Background While the assisted reproductive technology (ART) relieves the burden of infertility in many couples, it presents significant public health challenges due to the substantial risk for multiple birth delivery and preterm birth, which are associated with poor maternal and fetal health outcomes. For this reason, it is important to monitor the development and effectiveness of ART services in Thailand. Objective To analyze the trends of ART services in Thailand between 2008 and 2014. Methods ART clinics in Thailand are required to submit data to the Royal Thai College of Obstetricians and Gynecologists via the National Reporting System. The data from 2008 to 2014 were collected and analyzed. Results The number of ART centers was increased from 35 to 47. The total fresh ART cycles were also increased from 3,723 to 6,516. The percentage values of intracytoplasmic sperm injection (ICSI), in vitro fertilization, gamete intrafallopian transfer, and zygote intrafallopian transfer cycles were changed from 77.87 to 95.59, 21.43 to 4.31, 0.21 to 0.09, and 0.45 to 0.05, respectively. The clinical pregnancy rates were 28.79–33.19, 22.84–51.34, 14.29–42.86, and 0.00–26.67, respectively. The clinical pregnancy rates in fresh vs. frozen-thawed cycles were 31.01–36.33 vs. 31.54–37.34 ( P  &lt; 0.05). The clinical pregnancy rates in female age &lt;35 vs. 35–39 vs. ≥40 years were 36.97–40.70 vs. 32.74–33.42 vs. 21.08–31.34, respectively ( P  &lt; 0.001), and the percentage values of multifetal pregnancy rate were 18.75 vs. 13.30 and 13.69, respectively ( P  &lt; 0.001). There were increasing preimplantation genetic screening (PGS) cycles, with the percentage of the clinical pregnancy rate (25.90–42.63,  P  &lt; 0.05). The clinical pregnancy rates in medium-sized ART centers (100–300 cycles per year) vs. in small and large centers were 30.79–41.14 vs. 28.01–34.04 and 8.70–40.35, respectively ( P  &lt; 0.001). Trends of increasing percentage of ART birth rate to total birth rate ratio were 0.24–0.34 ( P  &lt; 0.05). Conclusions There were higher clinical pregnancy rates in frozen-thawed cycles. Higher multifetal pregnancy rate and clinical pregnancy rate were also found in younger females. There were increasing uses of ICSI and PGS. A trend toward increasing ART birth to total birth ratio was observed.
