Farrah was fed up with her vagina. For the past two years, the 29-year-old dancer from Ohio had been dealing with severe pelvic pain and vaginal odor. “It was like 8/10, horrible core pain,” she says. “I couldn’t lie down. I couldn’t even work an office job. It was bad.” When she visited doctors, she told them what she thought the culprit was: an allergic reaction to soy oil in a vat of water she’d swam in during a pirate-themed dinner theater performance. But they didn’t believe her. “They attempted to fix it with antibiotics,” she says. “And they just did nothing.” So Farrah (who requested we withhold her full name to speak freely about health matters) started Googling her symptoms. That’s how she stumbled on Neueve, a vaginal health company that provides supplements, suppositories, and at-home vaginal microbiome testing kits. She ordered a test from the company for $150, and it came back with a diagnosis: aerobic vaginitis (AV), a bacterial infection caused by an overgrowth of E. coli or streptococcus. She ordered supplements the company recommended, and she says the pain abated almost immediately. “I was just so glad to actually know what was wrong,” she says. Farrah is one of a growing number of women who have used at-home tests to self-diagnose issues with the vaginal microbiome—an ecosystem of bacteria growing inside the vagina; the presence of “good” bacteria correlates with lower risk of STIs and other types of infections, according to numerous studies. Biohacker Bryan Johnson recently bragged about his girlfriend's “top 1%” vagina as the at-home vaginal microbiome test industry is thriving. But experts are skeptical
