Clinically applied procedures for human ovarian tissue cryopreservation result in different levels of efficacy and efficiency.


PMID 27714478

Abstract

Different protocols are being used worldwide for the cryopreservation of human ovarian tissue for fertility preservation purposes. The efficiency and efficacy of the majority of these protocols has not been extensively evaluated, possibly resulting in sub-optimally cryopreserved ovarian tissue. To address the impact of this issue, we assessed the effects of two clinically successful human ovarian tissue slow-freezing cryopreservation procedures on the quality of the cryopreserved tissue. To differentiate between cryopreservation ( Our experiments revealed that the choice of the cryopreservation protocol noticeably affected the overall tissue viability and percentage of living follicles, with a higher viability after protocol B Our results indicate that extensive and systematical evaluation of clinically used protocols is warranted.
