Garth is a heavy cigarette smoker. what types of sexual problems can he possibly experience due to smoking?

Smoking can also hinder sexual performance, even when the smoker is initially in the mood. Smokers are more likely to have lowered sperm mobility and other issues which may make impregnating a partner more difficult. This may be in part due to the lack of blood flow smokers experience due to smoke inhalation and decreased lung function, although researchers are trying to determine all the ways tobacco use can affect sexual function.
