Vaginal yeast infections are a common concern that many experience at some point in their lives. These infections can cause discomfort and can sometimes be linked to sexual activity.

Below, we’ll explore what yeast infections are, what causes them, how they can be related to sex, and ways to prevent and treat them effectively.

What Is a Vaginal Yeast Infection?

A vaginal yeast infection, medically known as candidiasis, occurs when there is an overgrowth of the fungus Candida, typically Candida albicans. This fungus naturally lives in various parts of the body, including the mouth, throat, gut, and genital areas. When the balance of bacteria and yeast in the body is disrupted, Candida can grow excessively, leading to an infection.

Yeast infections most commonly affect the vaginal area. Symptoms include itching, irritation, and a thick, white vaginal discharge that resembles cottage cheese. Vaginal yeast infections are very common and can be triggered by a number of different factors.

What Causes Yeast Infections?

Several factors can contribute to the development of a yeast infection. The most common causes of vaginal yeast infections include:

  • Antibiotics: The use of antibiotics can disrupt the natural balance of bacteria in the body, killing the beneficial bacteria that normally keep yeast growth in check, thereby allowing yeast to overgrow.
  • Hormonal changes: Fluctuations in hormone levels, such as those that occur during pregnancy, with the use of birth control pills, or during menopause, can create conditions that favor yeast overgrowth in the vaginal area.
  • Diabetes: Elevated blood sugar levels associated with diabetes can create an environment that promotes yeast growth, making individuals with diabetes more susceptible to infections.
  • Weakened immune system: Conditions that compromise the immune system, such as HIV or the effects of treatments like chemotherapy, can reduce the body's ability to fight off yeast, leading to overgrowth and infection.
  • Diet: Consuming a diet high in sugar and refined carbohydrates can fuel yeast growth, as yeast feeds on sugar, increasing the likelihood of developing an infection.

Can You Get a Yeast Infection from Sex?

Yes, it is possible to get a yeast infection from sexual activity, but vaginal yeast infections are not classified as sexually transmitted infections (STIs). The friction during sex can irritate the vaginal area, making it more susceptible to a yeast overgrowth. Additionally, if one sexual partner has a yeast infection, it can be passed to the other during intercourse.

How to Prevent Yeast Infections After Sex

Preventing yeast infections after sex involves a few simple steps:

  1. Maintain good hygiene: Wash the genital area before and after sex.
  2. Wear breathable underwear: Wearing cotton underwear helps to keep the area dry and reduce yeast growth.
  3. Avoid scented products: Scented soaps, lubricants, and feminine hygiene products can disrupt the natural balance of bacteria and yeast.
  4. Use protection: Condoms can reduce the risk of transmitting or developing a yeast infection.

FAQ: Sex & Yeast Infections

Can you get a yeast infection from oral sex?

Yes, it is possible to get a yeast infection from oral sex, especially if your partner has oral thrush (a yeast infection in the mouth). The fungus can be transferred to the genital area during oral-genital contact.

How do you know if you have a yeast infection or a STD/STI?

While yeast infections and STIs can share some symptoms, such as itching and discomfort, yeast infections typically cause a thick, white discharge and intense itching without the presence of sores or foul-smelling discharge that are often associated with STIs. If you are unsure, it’s best to connect with a doctor.

Can you spread a yeast infection to your partner?

Yes, yeast infections can be spread to your partner during sexual activity. Both men and women can develop yeast infections after sexual contact with an infected partner.

Is it your partner's fault you got a yeast infection?

Not necessarily. While yeast infections can be spread through sexual contact, they are often caused by factors unrelated to your partner, such as antibiotic use or hormonal changes.

Can you still have sex if you have a yeast infection?

It’s generally not recommended to have sex while you have a yeast infection, as it can be uncomfortable and may worsen the infection or spread it to your partner. It’s best to wait until the infection has cleared.
