S1P analogue (FTY720‐P)‐induced contractility of rat corpus cavernosum smooth muscle (CCSM) in vitro. Panel A, B and C are FTY720‐P‐induced dose–response force tracings of rats CCSM from sham (A), castration (B) and castration + T (C) groups, respectively. For typical tracings, the x‐axis represents time (min.), while the y‐axis represents force (mg). Panel D is a summary graph for the data shown in panel A–C. Maximal response to KCl was taken as 100%, while the contractility of FTY720‐P was evaluated as a percentage of this response. Values are expressed as means ± S.E. **P < 0.01 versus sham or castration + T. (n = CC strips obtained from 7 to 8 different rats for each group).
