Impact of the Great East Japan Earthquake and Fukushima Nuclear Power Plant Accident on Assisted Reproductive Technology in Fukushima Prefecture: The Fukushima Health Management Survey

Abstract

Background: The aim of the study was to evaluate the incidences and obstetric outcomes of women who conceived using assisted reproductive technology (ART) procedures in Fukushima Prefecture before and after the Great East Japan Earthquake and Fukushima nuclear power plant accident.

Methods: Information was collected and analyzed from 12,070 women who conceived with or without ART in Fukushima Prefecture during the 9 months before and after the disaster.

Results: During the 9 months before and after the disaster, 138 (2.0%) and 102 (1.9%) women conceived within vitro fertilization-embryo transfer (IVF-ET), respectively. The proportion of women who conceived with IVF-ET decreased during the 2 months immediately after the disaster, but returned to pre-disaster levels 3 months after the disaster. In the case of women who conceived without IVF-ET, the incidences of preterm birth and low birth weight increased after the disaster. In contrast, women who conceived with IVF-ET did not differ significantly in obstetric outcomes before and after the disaster but had a higher incidence of cesarean section and low birth weight compared to those conceived without IVF-ET, regardless of the study period.

Conclusion: The influence of the disaster on woman who conceived using ART procedures was minimal.
