C-IVF: Conventional stimulation IVF; MS-IVF: Minimal stimulation IVF
There were also no significant differences in the live birth rate and miscarriage rate between two groups. As minimal stimulation on average has only one dominating follicle each cycle and on average only one embryo transferred subsequently, the multiple pregnancy rate in MS-IVF was significantly low, only 0.001%.
To address potential confounding variables, multivariable logistic regression analysis was used to assess whether clinical results, particularly clinical pregnancy rate was affected by age, BMI, basal FSH level, AMH level and AFC count, as well as stimulation protocol. As a result, it showed that clinical pregnancy rate was only affected by age, AMH level and AFC count.
