Thanks for your query,based on the facts and report of your semen analysis
that you have posted it appears that your semen parameters are within normal range of WHO standards
,However the agglutination of sperm is suggestive of either due to infection or presence of Anti Sperm antibodies
. which could be the cause of infertility
Please get your blood tests for presence of anti sperm antibodies and semen culture done to rule out presence of infection done .
Further treatment will depend upon findings of these tests.
