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...

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: 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 a...

Ovarian tissue transplantation is an experimental procedure that can be used to treat both infertility and premature menopause. Working within the current legal framework in the USA, I examine whether ovarian tissue should be legally treated like gametes or organs in the case of ovarian tissue transplantation between two women. One option is to base classification upon its intended use: ovarian...

Ovarian tissue autotransplantation is an innovative fertility preservation technique that has provoked ongoing investigations. The purpose of the present study was to assess safety and reproductive performance ovarian autotransplantation. This review conducted according PRISMA guidelines. Seven studies met inclusion criteria. A total 3427 patients underwent cryopreservation 205 received Tissue ...

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...

background and aims: ovarian cancer is one of most common causes of cancer related women's mortalities. human papilloma virus is a known factor concerning cervical cancer but its role in causing ovarian cancer is not yet verified. a few studies also identified hpv dna in ovarian carcinoma tissues. however, some studies did not detect hpv dna in ovarian carcinoma tissues. in this article, we inv...
