## Abstract We have examined the effect of 5βhydroxytryptamine (5βHT) on ovaries removed from hamsters and placed in culture 12 or 13 hours after hCG injection. The four responses to 5βHT which were studied include: (1) contraction of follicular smooth muscle cells (SMC), (2) formation of a Vβshape

## Abstract Smooth muscle cells (SMC) of the hamster follicle contract prior to ovulation, and their contraction produces a Vβshaped constriction in the base of the follicle. We have determined when basal constrictions first appear in follicles removed from females at various preovulatory times by
