Hey Willie, welcome to the forum. I can understand why you and your wife are feeling a bit uncertain, fertility decisions can be tough and emotional.
About IUI, yeah, the success rate is usually around 10–20% per cycle, depending on factors like age, cause of infertility, and overall health. Some couples do several rounds before seeing results, while for others, it might not work at all.
It might help to speak with a fertility specialist to get a clearer picture based on your wife’s specific situation, like hormone levels, ovulation patterns, and any other underlying issues. Sometimes they suggest going straight to IVF if the chances with IUI are low.
Wishing you both the best with whatever path you decide to take.
