我们调查了科比地震（1995年1月17日）和精液质量之间的可能关系。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个月内的精子浓度超过3000万/ml，精子活力> 40%。12名男性患者来自6级地区，5名患者的房屋没有受到破坏，精子浓度和活力没有明显变化。而10例房屋部分或全部被震毁的患者，精子活力较震前显著降低（P <0.001），但精子浓度无显著性差异。在后10例患者中，有7例可以随访。在6名患者中，精子活力在地震后2至9个月恢复; 1名患者的精子活力尚未恢复，他的父亲是房屋倒塌的受害者。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可能原因。
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 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.
