Causes of Penile Yeast Infection

Penile yeast infections occur when there is an abundance of yeast on the skin or in the body. There are a number of factors that can contribute to an overgrowth of yeast in males, including both environmental factors and overall health conditions. Being knowledgable about the causes of male yeast infections will better enable you to prevent an infection alltogether.

Yeast needs a warm and moist place to thrive and the groin and penis area on a man provides this environment – especially penises that are uncircumcised. Because the foreskin is still attached, moisture can get trapped on the underside, which can be a haven for yeast to hide and reproduce.

Below you will find information on the most common ways that men contract yeast infections.

Sexual Intercourse

Penile yeast infections can be caused by unprotected sexual intercourse with an infected female partner, even though yeast infections aren't really classified as a sexually transmitted disease. The occurrences of this are rather uncommon, but it has been known to happen. Additionally, condoms that are used for protection from such infections can actually cause penile yeast infections themselves. This happens when the person wearing the condom has an adverse reaction to the lubricants used in the condoms or the latex from the condom itself.


Antibiotics or other medications that cause fluctuations in the body's normal levels of good bacteria can lead to a yeast infection. The medications are prescribed to combat invading bacteria that causes other illnesses, but also kills off the body's good, yeast-fighting bacteria in the process.

Unhealthy Diets

Poor diets, such as diets that are high in sugar and carbohydrates, can contribute to causing yeast infections because they both encourage yeast production within the body by being food sources for the yeast. People with compromised immune systems due to serious illnesses like cancer or HIV/AIDS are at an increased risk of developing yeast infections because their bodies are not able to effectively fend off the invading yeast organisms.


Poor hygiene can be a cause of penile yeast infections, especially in men who are not circumcised. This is because the foreskin is still attached, making thoroughly cleaning the penis difficult. The foreskin should be pulled back during the bathing process to ensure that the penis is properly cleaned. Otherwise, secretions can build up, producing a conducive environment where yeast can grow and invade the penis.

Other Conditions

Alternately, penile yeast infections can be caused by an underlying condition. Frequent yeast infections are common in people who have diabetes and are often the first warning sign of diabetes in people who have yet to be diagnosed.
