How many IUI cycles should we try before moving to IVF?

There is no single number for everyone, but many specialists suggest around three to four well-timed IUI cycles for couples where IUI is a reasonable option. Most of the pregnancies that happen with IUI tend to occur within the first three or four cycles, and the chance per cycle tends to drop after that. The decision depends on several things: the woman's age and ovarian reserve (AMH, antral follicle count), whether both tubes are open, the semen parameters after washing, how many years you have been trying, and how you responded to medication in each cycle. For women in their late 30s or older, or where sperm counts after washing are low, doctors often suggest moving to IVF sooner. At 34 with good tests, completing a few IUIs is often reasonable, but your concern about time is valid and worth raising. It also matters whether earlier cycles were truly 'good' cycles, with a good follicle response, correct timing and adequate sperm. If something went wrong, the cycle may not count in the same way. Sit down with your doctor and ask them to review your cycles so far and explain the expected chances of continuing IUI compared with moving to IVF. Seek review sooner if you have irregular cycles, known endometriosis, or a tubal concern.
