Definition

noun one of the two male reproductive glands that produce spermatozoa and secrete androgens

Learned borrowing from Latin testis.

I also noticed some wrasse known as the tapiro, three decimeters long, bony fish with transparent scales whose bluish gray color is mixed with red spots; they’re enthusiastic eaters of marine vegetables, which gives them an exquisite flavor; hence these tapiro were much in demand by the epicures of ancient Rome, and their entrails were dressed with brains of peacock, tongue of flamingo, and testes of moray to make that divine platter that so enraptured the Roman emperor Vitellius. — Twenty Thousand Leagues Under the Seas: An Underwater Tour of the World, Jules Verne
