Data from: Clinical correlation between erectile function and ejaculatory function in the Czech male population

Introduction The objective of this study is to determine whether there is
any relationship between erectile function (EF) and ejaculatory function
(EJF), with the aim of improving care protocols in the clinical practice.
Materials and methods A total of 1004 Czech males between 15 and 84 years
(42.77 ± 17.556 years) completed a sexual behavior questionnaire. A
correlational, between-subjects design was used, where a 5-item
abbreviated form of the International Index of Erectile Function (IIEF-5)
was used to measure EF, which produces a value between 5 and 25. Values
greater than 21 are considered as a normal function. EJF was measured
using the Index of Premature Ejaculation (IPE). IPE has three domains
(Control, Satisfaction and Distress) with scores from 0 to 100, higher
ones are associated with a greater control and satisfaction, and lower
anxiety, all related to the perception of ejaculation. A linear regression
analysis was performed and a statistics model was proposed for each domain
with EF as a dependent variable and the specific EF domain as a predictor.
The Pearson correlation coefficient was also calculated for these
variables. Results EF scale mean value was 19,44 ± 2,368, control domain
mean value was 80,98 ± 18,032; sexual satisfaction domain mean value was
78,07 ± 21,454; and distress domain mean value was 74,85 ± 34,498. The
results indicate that all linear regression models between EF and each of
the domain of EJF and the Pearson coefficients (r) are statistically
significant (p<0.05). Control r=0,478, p=.001, Satisfaction
r=0,405, p=.001 and Distress r=0,324, p=.002. Conclusions Higher levels of
EF are associated with a better control and sexual satisfaction, and less
distress about ejaculation. This link should be considered for developing
new clinical practice guidelines for erectile dysfunction and premature
ejaculation.
