E longifolia is a medicinal plant (family Simaroubaceae) native to Indonesia, Malaysia, Thailand, Vietnam and Laos. The root extract has been found to be the most powerful herbal aphrodisiac [17]. Tongkat ali extracts contain many alkaloids, quassinoids, phenolic compounds, tannins, high-molecular-weight glycoproteins and mucopolysaccharides. The main bioactive compounds are eurycomaoside, eurycolactone, eurycomalactone, eurycomanone and pasakbumin-B. It is considered to be natural ‘Viagra’. It increases sexual desire, and enhances performance and general well-being [17- 19]. In addition to its aphrodisiac effect, other medicinal effects, such as antimalarial, antibacterial, antipyretic, antiulcer and antitumour effects, have been reported [20,21]. Root decoction has been used as a general tonic (18,22]. Laboratory animal studies show that root extract enhances sexual characteristics and performance in rodents [22-25]. In a study involving a boar model, it was found that E longifolia root extract-treated boars increased sperm counts and semen volume; the effect was attributed to increased level of plasma testosterone [26]. Reports also suggest that E longifolia extract reverses the inhibitory effects of estrogen on testosterone production and spermatogenesis in rats [27]. Oral administration of E longifolia extract to inexperienced castrated male rats produced dose-dependent increases in sexual performance [28]. Zakaria et al [29] found that eurycomanone, a potential bioactive compound in the root extract of E longifolia, induced apoptosis in hepatocarcinoma (Hep G2) cells. Furthermore, their work suggested that eurycomanone was cytotoxic to Hep G2 cells and less toxic to normal Chang’s liver and WLR-68 cells. Tambi and Imran [19] investigated the effects of water-soluble extract of the root of E longifolia Jack and found that the extract increased semen volume, sperm concentration, percent of normal sperm morphology and sperm motility in male partners of subfertile couples with idiopathic infertility. Supplementation with E longifolia elevated the testosterone levels and upregulated osteoprotegerin gene expression in male Sprague-Dawley rats [30].

There have been some studies to suggest that a placebo effect that improves ED may work for some men. One study found that men taking an oral placebo pill showed as much improvement in ED symptoms as men who took actual medication to improve ED. Conversely, men who were given therapeutic suggestions to improve ED did not see signs of symptom improvement.
There’s no bedroom bummer quite like having to fly at half mast, but your penis problems are likely more common than you think: As many as 30 million American men suffer from erectile dysfunction, and one in four who seek treatment for ED are actually under the age of 40, according to a study in The Journal of Sexual Medicine. We all know there’s a little blue pill that can fix the failure to launch—but you don’t necessarily have to fill a ‘script to save your stiffy.
Animal testicles: derived from bulls and wild boars, the orchic substance has been used as a way to possibly increase testosterone levels and sperm counts. In Singapore, testis soap was once very popular (Figure 2). It is still sold in parts of China and Japan. The dried Dog testis and penis (canis familiaris) is believed to tonify the kidneys and strengthen the yang II. Kidney deficiency is believed to be the cause of impotency in Chinese literature.
Reproductive Health care is the second most prevalent health care problem on African continent4. Reproductive health care did not appear on the health agenda until recent after the Cairo conference on population and the Peking conference on women that it indeed became a live issue4. In some instances RH certainly includes the RH needs of the youth or adolescents.
Tongkat Ali (Eurycoma longiflora) (Figure 7): this native plant found through SE Asia is used as an Aphrodisiac since 1996 (5). It has to be used regularly and works by enhancing the testosterone and cGMP production. Benefits are felt gradually over a period of time, mainly because it enhances the natural biological synthesis of testosterone. When the level is increased, health and vitality are restored. In studies on Mice, Tongkat Ali increases the number of times and duration of sexual performance of the animals under study (8) with testosterone levels increasing up to 440% in some animals. In a recent study on humans, 62% of subjects showed an increase of the free testosterone index indicating it’s biostimulatory effect on steroidogenesis. It has also been shown to increase sperm concentration and motility and increases energy in the individual by enhancing ATP production by 60% thru oxidative phosphorylation.
Antioxidants  boost nitric oxide production and prevent NO breakdown. Ascorbic acid has direct effects on the bioactivity of NO, and augments NO production in a variety of body processes. The effects are actually synergistic with Vitamin E. Both vitamins are not usually measured, and a reasonable dose of Vitamin C is 500 to 1,000 mg daily. Vitamin E supplementation should be limited to <400 IU per day because of potential adverse long-term health effects of higher doses.
A combination of yohimbine and L-arginine is shown to significantly improve erectile function in people with ED. L-arginine is an amino acid that helps expand blood vessels. It’s regarded as safe and effective for ED but can cause side effects like nausea, diarrhea, and stomach cramps. Avoid taking L-arginine with Viagra, nitrates, or any high blood pressure medications.
