Interpretation
The association between live birth after IVF and maternal educational level has not been well investigated previously. It remains unclear, whether women’s educational level itself influences the clinical outcomes of IVF. One cohort study of 2569 women indicated that a woman’s educational attainment was not associated with the likelihood of implantation failure, spontaneous abortion, or live birth [19], which is in accordance with our study. However, the women in this study were only divided into three educational categories: no college degree, college degree, and graduate attendance. The classification is fuzzy and does not apply to the current educational system.
