Men's age determines sexual and reproductive health services utilisation in Ekiti State, Nigeria

•Most previous studies on sexual and reproductive health have its focus on women thus excluding men who are major stakeholders in ensuring sexual and reproductive health. In this study, opinions of men on determinants of sexual and reproductive health services utilisation were established.•Our study found that utilisation of SRH services by men was poor and this was majorly due to barriers that were service provision related. The study established that age is a major determinant of SRH utilisation by men as active reproductive aged-men utilised sexual and reproductive health services than other groups.•The study therefore highlights the need for policy change that will allow healthcare services to deliver age-specific and attractive sexual and reproductive services for men.

Data were analysed with SPSS IBM statistics version 26 and the statistical significance was set at p-value < 0.05. Only 18 % had previously utilised SRH services. Age was the only predisposing characteristic found to be associated with SRH service utilisation (p = 0.02) while distance of hospitals to participants’ residence and distance of hospitals to participants’ office were enabling characteristics found to be significantly associated with SRH service Utilisation (p = 0.00 and p = 0.04), respectively. Prevention and treatment of HIV (p = 0.03) and prevention and treatment of male sexual dysfunction (p = 0.01) were the need-based characteristics associated with SRH service utilisation. Binary logistic regression analysis showed that only age (OR = 1.40, 95 % C. I=1.03–1.90, p = 0.03) was the significant determinant of SRH service Utilisation with middle-aged men utilising SRH services more than other age groups.
