“…During warming the vitrified oocytes are removed from their storage location and following the standard operating procedures are submerged in a prewarmed medium containing high sucrose, followed by washing steps in media with a gradually lower concentration of sucrose. The warming process aims to the oocytes' rehydration via osmosis and gradual replacement of the cryoprotectants with water (8). For many, the warming process is more important than cooling as ice crystal formation may also take place during warming and cause cell death (9).…”

Recent advancements in reproductive medicine, specifically in cryobiology and oocyte freezing, have opened new possibilities for women seeking fertility preservation to overcome age-related infertility. This Mini Review aims to outline the expected benefits fertility preservation for non-medical reasons offers to women of advanced maternal age. The review will address current challenges, including determining the optimal number of vitrified oocytes for successful outcomes in planned oocyte cryopreservation, and the need for standardization in the vitrification process. Furthermore, this mini-review will explore concerns and ethical dilemmas arising from the increasing trend of women postponing motherhood, emphasizing the importance of aligning women's expectations with available scientific data to prevent misconceptions and false expectations. Additionally, it will touch upon the welfare of parents and children in light of the increasing age gap among them. Lastly, future developments aiming to enhance the efficiency and accessibility of fertility preservation via automation and the use of AI will be presented.
