Thanks for your query.Your sperm analysis is well within normal limits except the presence of 45-50 pus cells.This is suggestive of infection mostly in Seminal Vesicle
or Prostate .Please consult some Urologist
for clinical examination and get your Ultrasound
scanning done to confirm the diagnosis.Please take some antibiotics like Augmentin after consulting your family Physician .Repeat your semen analysis
after a month to confirm whether infection has subsided or not?
There is no reason for you not being a fertile.and fertility is not affected nor dependent on profession of a person You can consult some Infertility
specialist for proper evaluation and advice.So do not worry about it
