Abstract

BACKGROUND

The question of whether patients are more likely to succeed with testicular sperm intracytoplasmic sperm injection (T-ICSI) after unsuccessful ICSI with ejaculated sperm (Ej-ICSI) remains unknown.

OBJECTIVE

The study aimed to identify potential predictors of successful T-ICSI in men with idiopathic infertility and oligozoospermia (sperm concentration < 15 × 10/mL, non-azoospermic) who had previously experienced unsuccessful Ej-ICSI.

MATERIALS AND METHODS

In total, 154 couples with male partners who had oligozoospermic conditions after two unsuccessful cycles of Ej-ICSI switched to T-ICSI. Before initiating T-ICSI, the sperm DNA fragmentation index (DFI) was assessed in ejaculated specimens. Participants were divided into two groups: group A (live birth (+), n = 60) and group B (live birth (-), n = 94).

RESULTS

Fertilization, clinical pregnancy, live births, and miscarriages had rates of 72.7%, 44.2%, 39%, and 5.2%, respectively. The total motile sperm (TMS) count in group A was significantly higher (3.8 ± 1.5 million) than in group B (3 ± 1.6 million; p = 0.002). DFI was significantly higher in group A (24.2 ± 12.3) than in group B (18.1 ± 11; p = 0.001). Hormone levels and oocyte counts showed no statistically significant differences between groups. Multivariate regression analysis revealed that TMS (odds ratio [OR]: 1.46; 95% CI, 1.14-1.87, p = 0.003) and DFI (OR: 1.04; 95% CI, 1.01-1.08, p = 0.009) were found to be significant predictors of live birth outcomes. At a cutoff point of 2.55 (area under the curve [AUC] = 0.65), the optimal sensitivity and specificity values for TMS were 78% and 48%, respectively. At a cutoff point of 25.8 (AUC = 0.65), DFI had a maximum sensitivity of 51.7% and a specificity of 78.7%.

CONCLUSIONS

TMS and DFI were found to be significant predictors of live birth outcomes in couples with oligozoospermic male partners undergoing T-ICSI. These findings may help clinicians tailor treatment strategies for this specific patient population.
