Effects 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 کاملIn vitro fertilization by intracytoplasmic sperm injection.
Intracytoplasmic sperm injection (ICSI) is the latest, and by far the most efficient, variant of micromanipulation-assisted fertilization, whereby a single spermatozoon is selected, aspirated into a microinjection needle and injected to the oocyte cytoplasm. The development of this technique is mainly linked to application in human assisted reproduction for which it enables fertilization with d...
متن کاملFailed fertilization after clinical intracytoplasmic sperm injection.
Intracytoplasmic sperm injection (ICSI) has resulted in pregnancy and birth for many couples, including those with severe male factor infertility. However, even after ICSI, complete failure of fertilization occurs in 1-3% of cycles. Most cases occur due to low number of mature oocytes, failure of oocyte activation or non-availability of appropriate spermatozoa for injection. Given the significa...
