How does smoking affect male fertility?

Cigarettes contain toxins that are often blamed for their bad effect on male health. Men who smoke are exposed to high levels of metals like cadmium and lead, which have been linked to decreased fertility. 

Lead and cadmium levels have been found to significantly affect semen quality resulting in poor sperm concentration, shape, and movement. 

However, you must know that smoking does not stand to be the only cause of infertility in men. There can also be other causes of infertility like age, low sperm production or abnormal sperm function. 

However, smoking does aggravate the complications by pushing the patients suffering from infertility over the edge into infertility.

Here are some common problems that may arise when you don’t quit smoking:

  • Sperm morphology

It refers to the sperm’s shape. Studies suggest that males who smoke tend to have less healthy-shaped sperm as compared to men who don’t. 

Smoking can change the shape of the sperm, due to which the sperm fails to swim properly enough to reach the egg. And even if this abnormally shaped sperm reaches the egg, by then, it has lost the power to fertilize the egg.

  • Sperm motility

The toxins in smoke negatively affect sperm motility. These toxins decrease the concentration of sperms in the semen and can affect the overall quality of sperms.

  • Sperm DNA

Men who smoke have sperm with greater DNA fragmentation. This leads to problems with fertilization, embryo development, increased miscarriage rates, and embryo implantation.

  • Sperm concentration

Sperm concentration refers to the number of sperm present in semen. As per studies, men who smoke tend to have a 23 percent reduction in sperm concentration as compared to men who don’t smoke. 

In addition, smoking hinders the functionality of the reproductive system’s blood vessels, which causes erectile dysfunction in male smokers. 

Smoking also adversely affects male fertility by:

  • Damaging sperms genetically

  • Imbalancing hormones
