UPLC-Q-TOF-MS profiling of Viola stocksii Boiss. and evaluation of aphrodisiac potential and risk factors associated with erectile dysfunction. JOURNAL OF ETHNOPHARMACOLOGY 2024; 321:117477. [PMID: 38007166 DOI: 10.1016/j.jep.2023.117477] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Revised: 11/13/2023] [Accepted: 11/15/2023] [Indexed: 11/27/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Viola stocksii Boiss. locally known as makhni or makhanr booti, is an important medicinal food plant with multiple therapeutic applications, including erectile dysfunction (ED). It is mixed with butter and used for boosting energy and sexual health in the subcontinent. AIMS OF THE STUDY This study was designed to evaluate the chemical composition, aphrodisiac potential and effect of V. stocksii on the risk factors associated with ED. METHODOLOGY The hydroethanolic extract of V. stocksii (HEEVS) was prepared through the microwave-assisted extraction (MAE) technique. The chemical composition was evaluated using preliminary phytochemical screening and UPLC-Q-TOF-MS analysis. Metals and minerals analysis was performed by an atomic absorption spectrophotometer. The aphrodisiac activity of HEEVS was evaluated using an in vivo aphrodisiac model established in male albino rats and the effect on various sexual parameters such as mount, intromission, ejaculation frequencies and mount, intromission, ejaculation latencies, postejaculatory interval, penile reflexes and serum hormone concentration were analyzed. The effect of HEEVS on various risk factors associated with ED, including prostate cancer (PC), bacterial infections, diabetes and obesity, was evaluated using various in vitro assays. Moreover, four compounds were selected from the UPLC-Q-TOF-MS profile and evaluated for in silico computational analysis against phosphodiesterase-5 (PDE-5) for possible interaction. FINDINGS The phytochemical screening revealed the presence of various secondary metabolites in HEEVS, while 58 compounds were tentatively identified in the UPLC-Q-TOF-MS analysis. Various important minerals and metals such as zinc, calcium, cadmium and magnesium were detected in the atomic absorption spectrometry analysis. The in vivo aphrodisiac evaluation showed a significant (p < 0.05) increase in the mount, intromission and ejaculation frequencies and a decrease in the mount, intromission latencies and post-ejaculatory intervals at a dose of 300 mg/kg. A marked (p < 0.05) increase was observed in the concentration of serum testosterone and luteinizing hormones in HEEVS treated animals with a significant increase in total penile reflexes. The extract displayed significant anti-prostate cancer activity and a potential antibacterial spectrum against E. coli and S. aureus, with MIC50 values of 215.72 μg/mL and 139.05 μg/mL, respectively. Similarly, HEEVS was found active towards pancreatic lipase (67.34 ± 1.03%), α-glucosidase (3.87 ± 0.54 mmol ACAE/g d.w.) and α-amylase (6.98 ± 1.63 mmol ACAE/g d.w.). The in silico docking study presented a potential interaction between the selected compounds and residues of the active site of PDE-5. CONCLUSION This report highlights the aphrodisiac potential of V. stocksii and provides experimental support for its traditional use in ED with an attenuative effect on the risk factors associated with ED. Moreover, the chemical composition displayed the presence of functional phytoconstituents and minerals in HEEVS and paves the way for the isolation of compounds with potent aphrodisiac activity.

