Smoking has an effect on male fertility. It may cause erectile dysfunction, decrease sperm count, increase sperm abnormalities, and decrease sperm quality.
Smoking may lead to the development of erectile dysfunction and increase the chances of male infertility. In addition, the nicotine in cigarettes can kill sperm, which will reduce sperm count, and may inhibit hormone secretion in the male body, which will increase the chances of sperm deformities, which will have an adverse effect on the reproductive function.
In addition, regular smoking will reduce sperm density and sperm motility, which will lower sperm quality. Smoking has a greater impact on male fertility and may reduce the likelihood of pregnancy. It is recommended that men avoid smoking and secondhand smoke during pregnancy preparation.
