How high a sperm count is needed for IUI?
A count above one million washed appears necessary for success, with a significant reduction in pregnancy rates when the inseminated is count is lower than 5-10 million (in other words, in most cases one should consider 5 million a lower limit for success, 10 million for cost-effective). Higher success rates are with washed counts over 20-30 million, while increasing counts over 50 million did not appear to offer advantage.
A count above one million (after sperm preparation) appears necessary for success, with a significant reduction in pregnancy rates when the inseminated is count is lower than 5-10 million (in other words, in most cases one should consider 5 million a lower limit for success, 10 million for cost-effective). Higher success rates are with washed counts over 20-30 million, while increasing counts over 50 million did not appear to offer advantage.
