Abstract :


Recent years have witnessed significant advancements in preserving fertility, particularly for women facing conditions detrimental to their reproductive health. Cryopreservation of human gametes, embryos, and ovarian tissues has emerged as a pivotal component of assisted reproduction techniques. This approach not only limits the number of embryos transferred but also allows for the storage of additional eggs and embryos for subsequent treatment cycles. One notable benefit is the reduction in the potential risk of hyperstimulation syndrome associated with cryopreservation.

Cryopreservation techniques primarily involve slow freezing and vitrification. Vitrification, known for its simplicity and success rates, has gained preference over slow freezing in recent times. The slow freezing method has become contentious due to its complexities, costs, and lower success rates in artificial reproduction settings. Consequently, vitrification has emerged as the preferred choice, ensuring successful artificial reproduction without compromising outcomes. Looking ahead, cryopreservation, particularly through vitrification, stands as a promising method in the field of fertility preservation.
