Serum Testosterone Concentrations and Circulating Bone Turnover Markers after Sham Surgery (T₉ Laminectomy) or Severe Spinal Cord Injury (SCI) Alone or in Combination with Testosterone-Enanthate (TE) or TE Plus Finasteride (TE+FIN)

	SHAM (a)	SCI (b)	SCI+TE (c)	SCI+TE+FIN (d)
Testosterone (week 4), ng/mL	3.7 ± 0.8^c,d	1.9 ± 0.5^c,d	6.8 ± 0.5^a,b,d*	10.0 ± 0.9^a,b,c*
Testosterone (week 8), ng/mL	3.3 ± 0.7^c,d	1.5 ± 0.3^c,d	7.8 ± 1.5^a,b	10.9 ± 1.6^a,b
Trap5b, U/L	3.4 ± 0.2^c*,d	2.9 ± 0.1	2.4 ± 0.2^a*	2.8 ± 0.3^a
P1NP, ng/mL	26 ± 3	34 ± 4^c*,d	21 ± 2^b*	24 ± 2^b

Values are means ± standard error; n = 7–12/group.

Letters a–d indicate differences from respectively labeled groups at p < 0.05 or *p < 0.01 (a = vs. SHAM, b = vs. SCI, c = vs. SCI+TE, and d = vs. SCI+TE+FIN). Trap5b is a circulating marker of bone resorption. P1NP is a circulating marker of bone formation.

Trap5b, tartrate resistant acid phosphatase 5b; P1NP, procollagen type 1 N-terminal propeptide.
