Abstract

Aim: To evaluate the aphrodisiac potential of Terminalia catappa Linn. seeds using a suspension of its kernel (SS) in 1% methyl cellulose in rats. Methods: Male rats were orally treated with 1500 mg/kg or 3000 mg/kg SS or vehicle, and their sexual behaviour was monitored 3 h later using a receptive female. Another group of rats was orally treated with either 3000 mg/kg SS or vehicle for 7 consecutive days. Their sexual behaviour and fertility were evaluated on days 1, 4 and 7 of treatment and day 7 post-treatment by pairing overnight with a pro-oestrous female. Results: The 1500 mg/kg dose, had a marked aphrodisiac action (prolongation of ejaculation latency) but no effect on libido (% mounting, % intromission and % ejaculation), sexual vigour (mounting-and-intromission frequency), or sexual performance (intercopulatory interval). In contrast, the higher dose (3000 mg/kg) reversibly inhibited all the parameters of sexual behaviour other than mounting-and-intromission frequency and copulatory efficiency. The effects of high dose SS were not due to general toxicity, liver toxicity, haemotoxicity, stress, muscle deficiency, muscle incoordination, analgesia, hypoglycaemia or reduction in blood testosterone level. They were due to marked sedation. Conclusion: The kernel of T. catappa seeds has aphrodisiac activity and may be useful in the treatment of certain forms of sexual inadequacies, such as premature ejaculation.

ABSTRACT

Sexual dysfunction, that is the repeated inability to achieve normal sexual intercourse, which include various forms like premature ejaculation, retrograded, retarded or inhibited ejaculation, erectile dysfunction, arousal difficulties (reduced libido), compulsive sexual behaviour, orgasmic disorder and failure of detumesence, are on the increase world wide because of aging population and other increasing etiological factors. Several management options employed are associated with some serious side effects not readily available and are expensive. The search for natural supplement from medicinal plants is being intensified probably, because of its reduced side effect, its ready availability and reduced cost. Therefore, the increasing search for medicinal plants with aphrodisiac potentials has necessitated the need to review methods available for screening medicinal plants with aphrodisiac potentials in males.
