UNLABELLED: The use of medicinal plants in the management of several ailments is gaining popularity nowadays. Massularia acuminata, one of such plants is commonly used as chewing sticks due to its antimicrobial activity and the aqueous extract of its stem as an aphrodisiac. Aphrodisiac activity in some plants may be due to androgen increasing property of its phytochemicals.

AIM OF THE STUDY: This study therefore sought to assess the androgenic potentials of aqueous extract of Massularia acuminata stem in male rats for 21 days.

MATERIALS AND METHODS: Male rats weighing between 220 and 260 g were completely randomized into four groups: A, B, C and D. Group A, the control received orally 1 ml of distilled water (the vehicle) while groups B, C and D were orally administered with 1 ml each corresponding to 250, 500 and 1000 mg/kg body weight of the plant extract, respectively for 21 days. Rats were sacrificed 24h after 1, 7 and 21 days.

RESULTS: Compared with the control, extract administration at all the doses produced significant increase (P<0.05) in testes-body weight ratio, testicular protein, glycogen, sialic acid, cholesterol, testosterone, luteinizing and follicle stimulating hormone concentrations throughout the period of administration. Testicular gamma glutamyl transferase activities were decreased significantly (P<0.05) after the first dose and was sustained throughout the experimental period.

CONCLUSION: The available evidence in this study suggests that aqueous extract of Massularia acuminata stem has androgenic potential which may stimulate male sexual maturation and enhance normal testicular function.
