Date (Phoenix dactylifera L. Mill) fruit enhances sexual performance via modulation of oxido-inflammatory mediators and purinergic signaling in hypertensive male rats.

INTRODUCTION: The present study aimed at investigating the effect of dietary supplementation of Phoenix dactylifera, an important component of aphrodisiac supplements, on sexual performance, oxido-inflammatory mediators and purinergic signaling system in hypertensive rats. MATERIAL AND METHODS: Hypertension was induced via oral administration of 40 mg/kg L-NAME. Thereafter, the sexual performance of the experimental animals was determined and the hypertensive rats with impaired sexual activities were placed on P. dactylifera-supplemented diet for 21 days, and the effects of the treatment on the overall sexual behavior, antioxidant status, oxido-inflammatory biomarkers, and enzyme activity of the purinergic system were assessed. RESULTS: Hypertensive rats showed a significant (p < 0.05) decrease in sexual performance, elevated level of oxido-inflammatory mediators, and altered purinergic enzymes activity when compared with the control. However, sub-chronic feeding with P. dactylifera-supplemented diet improved sexual performance, significantly lowered oxido-inflammatory biomarkers, and enhanced the activity of purinergic enzymes in hypertensive rats. CONCLUSION: Findings presented in this study suggest that dietary inclusion of P. dactylifera could be useful in managing erectile dysfunction (ED) commonly observed in subjects with hypertension. Findings highlighted in this study thus provide the scientific basis supporting the folkloric use of P. dactylifera as a key ingredient in aphrodisiac supplements.

Efficacy and Safety of Common Ingredients in Aphrodisiacs Used for Erectile Dysfunction: A Review.

INTRODUCTION: Erectile dysfunction (ED) is the inability to attain or sustain an erection for sexual intercourse. Affected men endorse difficulties with intimacy and feelings of guilt and shame. Although medical treatments are available, patients are reluctant to discuss ED with physicians and often use dietary supplements to attempt to treat their ED. As such, there is a need to better understand the effects of ingredients used in nutraceuticals for ED treatment. OBJECTIVES: To summarize the literature on the efficacy and safety of the most common ingredients used in ED supplements. METHODS: 10 of the most common ingredients in ED supplements were reviewed using PubMed-indexed literature to assess their efficacy and safety in treating ED. Key findings were summarized to include historical use, active ingredients, prior animal studies, human studies, and toxicity. RESULTS: Nutraceuticals used in ED treatment include a variety of ingredients. Although L-arginine is a safe supplement with clinical data supporting improved erectile function, limited data exist on the efficacy of other ingredients in the treatment of ED. CONCLUSION: Despite the growing use of supplements for treatment of sexual dysfunction, ED supplements remain poorly studied, with limited data demonstrating efficacy of individual ingredients. Further study is required to definitively determine the efficacy of nutraceuticals in ED treatment. Srivatsav A, Balasubramanian A, Pathak UI, et al.

The Impact of Illicit Use of Amphetamine on Male Sexual Functions.

INTRODUCTION: Data concerning the impact of amphetamine on male sexual functions are limited, although amphetamine has been used as an aphrodisiac. AIMS: This cross-sectional study was to assess the impact of illicit use of amphetamine on male sexual functions. METHODS: Male illicit drug users in a Drug Abstention and Treatment Center were recruited to complete a self-administered questionnaire, and data were compared with age-matched controls. MAIN OUTCOME MEASURES: The International Index of Erectile Function (IIEF) and global assessment questions were used to assess sexual functions. RESULTS: Of 1,159 amphetamine mono-illicit drug users, the mean age was 31.9 ± 7.5 (18-57) years, and mean duration of drug use was 30.7 ± 52.2 (median 9, range 0.1-252) months. Half of them reported that drug use had no impact on their sexual functions. The other half reported drug impacts as reduced erectile rigidity and sexual life satisfaction, enhanced orgasmic intensity, and prolonged ejaculation latency time more often than the opposite effects, while they reported enhanced or reduced effect equally on sexual desire. Dosing frequency of amphetamine was associated with its impact on sexual functions, but duration of its use had little association with that. Compared with 211 age-matched controls, the amphetamine mono-illicit drug users had lower IIEF scores in the domains of erectile function, orgasmic function, and overall satisfaction, but there are no significant differences in intercourse satisfaction and sexual desire scores. The prevalence of erectile dysfunction (ED) was significantly higher in the drug users than in the controls (29.3% vs. 11.9%). The odds ratio of ED for amphetamine use was 2.1 (95% confidence interval 1.2-3.6) after adjustment for other risk factors. CONCLUSIONS: The impact of illicit use of amphetamine on male sexual functions varied among users, and their ED prevalence was higher than the controls.

Black stone - a natural remedy for premature ejaculation and performance enhancement, or maybe not?

We describe the use of a non-prescribed aid (Black stone) for premature ejaculation that resulted in a chemical burn on the penis with an appearance similar to severe balanitis.

Natural aphrodisiacs.

