Methods Patients with obstructive azoospermia with an age distribution of 20-36 years old admitted to the male department of the Reproductive Center of the Second Affiliated Hospital of South China University (Hengyang Nanhua Xing Hui Reproductive Health Hospital) from December 2018 to December 2020 were used in this study. One group was set up as the PESA group to perform percutaneous epididymal sperm aspiration, and the other group was set up as the TESA group to perform percutaneous testicular biopsy for sperm extraction. Patients who were unsuccessful in PESA continued to undergo TESA, and if sperm were retrieved, they were classified as the TESA group. Finally, there were 26 patients in the PESA group and 31 patients in the TESA group. Embryo development (normal fertilization rate, high-quality embryo rate, high-quality blastocyst rate) and pregnancy outcome (clinical pregnancy rate, miscarriage rate, and ectopic pregnancy rate) were compared between the two groups. Results The rate of high-quality blastocysts in the TESA group was significantly higher than that in the PESA group (P < 0.05); the differences in clinical normal fertilization rate, high-quality embryo rate, clinical pregnancy rate, miscarriage rate and ectopic pregnancy rate between the two groups were not statistically significant (P > 0.05). Conclusion ICSI with different sources of sperm in patients with male factor infertility alone, which had no significant effect on embryo development, embryo implantation rate, clinical pregnancy rate, and miscarriage rate, and resulted in better clinical outcomes
