Hello
One by one I am answering , so please read it carefully:
Volume 2 ml ( normal 2-6 ml but depending abstinence i.e.if longer period more in volume).
Color Whitish ( normally grey whitish ,but in your case it is normal ).
Liquefaction time 30 minute ( normal 30-60 minute).
Total super count 50.0 million/ml ( normal 60 120 million/ml , in your case somewhat low ,but this is not a cause of concern because NORMAL fertility is associated with sperm counts >48 million.ml).
Motility active 3% ( normal 100 % , normal fertility is associated with motility >63 %, so in your case it is too low )
Pus cells 5-7 .hpf( normal 0-5 , this is not a cause of concern and just antibiotics for 3-4 days will cure ).
In your case you didn't mention about the MORPHOLOGY of sperm , that is also important ,so either upload on this site or consult an
INFERTILITY specialist and get his opinion.
Good luck.
