A yeast infection is a common fungal infection caused primarily by the overgrowth of a yeast called Candida albicans. This fungus naturally lives on the skin and inside the body without causing issues. When the natural balance of microorganisms is disrupted, the yeast can multiply excessively, leading to uncomfortable symptoms. Many people wonder about the transmissibility of this condition, especially between intimate partners.
How Yeast Infections Are Transmitted Between Partners
Yeast infections are not classified as Sexually Transmitted Diseases (STDs) because they can occur in people who are not sexually active. Despite this, the infection can be transferred between partners during intimate contact, including vaginal, anal, and oral sex. The friction and moisture involved in sexual activity can facilitate the transfer of the Candida fungus from one person to the other.
Transmission is more likely when one partner has an active infection and sex occurs without barrier protection. While yeast can be passed in either direction, factors like micro-abrasions in the skin during sex, a weakened immune system, or the use of antibiotics can increase the likelihood of transmission. Abstaining from sex during an active infection is generally recommended to prevent passing it on.
Recognizing Symptoms in Different Partners
The symptoms of a yeast infection differ depending on the biological sex of the partner who contracts it. In female partners, the most common signs include intense itching and a burning sensation in and around the vagina. This is often accompanied by a thick, white, odor-free vaginal discharge that is frequently described as having a cottage cheese-like appearance.
Male partners can develop candidal balanitis, which is inflammation of the head of the penis. Symptoms may include redness, a persistent itching or burning sensation, and a rash on the glans penis or under the foreskin. Uncircumcised male partners are at a higher risk because the warm, moist environment beneath the foreskin encourages yeast growth. Male partners can sometimes be asymptomatic carriers, harboring the yeast without showing symptoms, which complicates detection and can lead to recurrent infections in their partner.
Immediate Treatment Options
Once an infection is suspected, seeking professional medical diagnosis is the first step to confirm the presence of Candida and rule out other conditions like bacterial vaginosis or STDs. Treatment typically involves antifungal medications, which come in several forms. Over-the-counter (OTC) options for female partners include creams and suppositories containing antifungals, which are inserted directly into the vagina for a course of three to seven days.
A healthcare provider may prescribe a single-dose oral antifungal pill, such as fluconazole, for a more convenient treatment. Topical antifungal creams are generally the treatment for male partners experiencing symptoms of balanitis. To prevent the infection from being passed back and forth, it is often necessary for both partners to be treated simultaneously, even if one partner is not showing any symptoms.
Preventing Future Transmission
Several simple, proactive measures can significantly reduce the risk of future transmission between partners. The most straightforward strategy is to avoid all intimate contact during an active yeast infection until the symptoms have fully resolved and the course of treatment is completed. While not foolproof, using barrier methods like condoms during sexual activity can help minimize the physical transfer of yeast.
Prevention also involves specific hygiene habits. This includes wearing cotton underwear and loose-fitting clothing to keep the genital area dry, as Candida thrives in warm, moist environments. Avoiding the use of scented hygiene products, such as perfumed soaps or douches, can help maintain the natural microbial balance that keeps yeast growth in check.
