When you’re considering getting an IUD, one of the most important tools your healthcare provider will use is called a tenaculum. I want to explain what this tool is in simple terms, because many women aren’t familiar with it until they’re already in the doctor’s office. A tenaculum looks like a long pair of scissors with curved hooks at the end and doctors have been using it for many years during IUD insertions. They use this tool to hold your cervix steady while they put in the IUD.
Think of it like this – your cervix is the doorway to your uterus and the doctor needs to keep that doorway still and in the right position to safely place the IUD. The tenaculum helps them do this by gently gripping the cervix. However, many women find this part of the procedure uncomfortable or painful, which is something we need to talk about openly. When the tenaculum grips your cervix, it can cause cramping and sometimes a small amount of bleeding.
This is because the cervix has many nerve endings and when the tenaculum’s hooks grab onto it, you might feel a sharp pinch or cramping sensation. Your doctor might tell you it will feel like “a little pinch,” but for many women, especially those who haven’t had children, it can be more intense than that.
The Evolution of IUD Insertion Tools
As medical technology advances, healthcare providers and researchers have been working hard to find better ways to make IUD insertion more comfortable for patients. The traditional tenaculum, while effective, has remained largely unchanged for decades, which has led many medical experts to question whether we can do better.
A new company called Aspivix has recently developed an innovative alternative that’s getting a lot of attention in the medical community. Their device, called Carevix, uses suction instead of metal hooks to hold your cervix in place. This is a big deal because it means we might be able to avoid the puncturing and pinching that comes with the traditional tenaculum. When I looked at the research, I found that many women who tried this new method reported less pain during their IUD insertion.
The doctors who tested it said they could still position the cervix just as effectively, but without causing as much discomfort to their patients. This is especially important because fear of pain during insertion is one of the main reasons why some women choose not to get an IUD, even though it’s one of the most effective forms of birth control available. When we talk about improving medical procedures, it’s not just about making them work better – it’s about making them more accessible and less intimidating for everyone who might benefit from them.
What Studies Tell Us About the Tenaculum
When we look at the scientific evidence about the tenaculum and IUD insertion pain, researchers have gathered some important information that helps us understand why changes are needed. In a recent study that involved nearly 300 medical procedures across different healthcare centers in both Europe and the United States, doctors found some interesting patterns.
The traditional tenaculum method often caused significant discomfort, particularly for women who had never given birth before. In fact, one study showed that about 80% of these women reported experiencing severe pain during their IUD insertion when using a traditional tenaculum. This is because their cervix had never been through the dilation process that happens during childbirth, making it more sensitive to the tenaculum’s grasp.
The medical community has been tracking these experiences carefully and they’ve found that the pain isn’t just from the initial grip of the tenaculum – it can also trigger uterine contractions, which adds another layer of discomfort to the procedure. When doctors measured pain levels in their patients, they consistently found that the moment when the tenaculum grips the cervix is often described as one of the most uncomfortable parts of the entire IUD insertion process.
Pain Management During IUD Insertion
Let’s talk about how the new suction-based devices compare to the traditional tenaculum in real-world settings. In a carefully designed study where doctors randomly assigned 100 women to either the new suction device or the traditional tenaculum, they found some promising results. The women who had their procedure done with the suction device reported noticeably less pain overall. This was especially true for those who had never given birth – the group that typically experiences the most discomfort during IUD insertion. The doctors conducting these procedures also reported positive experiences with the new tool.
About 76% of healthcare providers successfully used the suction device on their first try and this success rate jumped up to 89% after they had performed about 10 procedures. This shows that while there might be a small learning curve for doctors switching to the new method, they can quickly become proficient with it. The research also revealed that the suction method reduced the risk of cervical bleeding and tissue damage compared to the traditional tenaculum, which typically leaves small puncture marks where it’s hooks grip the cervix.
Current Limitations and Future Improvements
While the new suction devices show promise, it’s important to understand their current limitations and what they can and cannot address.

Future Directions and Ongoing Research
The medical community continues to investigate ways to improve IUD insertion procedures, with several promising developments on the horizon. Current research focuses not only on perfecting suction-based devices but also on developing entirely new approaches to cervical stabilization during IUD insertion. Scientists are exploring various materials and mechanisms that could provide adequate stability while minimizing tissue trauma and patient discomfort. Additionally, researchers are investigating the role of different pain management protocols, timing of insertions during the menstrual cycle and the potential benefits of ultrasound guidance during placement.
The growing attention to patient comfort during gynecological procedures represents a significant shift in medical practice, moving away from the historical tendency to minimize or dismiss women’s pain during these procedures. This evolution in medical practice reflects a broader understanding that improving patient comfort isn’t just about reducing pain – it’s about increasing access to effective contraception options and improving overall healthcare outcomes for women.
Conclusion
The evolution of IUD insertion techniques, particularly the transition from traditional tenaculum to modern suction-based devices, represents a significant milestone in women’s healthcare. As we’ve examined throughout this discussion, the medical community’s growing focus on patient comfort and procedure optimization has led to meaningful improvements in how we approach IUD insertions. The development of alternatives to the conventional tenaculum demonstrates the healthcare industry’s commitment to addressing long-standing challenges in reproductive healthcare delivery.
The research evidence clearly indicates that newer technologies like the Carevix system offer promising alternatives to traditional methods, particularly for patients who have never given birth. While these innovations don’t completely eliminate all sources of discomfort during IUD insertion, they represent an important step toward making long-acting reversible contraception more accessible and less intimidating for a broader range of patients.
