Thanks for your query.Based on the facts that you have posted it appears that your semen analysis
is well within normal limits as per WHO standards .
As regards PH of 8.5 reveals that semen is alkaline and it is also normal ,you do not require any medication to reduce the pH .
Since you have not posted entire report especially presence or absence of Leukocytes
in semen I can not make any comments regarding prostatic infection.
Thanks and Regards.
