However, the related mechanisms were unclear.</p><p><strong>Methods: </strong>A total of 18,561 patients, who underwent fresh IVF-ET cycles in the Center for Assisted Reproduction of Jiangxi Maternal and Child Health Hospital from January 2014 to September 2021, were retrospectively analyzed. The propensity score matching (PSM) technique was used to control for confounding factors between the GnRH-ant and GnRH-a groups. Human endometrial stromal cells (hESCs) were collected for primary culture and treated with relevant receptor antagonists and activators.

The result showed that the endometrial thickness (10.4 ± 2.35 <i>vs.</i> 11.03 ± 2.61 mm, <i>p</i> < .001) on trigger day was significantly lower in the GnRH-ant group.
