Potential activity of Aframomum daniellii (Zingiberaceae) dry seeds: A case study of its action mechanism on the Wistar rat strain with testicular deficiency.

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.

Guibourtia tessmannii-induced fictive ejaculation in spinal male rat: involvement of D, D-like receptors.

Context: Guibourtia tessmannii (Caesalpiniaceae) is a plant traditionally used as aphrodisiac. We previously reported the pro-ejaculatory effects of the aqueous and methanol extracts of G. tesmannii in spinal male rat.

Delay of ejaculation induced by Bersama engleriana in nicotinamide/streptozotocin-induced type 2 diabetic rats.

Objective: To evaluate the effects of aqueous and methanolic extracts of Bersama engleriana (B. engleriana) leaves on the expulsion phase of fictive ejaculation in nicotinamide/streptozotocin-induced type 2 diabetic male rats.

Methods: The electromyographic activity of the bulbospongiosus muscles was recorded in urethane anaesthetized, spinal cord transected rats receiving dopamine (0.
