Abstract:
Objective:To explore the relationship between sperm DNA integrity, semen parameters, seminal plasma neutral α-glucosidase activity and in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes. Methods:The clinical data of 300 male infertile patients who underwent routine semen analysis in the Second Affiliated Hospital of Air Force Medical University from October 2023 to April 2024 and whose spouses received IVF/ICSI treatment were retrospectively analyzed. The results of sperm DNA integrity [sperm DNA fragmentation index (DFI)], semen parameters (sperm percentage, sperm density, sperm motility, normal morphology sperm rate) and seminal plasma neutral α-glucosidase activity at admission were recorded. According to their spouses′ IVF/ICSI outcomes, the 300 patients were divided into the successful pregnancy group (those with successful intrauterine pregnancy detected by ultrasound 30 days after transplantation) and the unsuccessful pregnancy group (those without successful intrauterine pregnancy detected by ultrasound 30 days after transplantation). The differences in sperm DNA integrity, semen parameters and seminal plasma neutral α-glucosidase activity at admission between the two groups were compared. The receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of sperm DNA integrity, semen parameters and seminal plasma neutral α-glucosidase activity in male infertile patients at admission for their spouses′ IVF/ICSI outcomes.Results:According to the IVF/ICSI outcomes of the spouses of male infertile patients, 169 cases (56.3%) had successful intrauterine pregnancy detected by ultrasound 30 days after transplantation; 131 cases (43.7%) had unsuccessful intrauterine pregnancy. At admission, there was no statistically significant difference in clinical data between the two groups (all P>0.05). The DFI and sperm density in the successful pregnancy group were lower than those in the unsuccessful pregnancy group, while the sperm percentage, sperm motility, normal morphology sperm rate and seminal plasma neutral α-glucosidase activity were higher than those in the unsuccessful pregnancy group (all P<0.05). The area under the ROC curve (AUC) values of single indicators including DFI, sperm percentage, sperm density, sperm motility, normal morphology sperm rate, and seminal plasma neutral α-glucosidase level in predicting the IVF/ICSI outcomes of spouses of male infertile patients were 0.719, 0.718, 0.812, 0.779, 0.769, and 0.736, respectively; the sensitivities were 70.42%, 77.46%, 69.01%, 70.42%, 69.01%, and 77.46%, respectively; the specificities were 66.38%, 55.02%, 81.22%, 73.80%, 77.29%, and 62.88%, respectively; the Youden indexes were 0.368, 0.325, 0.502, 0.442, 0.463, and 0.404, respectively; all differences were statistically significant (all P<0.05). Conclusions:Sperm DNA integrity, semen parameters and seminal plasma neutral α-glucosidase activity can assist in predicting IVF/ICSI outcomes, providing an important reference for the treatment outcomes of male infertile patients.
