Age and treatment changes in tremor amplitude. Tremor amplitude increased with age at 9 Hz (7 to 22 months, P = 0.015) and 12 Hz (P = 0.017) and decreased with transplantation of young ovarian tissue at 9 Hz (CTL 22 months to GC 22 months, P = 0.009 and to GD 22 months P < 0.001) and 12 Hz (CTL 22 months to GC 22 months, P = 0.009 and to GD 22 months P < 0.001) at all frequencies. CTL 22mo (n = 5) = age-matched controls, GC 22 months (n = 4) = received germ cell containing 60-day ovaries at 13 months. GD 22 months (n = 8) = received germ cell depleted 60-day ovaries at 13 months. Error bars represent SE
