Have you just had an IUD inserted and are wondering when to resume intercourse? Does your partner feel anything during sex? Do you have stomach pains after sex? These questions come up all the time in gynecologists' offices and on forums. Most women who have an IUD (intrauterine device) worry at one point or another about its impact on their sex life. To cut to the chase, you can have intercourse almost immediately after insertion (recommended time of 3 days), but Contraceptive effectiveness varies depending on the type of IUDAs for the risk of intercourse dislodging the IUD, it is minimal but not completely zero. This article answers all your practical questions about sex with an IUD, without any waffle.
The main thing to remember
- The recommended time after installation is 3 days without intercourse (not 2 weeks, that's a myth)
- Contraceptive effectiveness : immediate for the copper IUD, 7 days waiting for the hormonal IUD
- Sexual intercourse almost never move the IUD (it is in the uterus, not in the vagina)
- Neither you nor your partner should feel the IUD itself, only the wires sometimes
- Overall eviction rate: 8-10% over 3 years, especially the first few months
- Pain after intercourse = warning sign possible (displacement, infection, ectropion)
- Light bleeding is common in the first few months, but repeated bleeding after intercourse warrants consultation.
How Long Should I Wait After IUD Insertion Before Having Sex?
This is the first question 90% of women ask after getting their baby fitted. Answers vary depending on the source, creating legitimate confusion.
What Health Authorities Say
Official French (HAS, CNGOF) and international (WHO, Planned Parenthood) recommendations do not set no mandatory abstinence period after an IUD has been inserted. Technically, you can have intercourse as soon as you feel physically ready.
Why do some practitioners recommend waiting 3 days?
In France and Quebec, many gynecologists advise avoiding intercourse (and tampons/cups) for 3 days after insertion as a precaution. This recommendation, although unofficial, is based on several common-sense arguments:
- Allow the cervix to close completely (slightly dilated after insertion)
- Reduce the theoretical risk of infection during this sensitive window
- Avoid aggravating cramps and bleeding, which often last 1 to 3 days.
- Allow the IUD to "stabilize" (although it is fixed upon insertion)
The most recent position (Planned Parenthood, 2024)
There is no formal medical contraindication to having intercourse immediately after insertion. You can resume intercourse whenever you wish, taking into account your personal comfort (pain, bleeding).
Many women naturally prefer to wait 24 to 72 hours simply because they do not feel physically comfortable immediately after the procedure.
The Myth of the "2 Week Wait"
Some forums suggest that you should wait two weeks. This information is false and not based on any reliable medical source. The origin of this confusion is probably related to the risk of expulsion (higher in the first few weeks) or the effectiveness time of the hormonal IUD (7 days), but certainly not to a risk related to the intercourse itself.
Difference Between Abstinence Delay and Contraceptive Effectiveness
Be careful not to confuse two separate things: the time before you can have intercourse and the time before the IUD is effective against pregnancy.
The Copper IUD as Emergency Contraception
A little-known but important point: the copper IUD can be used as emergency contraception after unprotected or poorly protected intercourse.
Remarkable effectiveness: 99% pregnancy prevention
The copper IUD can be inserted in the 5 days maximum after unsafe intercourse (or within 5 days after the estimated date of ovulation according to some sources). It is the most effective method of emergency contraception available, much more so than the morning-after pill.
This method requires a quick medical consultation to check for contraindications and to proceed with the installation, but it has the major advantage of then providing you with effective contraception for 5 to 10 years.
⚠️ Important for the hormonal IUD
If you have a hormonal IUD inserted and have intercourse within the next 7 days, you must use additional contraception (condom) or abstain.
The copper IUD is effective immediately. This is why it can be used as emergency contraception up to 5 days after unsafe intercourse. Despite its 99%+ effectiveness, pregnancy remains possible with an IUD, although rare.
Can the IUD move or shift during intercourse?
This is THE biggest fear for many women considering or having an IUD. The good news is that it's extremely rare.
Why Intercourse Almost Never Moves the IUD
To understand why this is so rare, you have to visualize the anatomy.
The IUD is in the uterus, intercourse takes place in the vagina
- The IUD measures 3 to 3,5 cm and is positioned inside the uterus, beyond the cervix
- Penetration during intercourse takes place in the vagina, which is approximately 8-10 cm deep
- The cervix (a firm, closed structure) separates the vagina from the uterus
- Penetration never reaches the uterus, so it cannot directly touch the IUD
- Only the IUD strings descend through the cervix and are accessible in the vagina
Several studies confirm that sexual intercourse does not cause IUD expulsion or displacement. Expulsions that do occur have other causes.
