Tired of vaginal infections? Oral s*x may be causing it

Experts say this sexual act can significantly increase the risk of catching or passing on sexually transmitted diseases (STDs) including HIV, herpes, syphilis, gonorrhea, HPV, and viral hepatitis.

BV Pulse

A recent study published in the journal PLoS Biology found a link between oral sex and a common vaginal condition called bacterial vaginosis or BV.

The study suggested that mouth bacteria can affect the microbes that live and grow in the vagina and contribute to the development of BV.

Bacterial vaginosis is not a sexually transmitted infection. It is actually an imbalance of the usual bacteria found in the vagina. Usually, it doesn't cause any symptoms, but some women who have it may get a strong-smelling discharge.

The danger with BV

Bacterial Vaginosis is quite common among women. It may not seem serious as it doesn't cause any severe symptoms, but it can make you more vulnerable to catching sexually transmitted diseases and getting urinary infections. If you're pregnant, it increases the risk of having a premature birth.

How would you know if you have bacterial vaginosis? An unusual discharge that has a strong fishy smell is the most prominent sign of BV. You may also notice a change in the colour and consistency of your discharge, such as becoming greyish-white and thin and watery.

A swab test can determine if you have bacterial vaginosis or not. If you have it, your doctor may prescribe antibiotic tablets, gels or creams.

Oral sex and bacterial vaginosis

The study in PLoS Biology suggested that Fusobacterium nucleatum, a common type of bacteria found in the mouth, may support the development of bacterial vaginosis. The mouth bacterium is linked with gum disease and dental plaque.

The research team from the University of California conducted experiments in human vaginal specimens and in mice to look at the bacterial behaviour. The mouth bacterium appeared to aid the growth of other bacteria implicated in BV, they said.

The findings concluded that oral sex might contribute to some cases of BV.
