Dose-Dependent Effects

Occimim gratissimum, a plant with a history of traditional medicinal use, has gained attention for its reported anti-inflammatory, antimicrobial, and antioxidant properties. However, its effects on the male reproductive system, in particularly on testosterone levels and testicular histology, remain largely unexplored. This study employed a controlled
experimental design using male Wistar rats divided into four groups: Control, Low Dose, Medium Dose, and High Dose, receiving different dosages of Occimim gratissimum leaf extract. Testosterone levels were measured, and testicular histology was examined using hematoxylin and eosin (H&E) staining. In the Low Dose group (100 mg/kg), a significant decrease in testosterone levels was observed (Mean ± SD = 0.2617 ± 0.09 ng/ml), accompanied by increased Leydig cell population and active interstitial congestion. The Medium Dose group (300 mg/kg) showed no significant changes in testosterone levels (Mean ± SD = 1.142 ± 0.525 ng/ml) but exhibited similar Leydig cell responses and interstitial congestion. The High
Dose group (500 mg/kg) displayed no major disruptions in testosterone levels (Mean ± SD = 0.3887 ± 0.109 ng/ml)
or testicular histology. The results suggest that Occimim gratissimum leaf extract may have dose-dependent effects on
testosterone production and Leydig cell populations. However, the extract did not severely disrupt the spermatogenic process or testicular tissue. Further research is needed to elucidate the mechanisms behind these changes and their implications for male reproductive health
