Cancer treatments can induce premature ovarian failure in almost half of young women suffering from invasive neoplasia. Cryopreservation of ovarian cortex and subsequent autotransplantation of frozen-thawed tissue have emerged as promising alternatives to conventional fertility preservation technologies. However, human ovarian tissue is generally harvested before the administration of gonadotox...
BACKGROUND Because higher survival of follicles during the freezing/thawing procedure improves the quality of cryopreserved tissue reimplanted after oncological therapies, defining an optimal method for human ovarian tissue cryopreservation remains a major issue in this field. One option to improve the cryopreservation procedure is to use better materials, i.e., vials with better conductivity. ...
OPINION STATEMENT With improving survival rates for pediatric and young adult cancer patients, considerations regarding the long-term effects of therapy have become more important. Cancer therapies are known to pose reproductive risks, though the effects may be unpredictable. All at-risk patients should have a discussion about potential treatment-related infertility before the onset of cancer t...
background: many attempts have done to improve cryopreservation of mammalian ovaries using simple, economical and efficient technique “vitrification”. objective: the aim of the present study was to compare the mouse ovaries cryopreservation by direct cover vitrification (dcv) using different concentrations of ethylene glycol (eg) with conventional vitrification methods (cv). materials and metho...
At present, there are three ways to determine effectively the quality of the cryopreservation procedure using ovarian tissue before the re-implantation treatment: evaluation of follicles after post-thawing xenotransplantation to SCID mouse, in-vitro culture in a large volume of culture medium under constant agitation and culture on embryonic chorio-allantoic membrane within a hen's eggs. The ai...
