This study investigated effect of p-coumaric acid (PCA) on erectogenic enzyme activity and non-protein thiol level in the penile tissue of normal and doxorubicin (DOX)-induced oxidative stress male rat. Sixty-four (64) adult male rats weighing between 170 and 180 g were used for this work. After 14 days of acclimatisation, the rats were divided into eight groups (n = 8). Rats were orally pre-treated with PCA dose dependently (50 and 100 mg/kg body weight [b.w.t]) and vitamin E (100 mg/kg b.w.t) for 14 days before induction with a single dose of DOX (15 mg/kg b.w.t, via i.p.). The result revealed that arginase, acetylcholinesterase (AChE), angiotensin-I-converting enzyme (ACE), phosphodiesterase-5 (PDE-5), adenosine monophosphohydrolase (AMPdase) activities were significantly (p < 0.05) higher in the DOX-induced rats as against the control, which was significantly p < 0.05) higher when compared to normal rats treated with PCA. PCA also improved non-protein thiol level in the penile tissue of both normal and DOX-induced rats. Hence, this study revealed that PCA is capable of causing inhibitory effects on the activities of enzymes, associated with oxidative stress-induced erectile dysfunction (ED) and could also be used as an aphrodisiac agent in the management/treatment of ED.
