Epididymitis is infection or less frequently, inflammation of the epididymis (the coiled tube on the back of the testicle). The majority of men that develop epididymitis develop it because of a bacterial infection. Although males of any age can develop epididymitis, it occurs most frequently between ages of 20 to 39. When it develops in children, it is usually due to inflammation caused by trauma.

In mammals, the vagina is a muscular and tubular part of the female genital tract, which, in humans, extends from the vulva to the cervix. The outer vaginal opening may be partly covered by a membrane called the hymen. At the deep end, the cervix (neck of the uterus) bulges into the vagina.
