Frequently asked questions on important topics / How does smoking affect reproductive health in men?

Although only a small number of studies have looked at the relation between smoking and erectile dysfunction, research findings suggest that smoking may be associated with an increased risk for this condition. More studies are needed, however, before researchers can conclude that smoking is causally related to erectile dysfunction.

Research also suggests that cigarette smoking may affect the amount of semen and sperm produced and adversely affect sperm quality.
