Does sperm count (including % active sperms) get affected by dengue fever? I had dengue fever detected on 15th October 2012. Just 2 days before, I got semen analysis done, and the count was fine. (74m/ml, 60% active motile). During dengue, my platelet count minimum was 0000, and therefore there was no need for external platelets. Now, I have fully recovered. I got my semen analysis done again (3 times) and all the time there are 1m/ml and NIL motile. Apart from dengue, I cannot think of any other thing that may have caused this. Please suggest. Thanks.
