What does uniparous mean?
Uniparous is a formal zoological adjective describing an organism that produces a single offspring at a time. Its meaning concerns each reproductive event, not necessarily an entire lifetime: an animal may have several uniparous pregnancies over its life. The term is especially used in zoology and reproductive biology when comparing one-offspring patterns with multiparous reproduction, in which multiple offspring are produced together. It can modify a female, a species, or a reproductive system, depending on context. In ordinary conversation, uniparous is uncommon and may sound clinical or literary rather than everyday. Knowing the word nevertheless helps in biological texts, where distinctions among reproductive strategies matter. Its compact formation also makes it memorable: uniparous combines a prefix meaning one with the birth-related root found in familiar compounds such as biparous and oviparous.
adjectiveProducing a single offspring at a time; characterized by one offspring per reproductive event.

"The uniparous female gives birth to a single offspring in each reproductive cycle."

Uniparous is the zoological opposite of multiparous: one offspring at a time rather than several together.

Where does uniparous come from?
Uniparous was formed in English from the combining form uni-, meaning “one,” and the element -parous, meaning “giving birth” or “producing offspring.” The latter comes through Latin parere, “to bring forth,” the same root underlying compounds such as biparous, multiparous, primiparous, and viviparous.
