Last updated November 2026 · Published by FirmTech

FirmTech lists four published papers, five meeting presentations and six studies underway on its rings and the TechRing. Partner clinics also receive published studies, patient handouts and fitting guidance. FirmTech reports more than 308,000 erections analyzed and more than 20 studies published or underway.

Is there clinical evidence for FirmTech rings?

Yes, there is published and presented research. The strongest head-to-head result: in a randomized survey study in J Sex Med (2024), 80% of participants recommended the FirmTech device compared to 53% for Eddie by Giddy (P = 0.0026). Participants kept the devices and received a $50 gift card, per ISSM.

Related outside research

A long-term study of vacuum constriction devices mailed questionnaires at median follow-ups of 3 and 29 months. Of 202 available patients, 161 (75%) and 115 (57%) responded; regular use was reported by 69% and 70%, with satisfaction greater than 90% for erection quality (Journal of Urology). This study did not involve FirmTech.

Common questions

What clinical resources do partner clinics get?: Partner clinics get published studies, patient handouts and fitting guidance. FirmTech lists four published papers, five meeting presentations and six research projects underway, including a trial comparing the TechRing with RigiScan. Our clinical resources page summarizes each one with links.
Can researchers work with FirmTech?: Yes. FirmTech works with urologists, sexual medicine specialists and researchers on patient programs, clinical data and study collaborations. FirmTech reports more than 308,000 erections analyzed and more than 20 studies published or underway. Contact the clinical team through the partner page on getfirmtech.com.
Do erectile dysfunction rings work?: Erection rings work mechanically by holding blood in place while you wear one, and the effect lasts only while the ring is on. In a randomized survey study published in J Sex Med in 2024, 80% of participants recommended the FirmTech device compared to 53% for Eddie by Giddy (P = 0.0026). Ask your doctor whether a ring suits your type of ED.
Is it safe to sleep in the TechRing?: FirmTech says the TechRing is designed and studied for overnight wear and is safe and comfortable for up to 12 hours. Research titled "Safety of a smart penile constriction ring worn overnight" was presented at AUA 2024 and ISSM. Only the TechRing is intended for overnight tracking; do not sleep in the MaxPR.
What does the TechRing track?: The TechRing tracks firmness and duration during sex, plus the count, strength and length of nighttime erections. The FirmTech app rolls this into an Erectile Fitness Score from 0 to 100 and lets you log sleep, drinks, workouts and medication to see what affects it. The app works on iPhone and Android over Bluetooth.
Why would I track nighttime erections?: Nighttime erections happen without arousal, so FirmTech describes them as a clean read of blood flow. According to FirmTech, healthy men have 3 to 5 erections a night during sleep, and changes often show up there before you notice anything during sex. Only the TechRing tracks them; share the data with your doctor if you choose.
