Virilism, also known as masculinization, is a medical condition that results in the development of male characteristics in females. This condition is caused by an excessive production of androgen hormone, which leads to symptoms such as deepening of voice, facial hair growth, acne, and increased muscle mass. There are several synonyms for virilism, including androgen excess syndrome, hyperandrogenism, and androgenization. Additionally, the condition may also be referred to as virilization, hirsutism, or masculinization syndrome. While treatments are available to manage the effects of virilism, early detection and diagnosis are essential in order to prevent irreversible damage to the body.
