Well, let's see--the answer is yes, indirectly, smoking causes impotence (erectile dysfunction) in a number of ways:

1) smoking can and does lead to vascular (blood vessel) narrowing due to the effects of nicotine and other ingredients causing vasoconstriction and plaque build up, which adversely affects the circulatory system to the point where blood supply to certain organs is compromised. In the case of the penis, this means less full, or absent erections.

2) smoking can and does lead to cardiac disease due to coronary artery narrowing, which causes compromised blood supply to the heart muscle, especially during exertion, so there can be chest pressure, shortness of breath and risk of heart attack during sex, so that can lead to erectile dysfunction.

3) smoking can and does lead to lung disease due to damage to the small airways resulting in decreased elasticity of the bronchial tree causing shortness of breath, which is exacerbated by exertion, so that can lead to erectile dysfunction.

4) smoking can and does lead to lower testosterone levels, which can affect sexual drive and result in erectile dysfunction

5) smoking can and does lead to a number of cancers, which are sometimes treatable, sometimes not, but almost always affect sexual drive and various treatment methods cause erectile dysfunction

6) smoking can and does lead to bad breath, gum disease and a variety of cosmetic changes that can cause a change in one's attractiveness to a sexual partner, thus leading to erectile dysfunction

7) smoking can and does lead to a shorter life span, the ultimate in erectile dysfunction.
