Age, BMI, Gonadotropin and Sex Hormone Levels in Males With Prader–Willi Syndrome (PWS)

	PWS total		PWS deletion type I		PWS deletion type II		PWS UPD

Age (years)	24	26.5±8.7	8	26.8±4.1	6	26.7±11.5	10	26.2±10.3	0.989^*
BMI (kg/m²)	24	35.0±9.0	8	35.2±9.6	6	36.3±9.3	10	34.0±9.1	0.889^*
FSH (mIU/ml)	24	13.4±14.8	8	12.3±11.0	6	27.1±22.0	10	7.0±4.9	0.010^**
LH (mIU/ml)	24	2.9±2.4	8	1.7±2.0	6	4.9±3.3	10	2.6±1.1	0.019^**
Testosterone (ng/ml)	23	1.5±1.4	8	1.1±1.0	5	1.4±1.6	10	1.9±1.7	0.543^**

Normal reference range: follicular stimulating hormone (FSH) for ≥16-year-old males—0.7–11.1 mIU/ml; lutenizing hormone (LH) for ≥16-year-old males—0.8–7.6 mIU/ml; testosterone for ≥16-year-old males—2.45–18.4 ng/ml.

P-values calculated by using one-way ANOVA.

^**

P-values calculated by using univariate analysis among all three genetic subtype groups (deletion type I, deletion type II and UPD) adjusting for age and BMI.
