Dr Ginni encounters a man with vitiligo, a condition that strips pigment from the skin, and a woman whose large breasts are giving her back, shoulder and neck pain. Dr Sam meets a woman with painful, recurring mouth ulcers, and another with a rectocele, where the rectum pushes into the back wall of the vagina and forms a bulge. Dr Brad has advice for a woman with missing teeth and infected gums, and a man with onychomycosis, a fungal infection of the nails. There's also a look at the problems caused by excessive earwax, Dr Ginni teaches a group of women how to carry out an examination of the vulva, and Dr Christian has a chat with some men about penis size.
