Message from the Editor-in-Chief

Since receiving an impact factor (IF) for the first time in 2020, Reproductive Medicine and Biology (RMB) continues to show smooth progress: the IF for RMB, which started at 3.239 in 2020, reached 4.009 and 3.4 in 2021 and 2022, respectively. We would like RMB, hailing from Asia, to establish its position as a top journal in this field, along with Fertility and Sterility from the United States and Human Reproduction from Europe.

RMB was born in 2002 as the official journal of the Japan Society for Reproductive Medicine, the Japan Society of Fertilization and Implantation, and the Japan Society of Andrology. In 2016, the Asian Society of Endometriosis and Adenomyosis joined, and in 2020, the Japan Society for Ova Research joined. Today, increasingly more papers are submitted to and published in RMB. Over 60 high-quality invited reviews and original articles appear on RMB every year. All papers that have been published in RMB since its birth in 2002 can be found on PubMed.

To offer further helpful information to our readers, we have launched a new service last year. We now share feature articles focusing on the latest hot topics. Go to the RMB page on Wiley Online Library and click the "BROWSE" tab. Select "Virtual Issues" and you will be able to find these articles. Please have a look.

With more than 400,000 cycles of treatment using assisted reproductive technology (ART) provided per year, Japan is the world's largest nation in terms of reproductive medicine. It is an important mission for us reproductive medicine practitioners and researchers to further advance both research and clinical application in this field and to disseminate information globally. We believe that the further advancement of RMB—a means of communication from Japan—is important in making Japan a global leader in reproductive medicine. We would like to ask for your continued support to develop RMB into one of the world's leading international journals on reproductive medicine published in English.
