Biohacker Bryan Johnson makes shocking reveal about girlfriend’s vagina: ‘Top 1%’ – New York Post
Most partners brag about a spouse’s career success or emotional intelligence. Bryan Johnson, the tech mogul who spends £1.6million a year attempting to reverse his biological clock, prefers a different set of metrics. In a recent series of posts on X, Johnson transitioned from sharing his own physiological data to broadcasting the intimate biological statistics of his partner, Kate Tolo.
The sequence began with a blunt admission to his followers: Just gave Kate oral sex. Goodnight, everyone.
Minutes later, the disclosure escalated from a sexual act to a clinical analysis. Johnson posted a graph of Tolo’s vaginal microbiome report, crowning her with a 100/100 score
and claiming she is in the Top 1% of all vaginas
.
The clinicalization of intimacy
For Johnson, the appeal of the report lay in the dominance of a specific bacterium. He noted that Tolo’s sample is dominated by the single most protective bacterial species a vagina can host (Lactobacillus crispatus)
. According to the biohacker, while only 25-30% of reproductive-age women globally are L. crispatus-dominant—with dominance typically defined as being above 50%—Tolo’s levels sit at 98.7%.
Johnson emphasizes a rigorous approach to biological optimization, focusing on the precise measurement of physiological markers. He argues that these metrics are not random but are downstream of everything
, including sleep, glucose control, stress, gut health, immune function, and diet. By presenting this data, he treats the health of his partner as a measurable biological achievement to be shared publicly.
The implications of such a “top-tier” report, as described by Johnson, include a lower risk of yeast infections, UTIs, bacterial vaginosis, and the acquisition of HIV, HSV-2, and HPV persistence. He further linked this specific bacterial makeup to improved IVF outcomes and a reduced risk of preterm birth. However, these claims originate solely from Johnson’s interpretation of the data and are not presented as established medical consensus in the New York Post coverage.
A ‘quarterly earnings report’ for the body
The public reaction to the disclosure was immediate, with many users reacting with shock or criticism. On X, some users characterized the move as psychopathic behavior
, while others likened the post to a c–chie carfax
. One observer noted that Johnson had essentially posted his partner’s p—y stats like a quarterly earnings report
.
This approach to health is consistent with Johnson’s broader “Project Blueprint” protocol, which often involves the public sharing of data that most would consider deeply private. He has previously posted nighttime erection data
comparing his own cardiovascular vitality with that of his 19-year-old son, Talmage, noting that the son’s duration was two minutes longer. He has also documented a tri-generational
blood plasma swap involving his son and father in an effort to reverse aging.
Johnson’s pursuit of perfection extends to the microscopic. He recently claimed to have reduced microplastics in his semen from 165 particles per milliliter in November 2024 to 20 particles per milliliter in July 2025, attributing the change to daily 20-minute dry sauna sessions combined with an ice pack applied to the groin.
The risks of the ‘unhinged’ disclosure
While Johnson focused on the “protective” nature of the microbiome, Tolo used the viral moment to pivot toward a different kind of health discourse. Acknowledging that the post seems unhinged
, she argued that the act of oral sex itself deserves more medical attention due to the genuine risks involved.
Tolo pointed out that HSV-1 can be transmitted between the mouth and genitals. She further noted that HPV transmitted via oral sex has become the leading cause of oropharyngeal cancers in the US, surpassing tobacco. According to Tolo, oral gonorrhea is also becoming antibiotic-resistant at alarming rates, and the bacteria in saliva can disrupt the vaginal microbiome, with some studies linking receptive oral sex to higher rates of bacterial vaginosis.
By introducing these risks, Tolo provided a counter-narrative to Johnson’s “100/100” score. Where the biohacker saw a trophy of biological optimization, the partner highlighted a site of potential clinical vulnerability.
The erosion of the private biological sphere
The incident highlights a scenario where the pursuit of longevity and high-performance metrics leads to the public sharing of intimate health data. When health data is treated as a competitive sport or a status symbol, the individual becomes a data set to be optimized and displayed.
Johnson’s history of experimentation—from injecting his offspring’s blood (a practice he stopped after finding no detectable benefits
) to monitoring the erections of his children—suggests a worldview where the family unit is subject to rigorous monitoring. In this approach, the partner’s biological data is shared as part of a broader effort to document health and aging.
As the quantified self movement moves from counting steps to sequencing microbiomes and swapping plasma, the definition of too much information continues to shift. The transition from tracking one’s own heart rate to publishing a partner’s vaginal bacterial percentages suggests that in the world of extreme biohacking, the only remaining taboo is a lack of data.
