Oocyte morphology does not affect fertilization rate, embryo quality and implantation rate after intracytoplasmic sperm injection.
In this study, we compared the fertilization rate and embryo quality after intracytoplasmic sperm injection (ICSI) as they relate to oocyte morphology. A total of 654 ICSI cycles yielding 5903 metaphase II oocytes were observed. The oocytes retrieved in these cycles were divided into (i) normal oocytes, (ii) oocytes with extracytoplasmic abnormalities (dark zona pellucida and large perivitellin...
متن کاملEffects of Sperm Chromatin Integrity on Fertilization Rate and Embryo Quality Following Intracytoplasmic Sperm Injection
Sperm chromatin integrity has been being recognized as an important factor in male fertility. During normal fertilization, high quality sperm with intact chromatin are selected through natural selection in journey from vagina to fallopian tube. However, using Assisted Reproductive Techniques, particularly ICSI, the natural selection is bypassed. Therefore sperm with DNA breakage have the opport...

متن کاملFertilization rate and its determinants in intracytoplasmic sperm injection
OBJECTIVE To identify predictors of fertilization rate in patients of unexplained infertility after intracytoplasmic sperm injection (ICSI). METHODS Retrospective analysis of females (282) enrolled in quasi experimental design for ICSI at "Islamabad Clinic Serving Infertile Couples" was carried out from July 2013 till June 2014. Females with unexplained infertility were included, whereas well...
متن کاملPreincubation of human oocytes may improve fertilization and embryo quality after intracytoplasmic sperm injection.
The aim of this study was to examine the relationship between different preincubation periods of oocytes and the outcome of intracytoplasmic sperm injection (ICSI). We analysed retrospectively 95 ICSI treatment cycles performed to alleviate severe male-factor infertility. Oocyte collection was performed approximately 36 h after human chorionic gonadotrophin administration. The cumulus-corona-oo...
