Association between donor gamete use and supernumerary embryo disposition decisions

Area of Science:

• Reproductive Medicine
• Embryology
• In Vitro Fertilization (IVF)

Background:

• Patient decisions regarding the disposition of supernumerary embryos are crucial in assisted reproductive technology (ART).
• Understanding these decisions can inform clinical practice and patient counseling.
• Donor gamete use represents a significant factor influencing reproductive choices.

Purpose of the Study:

• To investigate the association between the use of donor gametes and patient decisions concerning the disposition of surplus embryos.
• To compare embryo disposition preferences between patients utilizing donor gametes versus autologous gametes.

Main Methods:

• Retrospective chart review of 506 patients undergoing IVF at an academic center.
• Analysis of embryo disposition consent forms and demographic data.
• Statistical comparison using Fisher's exact test and logistic regression, adjusting for age, BMI, and nulliparity.

Main Results:

• 18.0% of patients used donor gametes (oocytes or sperm).
• Donor gamete users showed significantly different disposition choices regarding patient death, separation, ART discontinuation, and storage duration (P < 0.05).
• Patients using donor gametes were more likely to opt for embryo research over discarding.

Conclusions:

• Donor gamete utilization is significantly associated with distinct patient preferences for supernumerary embryo disposition.
• These findings highlight the need for tailored counseling based on gamete source in IVF.
• Patient choices reflect varying ethical and personal considerations influenced by gamete origin.
