Is IUI painful? What to expect
For most women IUI is a short, mildly uncomfortable step, similar to having a cervical smear taken; it is done awake, without anaesthesia. Washed sperm is placed in the womb through a soft, thin catheter, and you can go back to normal activities the same day.

In these videos our fertility specialist explains who needs IUI and shows what is used during the procedure.
What does IUI feel like?
Most women describe it as uncomfortable rather than painful. Opening the speculum gives a feeling of pressure, and some women notice a short, period-like cramp while the soft tube is guided into the womb. Light spotting afterwards is possible. If you have found internal examinations very hard before, tell the team, so they can take it slowly.
Who needs IUI?
- Couples with unexplained infertility, after the basic tests are normal.
- A mild problem with the sperm count or movement.
- Irregular ovulation, together with medicines to help an egg grow.
- Difficulty with intercourse, or using frozen sperm.
At least one fallopian tube must be open, which is why a tube test is usually done first.
IUI medicines
Some cycles use no medicines and simply time the IUI to natural ovulation. Others use tablets such as letrozole, or egg-growth injections, with scans to follow the follicle, and a trigger injection to time ovulation. Your doctor chooses the plan.
What is used during IUI?
- A speculum, to see the neck of the womb.
- A soft, thin IUI catheter, attached to a small syringe holding the washed sperm.
- The prepared sample, washed in the laboratory to concentrate the moving sperm.
On the day of the IUI
- The husband gives a semen sample, usually at the clinic, after a few days without ejaculation as advised.
- The lab washes and prepares the sample, which takes about an hour or so.
- You lie on the couch as for an internal check, the speculum is placed, and the soft tube is passed into the womb.
- The washed sperm is placed gently, and the tube and speculum are removed.
- You may rest for a few minutes before going home.
Tips to make IUI more comfortable
- Wear loose, comfortable clothes.
- Breathe slowly and keep the muscles of your thighs and bottom relaxed; tensing up makes the speculum feel tighter.
- A full bladder is sometimes asked for, so the womb can be seen on scan; follow your clinic's advice.
- Tell the doctor at once if anything hurts, so they can stop or adjust.
After the IUI
Mild cramping for a short while and a little spotting are common and settle on their own. You can walk, work, travel and carry on with daily life. Some couples are given progesterone support or other medicines after the IUI; take them only as advised. A pregnancy test is usually done about two weeks later.
When to call the clinic
- Pain that is getting worse rather than better.
- Fever or a bad-smelling discharge in the days after.
- Heavy bleeding.
- After injections: a swollen, tight belly, breathlessness, vomiting or passing very little urine.
These are uncommon, but they need to be checked quickly.
If it was hard last time
Some women have a tight or tilted neck of the womb, or have found a previous IUI difficult. Let the team know beforehand. They can use a different catheter, take more time, or use gentle steps to straighten the neck of the womb, so that the next IUI goes more easily.
How IUI compares with other fertility procedures
IUI is one of the simplest steps in fertility care. There is no needle into the ovary, no anaesthesia and no stay in hospital. A tube test such as an HSG, which is often done before IUI, can feel more crampy, because dye is passed through the tubes. Egg collection in IVF is done under short anaesthesia, so it is not felt at the time. Knowing this helps many women go into the IUI day calmly.
Does pain affect the result?
A little cramping during or after the IUI does not lower the chance of pregnancy. Spotting from the neck of the womb is also harmless. What matters most is the timing, the washed sample and the health of the tubes and eggs.
The procedure itself takes only a few minutes. Read the full guide to IUI treatment.
