The shape of the sperm midpiece in intracytoplasmic morphologically selected sperm injection relates sperm centrosomal function

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...

Comparison between intracytoplasmic sperm injection and intracytoplasmic morphologically selected sperm injection in oligo-astheno-teratozoospermia patients

OBJECTIVE The aim of this study was to evaluate the efficiency of the intracytoplasmic morphologically selected sperm injection (IMSI) technique compared with conventional ICSI and previous ICSI attempts in oligo-astheno-teratozoospermia (OAT) patients. METHODS The sperms were selected under high magnification (6,600×) and used to induce fertilization in previous ICSI patients by IMSI. These ...

Intracytoplasmic 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 ...

Intracytoplasmic 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 ...
