Babies with TS tend to be small at birth, growth through childhood is slow and there is no pubertal growth spurt.
The physical examination includes determination of pubertal development in adolescents, a neurological exam (which may reveal a neuromuscular cause), and measurements of trunk asymmetry.
Normal pubertal development and spontaneous menstrual periods do not occur in the majority of children with Turner syndrome.
However, it is estimated that 3 to 8 percent of girls with a single X chromosome and 12 to 21 percent of females with sex chromosome mosaicism may have normal pubertal development and spontaneous menstrual periods.
Developmental factors such as pubertal timing, self-esteem, and peer affiliation may also increase their risk of exposure to STDs.
