Effect of smoking on fertility of men

We all know that cigarette smoking is injurious to health. About half of all smokers who keep smoking will die because of the habit. Statistics show that smoking cigarettes kills more people than alcohol, accidents, suicide, AIDS, homicide, and illegal drugs combined. Apart from these detrimental effects smoking can also affect fertility of men and women. The harmful effects of smoking on male fertility are given below.

Effect of smoking on semen

Smoking affects quality and quantity of semen.
The concentration of nicotine builds up in semen and affects normal function of sperms.
The volume of semen is low in smokers compared to non smokers.
The concentration of spermatozoa or sperms decreases in smokers. It is 23% less than that of non smokers. Thus low sperm count causes infertility in men.
Smoking reduces sperm motility. The motility or movement of sperm is very essential for fertilization. Reduced sperm motility can cause male infertility.
Smoking increases number of abnormal sperms. Abnormal sperms can cause abortion or other birth defects.
Seminiferous tubules are tubular structures in which spermatozoa or sperms develop. Smoking cigarettes can damage these tubules hindering the development of sperms.

Effect of smoking on male hormones

Smoking can reduce male hormone or testosterone. Even the growth hormone is affected in smokers. Reduced testosterone levels can cause low libido or low sexual drive.

Effect of smoking on sexual function

Nicotine in cigarettes, although regarded by smokers as a stimulant, only worsens the harmful effects of carbon monoxide by increasing heart rate and elevated blood pressure. There is a strong link between high blood pressure and Erectile Dysfunction.

Scientists have found that smoking leads to fat deposition in blood vessels. This reduces the inner circumference of blood vessels. Even elasticity of blood vessels diminishes as a result of sustained smoking. Thus arteries fail to supply adequate amount of blood to organs of body and male reproductive system is no exception to this inadequacy. This paves way for Erectile Dysfunction.

When a person smokes he inhales large amounts of carbon monoxide. Carbon monoxide deprives the voluntary muscles as well as vital organs such as brain, heart etc of oxygen. When these vital organs do not receive sufficient oxygen, they immediately lose their ability function efficiently and optimally. Principally, the heart has to work much harder to deliver oxygenated blood to all parts of the body. Naturally, this leads takes a toll on the supply of blood to the male genital organ as well. As full erection needs effective and optimum supply of blood, any inadequacy in blood supply leads to Erectile Dysfunction.
