Many a young woman panics when she sees her first menstrual blood, having no idea what it signifies. Her options for dealing with menstruation are unpleasant: thick, rough pads or cotton batting. That may soon change, however. Moscow is negotiating with an American firm to set up a joint venture for the production in the Soviet Union of up to 25 million tampons a year...
