Effects of different concentrations of LNG and P4 on the tubal CBF in vitro. a Orthographic views of the ciliary beat frequency following treatment with different concentrations of LNG (one ciliary beat represents one shift from bright to dark on the timeline); b LNG decreased the CBF in vitro in a dose-dependent manner (n = 8 in each group; *, p < 0.05); c orthographic views of the ciliary beat frequency following treatment with different concentrations of P4; d P4 decreased the CBF in vitro in a dose-dependent manner (n = 8 in each group; *, p < 0.05; **, p < 0.01)
