Biohacker Bryan Johnson has claimed that he has managed to de-age his penis by 15 years thanks to his controversial rejuvenation methods.
In an interview with this website, the longevity entrepreneur — who is 47 but has the body of a man in his 30s — revealed that measuring night-time erections is one of the most important markers of health.
For men who have few erections a night may be suffering from a cardiovascular health problem, or another condition such as diabetes, he said.
Mr Johnson, who is 47 but has the penile health of a 22 year old, admitted he uses a specialist tracker that measures penis size throughout the night, to monitor his erections.
The device, which then gives him an ‘AndroAge score’ — the health and age of erections — marks one of the seven steps he takes to keep his penis health in check.
He told MailOnline: ‘When I first started measuring [nighttime erections], I didn’t know if it was a good idea. Is it lowbrow? Is it like a little off?
‘It turns out that — this is true for both men and women — that a man’s nighttime erections and a woman’s nighttime erections – the clitoris engorging — is one of the most important biomarkers of anything about our entire body.
‘So while it kicks up some giggles, it really is one of the most important things for all of us to know about our bodies and it’s just not talked about.’
Bryan Johnson has compared his nighttime erections with those of his son (pictured here) to measure his AndroAge – erection health age
In the morning, the Adam Sensor provides details of nighttime erections, including frequency and duration. Pictured above is the data of Mr Johnson (left) and his 18-year-old son (right)
He added: ‘No one spoke about this until I started talking about it. So it’s good for the headlines, but it’s also really good practically for people’s lives.
‘For example, men who do not have nighttime erections are at risk of 70 percent greater likelihood of premature death. So it’s a really significant health marker.’
His device, the Adam Sensor erection tracker, is a compact gadget that fits like a ring around the base of the penis, before men go to sleep.
The Adam Sensor — which launched in 2022 — tracks how often the penis engorges with blood, and for how long.
It then wirelessly communicates this information to the Adam Sensor 비닉스부작용 app on the man’s phone.
Upon waking up the man then turns off the measurement and then removes the sensor, at which point the app creates a report about the night’s erection activity, giving an AndroAge.
The device is available online for about $190 (£149.00). Due to high demand, 비닉스부작용 the company says there is currently a waiting list.
Last month, Mr Johnson tweeted the data from one night’s sleep comparing it with his son, Talmage’s, nighttime erections.

While Talmage had two more minutes of erections, their AndroAge’s were both reported to be 22 years old.
Despite being criticized for publishing such intimate information about his son, Talmage retweeted his father’s post, saying: ‘I’m grateful for the way my dad has raised me.’
In a blogpost on his website last year, Mr Johnson also revealed he had a seven step process to measuring his penis health and ‘de-aging his penis’.
Alongside nighttime erection tracking, he also undertakes semen analysis — regularly testing changes in sperm count, motility and morphology — and penis blood flow testing.
Urine flow tests, questionnaires scoring sexual function, prostate checks to measure size, and ‘core health practices’ such as a balanced diet and regular exercise, account for the other four.
But his comments also echo findings on erectile health that show men with erectile dysfunction are more likely to suffer other medical issues.
One study by US scientists, published in The Journal of Sexual Medicine, found men with erectile dysfunction had a 70 percent increased risk of an early death from any cause.
Another Dutch study found men with erectile dysfunction were up to 2.5 times more likely to develop cardiovascular disease, the leading cause of death globally.
Drugs like Viagra are used to manage erectile dysfunction in at least two thirds of cases, according to the NHS
A total of 4.57million prescriptions for sildenafil, more commonly known by the brand name Viagra, and other types of impotency drugs sold under the brand names Cialis and Levitra, were dished out by the health service in 2023
Men generally experience three to five erections per night, lasting about 45 minutes in total.
These erections help keep the penis healthy by occasionally flushing the organ with blood during the night.
