The results showed that the measurement uncertainty of semen volume and progressive motility caused by inspectors was low, and their measurement results reliability was high. There were small differences in measurement results of semen volume and progressive motility among inspectors. However, the measurement uncertainty of sperm motility and abnormal sperm percentage was relatively large, and great differences were found among different inspectors. Therefore, the training of inspectors＇ measuring sperm motility and abnormal sperm percentage should be strengthened, and the comparison of measurement results among inspectors should be performed in the future.展开更多

This is discussed in light of the different purposes of semen analysis for the subfertile couple and the male patient. The two groups of progressive spermatozoa should be distinguished to help ensure that pertinent information available in the semen sample is not neglected.展开更多
目的:探讨精液处理后前向运动精子总数(post-wash total mobile sperm count,PTMC)对单纯以少、弱精子症为病因引起不孕不育症患者的夫精宫腔内人工授精(intrauterine insemination,IUI)妊娠率的影响。方法:分析2015年3月至2016年3月单...目的:探讨精液处理后前向运动精子总数(post-wash total mobile sperm count,PTMC)对单纯以少、弱精子症为病因引起不孕不育症患者的夫精宫腔内人工授精(intrauterine insemination,IUI)妊娠率的影响。方法:分析2015年3月至2016年3月单纯以少、弱精子症为适应症接受IUI治疗的125个周期的临床资料,按处理后前向运动精子数进行分组,A组19个周期:<10×10~6、B组71个周期:10×10~6~20×10~6、C组35个周期:>20×10~6,比较各组临床妊娠率。结果:周期总临床妊娠率15.20%,A组周期妊娠率10.53%,B组周期妊娠率16.90%,C组周期妊娠率14.29%,各组妊娠率比较差异无统计学意义(P>0.05)。结论:(1)由少、弱精子症引起不育的患者行IUI治疗,即使PTMC<10×10~6也能获得一定的妊娠率。(2)精液处理后前向运动精子数对IUI的妊娠率有一定影响,但妊娠率并非一定随着PTMC的增多而提高。展开更多
