You finally decide to get an IUD because you want reliable contraception without having to think about it every day.
Everything seems fine at first.
Then, during sex, you notice something you did not expect: a deep ache, cramping or discomfort that was not there before.
It can be confusing, especially if you have heard that an IUD should not interfere with your sex life.
So, can an IUD cause pain during sex?
An intrauterine device (IUD) can be associated with pelvic or sexual pain in some situations, but an IUD does not routinely cause painful sex. The position of the IUD, pelvic infections, underlying conditions and pelvic-floor muscle tension can all contribute to pain during intercourse.
If pain is persistent, severe, worsening or accompanied by bleeding, fever, unusual discharge or other concerning symptoms, medical evaluation is important. When pelvic-floor muscle tension contributes to the problem, pelvic-health physiotherapy may help.
Sometimes, an IUD may be associated with pelvic or sexual pain, but it is not accurate to assume that the device is always responsible.
The position of the IUD, the timing of your symptoms, vaginal or pelvic health, infections and pelvic-floor muscle tension can all influence what you feel.
And this is where the physiotherapy side of the story becomes important.
Pain during sex can cause the pelvic-floor muscles to tighten protectively.
If that tension continues, the muscles themselves can become part of the pain cycle.
Understanding where the pain comes from is therefore much more useful than simply asking whether the IUD is “causing” it.
- An IUD does not automatically cause painful sex.
- Deep pelvic pain and pain at the vaginal entrance can have different causes.
- IUD position, infection and other pelvic conditions may need medical evaluation.
- Pelvic-floor muscle tension can contribute to painful penetration.
- Not every pelvic-floor problem requires Kegel exercises.
- Pelvic-health physiotherapy can address muscular and movement-related contributors to pain.
- Persistent or severe pain should not simply be tolerated or treated as a normal effect of having an IUD.
What Is Pain During Sex?
Pain during or after sexual intercourse is commonly called dyspareunia.
It can feel very different from one person to another.
Some women describe burning or stinging around the vaginal opening.
Others experience pressure or a deep ache inside the pelvis.
Some notice pain only with deeper penetration or particular sexual positions.
You might also feel cramping for several minutes or hours afterward.
These differences matter because the location and timing of the pain can provide clues about what needs to be investigated.
Pain at the vaginal entrance, for example, may have a different cause from deep pelvic pain.
Can an IUD Cause Pain During Sex?
An IUD can be associated with pelvic discomfort in some circumstances, but having an IUD does not mean that painful sex is inevitable.
A systematic review examining hormonal and non-hormonal IUDs and female sexual function included 37 studies.
Overall, the researchers found mostly neutral effects across sexual-function domains.
Some evidence even suggested an improvement in sexual pain among women using levonorgestrel-releasing IUDs.
The evidence therefore does not support the idea that IUDs routinely cause sexual dysfunction or painful sex. (Ogle & Handy, 2024).
If pain develops while you have an IUD, the better question is:
What changed, when did it change and where exactly does it hurt?
Those details can help separate an IUD-related problem from other causes of dyspareunia.
Can an IUD Cause Deep Pain During Sex?
Deep pain during penetration deserves particular attention.
You may notice it only when penetration is deeper, with certain positions or when your partner moves at a particular angle.
An IUD sits inside the uterus rather than inside the vaginal canal.
Therefore, simply having an IUD does not mean that penetration is directly hitting the device.
However, deep pelvic pain can have several causes, including an IUD-related problem, pelvic infection, endometriosis, ovarian conditions or other pelvic disorders.
The sensation alone cannot tell you which one is responsible.
If deep pain is new, persistent or becoming worse, it is worth discussing with a healthcare professional rather than repeatedly pushing through it during sex.
Why Does Sex Hurt After IUD Insertion?
Timing can provide an important clue.
Some cramping and pelvic discomfort are expected around the time of IUD insertion.
