Ethical considerations and management strategies for fertility preservation in women of reproductive age with malignant tumors: Chinese practices and perspectives
To review the ethical and regulatory landscape of fertility preservation for reproductive-aged women with cancer in China, while comparing international practices.
Key Findings:
Frozen mature oocytes have an 80%-90% survival rate post-thawing and a cumulative live birth rate of about 33%.
Embryo freezing is the most established technique but is limited to married patients.
Ovarian tissue freezing shows a 37.7% pregnancy/live birth rate post-transplantation but carries a 1% risk of tumor cell reintroduction.
In vitro maturation has a significantly lower live birth rate (8.9%) compared to mature egg freezing.
Patients express a high need for fertility information (66%-100%), with anxiety and depression impacting decision-making.
Multidisciplinary collaboration can optimize treatment timing but actual referral rates remain low.
Ethical challenges include decision-making autonomy, rights to frozen gametes, offspring health follow-up, and social equity.
Interpretation:
Limitations:
Legal gray areas exist for unmarried patients regarding egg freezing and disposal rights.
Public attitudes towards the use of frozen gametes for research are divergent.
