How IUI works
IUI involves preparing and concentrating washed sperm and placing it directly into the uterine cavity around the time of ovulation. This bypasses the cervix and shortens the distance the sperm must travel to reach the egg in the fallopian tube.
Most cycles include controlled mild stimulation with oral or low-dose injectable medication to recruit one to three mature follicles, ovulation trigger when follicles reach optimal size on ultrasound, and the IUI procedure itself which takes around 10 minutes in the consulting room.
Who should consider IUI
IUI is best suited to specific clinical situations:
- Mild male factor infertility with adequate total motile sperm count after preparation
- Cervical factor infertility (rare today with modern diagnostics)
- Unexplained infertility in younger women with patent tubes — typically up to three cycles before moving to IVF
- Mild endometriosis in women with patent tubes and acceptable ovarian reserve
- Anovulation (especially PCOS) where ovulation induction alone has not produced pregnancy
- Same-sex couples and single women using donor sperm (ICMR ART Act-compliant pathway)
When we recommend against IUI
We will counsel against IUI and recommend moving directly to IVF when:
- Severe male factor infertility (total motile sperm count below 5 million after wash)
- Bilateral tubal blockage or significant tubal damage
- Advanced female age (≥38) with diminished ovarian reserve
- Severe endometriosis or stage III-IV disease
- Three failed appropriately-timed IUI cycles
Offering IUI in these situations wastes precious time and resources. Our priority is to get you to the right treatment at the right time.
Realistic success rates
Per-cycle success rates with IUI typically range from 8 to 18 percent depending on age, diagnosis, and male factor. Cumulative pregnancy rates after three cycles can reach 30 to 40 percent in carefully selected couples.
We share honest, age-stratified outcomes — not industry-best statistics from cherry-picked cohorts. If your individual factors predict low IUI success, we will tell you upfront and recommend IVF as the more appropriate next step.
The IUI cycle, step by step
- Day 2–3 baseline scan and bloods — assess ovarian reserve and rule out cyst
- Stimulation — 5 to 12 days of oral letrozole, clomiphene, or low-dose gonadotrophins
- Monitoring scans — track follicle growth and endometrial development
- Trigger — when one to three follicles reach 17–20 mm, hCG or GnRH agonist trigger
- Sperm sample — collected 2 hours before procedure, washed and prepared in the andrology lab
- The IUI — soft catheter through the cervix into the uterine cavity, takes minutes
- Two-week wait — luteal support if indicated, pregnancy test 14 days after IUI
