Smoking & Alcohol
*Only 12% alcoholics and six per cent smokers showed normozoospermia compared to 37 % nonalcoholic nonsmoker males.
*Teratozoospermia, followed by oligozoospermia dominated alcoholics.
*Overall impact of asthenozoospermia and teratozoospermia, but not of oligozoospermia, was observed in smokers.
*Alcohol abuse targets sperm morphology and sperm production.
*Smoke-induced toxins primarily hamper sperm motility and seminal fluid quality.
*Progressive deterioration in semen quality is related to increasing quantity of alcohol intake and cigarettes smoked.
