What is IUI?
Intrauterine insemination (IUI) involves placing specially prepared sperm directly into the uterus close to the time of ovulation, shortening the distance sperm must travel. It is generally simpler and less invasive than IVF and is often considered as an earlier step for suitable couples.
Who IUI may suit
- Mild male-factor infertility
- Unexplained infertility
- Certain ovulation issues (often combined with ovulation induction)
- Couples preferring a less invasive first option
The process
The cycle is timed to ovulation, sometimes with medication to support egg development, and monitored by ultrasound. The insemination itself is a brief, usually painless clinic procedure that does not require sedation.
Success and next steps
Success per cycle is generally lower than IVF and depends on age and the underlying cause. Several cycles may be tried before moving to IVF if needed. Your specialist will advise how many cycles are reasonable for your situation.
When to see a specialist
Couples who have been trying to conceive without success — generally a year, or six months if the woman is over 35 — should consider a fertility assessment to discuss whether IUI or another approach is appropriate.
