According to the results of the special laboratory test revealing the ability of the sperm cell to fertilize the egg cell the sperm of two thirds of chronic smokers is unable to perform this task. The average fertilizing capacity of smoking males was 75% lower than in those who don’t smoke at all. 

Loni Burkman the main research author explains: “Sperm cells have their own receptors to nicotine as other cells of the body. They reveal it and react it correspondingly. This occurs as tobacco nicotine is quite similar to the most important neurochemical substance that is being synthesized in the body”.

Scientists affected the non-smoking males’ sperm with the nicotine and thus revealed that this material may affect three sperm cell functions that are quite required on the fertilization process. "Nobody of the smokers took part in the research has its sperm quite unable to fertilization. However the sperm cells potential of the smoker is only 25% of the non-smoker’s potential” says Burkman.

The fertilization capacity of the sperm cells was depended up to the number of the cigarettes per day and the length of the smoking at whole. Smoking males as well as females should always remember that the nicotine may harm DNA that your child will inherit.
