Without a testis or testicles; describing organisms or individuals lacking functional testes.
From the prefix 'a-' meaning without plus 'testine' from Latin 'testis' meaning testicle. This medical/biological term specifically describes the absence of male reproductive glands.
This is a niche medical term that's rarely used in practice because doctors usually just say 'no testicles,' but it's in medical dictionaries as the proper anatomical descriptor.
