There were no significant differences in serum levels of FT3, E2 and TT between ED patients with SCH and the controls with euthyroidism (all P>0.05, Table-IV), while the serum concentrations of TSH and PRL were significantly higher, and FT4 was significantly decreased in ED males with SCH than euthyroidism controls (all P<0.05, Table-IV). Here, PRL is linked to spindle cell hemangioma.
