Natural aphrodisiacs consumption by male workers in the former Katanga province, DR Congo

BackgroundIn a previous cross-sectional study to determine the prevalence and determinants of erectile dysfunction (ED) among artisanal mineworkers, we found a significant association between ED and consumption of locally produced plant-derived aphrodisiacs. AimWe aimed to investigate the type and mode of consumption of aphrodisiacs, their possible health effects, and reasons for use among male workers in the Katanga province. MethodsWe conducted a mixed method study, first doing a survey (March 2021) among a convenience sample of 127 artisanal miners and 122 collective taxi-drivers. Participants responded to the International Index of Erectile Function (IIEF) questionnaire and had measurements of serum urea, creatinine, hepatic enzymes, total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides and sexual hormones. In a second qualitative phase, 16 participants, i.e., eight miners and eight drivers were interviewed. ResultsSelf-reported regular (at least once a week) consumption of aphrodisiacs was significantly more prevalent among taxi-drivers (75%) than among miners (47%). Mild-to-moderate and moderate ED were reported more frequently by aphrodisiacs consumers [20/152 (13%)] than non-consumers [6/97 (6%)]. Five types of plant-derived aphrodisiacs (Zingiber officinale, Mitragyna stipulosa, Ocimum sp, Piper nigrum, Securidaca longepedunculata) were consumed, via the oral or anal routes, sometimes together with alcohol. We found no evidence of nephrotoxicity, hepatotoxicity or disturbances in serum levels of sex hormones. Themes that emerged from interviews related to cultural perceptions about masculinity, with miners using aphrodisiacs to support failing erectile function, and taxi-drivers taking aphrodisiacs for preventing ED. ConclusionWe found a high prevalence of plant-derived aphrodisiacs use among working men in Katanga. While no serious adverse effects were identified, more ethno-botanical studies with isolation and rigorous identification of active constituents are needed to provide the poor population with correct information and to protect them against possible unwanted toxic effects.
