Leave it to famed biohacker Bryan Johnson to have everyone wondering what’s going on down there.
The health nut sent social media into a frenzy last week after posting a late-night update about his girlfriend, Kate Tolo — and her top-tier vaginal test results.
“Just gave Kate oral sex. Goodnight, everyone,” Johnson, 48, wrote on X, before following up with a screenshot of her vaginal health report and a bold claim: she has the “top 1% of all vaginas.”
Johnson explained that her sample is dominated by the single most protective bacterial species a vagina can host — Lactobacillus crispatus. Research suggests only about 25%-30% of reproductive-age women globally are L. crispatus-dominant. ‘Dominant’ typically means over 50%, and Kate’s result was 98.7%. He also noted she tested negative for a range of sexually transmitted infections and diseases.
Of course, standard STD-testing and annual gynecological exams are routine, but comprehensive at-home vaginal tests, such as the one Tolo took, can also provide some deep insights into overall health.
Tolo seemed to have used the Vaginal Microbiome Test from Tiny Health, which retails on Amazon for $249 — currently on sale for $214. Less than 20 tests are left on Amazon, but more kits are available directly through the Tiny Health site, which also sells popular gut tests for adults, kids and babies.
Other health-tech companies like Evvy and Viome also offer vaginal microbiome tests starting at $169.
Tiny Health’s at-home vaginal health test includes a simple swab kit that’s mailed back for advanced sequencing. It measures biomarkers, detects bacteria linked to BV and yeast infections and tracks beneficial Lactobacillus alongside disruptive microbes tied to vaginal health and fertility.
According to the company, results take 3 to 4 weeks and include expert-backed guidance with tailored diet and lifestyle recommendations if imbalances are found. Reviewers say it’s simple to use, the results are straightforward and the insights are valuable even without active vaginal health concerns.
“Easy to use and gave me very good insights,” one reviewer shared on Amazon. “I’m a pretty healthy person, but I have some autoimmune issues. The results gave me two areas to improve and even showed how the results correlate to my health issues.”
Johnson also highlighted the importance of evaluating vaginal health in his X post — an area that many other health experts have also stressed is connected to overall health and wellbeing.
“A vaginal microbiome is downstream of everything: sleep, glucose control, stress, gut health, sexual health, immune function, what you eat and what you put in it,” the biohacker concluded.