The traditional use of native Brazilian plants for male sexual dysfunction: Evidence from ethnomedicinal applications, animal models, and possible mechanisms of action. JOURNAL OF ETHNOPHARMACOLOGY 2024; 318:116876. [PMID: 37437795 DOI: 10.1016/j.jep.2023.116876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 06/30/2023] [Accepted: 07/02/2023] [Indexed: 07/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Sexual dysfunction is a multifactorial health condition characterized by distressing disturbances in the sexual response and libido, leading to an inability to maintain penile erection and achieve pleasure. Considering the huge Brazilian biodiversity, many plants are traditionally used for aphrodisiac purposes. However, the use of native medicinal plants as sexual boosters in Brazil has been poorly studied. AIM OF THE STUDY This review focuses on the composition, pharmacology, and results of experimental trials of the main native plants used in Brazilian folk medicine with alleged aphrodisiac effects. We aimed to provide a state-of-the-art reference for research on herbs for the treatment of male sexual dysfunction by summarizing and discussing the main studies found. MATERIALS AND METHODS The relevant information was collected by searching keywords (aphrodisiac, sexual tonic, sexual stimulant, sexual vigor stimulant, sexual impotency, erectile dysfunction, etc.) from books containing primary surveys conducted in the original communities and bibliographic surveys prepared by authors linked to the national academic and scientific environment edited in Brazil. Preclinical and clinical studies of the compiled plant species were performed using scientific databases (Scopus, PubMed, SciELO, and SciFinder). RESULTS Seventy-four plant species belonging to 44 families used in Brazil to treat sexual dysfunction were compiled from ethnopharmacological literature. Fourteen plants, including Pfaffia glomerata (Spreng.) Pedersen, Aspidosperma quebracho-blanco Schltdl., Anemopaegma arvense (Vell.) Stellfeld ex de Souza, Mimosa pudica L., Heteropterys tomentosa A. Juss., Trichilia catigua A. Juss., and Turnera diffusa Willd. ex Schult. were pharmacologically studied to confirm these therapeutic properties. Probable modes of action include antioxidant and androgenic activities, inhibition of the PDE5 enzyme, increase in NO levels, and activation of dopaminergic and noradrenergic pathways. In addition, several different species popularly known as "catuaba" were identified, leading to adulterations and controversial effects. CONCLUSION The overall results of the present review of Brazilian folk literature reveal that Brazil has a long tradition of using plants with potential aphrodisiac effects. However, further research is required to identify, characterize, and standardize the active ingredients and herbal preparations used in aphrodisiacs.

Pharmacological insights on the antidepressant, anxiolytic and aphrodisiac potentials of Aglaonema hookerianum Schott. JOURNAL OF ETHNOPHARMACOLOGY 2021; 268:113664. [PMID: 33278545 DOI: 10.1016/j.jep.2020.113664] [Citation(s) in RCA: 65] [Impact Index Per Article: 21.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/23/2020] [Revised: 10/11/2020] [Accepted: 11/30/2020] [Indexed: 05/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Aglaonema hookerianum Schott is an ethnomedicinally important plant used to treat a variety of diseases, including sexual and depression-like disorders. However, the scientific basis underlying the aforesaid properties have not been well justified. AIM OF THE STUDY The present investigation aimed to investigate the anxiolytic, antidepressant and aphrodisiac potentials of methanol leaves extract of A. hookerianum (MEAH) in Swiss albino mice. MATERIALS & METHODS Swiss albino mice (20-30 g) were orally administrated with MEAH at the doses ranging from 100 to 400 mg/kg, b.w. The elevated plus maze (EPM) and hole board test (HBT) were performed to determine the anxiolytic activity and the forced swimming test (FST) and tail suspension test (TST) were performed to determine the antidepressant activity of MEAH. Besides, the aphrodisiac activity of MEAH was conducted through the mounting behaviour and orientation behaviour analysis. Diazepam (1 mg/kg, b.w., i.p.) for EPM and HBT; fluoxetine HCl (20 mg/kg, b.w., p.o.) for FST and TST, and sildenafil (5 mg/kg, b.w., p.o.) for the mounting behaviour analysis and orientation behaviour analysis were used as reference drugs. RESULTS The administration of the MEAH produced a strong (p < 0.001) dose-dependent anxiolytic effects in both HBT and EPM tests. Likewise, the extract revealed a significant (p < 0.001) reduction in the immobility time in both FST and TST as compared to the control group. Besides, the MEAH also found to possess marked aphrodisiac activity complying several facets such as an increase in the sexual performance at the highest dose (400 mg/kg, p.o.) as well as the orientation toward female mice (p < 0.001) at all tested doses. CONCLUSION Taken together, MEAH can be recommended as a potent source of neuroprotective and a libido-boosting drug candidate for the management of neurological and sexual disorders.

