Abstract

OBJECTIVES: To investigate the effect of gonadotropin-releasing hormone agonist (GnRHa) pre-treatment on the clinical outcomes of fresh and frozen embryo transfers (ETs and FETs, respectively) in infertile patients with adenomyosis. DESIGN: Retrospective cohort study with literature review. SETTING: Peking University First Hospital. POPULATION: We analysed 413 cycles of 369 women with adenomyosis who underwent ETs or FETs. METHODS: We performed logistic regression analysis and meta-analysis to assess the association of GnRHa pre-treatment with the clinical outcomes of ETs and FETs. MAIN OUTCOME MEASURES: The live birth rate (LBR) was compared between patients with and without GnRHa pre-treatment. RESULTS: The LBR was higher in the GnRHa pre-treatment group than in the non-GnRHa pre-treatment group in ETs (41.27% vs. 24.32%, p = 0.034) and FETs (40.36% vs. 20.75%, p = 0.008). The odds of achieving a live birth of women with GnRHa pre-treatment were 2.65 times higher than that of those without (95% CI: 1.19-5.92, p = 0.017) after adjusting for confounders in ETs. Similarly, the adjusted odds ratio (OR) was 2.43 (95% CI: 1.10-5.40, p = 0.029) in FETs. For the meta-analysis, eight studies met the inclusion criteria; however, only six reported the adjusted ORs. Combination of these six adjusted ORs with our results revealed that the GnRHa pre-treatment group had higher LBRs than the non-GnRHa pre-treatment group (ET: OR 1.71, 95% CI: 1.30-2.26, FET: OR 2.61, 95% CI: 1.52-4.49). CONCLUSIONS: In women with adenomyosis, GnRHa pre-treatment may be beneficial for LBRs following both ETs and FETs.
