What does balantitis indicate?

Balantitis is a medical term specifically denoting inflammation of the glans penis, which is the head or tip of the penis. This condition can arise due to various factors, including infections (such as from bacteria or fungi), irritants (like soaps or lotions), or underlying medical conditions such as diabetes. The inflammation can lead to symptoms such as redness, swelling, and pain in the affected area, which directly corresponds to its definition.

Other conditions mentioned in the choices pertain to different anatomical sites or symptoms. For instance, the infection of the testicles relates to a completely different issue known as orchitis, while difficulty in urination and pain during ejaculation are symptoms that could relate to a variety of other urological conditions rather than balantitis itself. Thus, recognizing that balantitis specifically refers to inflammation of the glans penis clarifies why this choice is the most accurate.
