Age, reproductive hormones, and testicular volume differences between groups, which were grouped according to follicle-stimulating hormone level, with Mann–Whitney U-test

	Normal FSH group (n=231)	Elevated FSH group (n=172)	P
Age (year)	28.00 (26.00, 31.00)	28.00 (26.00, 31.00)	0.552
INHB (pg ml⁻¹)	111.12 (79.84, 145.03)	13.60 (11.00, 21.85)	<0.001
LH (IU l⁻¹)	4.82 (3.26, 6.32)	9.25 (7.25, 11.50)	<0.001
T (ng dl⁻¹)	466.00 (351.00, 634.70)	331.85 (255.75, 444.80)	<0.001
Testicular volume (ml)	13.20 (12.00, 15.00)	10.00 (8.23, 12.00)	<0.001

Data were shown as median (upper quartile, lower quartile). INHB: inhibin B; FSH: follicle-stimulating hormone; LH: luteinizing hormone; T: testosterone
