A model for differentiating live and dead sperm cells during intracytoplasmic sperm injection (ICSI) is proposed.
We used pentoxifylline, a phosphodiesterase inhibitor known to enhance sperm motility, to initiate motility in testicular spermatozoa. Ten immotile testicular sperm samples were divided into two parts for examination of sperm motility with and without pentoxifylline treatment at 30, 60, and 90 min.
The samples without pentoxifylline remained immotile even after 90 min of incubation: the addition of pentoxifylline initiated sperm motility in all samples: 51.8 +/- 10.2, 64.4 +/- 9.4, and 70.8 +/- 8.9% (mean +/- SD) at 30, 60, and 90 min, respectively.
That pentoxifylline may be used to differentiate live testicular spermatozoa during ICSI, which may improve fertilization and pregnancy rates, is suggested.
提出一种在卵胞浆内单精子注射(ICSI)过程中区分活精子细胞和死精子细胞的模型。
我们使用己酮可可碱,一种已知可增强精子活力的磷酸二酯酶抑制剂,来启动睾丸精子的活力。将10个无活力的睾丸精子样本分成两部分,分别在30、60和90分钟时检测有无己酮可可碱处理情况下的精子活力。
未用己酮可可碱处理的样本即使孵育90分钟后仍无活力;添加己酮可可碱后所有样本均出现精子活力:在30、60和90分钟时分别为51.8±10.2%、64.4±9.4%和70.8±8.9%(平均值±标准差)。
提示己酮可可碱可用于在ICSI过程中区分活的睾丸精子,这可能提高受精率和妊娠率。
