A randomized controlled trial published October 8, 2026, determined that transcutaneous electrical nerve stimulation (TENS) provided no pain reduction during IUD insertion compared to a sham treatment. The study, which evaluated 98 adult participants, indicates the intervention did not improve the patient experience for those undergoing the procedure.
Why it matters
Managing discomfort during IUD insertion is a common clinical priority, but this research suggests that high-frequency TENS may not be an effective tool for pain control. Patients should discuss alternative pain management options with their physician, as individual experiences vary significantly based on medical history.
In a randomized controlled trial of 98 adults with a median age of 29, researchers compared 80 Hz TENS against a sham device during IUD insertion. Results showed no significant difference in pain scores between the two groups.
The players
Mount Sinai Medical System
A comprehensive academic health system that serves as a clinical site for research on gynecological procedures.
Yale New Haven Health System
A major academic health network that facilitates research in women's health and reproductive care.
The details
The trial involved participants receiving either active high-frequency TENS at 80 Hz or a sham device, alongside standardized oral ibuprofen (600-800 mg) and transabdominal ultrasound guidance. While the TENS group reported a higher likelihood of recommending the intervention to a friend, this subjective assessment did not correlate with measurable pain reductions. Clinicians in the study consistently underestimated patient-reported pain scores, which averaged 60.5 mm compared to the 48.9 mm they estimated.

Health Landscape
This study adds to the growing body of literature evaluating pain management protocols for common gynecological procedures. It highlights the importance of clinical trial validation when adopting new supportive care measures in reproductive health.
If you are planning an IUD insertion, discuss effective pain management strategies and expectations with your healthcare provider. Be aware that nulliparous patients in this study reported higher pain levels, and communicating your personal comfort needs remains a vital part of the procedure.
The takeaway
While TENS therapy did not reduce pain in this study, the findings underscore the importance of realistic expectations for in-office procedures. Talk to your physician about the full range of available pain relief options to ensure your comfort during an upcoming appointment.
