Understanding IUI success rates helps couples set realistic expectations for fertility treatment. In India, IUI success rates average 10-15% per cycle, but can reach 50-70% after multiple attempts. Age, sperm quality, and overall health significantly impact outcomes. Most specialists recommend 3-4 cycles before considering alternatives.
