【Abstract】 Objective: To determine the effects of smoking, alcohol, coffee and tea drinking on the semen quality in normal Chinese young men undergoing premarital examination. Methods:From Dec. 1998 to Dec.1999, we recruited 562 male volunteers accepting premarital examination in seven provinces/cities’ MCH centers (aged 22～30) and analyzed their semen parameters (obtained by masturbation). Results: Logistic multiple analyses showed smoking could decrease semen volume and total sperm count; alcohol drinking only might influenced semen volume. There was no relationship between tea drinking and semen quality; coffee drinking could be harmful to sperm forward progression. Conclusions: Male lifestyle such as smoking, and coffee drinking could be harmful to semen quality; alcohol, tea drinking might have no negative effects on semen quality.更多还原
