[Effect of exogenous toxins on fertility].

The influence of certain harmful noxae on male fertility was investigated statistically in a large group of andrological patients. A significant correlation was found to exist between alcohol consumption and potency disorders. Patients admitting to a high level of drinking also indicated greater stress at work, and an elevated use of drugs, while more tended to use the sauna. In the case of nicotine a significant influence on sperm morphology and sperm count was shown.
