Comparison of Embryo Development between Intracytoplasmic and Piezo-Assisted Sperm Injection after Treating Mouse Sperms by Ca2+ Ionophore
The purpose of this study was to evaluate the efficiency of intracytoplasmic sperm injection (ICSI) and Piezo-assisted sperm injection after pretreatment with calcium ionophore (CaI) on the mouse embryo development. Methods: In this study, the conventional ICSI and Piezo-ICSI procedures were used. The efficacy of the methods was examined after mouse matured oocytes were fertilized with or witho...
متن کاملRetraction Note: Intracytoplasmic morphologically selected sperm injection versus conventional intracytoplasmic sperm injection: a randomized controlled trial
Retraction The Editors-in-Chief are retracting this article [1] because the study was not conducted with the appropriate ethical oversight. Contrary to the statement in the article that ethics committee approval was not required, an investigation by the Arcispedale Santa Maria NuovaIRCCS has determined that the study should have been reviewed and approved by an ethics committee. All authors agr...
متن کاملIntracytoplasmic morphologically selected sperm injection versus conventional intracytoplasmic sperm injection: a randomized controlled trial
BACKGROUND Intracytoplasmic morphologically selected sperm injection (IMSI) is still proposed and employed in the clinical practice to improve the reproductive outcome in infertile couples scheduled for conventional intracytoplasmic sperm injection (cICSI). The aim of the current randomized controlled trial (RCT) was to test the hypothesis that IMSI gives a better live birth delivery rate than ...
متن کاملUltrastructure of gametes after intracytoplasmic sperm injection.
The ultrastructure of 18 metaphase-II oocytes after intracytoplasmic sperm injection (ICSI) was analysed from 30 min to 8 h following the microinjection. Three control metaphase-II oocytes were not injected. The 21 oocytes were embedded individually and examined in serial pole-to-pole sections. Seventeen oocytes had been matured in vitro from the germinal vesicle stage and showed ultrastructura...
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...
