THE contraceptive pill is polluting the environment and is in part responsible for male infertility, a report in the Vatican newspaper L'Osservatore Romano said on Saturday.

The pill "has for some years had devastating effects on the environment by releasing tonnes of hormones into nature" through female urine, said Pedro Jose Maria Simon Castellvi, president of the International Federation of Catholic Medical Associations, in the report.

"We have sufficient evidence to state that a non-negligible cause of male infertility in the West is the environmental pollution caused by the pill," he said.

The article was promptly dismissed by several organisations.

"Once metabolised, the hormones contained in oral contraceptives no longer have any of the characteristic effects of feminine hormones," said Gianbenedetto Melis, vice-president of a contraceptive research association.
