[The correlation between sperm DNA damage and IVF-ET clinical pregnancy outcomes in different BMI population with normal routine semen examination].
OBJECTIVE: To analyze the correlation between sperm DFI, HDS and IVF-ET pregnancy outcomes in different BMI populations with normal routine semen examination.
METHODS: The clinical data of 199 cycles of IVF-ET were retrospectively analyzed. Sperm chromatin structure analysis based on flow cytometry was used to detect sperm DFI and HDS. The correlation between sperm DFI, HDS and pregnancy outcome of IVF-ET were analyzed.
RESULTS: The sperm DFI was negatively correlated with IVF-ET pregnancy in overweight (24.0 kg/m2≤BMI<28.0 kg/m2) population (OR=0.935, P=0.043). In the normal BMI group (18.5 kg/m2≤BMI < 24.0 kg/m2), the clinical pregnancy outcome of IVF-ET was not significantly correlated with sperm DFI, and was negatively correlated with male age (OR=0.744, P=0.020). In the obese population (BMI ≥ 28.0 kg/m2) , there was no significant correlation between the clinical pregnancy outcome of IVF-ET and sperm DNA fragmentation index (DFI) , but a negative correlation with male BMI (OR = 0.779, P = 0.043).
CONCLUSION: The male BMI affected the correlation between sperm DFI and IVF-ET pregnancy outcomes: ①Sperm DFI was only associated with IVF-ET clinical pregnancy outcome in the overweight population; ② In normal BMI and obese populations, male age and male BMI were important factors affecting IVF-ET clinical pregnancy outcome respectively; ③No correlation was found between sperm HDS and IVF-ET pregnancy outcomes.
