& motility are variable.
Welcome to XXXXXXX
Sperm count & motility can vary in the same person from time to time. So single semrn analysis is never the final result. You can repeat it once more after a week or two after 2-3 days of abstinence to know exact status.
Coming to your semen analysis
report, volume of 5ml is good(high) as it can compensate for low count & motility. But rarely high volume can indicate infection of prostate
which can cause low motility. If your second semen analysis report comes same, you can get one semen culture done to rule out infection.
Apart from infection, varicocele
(backflow of blood in testes) is a treatable cause which can cause low motility. You can get yourself examined by urologist/andrologist to rule out varicocele if second semen analysis shows low motility.
Other than that hormonal
disturbances can cause low motility, but that is not very common.
Apart from treating infection, varicocele & hormonal disturbances, treatment of low motility is emperical. It consists of avoiding hot baths, avoiding exposing genitalia to high temperatures, avoiding smoking
& alcohol and taking diet rich in antioxidants: plenty of fruits & dry fruits OR nutritional supplements.
So one simple plan for you can be: lifestyle modification as mentioned above for two weeks & recheck semen analysis after two weeks. Only if results are abnormal, to go for investigation & treatment of the same.
Your viral fever
episode might be one cause if fever was prolonged (>101`F for more than 48 hours or so). If fever was more than 48 hours or so, please repeat semen analysis after 3 months rather than two weeks.
Hope this helps you.
Let me know if you have other concerns.
Wish you good health.
