Changes in societal norms over the last few decades have resulted in novel family planning trends, notably delayed childbearing and increased maternal age at the birth of the first child. Despite advances in reproductive medicine, aging poses significant challenges to fertility. Natural conception in women ≥45 years of age is rare, with high rates of pregnancy loss, and assisted reproduction using autologous oocytes has had limited success. Oocyte donation offers higher live birth rates, exceeding 50%. Elective oocyte cryopreservation could aid in family planning; however, its success depends on the age at which it is performed. These facts highlight the correlation between advancing age and a decline in oocyte quality and quantity. An age-related decline in endometrial receptivity could pose an additional barrier, although evidence for this remains controversial. Furthermore, pregnancies in older women carry high risks for both the mother and child, which should be considered before assisted conception. This comprehensive narrative review examines the advancements in assisted reproductive technology that have expanded the possibilities for delayed childbearing, while simultaneously underlining at the same time the major challenges in the field. Innovations such as ovarian tissue cryopreservation and stem cell-based therapies have the potential to reshape reproductive options for these women. However, thorough counselling and tailored management remain of paramount importance.
