A retrospective study was carried out which focused on the impact of lifestyle and exposure to different external factors on sperm quality. A questionnaire was sent to 312 men who had previously attended our laboratory for semen analysis. Their answers were correlated to sperm quality. Men exposed to a relatively high degree of X-rays were found to have significantly reduced sperm count. A previous symptomatic genital infection did not significantly influence the sperm quality, but an earlier sexually transmitted disease in the female partner was associated with a reduced rate of pregnancy. Frequency of ejaculation was significantly positively correlated to sperm motility and inversely related to both semen volume and proportion of sperm with abnormal morphology. Information on exposure to the remaining factors was not related to reduced sperm quality or fertility.
开展了一项回顾性研究，重点关注生活方式和接触不同外部因素对精子质量的影响。向312名曾到我们实验室进行精液分析的男性发送了一份问卷。他们的回答与精子质量相关。发现接触相对高剂量X射线的男性精子数量显著减少。既往有症状的生殖器感染对精子质量没有显著影响，但女性伴侣早期的性传播疾病与妊娠率降低有关。射精频率与精子活力显著正相关，与精液量和形态异常精子比例呈负相关。关于接触其他因素的信息与精子质量下降或生育力降低无关。
