Submitted: 6 March 2021 Revised: 21 March 2021 Accepted: 1 April 2021 Published: 15 August 2021 Background: This study aims to compare the effect of tamoxifen (TMX) vs. other regimens on endometrial thickness (EMT), clinical pregnancy, implantation, miscarriage, and live birth rates in women with thin endometrium undergoing frozen-thawed embryo transfer (FET). Methods: We searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, and CINAHL from inception to November 2020 and cross-checked the references of relevant articles. We included randomized controlled trials (RCTs) and nonrandomized controlled trials (non-RCTs) to compare TMX with other regimens for endometrium preparation in women with thin endometrium undergoing FET. We pooled weighted mean differences (WMD) with 95% confidence intervals (CI) for continuous variables (EMT) and odds ratios (OR) with 95% CI for binary variables (i.e., clinical pregnancy rate, implantation rate, and first trimester miscarriage rate). Results: An RCT and three controlled trials (2 beforeafter and 1 retrospective controlled trials) were included in the final review. One study including 154 women and comparing TMX-FET with natural cycle (NC)—FET showed a significant increase in EMT in the TMX cycle (7.87 ± 1.48 mm vs. 6.11 ± 0.98 mm, P < 0.05). Three studies compared the EMT in the TMX and the hormone replacement treatment (HRT) cycles. The pooled analysis showed beneficial effect of TMX on EMT (WMD = 2.06, 95% CI = 1.86–2.27, P < 0.00001). An RCT and a retrospective controlled trial compared TMX and ovulation induction (OI) with Letrozole/human menopause gonadotropin (hMG) for endometrium preparation in women with thin endometrium undergoing FET. No significant difference in clinical pregnancy rates (OR = 1.03, 95% CI = 0.71–1.51), implantation rate (OR = 1.03, 95% CI = 0.76–1.38), or miscarriage rate (OR = 0.91, 95% CI = 0.40–2.06) was observed. No significant difference in EMT was found between TMX and OI with Letrozole/hMG in the included studies. Conclusions: In women with thin endometrium undergoing FET, the use of TMX may result in improved EMT than other regimens. At present, evidence supporting the preferred use of TMX over other regimens as clinical pregnancy rate, implantation rate, or the first trimester miscarriage rate is insufficient.