The Real Causes of IUD Expulsion
If sex doesn't displace the IUD, what can? The overall expulsion rate is 8 to 10% over 36 months, according to studies, with a peak risk in the first few months.
Signs Your IUD Has Moved
Even if it is rare, it is still important to know how to spot a movement.
Signs of expulsion or displacement
- You feel the hard plastic of the IUD in your vagina (normally you only feel the soft threads)
- The wires are much longer than before (the IUD has come down)
- You don't feel the wires at all anymore (the IUD has moved up or has been completely expelled)
- Unusual cramps, especially after menstruation
- Pain during intercourse which did not exist before
- Bleeding between periods which persist beyond 3 months
- Discovery of the IUD in your protection periodicals
If you experience these signs, consult quickly and use additional contraception in the meantime.
Is It Possible To Feel The IUD During Sex?
This question worries many couples. The answer depends on what you mean by "feeling the IUD."
What You Shouldn't Smell
Normal situation
- Neither you nor your partner should feel the IUD itself (the plastic T-shaped device)
- The IUD is 3 cm long and sits in the uterus, well beyond the penetration zone
- You should not feel any discomfort or foreign bodies during intercourse.
- If you or your partner feel something hard, it is abnormal and requires consultation.
IUD Threads: What Your Partner Can Feel
The only part of the IUD that is accessible during intercourse is the strings. These two nylon strings measure between 1 and 3 cm and protrude from the cervix into the vagina.
My partner feels the strings, is it serious?
No, it's not a big deal at all. About 10 to 20% of partners report feeling the IUD strings during intercourse, especially in the first few weeks. This doesn't mean the IUD is incorrectly positioned.
Why do some partners feel them and others don't?
- The threads are stiff for the first few weeks after placement, then soften and wrap around the cervix
- Certain positions (missionary, doggy style) bring the penis closer to the cervix
- Sensitivity varies from person to person
- The length of the threads can vary depending on the practitioner who cut them.
Solutions If Wires Are Bothering Your Partner
If your partner complains that the strings prick or bother them during sex, there are several options.
- Wait a few weeks : In 90% of cases, the threads soften naturally and the discomfort disappears on its own after 1 to 3 months
- Change position : Positions that limit deep penetration (spoon, closed-legged missionary) reduce contact with the cervix
- Have the wires cut : Your gynecologist can shorten the threads during a quick consultation. Be careful, however, as threads that are too short can be stiffer and sting more.
- Cut the threads flush with the collar : Radical solution that completely eliminates the discomfort, but makes removing the IUD more complicated (sometimes it is necessary to use forceps or a hysteroscopy)
- Wait for the 6-week check-up : During this consultation, the doctor can check the position and adjust the wires if necessary.

Lower Abdominal Pain After Sex With IUD
Pelvic pain after intercourse while wearing an IUD is not normal and deserves attention. There are several possible causes.
Causes Related to the IUD
1. Incorrectly positioned or displaced IUD
If the IUD has migrated downward, it can irritate the cervix. Sexual intercourse then causes painful micro-contractions of the uterus as it tries to expel the foreign body.
2. Arms of the IUD embedded in the uterine wall
In rare cases, the arms of the IUD may become partially embedded in the uterine wall. This can cause pain, especially during intercourse or menstruation. A hysteroscopy can confirm the diagnosis.
3. Incompatibility between the IUD and your uterus
If the IUD is too large for your uterine cavity, it exerts constant pressure on the walls. Orgasms and uterine contractions during intercourse amplify this pain.
Causes Not Related to the IUD
Sometimes the IUD is simply a scapegoat and the real cause lies elsewhere.
- Pelvic infection (salpingitis) : Pain + fever + foul-smelling discharge. The IUD does not increase the risk of infection except for the first month after insertion.
- Cervical ectropion : Fragile cells of the cervix that bleed and hurt when touched. Very common, benign
- Endometriosis : Chronic pelvic pain that sometimes existed before the IUD
- Ruptured ovarian cyst : Sudden pain on one side during or after intercourse
- Vaginal dryness : Lack of lubrication causing microtraumas
- Secondary vaginismus : Involuntary vaginal contractions after painful IUD insertion (rare but documented)
Signs that require prompt consultation
- Pain that gets worse instead of lessening after 3 months of use
- Severe pain during or after each intercourse
- Fever + pelvic pain
- Heavy bleeding after intercourse
- Sensation that something is "moving" or "scratching" during penetration
Bleeding After Sex With an IUD
Postcoital bleeding affects about 9% of women overall, and is slightly more common in the first few months after IUD insertion.
Normal Bleeding in the First Months
After an IUD is inserted, your body goes through an adjustment period of 3 to 6 months. During this phase, light bleeding after intercourse is common and benign. This bleeding outside of periods can occur at different times during the cycle.
