While the authors noted the link was "statistically significant" they warned it was not enough on its own to justify a complete withdrawal of the drug commonly known by its brand name,Depo-Provera used by millions of women.
The health risk of pulling the medicine from shelves may far outweigh the potential preventable HIV infections the authors argued in a paper published in prestigious medical journal the Lancet infections Disease.
On the statement:Although statistically significant this represents only a moderate increase in relative risk.
The increase in risk was somewhat lower among women in the general population than for those already at higher HIV risk.
Further research was urgently needed to examine the danger for the higher risk women like sex workers and those in a relationship with an HIV positive partner.
But numerous studies have failed to show a direct causal link.
