More than a third of Japanese males aged between 16 and 19 have no interest in or are actively averse to sex, according to a government survey.
Japan's birth rate stands at 1.21 per family, far below the rate of 2.08 babies that is required for a stable population.
As of March 2009, Japan's total population stood at just over 127 million, but that figure is projected to decline to 95 million by 2050.
