Background: Oocyte, embryo and ovarian tissue cryopreservation are proposed for fertility preservation to cancer patients who hope to be mothers after getting rid of the disease. Materials and Methods: Embryo cryopreservation is not possible for unmarried single girls without sperm partner and oocyte retrieval is a long time procedure. Thus ovarian tissue cryopreservation is suggested for ferti...

Background Fertility preservation is an important part of scientific study in the field of reproductive medicine. Ovarian cryopreservation and in vitro follicles culture provide option for fertility conservation in older women or cancer patients. Basic fibroblast growth factor (bFGF) or FGF-2, is member of fibroblast growth factors family which play critical roles in cell migration proliferatio...

abstract ovarian tissue freezing or cryopreservation might be the only acceptable method for preserving the young women fertility, before radiotherapy or chemotherapy. this technology might be used for patients with recurrent ovarian cysts or endometriosis, without ovarian stimulation. many efforts have made to improve cryopreservation conditions that should be seriously considered for cancer p...

Background: DZN (diazinon) is an organophosphate insecticide that had been used in agriculture and for domestic and veterinary use for several years and caused many negative effects on plants and animal species, especially on human. The aim of present study was to evaluate the effects of DZN on MDA (malondialdehyde) and GSH (glutathione) levels in female rat reproductive tissue (ovary) and to...

background: the purpose of this study was to compare the three different strategies, intravenous (iv) hydroxylethyl starch (hes), iv human albumin (ha), and oral cabergoline (cb) in the prevention of ovarian hyperstimulation syndrome (ohss). materials and methods: in this prospective randomized clinical trial, 91 women at high risk of developing ohss were allocated into the three groups, group ...

Background This study aimed to assess follicle survival after xenotransplantation of sheep ovarian tissue into male and female immunodeficient rats. We evaluated the effects of gonadotropin treatment on follicular development in the transplanted tissue. MaterialsAndMethods In this experimental study, sheep ovarian cortical strips were transplanted into the neck back muscles of 8 male and 8 fema...

the majority of cancer treatments are invasive. gonadal injuries cause reductions in fertility which results in lack of hope for conception in cancer patients and frustration for their partners. fortunately, current advancements in cryopreservation and transplantation sciences regarding fertility preservation lead to cryostorage of gonads and preservation prior to the onset of chemo- and radiot...