But if pain during sex persists well beyond the initial recovery period, suddenly appears after a period without symptoms or progressively becomes worse, it deserves further evaluation.
One possibility is a change in the position of the device.
An IUD can occasionally become displaced, embedded or partially expelled.
Ultrasound can be used to assess IUD position when symptoms such as pelvic pain or abnormal bleeding raise concern (Nowitzki et al., 2015).
The important point is that pain does not prove that the IUD has moved.
It simply means that the symptoms deserve to be understood rather than dismissed.
When Could the IUD Be Involved?
There are several situations in which the IUD needs to be considered.
IUD malposition
A correctly positioned IUD sits within the uterine cavity.
If it becomes displaced, embedded or partially expelled, some women may experience pelvic pain, abnormal bleeding or changes in their usual symptoms.
However, not everyone with a malpositioned IUD will have obvious symptoms.
This is why an examination or imaging may be necessary when there is concern.
Infection
Pelvic inflammatory disease can cause pelvic pain and pain during sex.
If you also have fever, unusual vaginal discharge, abnormal bleeding or feel generally unwell, seek medical evaluation.
These symptoms should not simply be blamed on the contraceptive device.
Other pelvic conditions
Pain during sex can also occur with endometriosis, ovarian conditions, pelvic inflammatory conditions and other causes of chronic pelvic pain.
An IUD may therefore be present at the same time as the actual cause of the pain.
Does the Type of IUD Matter?
Broadly, IUDs fall into two categories: copper IUDs and hormonal IUDs.
Copper IUDs do not contain hormones and can increase menstrual bleeding and cramping, particularly during the early months after insertion.
Hormonal IUDs release levonorgestrel and commonly change menstrual bleeding patterns over time.
Research comparing the sexual effects of different IUDs is still developing.
There is no reliable rule that says one type will cause painful sex while another will not.
Your experience can also be influenced by pre-existing pelvic pain, menstrual symptoms, vaginal health and other factors unrelated to contraception.
Where Does the Pain Occur?
One of the most useful things you can do is pay attention to where the pain happens.
Pain at the vaginal entrance
If pain starts as penetration begins, possibilities include pelvic-floor muscle overactivity, dryness, irritation, vulvar conditions and other causes.
This type of pain can sometimes lead to involuntary tightening of the pelvic-floor muscles.
Deep pelvic pain
Pain deeper inside the pelvis has a different range of possible causes.
Endometriosis, infection, ovarian conditions and other pelvic disorders should be considered alongside possible IUD-related problems.
Physiotherapy may help with musculoskeletal contributors, but deep pelvic pain should not automatically be labelled a pelvic-floor problem.
Pain after sex
Some women feel fine during intercourse but develop aching or cramping afterward.
The pattern matters.
If this happens repeatedly, especially when accompanied by bleeding, discharge or worsening pelvic pain, discuss it with a healthcare professional.
Can Pelvic-Floor Muscles Contribute to Pain?
Absolutely.
The pelvic floor is a group of muscles at the base of the pelvis.
These muscles contribute to bladder and bowel control, pelvic support and sexual function.
They also respond to pain.
Imagine that penetration has hurt several times.
Before the next attempt, your body may start anticipating that discomfort.
The pelvic-floor muscles can tighten automatically as part of a protective response.
That can create a cycle:
Pain → protective tightening → reduced relaxation → more discomfort.
This is a physical response.
It does not mean that the pain is imaginary or “just psychological.”
How Can Physiotherapy Help?
Once an appropriate medical assessment has ruled out an urgent or structural cause, pelvic-health physiotherapy can be useful when muscles and movement are contributing to the pain.
A physiotherapist may assess:
- Pelvic-floor muscle tone
- Ability to contract and relax the pelvic floor
- Breathing patterns
- Abdominal and pelvic coordination
- Hip mobility
- Muscle tenderness
- Movement patterns
- Activities or positions that reproduce pain
The goal is not to immediately prescribe exercises.
First, the physiotherapist needs to understand why the muscles may be reacting this way.
