Bryan Johnsons girlfriend is tracking her own nighttime erections with a special techno tampon

A device that measures nighttime female “erections” to gauge longevity? Now that’s a biohacker’s wet dream.Every night, Kate Tolo inserts a $15,700 “research grade erection device” into what her boyfriend and business partner, biohacker Bryan Johnson, famously called her “top 1%” vagina.In fact, both of them wear an erection tracker nightly.Johnson says he’s looking to maintain healthy erections, which some experts agree is a predictor of longevity for men.And Tolo — despite not having a penis — wants in on the action.Tolo says women get “erections” too — and it’s possible that tracking them could give ladies similar longevity insights.She claims to be picking up on research from more than 40 years ago that could pull back the curtain on women’s sexual dysfunction and possibly even show early signs of heart issues, as it does in men.Yes, women really do have “erections,” research shows.

During sleep, blood flows to the clitoris, causing it to swell as if aroused.The clitoris is actually very similar to the penis: They are the same organ for the first 2 months of development in the womb.And using devices similar to Tolo’s — a tampon-shaped light sensor, which she calls her “techno tampon” — research has shown that blood flow in the vaginal tissues does spontaneously surge during sleep, which is also associated with arousal.“The light sensor inside my probe is the same kind smartwatches use to read your heart rate,” she explained.That said, it’s been a long time since someone has published research on insights this tech can give us on female health — or improved upon the tech at all, she says.

“The tech was invented in 1975 and hasn’t changed in 50 years.”Tolo’s vaginal “erection” data is not easy to get.Her device costs $15,723.68 and is like “lab equipment in my bedroom,” she said.“I insert the 5cm probe [and] tape a wire to my leg that is plugged into a machine and a laptop.

The laptop can...
