Influence of growth hormone supplementation in patients with thin endometrium undergoing frozen embryo transfer

摘要

Objective: To evaluate the effect of recombinant human growth hormone (rhGH) supplementation during hormone-replacement therapy and frozen-thawed embryo transfer (FET) in patients with thin endometrium. Methods: A retrospective research was conducted on 225 patients, who underwent artificial cycle FET in Shanghai, China, between January 2016 and November 2017. Data from 245 FET cycles were analyzed, of which 184 cycles received rhGH (GH group) and 61 did not (control group). Results: Clinical pregnancy and implantation rates were significantly higher in the GH group than those in the control group (64.7% vs. 49.2%, P = 0.032; 44.8% vs. 32.8%, P = 0.019, respectively). After logistic regression analysis, rhGH was considered the only significant variable that influenced clinical pregnancy rate, increasing it by 1.89-fold. On the other hand, the presence of rhGH did not seem to affect the early pregnancy loss. Conclusions: Our results indicated that simultaneous addition of rhGH could improve clinical outcomes of FET in patients with thin endometrium, particularly in patients between 30 and 34 years of age.
