The issue of infertility stemming from the impact of food additives and enhancers on testicular toxicity has garnered significant attention. In response, herbal medicines are gaining prominence for their potential to counteract these detrimental effects on the testes, owing to the inherent chemical constituents within plants. This study aimed to assess the protective influence of Hemidesmus indicus ethanolic extract against alterations induced by Monosodium Glutamate (MSG) in rat testicular histology and the modulation of antioxidant markers.Twenty-four young adult Wistar male rats, aged 12 weeks, were subject to random allocation into four groups: the Control group (C), the MSG group (MSG), the Hemidesmus indicus ethanolic extract (HIE) group, and the combined Hemidesmus indicus ethanolic extract and MSG (HIE+MSG) group, each comprising six animals. The study extended over a 30-day period. Subsequent to the stipulated duration, the right testis underwent histological evaluation, while the left testis underwent assessment of antioxidant enzymatic activity. Rats exposed to MSG exhibited distinct morphological changes including arrested germ cell maturation, disruption of the basal lamina, cytoplasmic vacuolation, diminished germ cell development, including spermatids, and perturbations in testicular antioxidant levels. Encouragingly, the MSG+HIE treated group displayed a significant, progressive amelioration of these effects. This study underscores the potential of Hemidesmus indicus ethanolic extract as a protective agent against MSG-induced testicular alterations, warranting further investigation for its implications on testicular health and male fertility.
