AMH, anti-Müllerian hormone; FSH, follicle-stimulating hormone; E2, estradiol; P, progesterone; TCM, traditional Chinese medicine; Gn, gonadotropin. indicates a statistically significant difference between the 2 groups of data. The value in bold indicates that the number of high-quality embryos was significantly increased in the EZTG group compared with the placebo group.
