The tampon has a body formed of an absorbent material (6), and having at least one zone containing a solid hydrophobic substance (7) that has a melting point that is greater than 37 degrees Celsius (C) and that at least partially impregnates the absorbent material of the tampon. The solid hydrophobic substance limits expansion and/or absorption by the zone when the body of the tampon contacts an absorbable fluid.
