Failed 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...
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 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/intracytoplasmic sperm injection for male infertility
Progress in the field of assisted reproduction, and particularly micromanipulation, now heralds a new era in the management of severe male factor infertility, not amenable to medical or surgical correction. By overcoming natural barriers to conception, in vitro fertilization and embryo transfer (IVF-ET), subzonal sperm insemination, partial zona dissection, and intracytoplasmatic injection of s...
متن کاملLow-Dose Urinary Human Chorionic Gonadotropin is Effective for Oocyte Maturation in In Vitro Fertilization/ Intracytoplasmic Sperm Injection Cycles Independent of Body Mass Index
Objective Currently, there is no agreement on the optimal urinary derived human chorionic gonadotropin (u-hCG) dose requirement for initiating final oocyte maturation prior to oocyte collection in in vitro fertilization (IVF), but doses that range from 2500- 15000 IU have been used. We intended to determine whether low dose u-hCG was effective for oocyte maturation in IVF/intracytoplasmic sperm...
