Abstract

When sperm motility from vibratory or electroejaculates of spinal cord injured men reveals consistently poor motility (< 10%), one should consider accessory gland factors as a potential cause. Herein, we report the case of a 22 year old paraplegic male who consistently had motility of 1-2% on electroejaculates. He was evaluated in the office with vas deferens sperm retrieval, which revealed a 0.4 ml volume, 9 million/ml density, and 67% motility. We suggest that this significant percent motility differential can only be explained by an accessory gland factor impacting negatively upon this individual's fertility. We propose vas deferens sperm retrieval as a potentially diagnostic and therapeutic procedure in similar cases.

摘要

当脊髓损伤男性通过振动射精或电射精获得的精子活力持续较差（<10%）时，应考虑附属腺因素作为潜在原因。在此，我们报告一例22岁截瘫男性病例，其电射精后的精子活力持续为1%-2%。在门诊对其进行了输精管精子采集评估，结果显示精液量为0.4毫升，密度为900万/毫升，活力为67%。我们认为，这种显著的活力差异百分比只能通过附属腺因素对该个体生育能力产生负面影响来解释。我们建议，在类似病例中，输精管精子采集可作为一种潜在的诊断和治疗方法。
