1. A sperm collection device, the sperm collection device comprising:
a core member that is made of an elastic material and has an insertion hole for a penis and an insertion space in which the penis inserted in the insertion hole relatively moves inwardly and outwardly; and
a container having an internal space in which the core member is accommodated, wherein
the container includes
a cylindrical base unit that has one end open in an axial direction of the base unit and attached to an insertion-hole-side end of the core member and an opposite end open in the axial direction, and
a cylindrical movable unit that has one end open in an axial direction of the movable unit and an opposite end being closed and is attached rotatably around an axis of the movable unit with respect to the opposite end of the base unit,
the one end of the movable unit overlaps the opposite end of the base unit, and an airflow path is provided in an overlapping part in which the one end of the movable unit overlaps the opposite end of the base unit, and
an adjustment mechanism that adjusts, based on a rotational angle of the movable unit with respect to the base unit, a flow rate of air flowing in and out of the container is provided in the overlapping part.
