Welcome to HealthcareMagic forum.
Nicotine is associated with erectile dysfunction
. This is mainly attributed to changes in the peripheral blood vessels. That being said, I would not relate the problem to just nicotine patches but combination of smoking and nicotine. In addition other medical problems such as diabetes
, high blood pressure
and psychological stressors need to be considered as a cause.
All these parameters can be checked under the guidance of a competent urologist
Hope this answers your query.
