Objectives: To review the management with assisted reproductive technologies (ART) of men with congenital bilateral absence of vas deferens (CBAVD), associated with cystic fibrosis or not, after surgical retrieval [epididymal aspiration (MESA) or testicular biopsy (TESE)].
Methods: Multicenter retrospective study made of 2 groups: CBAVD and cystic fibrosis (CF) or CBAVD only (CF-RD). Two centers performed MESA (Brest and Nantes) and one TESE (Rennes). Sperm numeration, motility, vitality, morphology and nuclear maturity were measured in both centers performing MESA. Fertilization rate (TF) and cumulated progressive pregnancy rate by retrieved oocyte (TGC) were compared between centers following ART.
Results: Ninety patients underwent surgical retrieval between January 1996 and March 2013, 30 in the CF group and 60 in the CF-RD group. Semen parameters were comparable between groups and centers. Fifty-eight (22 in the CF group and 36 in the CF-RD group) patients received ART between April 1996 and October 2014. TF was 50% and 52% and TGC 26% and 32% in the CF group and CF-RD groups, respectively. The results did not differ between groups but TGC was higher in Rennes than in the other two centers.
Conclusion: Both semen parameters and ART results are comparable and similar to those reported in the literature. As shown by the results obtained in Rennes, TESE seems to be more effective.