Treatment is then built around the findings.
Do You Always Need Kegel Exercises?
No.
This is an important distinction in pelvic-health physiotherapy.
Kegel exercises strengthen the pelvic-floor muscles, but painful sex does not automatically mean that the muscles are weak.
In some women, the pelvic floor may already be excessively active and have difficulty relaxing.
In that situation, repeatedly squeezing the muscles may not be the first thing you need.
Treatment may instead focus on:
- Pelvic-floor relaxation
- Diaphragmatic breathing
- Improving pelvic-floor coordination
- Gentle mobility
- Reducing protective muscle tension
- Gradual exposure to previously painful movements
- Strengthening later, if weakness is identified
A 2025 systematic review found considerable variation in pelvic-floor muscle training program used for women with dyspareunia, reinforcing the importance of individualizing treatment rather than prescribing one exercise to everyone (Cavalcanti et al., 2025).
Can Physiotherapy Actually Reduce Pain During Sex?
Research suggests that physical therapy can help some women with dyspareunia.
A systematic review and meta-analysis found improvements in pain and quality of life following several physical therapy interventions, although the studies differed in their treatment approaches and methods (Fernández-Pérez et al., 2023).
Another systematic review examining pelvic-floor physical therapy for pelvic-floor hypertonicity found evidence of potential benefit, while also noting limitations in the available research (van Reijn-Baggen et al., 2022).
This is why treatment should be based on your individual symptoms rather than a generic “pelvic-floor exercise” programme.
Can Changing Sexual Position Help?
It can sometimes make a noticeable difference.
If your pain occurs mainly with deeper penetration, changing the depth or angle may reduce the amount of pressure placed on sensitive structures.
You can also slow down, communicate with your partner and stop if pain begins.
These strategies do not diagnose or treat the underlying cause.
They simply reduce the likelihood of repeatedly provoking pain while you work out what is happening.
You should never feel that you have to continue intercourse simply because you have an IUD.
What Can You Do at Home?
If the pain is mild and you are waiting for an assessment, a few simple approaches may help you avoid aggravating the problem.
Do not repeatedly push through pain
Pain is useful information.
Continuing an activity that consistently causes significant pain can reinforce protective muscle tension.
Pay attention to breathing
Some people unconsciously hold their breath or tighten their abdomen when anticipating penetration.
Slow, comfortable diaphragmatic breathing can help reduce unnecessary muscle tension.
Give your pelvic floor permission to relax
If your pelvic floor is overactive, constantly squeezing it is unlikely to be helpful.
Focus on gentle relaxation rather than repeatedly performing strengthening exercises without an assessment.
Keep a symptom diary
Record when the pain occurs, where you feel it, which positions trigger it and whether symptoms continue afterward.
Also note bleeding, discharge or other pelvic symptoms.
This information can be extremely useful during a medical or physiotherapy assessment.
Should You Have Your IUD Checked?
If painful sex started soon after insertion, appeared suddenly after a period without symptoms or is progressively worsening, speak with your healthcare provider.
An IUD position assessment may be appropriate if the symptoms suggest a possible device-related problem.
Ultrasound is an established method for assessing IUD position when there is concern about pelvic pain, abnormal bleeding or missing strings.
Do not try to reposition or remove the IUD yourself.
When Should You Seek Medical Care?
Pain during sex deserves medical attention when it is persistent, severe or getting worse.
Seek prompt medical care if you experience:
- Severe or increasing pelvic pain
- Fever or chills
- Unusual vaginal discharge
- Heavy or unexpected bleeding
- Fainting or severe dizziness
- A positive pregnancy test or possible pregnancy
- Sudden severe abdominal pain
- Concern that the IUD has moved or partially expelled
These symptoms may indicate a problem that requires medical evaluation rather than physiotherapy alone.
A Physiotherapy Approach to Painful Sex
A good pelvic-health physiotherapy assessment starts with questions, not exercises.
