A number of lifestyle factors (such as smoking, alcohol abuse, etc.) are known to impact negatively overall health and wellbeing. Tobacco use is a risk factor for serious disease development. Still in the view of many scientists smoking is the easy preventable risk factor for some diseases. It is necessary to study the prevalence and influence of tobacco smoking on people who are planning to conceive a child in order to prevent the effects of damaging factors on future generations. In 2012–2013 years we questioned 255 men from infertile couples and men with proven reproductive disorders about their smoking experience, number of cigarettes smoked per day, type of cigarettes, etc. The majority of respondents were Moscow dwellers. Our survey found out that 35 % of the respondents have never smoked, 27 % quitted smoking; 38 % of the respondents smoked and 70 % of them do it regularly. The 58 % of regular smokers reported more than 10 years of smoking experience. A half of non-regular smokers have 6 or more years of smoking experience. Most of daily smokers consume more than half a pack cigarettes per day. Both regular and non-regular smokers preferred “light” and “medium” cigarettes. Among former smokers 63 % reported six or more years experience of smoking. It is typical that 54 % of quitters gave up smoking less than a year ago. The prevalence of smoking among men surveyed is more than 20 % lower than indicated for the whole country male population by most authors. We assume that it may be due to the care of men who plan to become fathers of their health and health of future children. Also long waiting time to pregnancy is likely to give rise to lifestyle habits reevaluation. On the other hand, a lot of respondents don,t give up the habit and continue to smoke more than ten cigarettes a day despite pregnancy planning.
