What does the research on the TechRing show?
Published and presented work on the FirmTech TechRing covers at-home erection measurement, overnight safety, and how constriction rings compare with PDE5 inhibitors. In recordings under 1 hour, median erection duration was 12.1 minutes at a firmness of 8.6/10; over 1 hour it was 30.5 minutes at 7.25/10. A trial against RigiScan is underway.

FAQ
Common questions
What research has been published on the TechRing?
Published papers include "Wearable penile devices: the TechRing" in Translational Andrology and Urology (2025) and a 2024 Journal of Sexual Medicine randomized survey comparing two medical-grade penile constriction devices. FirmTech has also presented at AUA, ISSM, SMSNA and the Japanese Society for Sexual Medicine, and lists more than 20 studies published or underway.
See this answer in the FAQHow many erections has FirmTech analyzed?
FirmTech reports more than 308,000 erections analyzed as of November 2026, which it describes as the largest erection database on earth, and more than 40,000 rings sold. These are FirmTech’s own figures, published on its clinical studies page, not the result of an independent audit.
See this answer in the FAQWhat did TechRing data show about erection duration and firmness?
In FirmTech’s published research summary, recordings under 1 hour had a median erection duration of 12.1 minutes with a firmness rating of 8.6/10. For recordings exceeding 1 hour, the median duration was 30.5 minutes with a firmness rating of 7.25/10. In that group, diabetes prevalence was 10.7% and 11.4% of participants were current smokers.
See this answer in the FAQHow common is erectile dysfunction?
Urology News reports that 50% of men experience ED by age 50. FirmTech’s research summary also notes that the incidence of ED increases with age, about 10% per decade. Numbers like these explain why clinicians look for simple ways to measure erectile function over time rather than at a single visit.
See this answer in the FAQIs erectile function linked to heart health?
Researchers have studied the link. A 2026 paper in Urology examined erectile dysfunction and coronary calcium scoring, and a 2024 paper in Urologiia examined overnight erections as a predictor of coronary heart disease. FirmTech also has a multi-center study underway on nighttime and during-sex rigidity versus coronary atherosclerosis in men over 40.
See this answer in the FAQHow does the TechRing compare to RigiScan?
FirmTech has a clinical trial underway comparing the TechRing with RigiScan, which it calls the clinic standard, with 35 men enrolled as of November 2026. Results were not yet listed as published on the FirmTech clinical studies page at that date. The practical difference today is setting: the TechRing records at home, during sex or overnight.
