Dioscorea species are dioecious, in which, the male and female plants produce their underground tubers. Dioscorea spp. is renowned for secondary metabolites production and widely used in the pharmaceutical industry and medicine. Dioscorea spp. capitulates fifty percent of the total steroid drugs worldwide. Enormous literature concerning the morphology, medicinal potentiality, secondary metabolite, and bioactivities of Dioscorea spp. are available without denoting the sexes of Dioscorea. This present study aims for sexual dimorphism analysis through micromorphology, secondary metabolite content, antioxidant, and antimicrobial activities analysis. Male and female mature tubers of Dioscorea species were collected from the forest floor of Tripura and used to assess secondary metabolite, antioxidant and antimicrobial activity. For the micromorphological study, mature tubers were planted in the experimental garden and observed micromorphological differences among the male and female plants of Dioscorea species. The results of this study exhibits substantial variation between male and female plants. The tubers of the female plants are superior in acquiring phytoconstituents and possess superior antimicrobial and antioxidant potentiality compared to their male counterparts. This study may provide an effective, influential contribution to the modern scientific communities concerning the extraction of the biologically active constituents from these dioecious tubers, which may untie a new horizon in the pharmaceutical industries.
