More procreant refers to the ability to reproduce or produce offspring in a greater number or with greater frequency. Its antonyms, on the other hand, refer to the inability or decrease in the ability to reproduce. Some antonyms for more procreant include barren, infertile, sterile, unproductive, and non-reproductive. These words describe a lack of fertility in both humans and animals. In addition, the term celibate can also be considered an antonym, as it denotes the choice to abstain from sexual activity altogether, thereby eliminating the possibility of procreation. Overall, the antonyms for more procreant describe the opposite of the capability to reproduce, which can occur for a variety of reasons, including age or medical conditions.
