome Beta Tester, which presumably entails using one of NextGen Jane’s prototype kits and then sending it back to them, although the testing hasn’t actually started yet. The only way this could be more interesting, in my opinion at least, is if they were doing this all with menstrual cups.
