How to Pronounce Testes

Testes is pronounced TES-teez. Say the first part like the word "test," then add "eez" (rhymes with "breeze") at the end. The stress goes on the first syllable: TES-teez, not tes-TEEZ.

The singular form is "testis" (TES-tis). Since testes is the plural, when you're talking about just one, you say testis instead. It's similar to how "crisis" becomes "crises" in plural.

The word testes breaks into two syllables: TES-teez. The first syllable "TES" rhymes with "test," and the second syllable "teez" rhymes with "breeze."

A common mistake is putting the stress on the second syllable, saying tes-TEEZ instead of TES-teez. Another error is pronouncing it like "test-us" with an "us" sound at the end, when it should end with the "eez" sound.

Testes is the medical term for the two male reproductive glands. In everyday language, people might call them testicles or "balls." The word testes is the formal anatomical name you'll see in medical texts and hear from doctors.

Testes comes from Latin, where "testis" originally meant "witness." The name likely comes from the idea of something that bears witness or proof. The plural form in Latin became "testes," which is the form we use in English medical language.

Words like "testify," "testimony," and "testament" all share the Latin root "test-" meaning "witness." You might also hear "testicular" (tes-TIK-yuh-lar), the adjective form meaning "relating to the testes."

Here's an example: "The testes are located in the scrotum." Or: "Each of the two testes produces sperm." You can also use the singular form: "One testis is larger than the other" (though this is less common in everyday speech).
