[Effects of cigarette, alcohol consumption and sauna on sperm morphology].

Objective: To investigate effects of cigarette, alcohol consumption and sauna on sperm morphology. Methods: 602 cases of male infertility were selected from our case database, who were divided into three subgroups: smoking(243), drinking(224), sauna(135) and those without any of the above habbits were taken as the corresponding controls. The sperm morphology were analyzed by automated sperm morphology analyzer(ASMA). A questionnaire was voluntarily filled out by patients in order to investigate cigarette, alcohol consumption and sauna frequency. Results: The normal morphologic sperm rates in cigarette, alcohol consumption and sauna groups were lower than those in the corresponding control groups, respectively(P 0.05, P 0.001). Percentages of irregularity head sperm were higher than those in normal controls, respectively(P 0.05). Conclusion: Cigarette, alcohol consumption and sauna could affect sperm morphology, especially caused increasing of irregularity head sperm.
