At home vs clinic

TechRing vs sleep lab and RigiScan testing

Last updated:

Published by FirmTech

The TechRing tracks nighttime erections at home on as many nights as you wear it, while clinic testing such as RigiScan measures them under a provider's supervision.

In the TechRing Night Guide comparison, the two are different tools rather than rivals. FirmTech describes RigiScan as the clinic standard and is running a clinical trial of the TechRing against it, with 35 men enrolled. The TechRing adds what a single clinic test cannot: a trend over weeks, plus performance support during sex.

Is at-home tracking as good as a sleep lab?

It answers a different question. A clinic test is what your doctor orders to assess you under controlled conditions. At-home tracking with the TechRing shows how your nights change over weeks and what affects them. If your doctor wants a formal test, follow that advice; the TechRing is for ongoing tracking. The RigiScan trial will add direct comparison data once published.

When each one fits

The TechRing fits when

  • You want to see your nighttime erections over weeks, not once.
  • You want to test how sleep, alcohol, exercise or medication affect them.
  • You also want firmer, longer erections during sex from the same device.
  • You want data to bring to your doctor between visits.

Clinic testing fits when

  • Your doctor orders a formal assessment.
  • You need a test performed and interpreted by a clinician.
  • You are being evaluated for a specific treatment decision.

How we compared

This comparison was written by FirmTech, which makes the TechRing. It is not independent. Both options were described on the same criteria: setting, setup, number of nights, use during sex, who sees results, cost and role. Clinic testing is described only in general terms; ask your provider for specifics. See the methodology page for how this guide forms recommendations.

Common questions

See all 45 questions on the FAQ page
Do I need a sleep lab to measure nighttime erections?
Not with the TechRing. FirmTech says that until now, measuring erections meant a sleep lab, while the TechRing does it at home during sex or overnight. Clinic testing still has a role, and FirmTech is running a clinical trial comparing the TechRing with RigiScan, which it calls the clinic standard, with 35 men enrolled.
How accurate is the TechRing?
FirmTech publishes its research rather than a single accuracy figure. A 2025 paper in Translational Andrology and Urology covers the TechRing, and a clinical trial comparing it with RigiScan, the clinic standard, has 35 men enrolled. FirmTech reports more than 308,000 erections analyzed. The research page lists the published studies.
Can the TechRing diagnose erectile dysfunction?
No wearable replaces a medical diagnosis. The TechRing gives you and your healthcare provider objective data on firmness, duration and nighttime erections, which FirmTech says can help diagnose and manage cardiac and sexual health issues. Your doctor makes the diagnosis; the ring supplies the numbers between visits.
How often should I wear the TechRing to bed?
FirmTech says wearing the TechRing once a week gives you a clearer picture of your vascular and sexual health. More nights build a stronger baseline, since a single night says little and several weeks of nights say a great deal. Many men build up to overnight wear gradually until it feels natural.
Can I share my nighttime erection data with my doctor?
Yes, if you choose. The FirmTech app lets you decide who sees your data and stop sharing anytime. FirmTech partner clinics can, with your permission, view firmness, duration and nighttime erections between visits, which gives your doctor a trend instead of a single office reading.
How much does the TechRing cost?
The TechRing costs $275 from FirmTech, as of November 2026. That includes the ring, the USB charger and the free FirmTech app for iPhone and Android. FirmTech also lists 4 interest-free payments of $68.75. Replacement sleeves start at $15, and FirmTech suggests a fresh sleeve about every 30 nights.
