New online submission system beginning in 2021

The online submission system of the Thai Journal of Obstetrics and Gynecology will change from THAIJO to Editorial Manager on January 1, 2021.  The authors, who would like to send the manuscript for consideration for publication in Thai Journal of Obstetrics and Gynecology, should register to the new system.  In addition, the Thai Journal of Obstetrics and Gynecology will increase the issue of publications from four issues per year to six issues per year starting in January 2021 (Volume 29, Number 1).  The increased frequency is a direct response to the volume of high-quality submissions by the researchers.  This will decrease the publication time of each article.
