Yeast Infection

Yeast organisms occur naturally in the genital area. A yeast infection is caused by having too many yeast organisms in the vagina or on the penis.

Yeast infections can spread between sex partners. It is not considered a sexually transmitted infection (STI) because it can occur without having sex.


Vaginal symptoms include:

  • Itching
  • Soreness
  • Burning
  • Thick discharge (similar to cottage cheese)

Penile symptoms include:

  • Itching
  • Rash


Your health care provider can test for yeast infections in the vagina by swabbing the vagina and testing the sample. They can diagnose yeast infections on the penis with a visual exam.


Yeast infections in the vagina can be cured with pills or with medication inserted into the vagina, such as creams or suppositories. Yeast infections on the penis can be cured with pills or with creams applied onto the penis. Many of these treatments are available without a prescription.

Sex Partners

Sex partners do not need to be treated for yeast infections.
