Fertility preservation has emerged as a leading field in contemporary reproductive medicine, driven by increasing cancer survival rates, delays in childbearing, gonadotoxic treatment protocols, and evolving societal values. Remarkable advances in cryopreservation, vitrification, ovarian tissue transplantation, and sperm preservation have expanded reproductive autonomy and clinical capabilities. This comprehensive analytical synthesis evaluates existing fertility preservation modalities for both female and male populations, examining laboratory innovations, precision medicine integration, assisted reproductive technology, ethical implications, and future translational challenges. Current modalities—oocyte vitrification, embryo cryopreservation, ovarian tissue cryopreservation, sperm banking, and experimental germline stem cell methods—are evaluated on the basis of efficacy, safety, accessibility, and long-term reproductive success. The ethical debate surrounding elective fertility preservation, reproductive justice, and age-related fertility decline is critically examined. This review highlights the urgent need for precise patient stratification, equitable access models, interdisciplinary coordination, and integration of emerging biomedical technologies to optimise fertility outcomes in contemporary reproductive care.
