Abstract

Many studies reveal the presence of an effect of age, abstinence and seasons on semen parameters, but the number of patients enrolled is small and the presence of therapies unknown. We aimed to evaluate the correlation between abstinence days, age, season, and semen parameters (volume, concentration, progressive motility, total number of sperms, morphology) among men referred to our laboratory. We proceeded with a cross-sectional, observational, exploratory study in an Andrology laboratory. A population of 348 male partners of infertile couples who did not receive any treatment in the 3 months preceding semen analysis was selected. Sperm volume, concentration, total number, progressive motility and morphology of sperms were conducted strictly following the guidelines indicated in the last edition of WHO manual for semen analysis. Pearson's correlation analysis and Kendall's correlation analysis were applied. Sperm concentration, semen volume and sperm total number moderately increased as well as the abstinence, while progressive motility and morphology moderately decreased. Regarding the age, in the 20-35 age group there was a weak inverse association with concentration, total number, motility and morphology and a weak positive association with volume; in the 42-63 age group there was a moderate positive association between age and concentration, motility and morphology, but an inverse association with volume. No correlation emerged between seasonal variations and semen parameters. These results suggested the importance of correct information to patients for proper semen analysis for diagnostic and therapeutic purposes.

不育夫妇未治疗男性伴侣的年龄、禁欲、季节与精液参数的相关性分析。
许多研究揭示了年龄、禁欲和季节对精液参数的影响,但纳入的患者数量很少,治疗方法也未知。我们的目的是评估到我们实验室的男性禁欲天数、年龄、季节和精液参数(体积、浓度、进行性运动、精子总数、形态)之间的相关性。我们在男科实验室进行了横断面、观察性、探索性的研究。选取348名在精液分析前3个月内未接受任何治疗的不育夫妇的男性伴侣。精子的体积、浓度、总数、进行性运动和形态均严格按照世卫组织上一版精液分析手册的指导方针进行。采用Pearson相关分析和Kendall相关分析。精子浓度、精液量和精子总数适度增加,禁欲适度增加,进行性运动和形态适度减少。年龄方面,20 ~ 35岁年龄组与浓度、总数、运动性、形态呈弱负相关,与体积呈弱正相关;在42-63岁年龄组中,年龄与浓度、运动性和形态呈正相关,而与体积呈负相关。季节变化与精液参数之间没有相关性。这些结果提示了正确的信息对患者进行正确的精液分析对诊断和治疗的重要性。
