Above 5 million sperm/ml. If the total motile count after being processed is less than 5 million, success is unlikely, and other techniques such as IVF should be considered. Keeping this in mind, we can say that sperm counts between 20-30 million/ml of semen before washing and subsequent IUI are ideal.
What is the ideal motile sperm count for IUI?
