LONDON - A team of international scientists says today that a male contraceptive pill that has been tested in a two year trial in 15 centres around the world has proved effective in 99 per cent of men.
Doctors said the only disadvantage was that weekly injections were needed, but trials were underway to administer it with longer term injections or a skin patch. The contraceptive secretes the male hormone testosterone into the body to reduce the sperm count to a negligible amount.