Why this adaptation bleeding?
- The cervix remains slightly irritated for the first few weeks
- The endometrium (uterine lining) is disrupted by the presence of the IUD
- Uterine contractions during orgasm may cause light bleeding
- The copper IUD causes local inflammation that temporarily weakens the vessels
Bleeding That Should Alert You
Some bleeding after intercourse warrants consultation, even if it is often benign.
Common Causes of Postcoital Bleeding with IUD
- Cervical ectropion (19-34% of cases): Fragile cells of the cervix that bleed on contact
- IUD incorrectly positioned : Chronic irritation of the cervix
- Cervicitis (inflammation of the cervix): Benign infection often associated
- Vaginal dryness : Microtraumas during penetration
- Cervical polyps : Benign growths that bleed easily
Sexual Intercourse Before IUD Removal
This question comes up less often, but it is important if you are planning to have your IUD removed.
Should I abstain 24 hours before withdrawal?
There is no formal medical recommendation prohibiting intercourse 24 hours before IUD removal. However, two situations warrant consideration.
If you want to avoid pregnancy
Sperm can survive for up to 5 days in the female reproductive system. If you have unprotected intercourse within 5 days of IUD removal and ovulate shortly afterward, pregnancy is theoretically possible.
Recommendation : If you do not want to get pregnant after removal, use condoms for 5 days before removal, or start a new contraceptive 7 days before removal (pill, ring, patch).
If you want to get pregnant after removal
The return to fertility is immediate with the copper IUD, and very rapid (a few days to 3 months) with the hormonal IUD.
So you can have sex without contraception in the days leading up to the withdrawal if you are ready to conceive immediately. Some couples even use this strategy to maximize their chances of conception.
Intercourse After IUD Removal
Unlike insertion, there is no recommended period of abstinence after removal. You can resume intercourse as soon as you feel ready, usually immediately or within a few hours.
Removal is much less invasive than insertion and rarely causes prolonged pain. Some women experience mild cramping during removal, but this stops as soon as the IUD is out.
Changing an IUD: Managing the Transition
If you change your IUD (replacement at the end of its validity or switching from one type to another), managing sexual intercourse follows specific rules.
Same Day Pickup and Installation
In the majority of cases, the new IUD is inserted immediately after the old one is removed during the same consultation.
Recommendations for reports
- Wait 3 days after replacement before having intercourse (same rule as for classic insertion)
- If you are switching from a copper IUD to a hormonal IUD, use additional contraception for 7 days
- If you switch from a hormonal IUD to a copper IUD, you are protected immediately
- If you replace a copper IUD with a new copper IUD, protection is continuous and immediate
Time Between Removal and Insertion of a New IUD
Sometimes the IUD is removed without one being replaced immediately (technical problem, infection detected, need for reflection).
⚠️ Beware of the risk of pregnancy
If you have had unprotected intercourse within 5 days of IUD removal and do not have a new IUD inserted immediately, you risk pregnancy.
Solution: Start emergency contraception (morning-after pill) if you don't want to get pregnant, or start traditional hormonal contraception (pill, patch, ring) on the day of removal.
Check the Position of Your IUD Yourself
Many gynecologists recommend checking monthly that the IUD strings are still present and at the correct length. This self-check helps detect displacement early.
How to Check Your IUD Strings
Self-check steps (once a month after menstruation)
- Wash your hands thoroughly
- Sit or squat in a comfortable position
- Insert your index or middle finger into the vagina until you feel the cervix (a small, firm bump at the bottom of the vagina)
- Look for the two IUD strings sticking out of the cervix. They look like fishing line.
- Check that you can feel both wires and that they are roughly the same length as before
- Never pull on the wires (risk of expulsion)
Abnormal situations requiring consultation
- You don't feel the wires at all anymore
- The wires are much longer than before
- The wires are much shorter than before
- You feel the hard plastic of the IUD itself
- You feel one thread instead of two
Practical Questions About the IUD and Sex
A Fulfilling Sex Life with an IUD
The IUD is one of the most discreet and liberating forms of contraception available. Once the adjustment period is over (usually 3 to 6 months), most women no longer feel their IUD on a daily basis, let alone during intercourse. Fears of the IUD moving during sex are largely overestimated. Sexual intercourse almost never causes expulsion, unless the IUD was already in the wrong position to begin with.
If you experience pain during or after intercourse beyond the first few months, or if your partner constantly complains of discomfort from the strings, talk to your gynecologist. These problems almost always have a simple solution (adjusting the strings, checking the position, treating an ectropion). The IUD should never be a barrier to your pleasure or intimacy. You deserve contraception that works for you, not against you.
