Intrauterine Insemination (IUI) is a fertility procedure where washed and concentrated sperm are placed directly into a woman’s uterus during ovulation. This improves the chances of fertilisation by placing the healthiest sperm closer to the egg at the most fertile time.
IUI is often chosen as a first-line treatment for couples who need a gentle boost in their fertility journey — offering improved timing, better sperm access, and a non-invasive alternative to more advanced procedures.
IUI is a timed procedure that involves:
It’s a painless, outpatient procedure that takes only a few minutes but can significantly enhance the chances of conception in the right patient profile.
IUI is most effective in:
Note: IUI is not suitable for women with blocked fallopian tubes or severe endometriosis.
Your cycle may be monitored naturally or induced with medications like Letrozole or gonadotropins to promote the development of one or two mature follicles.
Ultrasounds help pinpoint the day your ovary will release an egg. A trigger injection (HCG) may be given to time ovulation.
The male partner provides a semen sample, which is then processed in a lab to remove debris and isolate fast-moving, healthy sperm.
On the day of ovulation, a thin catheter is used to place the prepared sperm into the uterus. This is done in the clinic, takes less than 5 minutes, and feels similar to a pap smear.
You may be advised to take luteal support medications and return after two weeks for a pregnancy test.
IUI is:
It’s also a good emotional “starting point” for couples unsure about more advanced treatments.
Careful candidate selection to avoid unnecessary cycles
Accurate ovulation timing using ultrasound and hormonal tracking
Personalised stimulation protocols for better follicle response
Sperm processing by expert embryology teams
Minimally invasive with no anaesthesia needed
Focused emotional support, especially in repeat cycles
Generally, 3–4 well-timed cycles are recommended before considering IVF, especially in women under 35.
Most women report little to no pain — just mild cramping or discomfort similar to a pap smear.
IUI success rates vary from 10–20% per cycle, depending on age, diagnosis, and cycle response. It’s best used in selected cases.
Absolutely. IUI does not require rest or downtime, although light activity for the day is often encouraged.

If ovulation is induced, there is a small chance of multiple follicles developing, which may increase the twin rate slightly. This is closely monitored and controlled.
