Objectives
Narrative objectives1
The target patients will be randomly divided into a study group (If the oolemma extension is low when the pipette is punctured during ICSI, re-puncture from a different site) and a control group (Do not re-puncture) to compare the oocyte degeneration rate after ICSI and to clarify the therapeutic effect of re-puncture.
