According to the study “Hormonal Contraceptive Use and Persistent Staphylococcus aureus Nasal Carriage” published in Clinical Infectious Diseases, hormonal contraception is associated with a doubled risk of staph colonization.
Yeah, you read that right. In a commentary on the study, it was pointed out that “if the findings hold up in future studies it would mean that about 20 percent of women who carry the bacteria do so because they use hormonal contraception”.
The question that remains unanswered, and the one we are putting out to the scientific community, is why?
Hormonal contraception comes with a similarly doubled risk of HIV. In a panel discussing possible reasons for this doubled risk, it was suggested that “[hormonal contraception] use may disrupt populations of lactobacilli and other microorganisms which in the normal vaginal environment provide protection from certain pathogens, possibly including HIV.”
Staph can be contracted vaginally. Is this the reason for the doubled risk?
Hormonal contraception has been shown to cause significant vitamin B deficiency. In a 2012 study published in Journal of Clinical Investigation, it was strongly suggested that vitamin B3 is an excellent combatant in the fight against staph infection. Perhaps this is the reason?
Whatever the cause, it is disconcerting that something as specifically-purposed as the Pill can have such wide-reaching negative health effects on the women who take them, from staph to HIV, from “increasing overall jealousy” to “a reduction of the frequency of orgasm during intercourse”. We’re still advocating something healthy.