When did the pain begin?
Where exactly do you feel it?
Does it happen with initial penetration or deeper penetration?
Does a particular position trigger it?
Does the pain continue after sex?
Do you notice tension in your abdomen, hips or pelvic floor?
The physiotherapist can then assess relevant movement and muscle function.
If pelvic-floor overactivity is contributing, treatment may focus on helping those muscles learn to relax and coordinate more effectively.
If weakness is present instead, strengthening may become part of rehabilitation.
The treatment should match the problem.
Lesser-Known Fact
An IUD does not have to be physically displaced for a woman to experience pain after getting one.
The timing of a new health intervention can sometimes change how the body responds to an experience.
For example, if insertion was uncomfortable or pelvic cramping was significant afterward, a person may become more protective of the pelvic region during subsequent penetration.
That protective response can involve involuntary pelvic-floor tightening.
In such cases, the pain can persist even when the IUD itself is correctly positioned.
This is one reason that evaluating both medical and musculoskeletal factors can provide a more complete picture.
When Should Physiotherapy Be Considered?
Pelvic-floor physiotherapy may be worth considering when:
- Medical causes of pain have been assessed
- The IUD has been confirmed to be appropriately positioned when necessary
- Pelvic-floor tension appears to contribute to symptoms
- Pain continues despite treatment of an underlying medical problem
- Penetration triggers involuntary muscle tightening
- Hip, abdominal or pelvic movement appears to influence symptoms
Physiotherapy is not about forcing painful penetration or “strengthening through” discomfort.
It is about understanding how the muscles are behaving and helping the body gradually return to comfortable movement and sexual activity.
An IUD can be associated with pelvic or sexual pain in certain situations, but painful sex should not automatically be blamed on the device.
The timing of symptoms, IUD position, infection, underlying pelvic conditions and pelvic-floor muscle function can all matter.
When pelvic-floor tension is contributing to painful penetration, a pelvic-health physiotherapist may help address muscle relaxation, coordination and movement-related factors.
Pain during sex is not something you simply have to tolerate. Understanding the underlying cause is the first step toward making intimacy more comfortable.
Final Thoughts
Can an IUD cause pain during sex?
It can be associated with pelvic or sexual pain in certain circumstances, but an IUD is not automatically the cause of painful intercourse.
The timing of symptoms, IUD position, infection, underlying pelvic conditions and pelvic-floor muscle function all need to be considered.
From a physiotherapy perspective, pelvic-floor overactivity and difficulty relaxing can contribute to painful penetration, particularly when the body has developed a protective response to previous pain.
But physiotherapy should not replace medical assessment when an IUD complication, infection, pregnancy-related problem or another gynaecological condition is possible.
Pain during sex is not something you simply have to tolerate.
Finding the underlying contributor is the first step toward making intimacy more comfortable, restoring confidence in movement and helping you return to a more comfortable sex life.
Can an IUD cause pain during sex?
An IUD can be associated with pelvic or sexual pain in some situations, but research does not show that IUDs routinely cause painful sex. IUD position, pelvic conditions, infection and pelvic-floor muscle tension can all be relevant.
Why does sex hurt after IUD insertion?
Some cramping can occur around IUD insertion, but persistent, severe or worsening pain should be evaluated. IUD position, infection and other pelvic conditions may need to be considered.
Can an IUD cause deep pain during sex?
Deep pain during intercourse can have several causes, including pelvic conditions, infection or an IUD-related problem. Persistent deep pain should be assessed rather than automatically attributed to the IUD.
Can pelvic-floor physiotherapy help painful sex?
Pelvic-health physiotherapy may help when pelvic-floor muscle tension, poor relaxation or other musculoskeletal factors contribute to painful sex. Treatment should be based on an individual assessment.
Do Kegel exercises help painful sex?
Not necessarily. Painful sex can sometimes involve an overactive pelvic floor, where relaxation and coordination may be more appropriate than strengthening alone.
