Table 4.

Gonadotropin and sex steroid levels according to breast morphological stage as determined by ultrasound.

Breast Morphological Stage	LH (IU/L)	FSH (IU/L)	E2 (pg/mL)	E1 (ng/dL)	TT (ng/dL)	AD (ng/dL)
A	0.05 (0.04–0.07)	1.14 (0.98–1.77)	1.22 (1.22–3.08)	0.46 (0.39–0.59)	6.59 (3.09–8.53)	22.39 (13.47–30.31)
B	0.10 (0.06–1.42)	1.64 (0.94–2.77)	2.21 (1.22–5.01)	0.78 (0.52–3.01)	8.76 (5.53–11.21)	23.67 (18.12–34.04)
C	0.27 (0.08–1.52)	2.54 (1.87–4.03)	5.96 (1.22–11.38)	1.04 (0.63–1.72)	9.19 (5.96–11.58)	35.72 (26.73–50.44)
D	1.81 (1.22–3.37)	4.31 (3.48–5.36)	15.85 (8.78–33.65)	2.23 (1.70–2.86)	16.60 (13.75–22.99)	68.93 (51.56–89.53)
E	1.95 (0.77–3.04)	3.96 (2.86–5.31)	20.46 (6.28–29.58)	2.12 (1.54–2.95)	11.79 (9.27–20.07)	61.58 (46.84–81.37)

Data is presented as median (IQR). All hormones increased linearly with breast maturation, p<0.001. To convert E2 to SI units (pmol/L), multiply by 3.67; for E1 (pmol/L), multiply by 3.69; for AD (nmol/L), multiply by 0.0349; for TT (nmol/L), multiply by 0.0347.
