Hi!
Here is a great page for information on semen analysis: http://www.ivf-infertility.com/infertility/investigations/male/semen.php
It looks like they didn't give you a count (total number of sperm), and that the motility is low. This would be worriesome if you weren't planning IUI. When you do IUI, they will do a sperm wash, this concentrates the good forwardly motile sperm, so usually the post wash motility is higher. They will then put the sperm directly into the uterus (by passing the cerivix and giving them a better chance). I don't know what the count is, but the motility is OK--as long as you are doing IUI!
If the IUIs don't work, the next step to consider is ICSI (intracytoplasmic sperm injection) in which the sperm is injected directly into the egg. This is an IVF procedure, and is significantly more expensive than IUI, so lets hope the IUI works for you!
Good luck!
