Objectives: Recent demographic changes, such as marriage at later ages and delayed childbearing, have contributed to the increased demand for ovum donation. The purpose of the present study was to evaluate the frequency and impact of egg donation deliveries on maternal care using a questionnaire survey of Japanese perinatal care providers.
Methods: A quantitative survey was conducted from October to November 2012 using self-administered anonymous questionnaires. We asked 2,693 obstetrics clinics/hospitals throughout Japan to complete the survey: 679 questionnaires were returned (response rate, 25.2 %).
Results: Of the respondents, 15.8 % answered that they had handled egg donation deliveries in the past. With regards to the country in which patients received egg donation services, the most frequent was the United States, including Hawaii. Asian countries, such as Thailand, Korea, and Singapore, were also reported; only two cases in Japan were reported. "Advanced age/menopause" was the most frequent reason for egg donation, and the mean age at egg donation delivery, because of advanced age/menopause, was 48.3 years.
Conclusions: Our findings will increase public awareness of the legal issues related to assisted reproductive technology and cross-border reproductive care, as well as care of the mother and child in pregnancies resulting from reproductive technologies such as egg donation overseas. People should be aware of the issues involved in egg donation abroad and the resulting deliveries, and should implement specific care for women bearing children at later ages.
