Besides age, what are some other factors that can affect a man's fertility?

Dr. Clifford Librach, MD, FRCSC, FACOG(REI)'s Response

Heavy cigarette smoking has a negative impact on male fertility. Cigarette smoking can affect sperm count (number of sperm) and sperm motility (ability to move or travel in the woman's reproductive tract).

Significant alcohol consumption can reduce sperm production and testosterone secretion. The drop in testosterone can affect sex drive and lead to impotence.

Some medications can also reduce sperm count. There are often available alternatives that don't have the same effect. If you have questions about a specific medication you are taking, talk to your family doctor.

Heavy caffeine use may have an impact on sperm production. Finally, prolonged exposure to heat in a steam room or sauna can have an impact.
