Average change in ciliary beat frequency (CBF) for ciliary cells in the fallopian tube from mice lacking the PR, after treatment with 100 nM progesterone. After establishment of a baseline frequency the CBF was measured during 60 minutes and the change in CBF calculated as the difference in CBF during the 30 last minutes and the baseline CBF. For each group 10 cells were used from in total 10 animals. For each animal, one cell was allocated to each treatment group.
