Ethnobotanical knowledge of medicinal plants used in the treatment of male infertility in southern Benin

Infertility is a concern for couples, families and society. In almost half of the cases, it is due to male infertility. This infertility, in developing countries like Benin, often cured by the use of medicinal plants. This study aimed to enlist knowledge about medicinal plants used in the treatment of male infertility in southern Benin. An ethnomedicinal investigation has been conducted in southern Benin by questioning traditional healers and market herbalists using the method of semi-structured interview. Ethnopharmacological data has been analyzed by ethnobotanical indices such as informant consensus factor (ICF), frequency of citation for each plant species and contribution of each plant to drug recipes. 90 respondents including 36 market herbalists and 54 traditional healers participated in this study. Data collected allowed us to list 60 plant species belonging to 56 genera and 38 botanical families. Informants had a high degree of consensus (ICF = 0.58) on plants used for treatment of male infertility. The most plants cited by market herbalists wereGarcinia kola(10.09%),Cissus populnea(10.09%),Carpolobia lutea(07.40%) and the parts of plants most used were roots and fruits. For traditional healers,Garcinia kola(10.15%),Cyperus esculentus(06.09%),Citrus aurantiifiola(06.09%) were the most plants cited and parts of plants the most used were leaves and roots. This study provided a list of medicinal plants used for the treatment of male infertility in southern Benin. Further pharmacological and toxicological studies will assess the therapeutic efficacy of these medicinal plants.
