Abstract

BACKGROUND

In this study we examined whether stress has a negative influence on sperm quality. To investigate this issue we developed a scale assessing perceived stress resulting from infertility.

METHODS AND RESULTS

The Infertility Distress Scale was constructed based on the data of 158 infertility patients contacting an andrological clinic for the first time. The Infertility Distress Scale consists of items assessing self-reported stress, different appraisals of infertility and cognitive involvement in infertility. The scale was shown to have good psychometric properties. Changes in sperm quality were predicted by this scale for 69 patients. Changes in sperm concentration and sperm motility were predicted correctly 75.4 and 65.6% of the time, respectively. While these prediction accuracies were significantly better than chance prediction, the Infertility Distress Scale had no predictive value for changes in morphology.

CONCLUSION

Results indicate that distress caused by infertility is a risk factor for a decrease in sperm quality.

摘要

背景

在本研究中，我们探讨了压力是否会对精子质量产生负面影响。为了研究这个问题，我们编制了一个量表来评估因不孕不育而感受到的压力。

方法与结果

不孕不育困扰量表是根据158名首次前往男科诊所就诊的不孕不育患者的数据编制而成。不孕不育困扰量表包含评估自我报告压力、对不孕不育的不同认知以及对不孕不育的认知参与度的项目。该量表显示出良好的心理测量特性。该量表对69名患者的精子质量变化进行了预测。精子浓度和精子活力变化的预测准确率分别为75.4%和65.6%。虽然这些预测准确率明显高于随机预测，但不孕不育困扰量表对精子形态变化没有预测价值。
