To evaluate the effects of sperm with different parameters and sources on the outcomes of intracytoplasmic sperm injection
(ICSI), 1972 ICSI cycles were analyzed retrospectively. Groups 1 to 5 were composed of cycles using ejaculated sperm and were
grouped according to sperm quantity, quality, and morphology into normal (288 cycles), or mild (329 cycles), moderate (522
cycles), severe (332 cycles), and extremely severe (171 cycles) oligozoospermia and/or asthenozoospermia and/or teratozoospermia
(OAT) groups. Group 6 was composed of 250 cycles using testicular or epididymal sperm, and Group 7 consisted of 80 cycles
using frozen-thawed sperm. We found that fertilization rates were gradually reduced from Groups 1 to 6, and reached statistical
difference in Groups 5 and 6 (P<0.05). The high-quality embryo rate was higher in Group 1 than in Groups 2, 3, 5, 6, and 7 (P<0.05). No statistical differences were observed in the rates of embryo cleavage, clinical pregnancy, miscarriage, live-birth,
premature birth, low birth weight, weeks of premature birth, average birth weight, or sex ratio for all seven groups (P>0.05). A total of nine cases of malformation were observed, with a malformation rate of 1.25% (9/719). In conclusion, different
sperm sources and parameters can affect ICSI outcomes before embryo implantation. A full assessment of offspring malformation
will require further study using a larger sample size. 相似文献

本文应用精子功能分析和常规精液检查,对20例正常生育男性和34例白细胞精子症患者进行了综合精液质量评定。结果发现:精子功能分析和常规精液检查中顶体完率、g型精子率、正常形态及精子活力参数在二组间具有显著差异。而在有无临床慢性生殖道炎症表现的白细胞精子症组间则差异不明显实结果表明:正常生育男性之精液质量明显优于白细胞精子症者;而后者与是否有临床生殖道现无关。 相似文献
