The prefix ovario- refers to which organ?

• A. Ovary
• B. Uterus
• C. Testis
• D. Vagina

Answer: (A)

In medical terms, ovario- is a combining form that designates relation to the ovary, the female reproductive gland that produces eggs and hormones. When you encounter ovario- in a term, it points to the ovary itself. For example, ovarian relates to the ovary, and oophorectomy is the surgical removal of an ovary. This differs from terms for other organs: the uterus uses uter/o or hyster/o, the testis uses orchido- or orchid/o, and the vagina uses vagin/o or colp/o. So the organ referred to by the prefix ovario- is the ovary.
