Hi, thanks for using healthcare magic
Sperm analysis looks at different (but not all) aspects of the semen.It is important to remember that men with normal semen results may have difficulty conceiving and men with abnormal results may not.
In terms of your results: normal volume is greater than 2 mls so, 2.5ml is fine.
Sperm count:45 mill per ml is good, less than 20 mill per ml is low
In terms of motility:at least 50% should be mobile, in your results 35% are mobile so it is slightly below the norm.
Other important aspects would be the shape of the sperm and whether they are in clumps.
IUI would improving chances of conception- it involves placing the sperm directly into the uterus
I hope this helps
