Any body part can have an infection, by eliminating it,  you eliminate the future possibility of an infection because the part no longer exist.
We, thankfully, don't remove female parts to prevent infection, although it would reduce infection. The vulva (clitoris, clitoral hood, labia and vaginal vestibule) and vagina are moist female parts that can harbor infection as well as dead cells, urine and numerous secretions.
Just like the vulva of a female, the foreskin plays an important role in sexual function.

Balanitis/ Balanoposthitis

What is Balanitis? Balanitis/ Balanoposthitis are infections of the glans and/or foreskin).

Balanitis simply means a swelling or inflammation of the end of the penis (glans or head). Inflammation most often presents as a redness and/or a blotchy rash of the glans, sometimes with a discharge (this is quite rare). The condition may be accompanied by an itchy or uncomfortable sensation but often feels completely normal.

Posthitis is a similar inflammation of the prepuce (foreskin) and is treated the same way. The two may occur simultaneously - balanoposthitis.

Balanitis can be broken down into several different causes; bacterial infection, fungal infection (thrush), chemical irritation (allergic dermatitis) or eczema/psoriasis. Fungal infections are by far the most frequent, followed by chemical irritations.

Fungal infections are most commonly due to the presence of Candida Albicans - Candidiasis (kandidi´esis)- a normal skin habitant that grows out of control and causes your symptoms. Poor hygiene or poor cleaning under the foreskin of the uncircumcised male can cause or exacerbate the problem. However, excessive cleaning with soaps under the foreskin can have the same effect.

How is Balanitis spread? Where did it come from?

"can I transmit this to my partner" or "is my partner at risk"? Balanitis is not a sexually transmitted disease. It results from an overgrowth of organisms (typically yeast or fungi) which are normally present on the skin of the glans. These yeast are present in both circumcised and uncircumcised men. This being said, the condition most commonly becomes problematic in men who have a foreskin (i.e. have not been circumcised). The environment under the foreskin is warm and moist, and these conditions often favour the growth of the organisms that cause balanitis. In fact, skin candida albicans or mushrooms prefer growth environments that are similar to those ideal to grow edible mushrooms, that is; warmth, humidity and darkness. Obviously, the uncircumcised penis is fertile ground for the occurrence of balanitis. Candida can cause vaginal thrush in women; therefore balanitis in men is sometimes called thrush. However, candida is normally present in both men and women and a man will not automatically develop balanitis if he has intercourse with a woman with thrush.

These organisms are especially likely to multiply and cause inflammation if moisture is allowed to persist under the foreskin. This may occur if you have not washed for a couple of days, or sometimes after sexual activity (vaginal, oral or anal - with or without a condom).

Frequently, the delicate balance between your normal populations of skin bacteria, yeast and the local pH or acidity are thrown off by one or more of these activities, with the result being a loss of control over the populations of yeast and/or bacteria. Your partner's vaginal secretions may cause a local imbalance and subsequent symptoms. In contrast to poor hygiene, improper or overly zealous cleaning may be the problem... harsh/caustic soaps, detergents, shampoos or other body care products may irritate this environment. It is important to evaluate YOUR environment in an attempt to determine the cause in YOUR case.

Bacterial infections are treated with antibiotics. These will be prescribed.

Thrush or Candida (the most common cause) is treated with an antifungal cream that may/may not be combined with a cortisone-based cream. The treatment decision often depends on the severity of your condition. In severe cases of balano(posthitis) we may prescribe a medication to be taken by mouth - let an expert treat you appropriately.
