Men over 40 who have Type 2 diabetes may face an increased risk for developing penile yeast-based infections. The word “yeast infection” generally refers to a vaginal infection caused by the yeast Candida albicans, and less commonly other Candida species, including C. glabrata, C. parapsilosis, C. tropicalis, and C. krusei.
A yeast infection of the penis is called candidal (or candida) balanitis, or balanitis thrush. Causes and Risk Factors of Candidal Balanitis or Penile CANDIDIASIS: Unlike with vaginal yeast infections, penile yeast infections are usually sexually acquired – when a man has sex with someone who has a yeast infection. Treating Penile YEAST-BASED INFECTIONS (Yeast Infection in Men)Like vaginal yeast infections, penile yeast infections are easily treated with antifungal drugs called azoles.
- Symptoms of Male Yeast Infections (Candidal Balanitis) Burning and itching around the top of the penis, which worsens after making love. Redness and swelling. Small, rash-like bumps called papules, which might have pus. Pain during urination or sex.
- Early symptoms of a penile yeast infection often add a red rash and sometimes white, shiny patches on the penis. Your skin on the penis may be moist, and a thick white substance may be found under the foreskin or other folds of skin. You may also experience itching and a burning feeling on your penis.
- Thrush is a common candidiasis that affects women and men.
- As with vaginal thrush, the reason for thrush in men is an overgrowth of the yeast-like fungus, Candidiasis.
What Causes Yeast Infections In Men?
Yeast-based infections in men are common because the fungus that triggers yeast-based infections (candida) is generally present on skin, especially moist skin. When some contributing factor – such as having sex with a female partner that has a vaginal yeast infection – causes an overgrowth of candida, infection can result. 
Is Yeast Infection Contagious To Your Lover?
Most yeast-based infections are not contagious. Infrequently, the candidiasis can be transferred between women and men during intercourse. However, since most yeast-based infections aren’t transferred from person to person, a yeast infection in the vagina or penis/foreskin is not considered to be a std (STD).
What Does A Yeast Infection Look Like?
Vaginal yeast infection symptoms commonly include: Itchiness in the vaginal area and around the vulva (the opening of the vagina) Swelling of the vulva. White or grey vaginal discharge that may be thick (sometimes referred to as looking like cottage cheese) but does not have an awful smell.
