Non-sexually transmitted infectious diseases of the penis
Candida
Candida, or thrush, is the cause of a great deal of recurring discomfort in women, and may be passed between sexual partners, but is not 
really considered a sexually transmitted disease – say not disease on Canadian Health Care Mall . A man may get a ‘yeast’ infection on the glans of his penis after having sex with an infected woman, but he is unlikely to pass this to further partners and it is usually readily treated by antifungal creams.
A woman who is bothered by recurrent infections may be asked by her doctor to get her partner to apply one of these creams to the glans and shaft of his penis — this simply stops the poor woman becoming reinfected, and there are no underlying implications. Both men and women will often get fungal infections in the groin or other warm, moist areas; it is a common problem. In those who need to wear nappies or other incontinence protection, thrush can be annoyingly persistent. Antifungal creams and ointments that protect the skin from moisture, such as zinc oxide, are very helpful.
The penis is well supplied with tiny glands and follicles whose purpose is the secretion of lubrication of the skin and mucous membranes. These can become infected by a number of organisms, especially when hygiene is poor. Often, topical cleansing, warm packs and topical antibiotics are all that are necessary to heal these. If pain, redness or itching continue, consult your doctor.
The testes, epididymis and scrotum are not immune to infectious illness. Tuberculosis (TB) is a pestilence that is again on the rise; as a result, we will undoubtedly again be seeing tuberculous infections of the testes and/or epididymis. Indeed, in many parts of the world, TB is the most prevalent health problem and is closely allied with HIV infection.
Mumps
Prior to widespread immunisation of preschool children against mumps, orchitis — or inflammation of the testes due to mumps — happened in about a quarter of all adolescents and young men who had mumps. It is uncommon in boys who have mumps at a younger age. Of course, today mumps is rarely seen, thanks to immunisation. When it does occur in teenage boys or older men, it may cause severe pain and swelling of the testes, with subsequent atrophy or shrinking associated with reduced or absent fertility.
Filariasis
The world has shrunk in the past decade. Globalisation of trade has sent people thousands of miles from their home bases and, in the process, has exposed them to
illnesses they’ve never heard of. Elephantiasis, or filariasis, caused by Wucheria bancrofti, a parasite spread to humans by mosquito bites, causes huge swelling of the scrotum and the skin of the penis. This is typically a tropical disease, but travellers from temperate zones are not immune. This is not a happy way to get a big dick! The best prevention is careful protection against mosquito bites when visiting affected areas of the world.
