Egg freezing as a fertility preservation technology raises Islamic family law concerns, particularly regarding marital status, lineage, and the use of stored reproductive material following changes in family circumstances. This study examines the legal status of egg freezing for Muslim women and its relationship to the regulation of assisted reproduction in Indonesia. It employs a normative legal method based on library research, using conceptual, statutory, and maqāṣid al-sharī‘ah approaches. The findings indicate that the legal status of egg freezing cannot be determined categorically but must be assessed in light of the purpose of preservation, the stage of reproductive use, and the continuation of the marital relationship. Medically indicated egg freezing has a relatively stronger basis in public benefit, whereas non-medical egg freezing requires more careful assessment without being automatically deemed prohibited. Its subsequent use for reproduction must take into account marital validity, the origin of gametes, the site of embryo transfer, and applicable storage requirements. This study proposes a staged normative assessment distinguishing oocyte retrieval and storage, fertilization and embryo transfer, and the continuation of storage or use after marriage ends. This framework reconciles the protection of women’s health and reproductive potential with the principle of ḥifẓ al-nasl and Indonesian health regulations. It also identifies that elective egg freezing before marriage is not separately regulated for every possible scenario under the current framework governing assisted reproduction.
