FERTILITY PRESERVATION: ADVANCES IN CRYOBIOLOGY, REGENERATIVE, AND NANOMEDICINE STRATEGIES – AN OVERVIEW : EMERGING TRENDS IN FERTILITY PRESERVATION

Abstract

The need to preserve fertility has now become a fundamental part of reproductive medicine
due to the developments of cryobiology, regenerative medicine, nanomedicine and new
biotechnologies. Optimised cryopreservation protocols can improve the viability and
preservation properties of gametes and gonadal tissues, and nanotechnology can be used to
target the delivery of protective factors and provide real-time monitoring of the reproductive
organs. Decellularised scaffolds, 3D bioprinting, and stem cell therapy are regenerative
techniques that offer biomimetic platforms that aid in vitro folliculogenesis,
spermatogenesis, and tissue regeneration. New biotechnological methods, including
CRISPR-based gene editing and in vitro gametogenesis, have the potential to fix genetic
infertility and increase the resilience of the germline, but ethical, legal, and societal issues
are of high concern. Artificial intelligence and machine learning also maximise fertility by
foretelling gamete and embryo quality, personalised treatment direction, and better assisted
reproductive technology success rates. The pediatric, adolescent, and transgender
populations demand particular attention, and their strategies should consider the
development stage, hormone treatment, and specific clinical requirements. Future studies
must focus on the following: longitudinal studies, standardisation of technology,
translational pathways so as to ensure safety, reproducibility and fair access. The
combination of these multidisciplinary innovations alongside patient-centred and ethically-
driven solutions can be used to redefine the concept of fertility preservation through the
provision of safe, effective, and personalised solutions to individuals at risk of reproductive
compromise.
