Quantitative measurements from Masson’s trichrome staining

	Sham SHR (n = 6)	ESWT SHR (n = 8)
Collagen, %	51 ± 4.1	38 ± 5.6
Smooth muscle, %	29 ± 3.5	43 ± 6.2
Ratio smooth muscle/collagen	0.6 ± 0.1	1.9 ± 0.6
Total cavernosal area, mm2	3.38 ± 0.12	3.87 ± 1.5

Effect of Li-ESWT protocol delivered by Aries on cavernosal histology in SHR. Masson’s trichrome staining was performed on penis section of rats who received (SHR_ESWT) or not (sham) the Li-ESWT protocol. The amount of collagen and smooth muscle fibers is expressed as percentage of the total area of cavernosal tissue. Data are mean ± standard error of the mean.

Li-ESWT = low-intensity extracorporeal shock wave therapy; SHR = spontaneously hypertensive rat.