Abstract
INTRODUCTION Erectile dysfunction is the persistent or recurrent inability to achieve or maintain an erection sufficient for intercourse. Despite various treatment options, not all patients respond adequately and their usefulness is limited by adverse effects and cost. Botanical medicine and natural products have been and continue to be invaluable and untapped sources of new drugs, including potentially those to treat erectile dysfunction. OBJECTIVES To review the current literature on botanical medicine traditionally used as aphrodisiacs and treatment of erectile dysfunction, in particular, scientific and clinical investigations that have been performed, possible active phytoconstituents, and mechanisms of action and to identify gaps in current knowledge to better guide future research efforts. METHODS A comprehensive literature search was conducted via PubMed, Scopus, Science Direct, and Web of Science on English publications, using various keywords, for example, "herb", "natural product", combined with "erectile dysfunction", "aphrodisiac", and "sexual performance". RESULTS 369 relevant articles studying medicinal plants used for erectile dysfunction were analyzed. A total of 718 plants from 145 families and 499 genera were reported to be used traditionally as aphrodisiacs and treatment of erectile dysfunction. Top plants used include Pausinystalia johimbe, Lepidium meyenii, and Panax ginseng. Different plant parts are used, with roots being the most common. Less than half of these plants have been evaluated scientifically, using various research methodologies. Clinical trials conducted were collated. Current scientific investigation shows mixed results about their usefulness in enhancing sexual performance. A limited number of studies have attempted to elucidate the mechanisms of action of these medicinal plants. CONCLUSION A comprehensive literature review on botanical medicine and natural products used for treatment of erectile dysfunction was successfully conducted. Although medicinal plants serve as a potential source of lead compounds for erectile dysfunction drugs, further studies are warranted to further evaluate their efficacy and safety.

Medicinal plants/herbal supplements as female aphrodisiacs: Does any evidence exist to support their inclusion or potential in the treatment of FSD? JOURNAL OF ETHNOPHARMACOLOGY 2020; 251:112464. [PMID: 31881322 DOI: 10.1016/j.jep.2019.112464] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/19/2019] [Revised: 11/15/2019] [Accepted: 11/18/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Female Sexual Dysfunction is a complex condition with biopsychosocial origins. Plants traditionally used as aphrodisiacs may be promising as routes to develop therapeutic options which are lacking. AIM To distinguish the plants commonly used in (AP) on the market in the United States, and to evaluate their ethnobotanical and clinical evidence as a basis for their inclusion. METHODS This study is a narrative review of 53 species commonly found in AP on the market in the United States. Most species listed have anecdotal use as aphrodisiacs throughout history; therefore, a systematic search was done for clinical evidence. The primary outcome assessed is the clinical efficacy of plants in the treatment of libido desire disorders. RESULTS There is little to no evidence from the literature to substantiate claims of plants currently on the market as AP for female libido desire disorders. CONCLUSIONS The biggest problem in the literature is the lack of botanical verification and consistency in material across studies. Any botanical, commercial or otherwise must be tested for chemical markers exhibited by individual species; however, if no markers exist, work must first be done to determine these. Appropriate analytical techniques for this would include high pressure liquid chromatography, and mass spectroscopy. It would also be sufficient to taxonomically authenticate species provided the plant material. Further research should aim to standardize plant material and extraction methods utilized in order to compare studies effectively and allow for reproducibility to draw conclusions. While clear interest into investigation the aphrodisiac potential of plants exists, a translatable in vivo animal model does not. Clinical trials rely on patient reported outcomes to determine efficacy but cost and length of such trials deem a necessity for development of an animal model to first screen botanicals. We suggest development of screening tools utilizing the evident neurobiological underpinnings of FSD as the first step. In general, studies of plants currently used as ingredients for AP are severely lacking, and even so the evidence that exists is weak.

Pro-sexual and androgen enhancing effects of Tribulus terrestris L.: Fact or Fiction. JOURNAL OF ETHNOPHARMACOLOGY 2016; 179:345-355.

Abstract
ETHNO-PHARMACOLOGICAL RELEVANCE Historically, aphrodisiacs have had a reputation for making sex more achievable and satisfying. It has been long believed that Tribulus terrestris L. (TT), an annual plant of the family Zygophyllaceae, possesses aphrodisiac properties purportedly attributed to its ability to influence levels or mimic function of sex hormones. Due to this appealing beliefs, the popularity of medicinal products from TT is expanding at a remarkable pace among consumers who are attempting to enhance their sexual health. However, reliable scientific evidence supporting these purported bioactivities are scant and far from conclusive. AIM OF THE REVIEW To critically analyze and updated the evidence supporting a role for TT as an aphrodisiac and to reappraise the widely believed view of TT as an androgen enhancing botanical supplement. MATERIAL AND METHOD An extensive review of the literature was carried out based on systematic search of major scientific databases (PubMed, Elsevier, Springer Link, Google Scholar, Medline Plus, and Web of Science) for studies of phytochemical, pharmacological and traditional uses of TT published between 1968 and 2015. In addition, the reference lists of the available articles were reviewed and relevant studies including material in journals which are not indexed internationally were reviewed. RESULTS Analysis of phytochemical and pharmacological studies in humans and animals revealed an important role for TT in treating erectile dysfunction and sexual desire problems; however, empirical evidence to support the hypothesis that this desirable effects are due to androgen enhancing properties of TT is, at best, inconclusive, and analysis of empirical evidence from a comprehensive review of available literature proved this hypothesis wrong. While the mechanisms underlying TT aphrodisiac activity remain largely unknown, there is emerging compelling evidence from experimental studies in animals for possible endothelium and nitric oxide-dependent mechanisms underlying TT aphrodisiac and pro-erectile activities. CONCLUSION It is becoming increasingly clear that the deep-seated traditional view of TT bioactivity focused exclusively on its androgen enhancing properties is outdated and incapable for accommodating the emerging evidence from recent clinical and experimental studies pointing toward new and, perhaps, more plausible modes of action. Novel paradigms guiding the development of new testable hypotheses for TT aphrodisiac properties are needed to stimulate further investigations into potential biological mechanisms in which many apparently conflicting observations can be reconciled.

