BACKGROUND One of the promising methods in fertility preservation among women with cancer is cryopreservation of ovarian cortex but there are many drawbacks such as apoptosis and considerable reduction of follicular density in the transplanted ovary. One solution to reduce ischemic damage is enhancing angiogenesis after transplantation of ovarian cortex tissue. OBJECTIVE The aim of this study...

Chemoradiotherapy has substantially improved life expectancy in young women with cancer, but these treatments often cause infertility. One method of preserving fertility is to cryopreserve ovarian tissue, with subsequent autotransplantation of the tissue after successful anticancer therapy. This study examined the long-term effect of heterotopic transplantation of cryopreserved ovarian tissue o...

Background: With all the recent advances in cancer treatments, many young cancer patients find themselves facing the prospect of losing their fertility after aggressive chemotherapy or radiotherapy. Cryopreservation of ovarian cortical tissue has emerged as a potential option to restore fertility in these young women. Materials and Methods: Because autotransplantation of cryopreserved ovarian c...

Aggressive chemotherapy/radiotherapy and bone marrow transplantation can cure >90% of girls and young women affected by disorders requiring such treatment. However, the ovaries are very sensitive to cytotoxic drugs, especially to alkylating agents. Several options are currently available to preserve fertility in cancer patients. The present review reports the results of 60 orthotopic reimplanta...

Many female patients present with malignant and non-malignant conditions whose treatment causes infertility. Women who are diagnosed with neoplastic diseases before1 or during2 their reproductive years and undergo ootoxic therapies,3 those who undergo an oophorectomy due to non-malignant disorders,4 those of reproductive age at risk for premature menopause associated with genetic disorders, and...

BACKGROUND The risk of recurrent oncological disease due to the reintroduction of cancer cells via autotransplantation of cryopreserved ovarian tissue is unknown. METHODS A systematic review of literature derived from MEDLINE, EMBASE and the Cochrane Library was conducted. Studies on follow-up after autotransplantation; detection of cancer cells in ovarian tissue from oncological patients by hi...

conclusions in iran, hsct has been successfully adapted in routine clinical care. recently, new methods such as double cord blood and haploidentical transplantation have been used to treat many life-threatening diseases. results about 78.2% of the patients (2530 of 3237) remained alive between one to 211 months after stem cell transplantation. nearly, 21.8% (707) of our patients died after stem...

Ovarian transplantation is one of the key approaches to restoring fertility in women who became menopausal as a result of cancer treatments. A major limitation of human ovarian transplants is massive follicular loss during revascularization. Here we investigated whether sphingosine-1-phosphate or its receptor agonists could enhance neoangiogenesis and follicle survival in ovarian transplants in...
