1. An assembly comprising:
a straw for the preservation of a predetermined dose of semen, comprising a tube and a gas-permeable liquid-tight stopper, the stopper being disposed in the tube closer to one end of the tube than another end of the tube opposite to said one end, the tube and the stopper being configured for the stopper to be able to slide in the tube towards the other end, wherein said stopper comprises an indicator component having a first predetermined color in the absence of prior contact of the indicator component with said semen and a second predetermined color, having a hue different from the hue of the first color, when the indicator component has been in contact with said semen, and
a controller comprising:
a detector positioned and configured to detect whether said indicator component has taken on said hue of the second color; and
a processor linked to the detector and programmed to emit a signal, after filling of the straw, representing straw mis-filling in case said indicator component as detected by the detector has not taken on said hue of the second color.
