I have been trying to research IUI treatment and have just ended up even more confused. Some websites say one thing and then the next totally blows the previous out of the water. So, what can IUI be used for? To bypass problems with the fallopian tubes? Contradictory information on that. Is it used when someone ovulate normally? I think the actual NHS site is the worst as they sort of word it as a forbidden choice, yet others recommend it for all sorts. Just after some clarification I suppose.
