Micro-rubbing sperm immobilization promotes fertilization and oocyte utilization in intracytoplasmic sperm injection.

ABSTRACT:

Background

Sperm immobilization is an important step in intracytoplasmic sperm injection (ICSI) as it is necessary for oocyte activation by the spermatozoa. Several techniques are available for sperm immobilization. However, the effects of sperm mobilization techniques on intracytoplasmic sperm injection outcomes have not been established as most of the reports of studies on sperm immobilization techniques are inconsistent. This study aimed to evaluate a mild aggressive mechanical sperm immobilization technique: micro-rubbing, and investigate the effectiveness of micro-rubbing sperm immobilization in ICSI.

Methods

Matched retrospective cohort study of patients who underwent intracytoplasmic sperm injection between April 2018 and June 2023 were enrolled. Non-preimplantation p
