摘要
目的 分析精子因素对反复自然流产的影响.方法 病例组:21例不明原因反复自然流产患者丈夫,对照组:20名已生育男子,采用精子染色质结构分析方法 分析精子DNA完整性,参照WHO标准分析精液质量,选用X、Y和18号染色体探针进行荧光原位杂交(FISH)检测精子的非整倍体性.结果 病例组正常形态率(10.8±2.8)%低于对照组,DNA碎片指数(DNA fragmentation index,DFI)值(21.7±6.7)%、18染色体非整倍体率(0.23±0.09)%、性染色体非整倍体率(0.80±0.14)%均明显高于对照组,差异均具有统计学意义(P＜0.01).结论 精子形态、DNA完整性和染色体非整倍体率是反复自然流产的相关性因素.
Objective To analyze the effect of sperm factor on recurrent pregnancy lass.Methods Accordingto WHO criteria,we routinely analyzed the sperm of 21 unexplained recurrent pregnancy loss patients as study group.and 20 proven fertility men as control group.Meanwhile,we evaluated sperm chromosome aneuploidy for chromosomes 18,X and Y using standard FISH procedure,and sperm DNA ingegrity using sperm chromatin structure assay(SCSA)procedure.Results The percentage of normal morphology sperm is(10.8±2.8)%,and DFI value is(21.7±6.7)%,and the percentage of sperm aneuploidy for sex chromosome and chromosome 18 is(0.80±0.14)%and(0.23 ±0.09)%respectivelyin study group.The differences between the two groups were statistically significant(P＜0.01).Conclusion Sperm morphology,DNA integrity and chromosome aneuploidy are the correlative factors to recurrent pregnancy loss.
