Bryan Johnson, a biohacker known for his efforts to reverse biological aging, has sparked controversy by sharing intimate details about his partner’s vaginal health. On social media, he revealed that Kate Tolo’s vaginal microbiome score is 100/100, placing her in the top 1% of all vaginas.
Johnson, 48, and Tolo, 30, have been dating for over three years. Tolo is also a co-founder of the longevity startup Blueprint alongside Johnson. He disclosed that her microbiome is dominated by Lactobacillus crispatus at an impressive 98.7%.
This particular strain is significant; only about 25-30% of reproductive-age women globally have a L. crispatus-dominant microbiome. The lab analysis reported no negative findings in Tolo’s microbiome sample, such as sexually transmitted infections (STIs).
Johnson’s post included a provocative comment: “Just gave Kate oral sex. Goodnight everyone.” This statement led to discussions about sexual health risks and the importance of communication regarding intimate practices.
Tolo responded by emphasizing that oral sex carries genuine health risks, stating, “Oral sex isn’t talked about enough despite carrying genuine risks.” She highlighted that maintaining a healthy vaginal microbiome can lower the risk of conditions like bacterial vaginosis (BV), urinary tract infections (UTIs), and even HPV persistence.
Johnson argued that understanding sexual health is crucial for longevity and overall well-being. He noted that a healthy vaginal microbiome contributes to improved outcomes in various reproductive health areas.
This revelation raises important questions about privacy in personal relationships and the boundaries of public discourse on intimate topics. As of midday, reactions from the public vary widely, with some praising the openness while others criticize it as inappropriate.
No timeline has been shared regarding any potential follow-up discussions or further disclosures from Johnson or Tolo.
