Effects of Aframomum melegueta and Piper guineense on sexual behaviour of male rats

Abstract

The effects of aqueous extracts of Aframomum melegueta and Piper guineense on the sexual behaviour of male rats were studied, considering many criteria, such as penile erection, copulatory behaviour and orientation activities towards themselves (genital grooming) and female rats (ano-genital sniffing, mounting). For 8 days different groups of rats received a daily administration of distilled water (control) or a plant extract: A. melegueta at 115 mg/kg or P. guineense at 122.5 mg/kg. Both plant extracts stimulated male sexual behaviour. In fact, A. melegueta and P. guineense significantly increased penile erection index, and the frequencies of intromission and ejaculation. These plant extracts were found to enhance the orientation of males towards females by increasing mounting and ano-genital investigatory behaviour. Results of this study showed that A. melegueta and P. guineense modified the sexual behaviour of male rats by increasing sexual arousal.

Rise of Herbal and Traditional Medicine in Erectile Dysfunction Management

“…Kamtchouing et al [43] reported that oral administration of P. guineense fruit aqueous extract increased penile erection index in male rats compared to controls. By using orchidectomized rat models, androgens have been proven to be essential for normal penile erection [44][45][46].…”

“…Fadogia agrestis (Rubiaceae) is commonly used to treat ED in Nigeria [43]. Yakubu et al [72] reported that mounting frequency and intromission frequency increased in a dosedependent manner, while mounting latency and intromission latency decreased with increasing dose and treatment duration in treated male rats compared to control after oral administration of F. agrestis stem aqueous extract.…”

Aphrodisiacs from plant and animal sources—A review of current scientific literature

“…Aframomum melegueta (Guinea pepper) is a spice from the ginger family obtained from the seeds of the plant. It has been shown to increase rat sexual behavior and improve penile erection (Kamtchouing et al, 2002). The dried fruit of Piper guineense (West African Pepper) has also been shown to have the same properties as determined in the same study by Kamtchouing.…”

Aphrodisiac properties of some Zimbabwean medicinal plants formulations

“…In Africa, several plants such as M. whitei, E. capensis, aloe and pumpkin seed have been used for many years to improve sexual stimulation and improvement of sexual performance (Kamtchouing et al, 2002;Orisakwe et al, 2004). However, few experimental studies have been performed in order to define these claims of efficacy (Lampiao et al, 2008).…”
