The word "asexualize" means to remove the reproductive capacity of an organism or to cause it to become asexual. As a result, it has no exact antonyms. However, some words can be used to describe the opposite of asexual reproduction, such as sexual reproduction, fertilization, and procreation. In biology, the term "hermaphrodite" refers to organisms that have both male and female reproductive systems. In social contexts, the opposite of asexual might be considered sexual or romantic, depending on the context. Overall, while there is no direct antonym for asexualize, words describing the opposite processes or behaviors can be used instead.
