Andersson-Wallgren G et al. - When given to TS girls, GH and androgen normalized SFF and reduced voice and articulation problems in adulthood. The TS phenotype includes important voice and speech problems, which in turn are associated with hearing problems, although genotypic, monosomic, and isochromosome patients have more voice problems and also more high-pitched voices than mosaic patients. Most TS women, despite their karyotype or age, exhibit a higher frequency of pitched voice than non-TS women.
