What does gonadectomy mean?
Gonadectomy is a surgical term for removal of a gonad, the reproductive gland that produces sex cells and hormones. Because gonads can mean testes or ovaries, the word covers procedures performed on either type of gland, although the more specific terms orchiectomy and ovariectomy are generally preferred when the organ is known. In clinical writing, gonadectomy may also refer to the removal of both gonads at once, though the expression should be read carefully if “bilateral” is not stated. The term appears in discussions of cancer treatment, hormone-sensitive conditions, veterinary care, and certain gender-affirming surgical procedures. It is more technical than the broader lay term castration, which can also mean methods that destroy or suppress reproductive function without removing a gland. Its Greek and Latin components make its meaning transparent: gonad refers to a reproductive gland, and -ectomy denotes cutting out or excision. For readers, gonadectomy is especially useful as an umbrella term when the precise type of gonad is not the point of discussion.
nounThe surgical removal of a gonad, which may be a testis or an ovary. The term may also refer to removal of both gonads when the procedure is bilateral.
- The surgical removal of a testis or ovary, or of both gonads as a bilateral procedure.
"The dog underwent a bilateral gonadectomy as treatment for a testicular condition."
"The patient underwent a gonadectomy to treat malignant disease in the affected gonad."
"Gonadectomy is also used in some gender-affirming surgical procedures."
The plural is used when referring to multiple surgical removals of gonads or to the procedures collectively.
"The surgeon explained the risks associated with bilateral gonadectomies."
A vasectomy interrupts a reproductive duct; a gonadectomy removes the gland itself.

Where does gonadectomy come from?
Gonad comes through New Latin from the Greek gónos, meaning “seed” or “semen.” Gonadectomy combines this term with the Greek-derived surgical suffix -ectomy, associated with éktomē, “excision” or “cutting out.”
How gonadectomy is actually used
This is a specialized medical and surgical term. It is broader than the lay term castration and more technical than ordinary descriptions of removing reproductive organs.
Easily confused with gonadectomy
