Background: Premature ejaculation (PE) is believed to be one of the most common male sexual disorders across all age groups. However its prevalence and risk factors has been rarely investigated among Nigerians. Hence, the study determined the prevalence and risk factors for erectile dysfunction (ED) especially PE among this populace.
Subjects and methods: This cross-sectional survey was conducted on seventy-three (73) males aged 18-75years who were sexually active recruited from the medical out patients clinic (MOPC) of a tertiary health institution. The following instruments were used in the survey: International index of erectile function (IIEF)-5, premature ejaculation diagnostic tool (PEDT) and erection hardness score (EHS) questionnaires. Subjects with hypertension, diabetes, cancer, those with chronic illnesses and those on erection-enhancing agents were excluded.
Results: The mean age of the subjects was 40.15±9.58 years, and all participants identified themselves as heterosexual. The average frequency of sexual intercourse was 7.0±5.49 (median-5.0, IQR-7.0) times/month. This frequency decreased with age (10.0±4.32 in ≤25, 8.28±5.79 in the 2635years, 6.35±5.11 in the 36-45 years, 5.50±5.11 in the 46-55years, P=0.004). The prevalence of erectile dysfunction was 60%, although majority had mild to moderate ED. Premature ejaculation, as assessed by PEDT was present in 24.7% of the participants. It was most prevalent in those younger than 30 years, and decreased with age. We found age-dependent decrease in EHS and frequency of sexual activities. PE was not related to occupation, income, educational level; it was significantly related to age (P=0.002).
Conclusion: There is high prevalence of both erectile dysfunction and premature ejaculation among these Nigerians and premature ejaculation was only related to younger age. Hence, physicians need to be trained to detect, diagnose, and manage PE as well as ED.
