An absorbent article that includes an essentially liquid-impermeable top sheet above an absorbent body enclosed between an upper liquid-permeable sheet and a liquid-impermeable sheet, the top sheet being provided with elastic for shaping the article to the wearer's body and incorporating apertures intended to register with the anus and the urethra orifice of the wearer in use, around which apertures elastically puckered sealing edges are disposed, at least one sealing edge being coated with the sealing medium.
