The success rate of IUI with the husband's sperm is 12-16%, while it increases to 18-22% if donor sperm is used. The chances of getting pregnant are cumulative, that is, they increase after several cycles, with a maximum of fourth cycles before moving on to IVF. In the fourth cycle, women are expected to have a 31-35% chance of achieving pregnancy.
