Retraction 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 کاملIntracytoplasmic morphologically selected sperm injection: a prospective randomized trial.
The aim of this prospective randomized study was to assess the advantages of a new modified intracytoplasmic sperm injection (ICSI) technique called intracytoplasmic morphologically selected sperm injection (IMSI) over the conventional ICSI procedure in the treatment of patients with severe oligoasthenoteratozoospermia. The new procedure consisted of IMSI based on a preliminary motile sperm org...
متن کاملIntracytoplasmic sperm injection outcome versus intracytoplasmic morphologically selected sperm injection outcome: a meta-analysis.
The development of a modified intracytoplasmic sperm injection (ICSI), called intracytoplasmic morphologically selected sperm injection (IMSI), demonstrated that a profound morphological investigation of the spermatozoon, under the magnification of 6600 x, enables outcome improvement. The aim of this study was to compare ICSI outcome with IMSI outcome. The meta-analysis results demonstrated no ...
متن کاملPregnancy rates are higher with intracytoplasmic morphologically selected sperm injection than with conventional intracytoplasmic injection.
OBJECTIVE To verify whether microinjection into retrieved oocytes of motile spermatozoa with morphologically normal nuclei, strictly defined by high power light microscopy (x >6000), improves the IVF/intracytoplasmic sperm injection (ICSI) pregnancy rate in couples with repeated ICSI failures. DESIGN Comparative prospective study testing routine IVF/ICSI outcome parameters against those of mo...
