目的调查嘉兴婚检男性精液质量状况,分析不良生活习惯因素对精液质量的影响。方法收集2011年5月-2014年5月在嘉兴市婚检医疗机构自愿进行婚检的536份20~50岁成年男性精液样本,检测精液量、精子密度(sperm concentration,SC)、精子存活率(sperm survival percentage,SSP)、前行精子百分率(sperm forward movement percentage,SFMP),正常形态精子百分率(normal morphological sperm percentage,NMSP)等指标,根据WHO精液健康标准进行评价,并对受检对象进行问卷调查。结果根据WHO精液健康标准,样本精液总合格率为51.5%,随着年龄的增加,精液总合格率显著降低(χ2=21.413,P=0.001);2011-2013年组间总合格率差异无统计学意义(P>0.05)。Logistic回归分析显示抽烟(OR=0.587,95%CI=0.381~0.842)、饮酒(OR=0.462,95%CI=0.249~0.791)、射精频率(OR=1.413,95%CI=1.187~1.686)进入回归方程,是独立的影响因素。结论嘉兴市婚检男性精液质量合格率不高,20~30岁精液质量最高,吸烟、饮酒、射精频繁过高可能会导致精液质量降低。
Objective To investigate the quality of male semen in Jiaxing premarital examination and analyze the influence of bad habits on semen quality. Methods A total of 536 adult male semen from 20 to 50 years old were collected from May 2011 to May 2014 in a premarital medical examination institution in Jiaxing City. The sperm concentration (SC), sperm survival (sperm) Survival percentage (SSP), sperm forward movement percentage (SFMP), normal morphological sperm percentage (NMSP) and other indicators were evaluated according to WHO sperm health standards, and the subjects were surveyed . Results According to the WHO sperm health standards, the total qualified rate of sperm was 51.5%. With the increase of age, the total eligible rate of sperm was significantly lower (χ2 = 21.413, P = 0.001). There was no statistical difference in the total eligible rates between groups in 2011-2013 Significance (P> 0.05). Logistic regression analysis showed that smoking (OR = 0.587, 95% CI = 0.381-0.842), drinking (OR = 0.462, 95% CI = 0.249-0.791) and ejaculation frequency (OR = 1.413, 95% CI = 1.187-1.668) Regression equation is an independent factor. Conclusion The passing rate of male semen in Jiaxing city is not high, the quality of semen is the highest in 20 ~ 30 years old, smoking, drinking, frequent ejaculation may result in the decrease of semen quality.
