Patients' views on the embryo storage time limits.

Area of Science:

• Reproductive Medicine
• Bioethics
• Health Policy

Background:

• Embryo storage duration is often determined by socio-political factors, not patient preferences.
• Global regulations and healthcare policies regarding embryo cryopreservation vary significantly.
• Patient understanding of embryo storage limits and the rationale behind them is often limited.

Purpose of the Study:

• To assess patient opinions on embryo storage time limits.
• To understand patient perceptions of the criteria used to establish embryo storage periods.
• To identify knowledge gaps and misconceptions regarding embryo cryopreservation.

Main Methods:

• Mixed-methods study involving quantitative questionnaires and qualitative interviews.
• Survey of 534 in vitro fertilization (IVF) patients in Portugal (August 2011 - December 2012).
• In-depth interviews with 34 couples undergoing IVF treatment.

Main Results:

• 38% of patients preferred a 4-5 year storage limit, 38% preferred over 5 years, and 23% preferred 3 years.
• Previous IVF cycle experience correlated with preference for longer storage durations (>5 years).
• Having children was inversely associated with women's preference for longer embryo storage.

Conclusions:

• Patient preferences for embryo storage duration are diverse and influenced by personal experiences.
• A significant portion of patients lack sufficient knowledge about embryo cryopreservation and storage policies.
• Addressing misconceptions and improving patient education on embryo storage is crucial for informed decision-making and policy development.
