  1. *Area measured, but no significant difference between males and females were found.
  2. __ Area did not show specific staining within song nuclei on film or on slides, and therefore was not quantified.
  3. †17β-HSD4 = 17-beta-hydroxysteroid dehydrogenase type IV; SNX2 = Sorting Nexin 2
  4. aMagnitude of sex difference (Male mean/female mean)
