A number of studies show that smoking is related to the difficulty getting and maintaining an erection.
Many toxins present in cigarettes especially carbon monoxide, can damage the circulatory system, which hinders the flow of blood in the penis which is necessary for erection.
In addition, smoking is one of the major causes of Erectile Dysfunction.
A study published in the Journal of Urology in 2000 found out that 68% of men with high blood pressure aged 40-79 experienced erectile dysfunction. At least 45% of these cases were considered severe sexual ailments.
High blood pressure in men may lead to low testosterone levels, which is a male hormone that plays a crucial role in the sexual arousal. Low testosterone levels lead to decreased arousal and sexual performance.
Toxins found in cigarettes may also harm the testes. Smoking may affect the semen and the sperm, reducing their mobility and quality. Men who smoke tend to have lower sperm counts and malformed sperms than their non-smoking counterparts.
