Menstrual cups comprise a resilient body having an open top and a closed bottom and defining an internal volume sized to hold menstrual fluid. The resilient body comprises a wall structure that extends from the open top to the closed bottom. The wall structure has an outer surface opposite the internal volume and an inner surface facing the internal volume. The resilient body is biased to an open conformation, and the resilient body has a longitudinal axis that extends through a center of the internal volume when in the open conformation.
