Ovarian tissue transportation: a systematic review

Abstract In recent years, some countries and fertility preservation networks have started adopting 24-hour transportation schedules for ovarian tissue, a practice that has the potential to spread very fast due to the high costs and bureaucracy involved in establishment of ovarian tissue cryobanks. While pregnancies and live births have been reported after such long periods of transportation, this remains an empirical procedure. Our review aims to prompt reflection on ovarian tissue transport, highlighting our lack of knowledge in humans by providing a counterpoint looking into more than 40 studies published in different animal models. By discussing these studies in animals, we can decipher the findings in various models and shed light on patterns identified. Like the development of different assisted reproductive technology procedures, this is an important step in creating guidelines for future studies into human ovarian tissue transportation.
