Abstract：
Since the inception of in vitro fertilization (IVF), monitoring of controlled ovarian stimulation (COS) has traditionally involved numerous appointments for ultrasound and laboratory testing to guide medication use and dosing, determine trigger timing, and allow for measures to reduce the risk of ovarian hyperstimulation syndrome (OHSS). Recent advances in the field of assisted reproductive technology (ART) have called into question the timing and frequency of COS monitoring appointments, as discussed in this commentary.
摘要：
自从体外受精（IVF）开始以来，传统上，控制卵巢刺激（COS）的监测涉及许多超声和实验室测试的预约，以指导药物使用和给药，确定触发时间，并考虑采取措施降低卵巢过度刺激综合征（OHSS）的风险。辅助生殖技术（ART）领域的最新进展对COS监测预约的时间和频率提出了质疑，正如本评论所讨论的。
