Billionaire Bryan Johnson Stores Girlfriend's Menstrual Blood for Uterine Analysis

American biohacker and billionaire Bryan Johnson is employing an unconventional method in his pursuit of longevity and health: storing his girlfriend's menstrual blood for analysis.

Johnson, 48, who dedicates significant resources to anti-aging research, revealed on social media platform X that approximately 10ml of his girlfriend Kate Toloo's menstrual blood is being kept in a freezer at -80 degrees Celsius. He described the samples as "precious" but acknowledged they are "not being utilized properly" yet.

According to Johnson, this method provides a way to "non-invasively look inside the uterus." He explained that the blood was collected during Toloo's last menstrual cycle. Johnson intends to use the samples to search for signs of lesions, microplastics, endocrine-disrupting chemicals, and PFAS (per- and polyfluoroalkyl substances), often referred to as "forever chemicals," which can accumulate in the body over time.

He asserted that this approach allows for data acquisition without the need for surgical biopsies and can be repeated each cycle. Johnson believes it is more effective than indirectly estimating uterine conditions through standard blood tests, as it offers a direct measurement of the uterine environment. Toloo, who has been diagnosed with endometriosis, is reportedly undergoing a 100-day project that involves collecting 14 million biometric data points related to her menstrual cycle.

This unusual practice highlights Johnson's extreme dedication to his anti-aging mission, seeking novel ways to gather health data, even if it involves controversial methods. The goal is to gain deeper insights into female reproductive health and potentially identify health issues early.
