Résumé

PURPOSE: The aim of the study is to report successful outcome (live births) after sperm sorting with annexin V-MACS on cryopreserved spermatozoa with high level of sperm DNA fragmentation from a cancer patient survivor. METHODS: Cryopreserved spermatozoa were sorted with annexin V-MACS prior to ICSI. Sperm DNA fragmentation was evaluated by SCSA((R)) and TUNEL. RESULTS: The couple had two previous IVF/ICSI cycles failures using sperm cryopreserved before cancer treatment. On third ICSI cycle attempt results were as follow: pre-annexin V-MACS sperm quality: 10 x 10(6)/ml, 3.3 % progressive motility, 1 % normal forms, TUNEL: 72.5 % positive cells, SCSA((R)): 76.6 % DFI. Post-annexin V-MACS sperm quality: 2.8 x 10(6)/ml, 10 % progressive motility, TUNEL: 58.8 % positive cells. Eight metaphase II oocytes were collected, 4 fertilized, 2 embryos were transferred on day 3 and healthy twins were born (1 boy, 1 girl). CONCLUSIONS: Annexin V-MACS technique could be a potential tool to improve sperm quality on cryopreserved spermatozoa of cancer patient and improve ICSI outcome.
