- PURPOSE: Cryopreservation of a complete ovary may be a future method for fertility preservation in cancer patients. Difficulties exist in cryopreservation of the relatively large ovarian tissue mass. This study evaluates whether a human postmenopausal ovary can be used, as a complement to animal models, in studies of this research field. METHODS: Postmenopausal human ovaries (n=10) were isolated and flushed through ovarian arteries with either the cryoprotectant dimethylsulphoxide or Ringer-Acetate, followed by slow freezing. After thawing, production of androgens during in vitro perfusion and morphology (light/electron microscopy) were assessed. RESULTS: The dimethylsulphoxide-cryopreserved ovaries showed larger secretion of androgens during perfusion than Ringer Acetate-cryopreserved ovaries. Light microscopy showed well preserved morphology in both groups. Electron microscopy revealed normal appearance of stroma and vessels in the dimethylsulphoxide group. CONCLUSIONS: The study demonstrates the potential to use the postmenopausal human ovary for further studies aiming at optimizing cryopreservation protocols, with special reference to ovarian vascularity and stroma.
