Cycle Characteristics and Reproductive Outcomes of FET
The Cycle Characteristics and reproductive Outcomes of FET are presented in Table 2. Endometrial thickness and its increase are significantly greater in TAM group (8.98±2.02vs8.15±1.11, 2.82±2.21 vs2.2±1.59). Nonetheless, the duration of endometrium preparation was shorter in TAM group than HRT group. The distribution of best embryos transfer was comparable between the two groups (p=0.481).The clinical pregnancy rate, implantation rate, ongoing pregnancy rate and live birth rate were significantly higher in TAM group than HRT group. The miscarriage rate was similar between the two groups (11.8% vs.14.0%; p=0.701).
After adjusting the results for the above-mentioned potential confounders (Table 3), the CPRs, OPRs and LBRs remained consistently higher [adjusted odds ratio (aOR), 95% CI] in TAM group compared with HRT group[CPR(aOR1.820, 95% CI1.219-2.72), OPRs(aOR1.640, 95% CI1.090-2.467) LBRs(aOR1.570, 95% CI1.018-2.420)].
