There’s no minimum amount of sperm required for testing. Your results will tell you if your sample has a very low sperm count or no sperm present.

If there are no sperm present in your sample, your results will not be viable for freezing. But even if you have a very low sperm count, your sample is viable for freezing, and freezing may be especially important for those who have poor semen parameters.

For use in IUI, you’ll need a post-thaw total motile sperm count of around 8–10 million. For use in IVF, there is no minimum amount of sperm. The latest techniques used in IVF — called ICSI — only need a single sperm to inject directly into the egg, so a sample with any motile sperm can be used multiple times.
