To demonstrate whether the ICSI POSITION DETECTOR (IPD) by image analysis, which can identify the oolemma where rupture is likely to occur, is clinically useful for reducing unintentional membrane rupture (UMR) and oocyte degeneration.

One of the problems during intracytoplasmic sperm injection (ICSI) procedure is unintentional membrane rupture (UMR) which often predisposes to subsequent oocyte degeneration. We reported that the oolemma has specific shape patterns by image analysis using Local Binary Pattern (LBP) that can determine the location where rupture is likely or unlikely to occur. Using LBP, we have developed the ICSI Position Detector (IPD). The aim of this study was to demonstrate whether the IPD is useful to identify the optimal puncture location to prevent UMR on ICSI procedure.
ICSI was performed not using the IPD.

The rates of UMR (7.0% vs. 12.9%, P = 0.004) and degeneration (2.4% vs. 6.1%, P<0.01 = 0.008) were significantly lower in the IPD group than in the non-IPD group. However, no significant differences were observed in the rates of fertilization (2PN, 83.8% vs. 78.9%), blastocyst formation (48.5% vs. 48.8%), or good-quality blastocysts (22.5% vs. 20.5%).

Between January 2020 and October 2022, this study included 917 oocytes inseminated with Piezo ICSI from 113 consenting infertile patients with two or more mature oocytes retrieved, and moving images were recorded during Piezo-ICSI using IPD.
In the sibling study, oocytes (n=917) were randomly divided into two groups with or without IPD. If the number of mature oocytes recovered was uneven, they were allocated according to whether the patient unique ID number was even or odd. The remaining oocyte was allocated to the IPD group when the patient ID was even, in the case of an odd number, it was allocated to the non-IPD group.
In the IPD group, IPD was applied to 458 mature oocytes and Piezo-ICSI was performed at a position identified by IPD as having a low risk of UMR (IPD group). The remaining 459 oocytes were inseminated by Piezo-ICSI without IPD (non-IPD group). Piezo-ICSI with IPD was performed first, followed by the procedure without IPD.
Culture results with or without IPD were compared in terms of the rates of UMR, degeneration, fertilization, blastocyst formation, and good-quality blastocysts.
