No, the human vagina does not have a bone. The vagina is a muscular and tubular structure that is part of the female reproductive system. It is made up of layers of muscle tissue and connective tissue, and its walls are lined with mucous membranes. The vagina is designed to be elastic and flexible to accommodate various functions, including sexual intercourse, childbirth, and the passage of menstrual fluid.

Unlike some parts of the skeleton, there are no bones within the structure of the vagina. Instead, it relies on muscular support and the surrounding pelvic bones for structural integrity and function. The vaginal muscles can contract and relax, allowing for changes in size and shape as needed for different activities and stages of a woman’s life.
