Virilise is a term that describes the development of masculine characteristics within an organism. There are a number of synonyms that can be used to convey a similar meaning, such as masculinize, androgenize, or testosterone-ize. These terms all suggest the introduction or stimulation of male hormones or traits, leading to the development of features such as deeper voices, increased muscle mass, and more body hair. In agricultural contexts, the term is often used to describe the process of inducing male traits in female plants or animals to increase yield or productivity. Other related terms might include virility or manliness, which connote the same idea of a strong, masculine presence.
