Bryan Johnson, a well-known biohacker, recently shared detailed information about the vaginal health of his girlfriend, Kate Tolo, on social media. Johnson highlighted that Tolo's vaginal microbiome is exceptionally healthy, with a 98.7% dominance of Lactobacillus crispatus, a bacteria associated with lower risks of bacterial vaginosis, urinary tract infections, yeast infections, HPV persistence, HSV-2, and HIV acquisition. He emphasized that the microbiome reflects overall health factors such as sleep, stress, gut health, and diet. Tolo also commented on the post, noting that oral sex carries genuine health risks, including the transmission of HSV-1, HPV, and antibiotic-resistant gonorrhea, and can impact the vaginal microbiome. Despite the unusual nature of the posts, Tolo expressed gratitude for Johnson's focus on their collective health. The couple's relationship began professionally at Johnson’s company, Kernel, and later developed romantically. The post sparked reactions online,
