We investigated a possible relationship between the Kobe earthquake (January 17, 1995) and the quality of semen. We assessed sperm concentration and motility of 27 male patients who had a concentration of more than 30 million/ml and >40% sperm motility within 5 months before the earthquake. Twelve male patients from districts with a magnitude of <4 on the Richter scale showed no difference in sperm concentration and motility before and after the earthquake. Of 15 male patients from districts with a magnitude of >6, five patients whose houses received no damage showed no distinct changes in sperm concentration and motility. In contrast, 10 patients whose houses were partially or completely destroyed showed significantly (P < 0.001) lower sperm motility after the earthquake than before, although no significant difference of sperm concentration could be observed. Of these latter 10 patients, seven could be followed. In six patients, sperm motility was restored between 2 and 9 months after the earthquake; the sperm motility in one patient, whose father died a victim of the house crash, has not yet recovered. Thus, the acute stress resulting from such a catastrophic earthquake could be a possible cause of reduced sperm motility.
我们调查了1995年1月17日神户地震与精液质量之间可能存在的关系。我们评估了27名男性患者的精子浓度和活力，这些患者在地震前5个月内精子浓度超过3000万/毫升且精子活力>40%。来自里氏震级<4级地区的12名男性患者在地震前后精子浓度和活力没有差异。在15名来自震级>6级地区的男性患者中，5名房屋未受损的患者精子浓度和活力没有明显变化。相比之下，10名房屋部分或完全被毁的患者在地震后精子活力显著低于地震前（P<0.001），尽管未观察到精子浓度有显著差异。在这10名患者中，7名患者可进行随访。6名患者在地震后2至9个月精子活力恢复；1名患者的父亲在房屋倒塌中遇难，其精子活力尚未恢复。因此，这种灾难性地震造成的急性应激可能是精子活力降低的一个原因。
