Different Evaluations Exist between Men with Erectile Dysfunction and Their Female Partners When Using Erectile Hardness Model: An Interesting, Observational, and Cross-Sectional Field Survey

Table 5

Erectile function of the men in two groups evaluated by IIEF-5 and Erectile Hardness Model.

	Difference group (n = 238)		No difference group (n = 147)
	Men	Female partner	Men	Female partner
IIEF-5	13.43 ± 5.75	—	16.82 ± 8.23	—
EHS	2.79 ± 0.85^#	2.45 ± 0.63	3.02 ± 0.45	3.02 ± 0.45

Compared with the no difference group, significant differences were found in the difference group. ^#Compared with female partner, significant differences were found in men’s difference group. Difference group = group including couples with different evaluation results of the erectile hardness model; no difference group = group including couples with no different evaluation results of the erectile hardness model; IIEF-5: the 5-item version of the International Index of Erectile Function; EHS: grade evaluated by the model of erectile hardness.
