Pharmacological profiling of Argemone mexicana for its aphrodisiac potentials in male Wistar rats

Abstract Objective To study the aphrodisiac potentials of ethanol extract of Argemone mexicana L. ( A. mexicana ) of Papaveraceae family in sexually sluggish male Wistar rats. Methods The sexually inactive male rats were divided into two groups of 8 rats each. The test group animals were treated with ethanol extract of A. mexicana (EEAM) at 1 g/kg daily oral dose for 28 days. Other group animals were treated with sildenafil citrate at an oral dose of 5 mg/kg. The latencies of mount, intromission, ejaculation; post ejaculatory pause and frequencies of mount, intromission, and ejaculation were measured on 0, 7th, 14th, 21st and 28th days. Serum testosterone levels were estimated using ELISA. Results The EEAM was nonlethal even at dose of 4.0 g/kg. The oral dosing of EEAM has significantly enhanced the orientation of males towards female by increase in ano-genital investigatory behavior, frequencies of mount, intromission, and ejaculation ( P P P Conclusion The EEAM has elevated sexual dysfunctions in male rats. These potentials may be related to protopine alkaloids and flavanols by means of physiological stimulus for penile vasculature. Thus, results support the use of EEAM in enhancing sexual behavior in sluggish male rats.
