A role for TENS in IUD insertion?
We recently posted on instagram about the role for TENS devices, particularly portable ones, in procedures that can cause discomfort such as IUD insertion. You guys loved it! We thought we would delve a little deeper here...
Many people are told that IUD insertion is quick and straightforward — but for some, it can be painful and distressing. Pain experiences during IUD insertion vary widely, and it’s reasonable to want support options ahead of time.
While medication-based pain relief is sometimes offered, non-pharmacological tools like TENS are increasingly being discussed as part of a broader comfort plan. This article explores how TENS may help during IUD insertion, what the evidence and clinical experience suggest, and practical considerations if you’re thinking about using it.
Why can IUD insertion be painful?
During IUD insertion, the cervix is gently opened and the uterus is stimulated, which can trigger cramping and discomfort. For some people, this sensation is brief and manageable; for others, it can be more intense.
Factors such as cervical sensitivity, anxiety, previous pelvic pain, endometriosis, or a heightened nervous system response can all influence how pain is experienced. This variability is why a one-size-fits-all approach to pain relief often falls short.
What pain relief options are commonly used?
Pain management during IUD insertion can include a range of approaches, depending on the provider and individual needs. Common options may include:
• Over-the-counter pain relief such as NSAIDs
• Local anaesthetic or cervical block (where available)
• Breathing techniques and supportive positioning
• Distraction and grounding strategies
• Transcutaneous Electrical Nerve Stimulation (TENS)
These approaches are often most effective when used in combination rather than in isolation.
How TENS may help during IUD insertion
TENS works by delivering gentle electrical impulses through the skin, which can help modify how pain signals are processed by the nervous system. One commonly referenced mechanism is the “gate control theory” of pain, where non-painful sensory input can reduce the perception of pain.
During procedures such as IUD insertion, TENS may help by reducing the intensity of cramping sensations, supporting muscle relaxation, and providing a sense of control at a time that can otherwise feel overwhelming.
It’s important to note that TENS does not eliminate all sensation. Instead, it may change how pain is perceived and improve a person’s ability to cope with the procedure.

What does the evidence and clinical experience suggest?
Research into pain management for IUD insertion is ongoing, and experiences with TENS can vary. Emerging evidence and clinical use suggest that TENS may be a helpful form of insertion pain relief for some people, particularly when used alongside other comfort measures.
In pelvic health settings, TENS is commonly used to support people experiencing menstrual, pelvic, and procedural pain. Many clinicians report that it can help reduce distress and improve tolerance, even if it does not remove pain entirely.

Final thoughts...
Everyone deserves to feel supported during medical procedures. While pain experiences vary, having a plan — and tools that support both body and nervous system — can make a meaningful difference.
If you already use TENS for pelvic or period pain, it may be worth discussing whether it could be a supportive option during IUD insertion as part of a broader pain management approach.
