What is the meaning of the combining form “orchi/o”?

The combining form "orchi/o" refers specifically to the testis. In medical terminology, "orchiectomy" is a procedure involving the removal of one or both testicles, indicating the root's connection to male reproductive anatomy. The prefix "orchi-" comes from the Greek word "orchis," which means "testicle." This foundational understanding is essential in various contexts within medicine and health discussions regarding male reproductive health.

The other options represent different anatomical structures: "ovary" pertains to the female reproductive system, "uterus" refers to the organ that houses and nourishes a developing fetus during pregnancy, and "pancreas" is involved in digestive and metabolic functions. Therefore, the correct association of "orchi/o" solely with the testis highlights its specific use in medical vocabulary concerning male reproductive health.
