Cancer is not uncommon and no longer considered to be an incurable disorder. 10% of cancer cases occur under the age of 45. There is a remarkable improvement in treatment and survival rates. Today women have been delaying initiation of childbearing because the incidence of most cancers increases with age. Delayed childbearing results in more female cancer survivors. As a consequence there is an...
Ovarian tissue cryopreservation is the key step towards the establishment of an ovarian tissue bank or the preservation of ovarian tissue for patients scheduled for gonadotoxic cancer therapies, aiming for fertility restoration later on. Conventional cryopreservation, or slow freezing, has been the mainstay of ovarian tissue cryopreservation. Vitrification has recently emerged as a new trend fo...
Over the past several decades, considerable effort has been expended toward the successful cryopreservation of various cells. While attempts at cryopreservation have been directed at different tissue types, one of the most vigorously pursued targets has been reproductive tissue. Historically, cryopreservation of sperm has existed for several decades. The earliest reports of pregnancies (Trounso...
BACKGROUND Recently described slow-cooling cryopreservation protocols involving elevated sucrose concentration have improved survival frequencies of human oocytes, potentially overcoming a major hurdle that has limited the adoption of oocyte storage. Because implantation rates of embryos from frozen oocytes remain generally low, it is still debated whether, irrespective of survival rates, this ...
