RESUMO
This work was undertaken to evaluate the biological activity of the aqueous extract of the dry seeds of Aframomum daniellii seeds on the copulatory performance of rats with testicular deficiency. Hypogonadal adult male rats (30) were divided into 6 groups: group I received distilled water (10 ml/kg), group II received sildenafil citrate (5 mg/kg), group III received intramuscular injections of testosterone enanthate (3. 6 mg/kg), group IV, V, and VI received the aqueous extract of A. daniellii at the respective doses of 100, 200, and 400 mg/kg/po/day for 14 days. The copulatory performance of the animals were assessed on days 1, 7 and 14 through the following copulation parameters: Mount, intromission, and ejaculation latency (ML, IL, and EL) and frequency (MF, IF and EF), average interval of copulation (AIC) and post-ejaculatory interval (PEI)). We noticed a significant decrease of ML (p < 0.05), IL (p < 0.01), EL (p < 0.001) and the increase of MF, IF and EF (p < 0.01) particularly at doses of 100 and 400 mg/kg when compared to group I and II. In addition, we noticed a significant increase of AIC from day 7 (p < 0.05) to day 14 (p < 0.001) at the same two doses while the PEI significantly decreased from the 1st (p < 0.01) to the 14th day (p < 0.001) when compared to group I and II. These findings demonstrated that A. daniellii aqueous extract of seeds enhanced pro-sexual potential and pro-sexual desire in male rats with testicular deficiency.
