Silva, Luciana Mascena; Lunardi, Franciele Osmarini; Rodrigues, Giovanna Quintino; Girão, Virgínia Cláudia Carneiro; Rodrigues, Ana Paula RibeiroCryopreservation of preantral ovarian follicles is a promising prospect for the preservation of oocyte fertility and oocyte development or in the case of pathologies and therapeutics that may compromise follicular reserves. The great advantage of cryopreservation of ovarian tissue is that it is independent of the age and stage of the menstrual/estral cycle, and involves fewer ethical and social issues. However,...

Silva, Lígia Helena Ferreira Melo e; Silva, João Marcos de Meneses e; Salama, Mahmoud; Pinheiro, Luiz Gonzaga Porto; Lunardi, Franciele OsmariniObjectives: to evaluate estradiol levels and autotransplantation heated ovarian tissue effects, after vitrification, on rats bone metabolism previously oophorectomized bilaterally. Methods: experimental study with 27 rats aged 11 to 12 weeks and weighing 200g to 300g, submitted to bilateral oophorectomy and ovarian tissue cryopreservation for subsequent reimplantation. Animals were divided into two groups, A an...

Lunardi, Franciele Osmarini; Araújo, Valdevane Rocha; Faustino, Luciana Rocha; Carvalho, Adeline de Andrade; Gonçalves, Raphael Fernando BragaThe main objective was to compare the efficiency of vitrification techniques and solutions on the preservation of morphology, ultrastructure and viability of sheep preantral follicles enclosed in ovarian tissue fragments. The fragments were cryopreserved by using macrotube vitrification (MTV), solid-surface vitrification (SSV) or conventional vitrification (CV). These techniques were combined with one of the si...
Histological study of rat ovaries cryopreserved by vitrification or slow freezi...
Silva, João Marcos de Meneses e; Pinheiro, Luiz Gonzaga Porto; Leite, José Alberto Dias; Melo, Lígia Helena Ferreira; Lunardi, Franciele OsmariniPURPOSE: To compare two rat ovary cryopreservation techniques (vitrification vs. slow freezing) and two postmenopausal stages (early vs. late) with regard to graft take.METHODS: Thirty-three Wistar rats were submitted to bilateral oophorectomy. One ovary was submitted to histological analysis while the other was cryopreserved by slow freezing or vitrification. The cryopreserved ovary was thawed and reimplanted ...
