Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Data from the Massachusetts Male Aging Study (MMAS), a community based, random sample prospective observational survey of non-institutionalized men aged 40-70years, found that 52% of men reported erectile dysfunction. ED is commonly classified into three categories based on its etiology. These include organic, psychogenic and mixed ED. However, this classification should be used with caution since most cases are actually of mixed etiology. It is therefore suggested to use the term primary organic or primary psychogenic. Phosphodiesterase type 5 inhibitors are the standard care and treatment for most mild to moderate ED patients. Most common side effects of phosphodiesterase-5 inhibitors are in the form of headache, visual abnormalities, nasal congestion, dyspepsia, and myalgia.
Enhancing healthy sexuality is possible with the use of natural plants and nutrients. In Asia, men consider herbal medicine to be a reliable treatment for improving overall wellbeing, including sexual wellbeing.
In Malaysia the root of Eurycoma longifolia, known traditionally as Tongkat Ali, is one of the most popular herbs used for well-being. It is used to increase fertility and sexual power and is claimed to improve strength and power during sexual activities. Many studies carried out on rats and mice have found that administration of E. longifolia extracts increases the sexual arousal and motivation and frequency of sexual activity. These effects are similar to those caused by administration of testosterone, although the effect of Tongkat Ali is not as strong. Tongkat Ali is reputed to increase testosterone effect. It was found to have androgenic effects in male rats, either directly or indirectly, such as increasing the weight of sexual accessories. The effect of this plant is dependent upon the dose; whether or not it contributes significantly to the aphrodisiac qualities of Tongkat ali can only be established with more research.
A recent systematic review with meta-analysis concluded that the herbal extract of Tongkat Ali may have clinical effect on erectile function. However, more efficacy trials are warranted to further support current evidence.
Maca (Lepidium meyenii) is an Andean plant that belongs to the brasslike (mustard) family. It has been used for centuries in enhancing the fertility in humans and animals. Preparations from the Maca root have been reported to improve sexual function in healthy populations. There is a hypothesis questioning if Maca is effective in improving sexual function. Spermatogenic and fertility-enhancing activities are suggested through animal experiments. Some in-vivo studies have shown that Maca may improve sexual behavior and enhance androgen-like effects in rats. Recent clinical trials have also suggested significant effects of Maca for increasing sperm count and mobility and improving sexual function in humans.
However, these data are insufficient for determining whether Maca is clinically effective.
The results of a recent systematic review provide suggestive evidence for the effectiveness of Maca in improving semen quality.
By today, robust clinical data on Tongka tali and Maca safety and efficacy is not sufficient. This study was conducted to evaluate Efficacy and Safety of Tongkat Ali Maca Plus for the improvement of sexual well-being and quality of life in men with mild to moderate erectile dysfunction.
