There are a number of proposed causes for the development of<unk> . The aetiology of<unk>  can be both organic (biological) or psychogenic (psychological) in nature. In males, however, organic causes are rare and psychogenic causes are more common.<unk>  is described as having three main variants, related to the level of anatomical change. The most common presentation of the condition is characterized by a normal adult larynx and an increased pitch due to the vocal folds adopting the falsetto position. A second variant can occur when the laryngeal development is prolonged during puberty. Lastly,<unk>  can occur due to an incomplete transformation of the larynx into the adult form. Psychogenic causes * Emotional stress * Delayed development of secondary sex characteristics *Resistance to pubertal changes * Self-consciousness resulting from an early breaking of the voice *Self-consciousness resulting from emerging adulthood *Excessive admiration of another male or sibling *Excessive maternal protection Organic causes * Laryngeal muscle tension which then causes laryngeal elevation * Muscle incoordination * Congenital anomalies of the larynx * Vocal fold asymmetries * Unilateral vocal fold paralysis * Non-fusion of the thyroid laminae. When this is the case, it is important that hypogonadism is ruled out, as this may be the cause.
