Why you might see this term

IUI may be considered for different family-building situations. Assessment of ovulation, tubal patency and the sperm sample helps establish suitability.

What to keep in mind

It is different from IVF: fertilisation still takes place inside the body. Suitability and success depend on the individual circumstances.
