BACKGROUND Ovarian tissue preservation is proposed to patients at risk of premature ovarian failure, but this procedure still needs to be optimized. To limit injury during ovarian tissue cryopreservation, anti-apoptotic drugs were added to the transport and freezing media of ovarian cortex tissue. METHODS Sheep ovaries were transported, prepared and frozen in solutions containing vehicle or a...

Advances in the diagnosis and treatment of cancer have resulted in a growing population of adolescent and adult long-term survivors of malignancies with infertility problems due to induced premature ovarian failure. Although several options are currently available to preserve fertility in cancer patients, cryopreservation of ovarian tissue is the only option available for prepubertal girls and ...

BACKGROUND Breast cancer is a frequent indication for ovarian cortex cryopreservation due to its high incidence. The main concern of this procedure is the possibility of reintroducing metastatic cells within the implant, an issue that has not been addressed systematically. Thus, a study was designed to analyse the presence of ovarian metastases in breast cancer patients undergoing ovarian tissu...

Animal experiments have shown that cryopreservation of the ovarian cortex, containing primordial follicles, could be used to preserve gametes thereby restoring fertility in humans and animals. During the last 100 years, many hundreds of species have been lost, and a third of the breeding animals are threatened with extinction. To preserve genetic diversity, notably for the conservation of endan...

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...

STUDY QUESTION Is sucrose more effective than trehalose in human ovarian tissue cryopreservation? SUMMARY ANSWER The effect of sucrose as a cryoprotective agent (CPA) was not significantly different from that of trehalose in human ovarian tissue cryopreservation. WHAT IS KNOWN ALREADY Sugars have the ability to keep the cell membrane intact and can decrease the toxicity of CPAs. Sucrose is ...
