The gonadotoxic effects of chemotherapy and radiation may result in premature ovarian failure in premenopausal oncology patients. Although autotransplantation of ovarian tissue has led to successful live births, reintroduction of latent malignant cells inducing relapse is a significant concern. In this report, we investigated the design of biomaterial grafts for transplantation of isolated ovar...
INTRODUCTION The aim of this study is to report the current status of ovarian tissue cryopreservation among alternatives for fertility preservation in the Nordic countries. MATERIAL AND METHODS A questionnaire was sent to 14 Nordic academic reproductive centers with established fertility preservation programs. It covered fertility preservation cases performed up to December 2014, standard pro...
BACKGROUND For women facing gonadotoxic treatment, cryopreservation of ovarian tissue with subsequent retransplantation during remission is a promising technique for fertility preservation. However, follicle loss within grafted ovarian tissue can be caused by ischemia and progressive revascularization. Several xenograft models using different immunodeficient rodent lines are suitable for studyi...
Background The aim of this study was to evaluate the effect of L-carnitine as an antioxidant on transplantation of ovarian tissue. MaterialsAndMethods Ovaries from 6-week old mice were grafted into back muscle. Transplanted ovaries were divided into three groups. 150 mg/Kg LC (solved in normal saline) was injected intraperitoneally one hour before surgical operation and repeated one other day u...
BACKGROUND Cryopreservation of the ovarian tissue has shown promising results. However, there remain controversial issues such as the short half-life of grafts. In this aspect, there are some evidences that preconditioning the ovarian tissue before transplantation is beneficial. OBJECTIVE To determine the effect of hypoxic preconditioning in vitro on ovarian tissue prior to transplantation. ...
P-121: Follicle Development in Vitrified Sheep Ovarian Tissue Transplanted to Immunodeficiencent Rat
Background: Ovarian cortex xenotransplantation into immunodeficient rats is a follicles protection method in rare animals and investigation on folliclogenesis. The aim of this study was to evaluate the effects of gonadotropin and erythropoietin (EPO) treatment on follicular development in the transplanted ovaries. Materials and Methods: Prepared sheep ovarian cortical strips were vitrified by c...
BACKGROUND Ovarian tissue transplantation is emerging technologies for fertility preservation. In addition, in vitro maturation (IVM) of oocytes retrieved from ovarian tissues may overcome the fertility defects in certain cases. OBJECTIVE The aim was to evaluate the best site for ovarian tissue transplantation in mice. Also, feasibility of IVM of oocytes retrieved from auto grafted ovarian ti...
Transitional cell carcinoma (TCC) of the urinary tract is the most frequent malignancy following renal transplantation reported in Taiwan. A 67-year-old female underwent bilateral nephrouretectomy and bladder cuff excision because of bilateral hydronephrosis 5 years after cadaveric renal transplantation. The pathologic report was only atrophied kidney. Pelvic sonography and abdominal computed t...
Background/aim: Ovarian transplantation can preserve fertility in cancer patients. The aim of this study was to compare ovarian transplantation into granulation tissue (GT) versus back muscle (BM) sites and also to investigate the effects of N-acetylcysteine (NAC) as an antioxidant on ovarian survival in a rat autograft model.Materials and methods: Twenty-eight adult female rats were divided in...
