Effect of repeated controlled ovarian stimulation on pregnancy outcomes in fresh embryo transfer cycles: a retrospective cohort study
The number of COS cycles did not significantly adversely affect pregnancy outcomes across different populations. In self-controlled comparisons within the same population, repeated COS (≤ 5 cycles) may not impair ovarian reserve function, while repeated COS (≤ 4 cycles) positively influenced clinical pregnancy outcomes, suggesting a potential cumulative effect.
