A recent meta-analysis (simply, a study of studies) shows that medicinal contraceptives are not associated with an increased risk of HIV infection, which is bizarre because only barrier contraceptives, such as condoms, decrease the risk of contracting STDs.
However, one preparation, the infamous Depo-Provera, is associated with increased risk of infection. Now, either the other preparations help prevent infection/inflammation as a side effect (not hard to believe as, modestly, the pill appears to increase the immunomodulator, vitamin D) or Depo-Provera is causing people to test HIV+ itself. Or it could be both.
In any case, this is quite embarrassing for the orthodoxy. They will perhaps conclude that Depo-Provera lowers immunity which increases likelihood of HIV infection, but lowered immunity before infection suggests AID(S) before HIV. And if the other solutions raise immunity they solve AID(S) and therefore HIV-positivity is unlikely.
It’s much simpler to think of Depo-Provera as a direct health threat anything else.
