Can a perfectly healthy male have low sperm count?

Q: What are the chances of a healthy male having a low sperm count or sperms with less mobility? Can it happen to any body? Are there any symptoms for the same? How can it be diagnosed?

A:A low sperm count or low motility can be present in an otherwise normal individual and can be asymptomatic. Hence it is advisable to get a semen analysis done if unprotected intercourse for one year does not result in a pregnancy.
