Which of the following is devoid of glands?

The uterus is a pear-shaped muscular organ in the female reproductive system that is primarily responsible for providing a supportive environment for the growing fetus. It becomes highly vascular with a rich supply of blood during the ovulatory phase. However, it lacks glands.

The other parts of the female reproductive system, i.e. the oviducts, vagina, and vulva have glands that serve different purposes. The oviducts have mucus glands that help transport the egg to the uterus, the vagina has lubricating fluid glands, and the vulva has oil glands that keep the skin moist. 

These glands play critical roles in the female reproductive system's health and function.
