[Non-obstructive XXXX : option of the testicular sperm extraction performed on the day of oocyte retrieval].

@entity1 @entity35076 @entity3893
OBJECTIVE: Analyzing the results and validating the procedure of testicular sperm extraction (TESE) performed on the day of oocyte retrieval in non obstructive @entity3893 (NOA) @entity1 . @entity1 AND METHODS: Sixty TESE were performed on the day of oocyte retrieval ( @entity35076 ), in 52  NOA @entity1 . @entity1 were sorted into three groups according to the results of the surgical procedure: 1: sperm recovery with possible sperm freezing (n=20); 2: sperm recovery without freezing (n=27); 3: "negative" biopsy (n=13). ICSI outcomes in the two groups with sperm recovery were compared to those of ICSI performed with frozen-thawed sperm obtained from TESE performed (n=13). RESULTS: The rate of positive sperm retrieval was 78%. While the overall clinical pregnancy rate was 50%, no difference in the fertilization, implantation and clinical pregnancy rates was found in the two groups with positive sperm retrieval as compared to frozen-thawed sperm group. Twelve pregnancies were obtained in @entity1 without further sperm cryopreservation. CONCLUSION: After TESE in NOA @entity1 , cryopreserved sperm produced comparable results with freshly obtained sperm. However, TESE performed on @entity35076 can offer the opportunity, in @entity1 with rare sperm that might not survive freeze-thaw, to have a possible fresh embryo transfer. Couples should be counselled regarding the possibility of oocyte retrieval without sperm for ICSI.
