Revealing His Girlfriend’s Private Life for a $2.6 Million Experiment: “Storing Menstrual Blood at Minus 80 Degrees”

US Billionaire Launches Women's Reproductive Health Project
Collects 14 Million Data Points Related to Menstrual Cycles
"According to Him, His Girlfriend's Vaginal Health Is in the Top 1%"

Brian Johnson, the American billionaire who previously made headlines for transfusing his own son's blood in a bid to reverse aging, has once again attracted attention—this time by revealing that he is storing his girlfriend’s menstrual blood in a freezer as part of a women’s reproductive health project.

According to the New York Post on August 6 (local time), Johnson recently shared on his X (formerly Twitter) account that he has “about 10 ml of Kate’s menstrual blood stored in a freezer at minus 80 degrees Celsius.”

The menstrual blood storage is part of a women’s reproductive health project led by Johnson’s girlfriend, Kate Tollo. Tollo is conducting an experiment that involves collecting 14 million data points related to her menstrual cycle over the course of 100 days. A total of 2.6 million dollars (about 3.7 billion won) is being invested in the project, which was created to fill the research gap in the relatively underexplored field of women’s reproductive health data. Significantly, Tollo’s own diagnoses of endometriosis and polycystic ovary syndrome served as the critical motivation for launching the initiative.

Johnson explained that the frozen menstrual blood was collected from Tollo during her last period. He noted, “This sample is extremely valuable but has not been properly utilized until now. It can be used to directly measure the intrauterine environment without a surgical biopsy.”

Johnson plans to use this blood sample to investigate not only uterine lesions, but also traces of microplastics, endocrine disruptors, and so-called ‘forever chemicals’ known as perfluoroalkyl substances (PFAS).

Highlighting the importance of the project, Johnson stated, “More than one in ten women experience endometriosis, yet it takes 7 to 10 years on average to receive a diagnosis.”

Johnson has been unhesitant about publicly sharing even highly personal health data about his partner. In May, referencing Tollo’s test results, he claimed, “Her vaginal health is in the top 1% among all women, with 'Lactobacillus crispatus,' a beneficial bacteria, predominating in her body.”

He added, “Globally, only about 25% to 30% of women of reproductive age have this bacteria as the dominant strain, and typically, ‘dominant’ means over 50%, but in her case, it’s 98.7%.”

Johnson, who previously described himself as a “difficult partner to date” due to his strict health management, has now been dating Tollo for three years. The couple made their relationship public last December. In his post, Johnson expressed gratitude, saying, “Thank you to my partner for becoming the subject of my scientific experiment,” while Tollo responded to his post with a comment, “Thank you for taking care of me,” openly displaying their affection for each other.
