Intracytoplasmic morphologically selected sperm injection: a prospective randomized trial

Intracytoplasmic 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...

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...

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 ...

Gender incidence of intracytoplasmic morphologically selected sperm injection-derived embryos: a prospective randomized study.

The aim of this prospective randomized study was to determine if the use of intracytoplasmic morphologically selected sperm injection (IMSI) is associated with gender incidence. Couples who underwent IVF-preimplantation genetic screening (PGS) cycles, as a result of advanced maternal age, were randomly allocated into two groups: intracytoplasmic sperm injection (ICSI; n=80) or intracytoplasmic ...