INTRODUCTION: The search for a remedy or a prescription that can enhance sexual function and/or treat male erectile dysfunction has been an obsession throughout known history. Whether it was an Eastern civilization or a Western one, religious or atheist, man's aspiration for a better or best "manhood" has been a history-time goal. AIM: This review will discuss the current research done on the most popular natural aphrodisiacs and examine the weight of evidence to support or discourage the use of any of these substances to enhance sexual desire and/or function. METHODS: Review of the current evidence on the use of natural substances as aphrodisiacs. MAIN OUTCOME MEASURES: Efficacy of natural aphrodisiacs in enhancing sexual function in men and women. RESULTS: There is little evidence from literature to recommend the usage of natural aphrodisiacs for the enhancement of sexual desire and/or performance. Data on yohimbine's efficacy does not support the wide use of the drug, which has only mild effects in the treatment of psychogenic ED. Although there's a positive trend towards recommending ginseng as an effective aphrodisiac, however, more in depth studies involving large number of subjects and its mechanism of action are needed before definite conclusions could be reached. Data on the use of natural aphrodisiacs in women is limited. CONCLUSIONS: The current body of objective evidence does not support the use of any natural aphrodisiac as an effective treatment for male or female sexual dysfunctions. Potent men and men with ED will continue the search for natural aphrodisiacs despite the current disappointing data on their effectiveness. Care should be taken regarding the fraud addition of sildenafil analogues to natural aphrodisiacs.

Dose- and time-dependent effects of ethanolic extract of Mucuna pruriens Linn. seed on sexual behaviour of normal male rats.

AIM OF THE STUDY: According to Indian Systems of Medicine, Mucuna pruriens Linn., belonging to the leguminous family (Papilionaceae), were used for treating male sexual disorders since ancient times. In this study, the effects of ethanolic extracts of the Mucuna pruriens Linn. seed on general mating behaviour, libido and potency of normal male Wister albino rats were investigated and also compared with the standard reference drug, Sildenafil citrate. MATERIALS AND METHODS: Animals were divided into one control group (Group I--received saline) and four experimental groups (Groups II-V). Experimental groups were divided on the basis of the dosage of extract to the animals as follows: 150 mg/kg body weight (Group I), 200mg/kg body weight (Group II) and 250 mg/kg body weight (Group IV) while Group V received Sildenafil citrate (5mg/kg body weight). Animals were fed PO with saline or extract or standard drug once in a day for 45 days. To analyse the mating behaviour, female rats with oestrus phase were used. RESULTS: The extract administered PO significantly increased the mounting frequency, intromission frequency and ejaculation latency, and decreased the mounting latency, intromission latency, post-ejaculatory interval and inter-intromission interval. The potency test significantly increased erections, quick flips, long flips and total reflex. Therefore, the results indicated that the ethanolic extracts of Mucuna pruriens Linn. seed produced a significant and sustained increase in the sexual activity of normal male rats at a particular dose (200mg/kg). When compared to control, all the drug-treated groups have shown drug-induced effects for a few parameters. However in Group II, there was an obvious enhancement in all parameters, without affecting the normal behaviour. When compared with the standard drug, the net effect of extract is even less than that in Group II. CONCLUSIONS: Therefore, the resulting aphrodisiac activity of the extract lends support to the claim that it has traditionally been used for the treatment of sexual disorders.

Bandaged penis.

This is a case of a male in his late 30s who died due to acute myocardial ischemia. His penis was bandaged. The penis was inflamed and had infected abrasions. The possible relevances of such an incidental finding and its contribution to sudden death is explored. The case report shows photographs of the bandage in situ and its components, inflammation of frenulum, injury to the shaft, and the generalized inflamed and mildly swollen penis. These changes were considered to be caused by bites. The micro-photographic findings in the case were of acute myocardial ischemia, pulmonary oedema, and fatty liver.

Aphrodisiac drug-induced hemolysis.

Volatile alkyl nitrites have been used during the past decades for "recreational purposes," and for intensifying sexual experience. Their use has been associated with methemoglobinemia and hemolysis. We report three patients who presented over the past year with acute hemolysis after inhalation of butyl nitrite, two of them had glucose-6-phosphate dehydrogenase (G6PD) deficiency.

The aphrodisiac and adaptogenic properties of ginseng.

Ginseng is the root of the perennial herbs of Panax quinquefolium and Panax ginseng which contain a series of tetracyclic triterpenoid saponins (ginsenosides) as active ingredients. It is considered a tonic or adaptogenic that enhances physical performance (including sexual), promotes vitality and increases resistance to stress and ageing. The adaptogenic properties of ginseng are believed to be due to its effects on hypothalamic-pituitary-adrenal axis, resulting in elevated plasma corticotropin and corticosteroids levels. When used appropriately, ginseng appears to be safe. Nevertheless, documented side effects include hypertension, diarrhoea, restlessness, mastalgia and vaginal bleeding.

A case of methemoglobinemia after ingestion of an aphrodisiac, later proven as dapsone.

Methemoglobin (MetHb) is an oxidation product of hemoglobin in which the sixth coordination position of ferric iron is bound to a water molecule or to a hydroxyl group. The most common cause of acquired MetHb-emia is accidental poisoning which usually is the result of ingestion of water containing nitrates or food containing nitrite, and sometimes the inhalation or ingestion of butyl or amyl nitrite used as an aphrodisiac. We herein report a case of MetHb-emia after ingestion of an aphrodisiac, later identified as dapsone by gas chromatograph/mass selective detector (GC/MSD). A 24-year old male was admitted due to cyanosis after ingestion of a drug purchased as an aphrodisiac. On arterial blood gas analysis, pH was 7.32, PaCO2 26.8 mmHg, PaO2 75.6 mmHg, and bicarbonate 13.9 mmol/L. Initial pulse oxymetry was 89%. With 3 liter of nasal oxygen supplement, oxygen saturation was increased to 90-92%, but cyanosis did not disappear. Despite continuous supplement of oxygen, cyanosis was not improved. On the fifth hospital day, MetHb was 24.9%. Methylene blue was administered (2 mg/kg intravenously) and the patient rapidly improved. We proved the composition of aphrodisiac as dapsone by the method of GC/MSD.
