Overview
What is IUI?
Intrauterine insemination (IUI) places washed, concentrated sperm directly into the uterus around the time of ovulation. It shortens the distance sperm need to travel and is less invasive than IVF.
IUI can be done in a natural cycle or with mild ovulation support. Whether it suits you depends on your assessment: the fallopian tubes need to be open, and sperm quality needs to be adequate.
Benefits
- Less invasive and simpler than IVF
- No anaesthetic needed
- Natural cycle or mild stimulation
- Ultrasound monitoring to time it precisely
Is it right for you?
Often a good fit for
- Unexplained infertility with open tubes
- Mild sperm concerns
- Ovulation difficulties such as PCOS, with ovulation support
- Difficulties with intercourse
We may advise waiting, or another option, with
- Blocked or damaged fallopian tubes
- Severe sperm concerns, where IVF or ICSI is usually advised
- Some cases of advanced age or low ovarian reserve, where IVF may be more effective
Suitability is always confirmed in person, at your consultation.
How it works
01
Monitoring
Ultrasound scans track the growing follicle, with medicine to support ovulation if needed.
02
Trigger
When the follicle is ready, an injection may be used to time ovulation.
03
Sperm preparation
The sample is washed and concentrated in the laboratory on the day.
04
Insemination
A fine, soft catheter places the sperm in the uterus. It takes a few minutes and feels similar to a smear test.
Before and after
Before your visit
- Attend every monitoring scan
- Take any prescribed medicines exactly as directed
- Follow the sample instructions for your partner
Aftercare
- Rest briefly, then go about your normal day
- Avoid strenuous exercise for a day or two
- Take a pregnancy test only on the date we give you
Possible side effects
- Mild cramping or light spotting
- A small chance of twins when ovulation medicines are used
- Rarely, infection
Every risk is explained before you decide. Results vary from person to person.
IUI: your questions
How many IUI cycles should we try?
Usually up to three or four. If IUI has not worked by then, we review whether IVF would give you a better chance.
Is IUI painful?
Most women feel mild cramping at most. No anaesthetic is needed.
