Discussion
Investigation
• History
• Auxological data
• Pubertal development examination
Mode of Inheritance
• 1 out of every 2,500 female births has Turner Syndrome.
• 45Xo
Turners syndrome XO

• which occurs between two and five years of age
• FDA approved for use in TS in late 1996• 0.375 mg/kg/wk
Estrogen replacement therapy
• started at age 12-15 years• After 6 months progestin can be added
Treatment Conjugated estrogen 0.15 mg/d or 0.3 mg
on alternate day
Ethinylestradiol 0.05 – 0.1 ug/kg/d, 2.5 – 5 ug/d
Adult woman: conjugated E 0.6 – 1.25 mg
ethinylestradiol 10 -20 ug
When spotting occurs or 6 months of treatment with 0.6 mg conjugated E or 10 ug ethinylestradiol
cyclic progesterone should be added 5 – 10 mg 12 – 14 days every month
