Hi thanks for contacting HCM...
Here cause for immotility and 
abnormal sperm morphology has to be treated....
First if you have habit of smoking and alcohol then avoid it....
Heat exposure excessive  avoided.
Hot shower limited...Tight undercloths not wear ...It should be somewhat loose...
Stress can affect it...So avoid stress , for that 
psychiatric counselling session can be done....
For 
semen analysis semen should collected with three days abstinence ...
Otherwise false result can be there.
Avoid too much frequent sex that can lead alter result.
If you are taking hormonal supplement like 
anabolic steroid it can affect result.
Heavy metal exposure can be harmful 
So for that if needed sea foods and organic food avoided.
Rule out vitamin and 
mineral deficiency....
Vitamin A,C , E and antioxidant useful.
L carnitin tablet help in increasing motility...
Even if with full investigation and treatment report abnormal then assisted reproductive technique need to be used for conception.
Take care.
