Men could one day use a contraceptive which uses the body&#39;s immune system to prevent conception, say researchers. Scientists, from the University of North Carolina, immunised male monkeys with a protein found in the testes which made them infertile.

Scientists in Massachusetts said today they had created several colonies of human embryonic stem cells without harming the embryos from which they were derived, the latest in a series of recent advances that could speed development of stem cell-based treatments for a variety of diseases.

They report that they injected nine male macaque monkeys with Eppin, a protein from the testes. Seven became infertile, and of these five became fertile again when the treatment stopped.
