高阴囊温度是不育患者的常见发现，实验研究表明，特定类型的热暴露会降低精液质量。越来越多的男性采用久坐不动的工作姿势，这会增加阴囊温度。对99例健康男性的精液和血液样本进行了24小时连续监测协议获得的阴囊皮肤温度相关分析。在工作和业余时间的久坐姿势的信息收集问卷调查。阴囊温度升高与精子排出量呈负相关。白天阴囊平均温度每升高1 ℃，精子浓度降低40%（95%CI：8- 71%）。总精子计数、FSH和精子结合素B的结果相似。运动性、形态、pH和睾酮与温度无显著相关性。久坐姿势和精液质量之间只有微弱和不一致的联系。我们的结论是阴囊温度和精液质量密切相关。在普通工作中遇到的久坐不动的工作姿势，虽然是阴囊温度的一个强有力的决定因素，但似乎对精液质量没有任何影响。(C)2002年爱思唯尔科技有限公司All rights reserved.
A high scrotal temperature is a common finding in infertile patients and experimental studies indicate that specific types of heat exposure reduce semen quality. More and more men have a sedentary work position, which increases scrotal temperature. Semen and blood samples from 99 healthy men were analysed in relation to scrotal skin temperature obtained by a 24-h continuous monitoring protocol. Information on sedentary position at work and during spare time was collected by questionnaires. A negative correlation was found between high scrotal temperature and sperm output. Sperm concentration decreased 40% per 1 degreesC increment of median daytime scrotal temperature (95 % CI: 8-71 %). Similar results were found for total sperm count, FSH, and inhibin B. Motility, morphology, pH, and testosterone were not significantly associated with temperature. Only weak and inconsistent associations were found between sedentary position and semen quality. We conclude that scrotal temperature and semen quality are closely associated. Sedentary work position encountered in ordinary jobs, although a strong determinant of scrotal temperature, does not seem to have any effect on semen quality. (C) 2002 Elsevier Science Inc.
