Victor-Bryan Nwala, a medical doctor, has warned against using saliva as lubricant during sexual intercourse because it might lead to yeast infection, among others.

Nwala took to his Twitter page to disclose that the practice could cause sexually transmitted infections.

He listed herpes, gonorrhea, chlamydia, HPV, syphilis, and trichomoniasis as diseases that could be transmitted to the genitals through saliva.

The doctor warned that the bacteria in saliva is different from those in the vagina, and its introduction to the reproductive organ could lead to yeast infection or bacterial vaginosis.

“Saliva is not a lubricant! The result can upset your vaginal microbiome and leave you susceptible to developing yeast infection or bacterial vaginosis,” he warned.

“Any STI in the throat or mouth can be transmitted to the genitals through saliva.

“If your partner has an active herpes lesion, for example, using the spit to ‘make things slick’ could leave you with genital herpes.

“This scenario happens more than you might think and it is the most common way genital herpes is contracted.

“Even if you don’t see a cold sore on or around the mouth, the virus can still be transmissible.

“Herpes isn’t the only oral STI you could contract. Gonorrhea, chlamydia, HPV, syphilis and trichomoniasis can also all be transmitted to the genitals through saliva.”
