    Cigarette smoking significantly increases sperm morphological abnormalities in men attending infertility clinics. This suggests smoke exposure may cause genetic damage to sperm cells, impacting male fertility.

    Area of Science:

    • Reproductive biology
    • Toxicology
    • Genetics

    Background:

    • Male infertility is a significant health concern.
    • Cigarette smoking is a widespread behavior with known health risks.
    • Previous research indicates smoking affects blood cell genetics.

    Purpose of the Study:

    • To investigate the association between cigarette smoking and sperm morphological abnormalities.
    • To explore potential genetic damage in sperm cells of smokers.

    Main Methods:

    • Sperm samples were collected from 43 male cigarette smokers and 43 non-smokers.
    • Morphological abnormalities in sperm were assessed.
    • Participants were attending an infertility clinic.

    • Smokers exhibited a significantly higher percentage of abnormal sperm forms compared to non-smokers.
    • The observed sperm abnormalities suggest a potential link to smoking-induced damage.

    Conclusions:

    • Cigarette smoking is linked to increased sperm morphological abnormalities.
    • These abnormalities may indicate genetic damage to sperm cells due to smoke product exposure.
    • Smoking may negatively impact male reproductive health and fertility.
