A significantly lower rate of good-quality embryos was observed in the hysteroscopy group compared to the non-hysteroscopy group (50.38% vs. 75.11%,\n                      <jats:italic>p<\/jats:italic>\n                      &amp;lt; 0.05). After adjusting for embryo quality, age, BMI, AMH, duration of infertility, and endometrial thickness, multivariable analysis confirmed that the hysteroscopy group had a significantly higher clinical pregnancy rate (OR: 1.51, 95% CI: 1.142\u20131.997,\n                      <jats:italic>P<\/jats:italic>\n                      = 0.004) compared to the non-hysteroscopy group.