Abstract
BACKGROUND The phytochemical constituents of the aqueous root extract of Lecaniodiscus cupanioides Planch. Ex Bth. and its aphrodisiac activity on male rat sexual behavior and reproductive hormones in paroxetine-induced sexual dysfunction were evaluated. METHODS The extract was screened for the presence of phytochemicals. The extract (25, 50, and 100 mg/kg body weight) and the reference herbal drug PowmaxM (7.14 mg/kg body weight) were administered orally to paroxetine-induced sexually impaired male rats, once daily for 5 days, and their sexual behavior parameters were monitored and computed. The serum hormones (testosterone, follicle-stimulating hormone, and luteinizing hormone) were determined at the end of treatment period. RESULTS Phytochemical screening revealed the presence of alkaloids, anthraquinones, phenolics, saponins, and tannins. Mount frequency (MF), intromission frequency (IF), ejaculatory frequency (EF), and testosterone, follicle-stimulating hormone, and luteinizing hormone concentrations were reduced significantly (p<0.05) in paroxetine-treated rats. Administration of 25, 50, and 100 mg/kg body weight of the aqueous root extract of L. cupanioides significantly (p<0.05) reversed the paroxetine-mediated alterations in MF, IF, EF, mount latency (ML), intromission latency (IL), ejaculatory latency (EL), postejaculatory interval (PEI), and testosterone, follicle-stimulating hormone, and luteinizing hormone concentrations dose-dependently. The reversal of the male sexual behavior parameters by the extract compared well (p<0.05) with the PowmaxM-treated animals. CONCLUSIONS Data obtained from this study revealed that the aqueous root extract of L. cupanioides restored sexual competence in sexually impaired rats possibly by increasing sexual drive through enhanced reproductive hormones concentration, particularly testosterone, thus supporting the folkloric claim of the plant for the management of sexual disorder in males.

Abstract
The area of natural product research is rapidly progressing from traditional medicine to modern medicine having proper scientific basis of its usage. However, identifying the active constituent or the basis of its mechanism holds the key to synthesis of these drugs in the laboratory. Traditional Indian literature such as Ayurveda has listed several plant and animal based resources for treatment of almost every ailment. Erectile dysfunction and male sexual debilities are among the most explored areas in traditional medicine. A number of natural products, mostly plant based, have been claimed to cure erectile dysfunction and related male sexual debilities. These products often are aphrodisiac and have multi-fold effects on male reproductive system. This review aims at compiling the animal and plant based resources which bear promise of treating loss of libido and erectile dysfunction. A special emphasis is paid to find out scientific basis of their usage. The identification of potential resources could help undertake further studies to establish their possible mechanism of action; opening the doors to proper clinical trials for human use.

Abstract
An aphrodisiac is a type of food or drink that has the effect of making those who eat or drink it more aroused in a sexual way. Aphrodisiacs can be categorized according to their mode of action into three groups: substances that increase libido (i.e., sexual desire, arousal), substances that increase sexual potency (i.e., effectiveness of erection) and substances that increase sexual pleasure. Some well-known aphrodisiacs are Tribulus terrestrins, Withania somnifera, Eurycoma longifolia, Avena sativa, Ginko biloba, and Psoralea coryifolia. Ethnobotanical surveys have indicated a large number of plants as aphrodisiacs. The paper reviews the recent scientific validation on traditionally used herbal plants as aphrodisiac herbs for the management of sexual disorder erectile dysfunction.

Abstract
In the Veterinary Museum in Skara there is also an Animal Pharmacy. One bottle originating from the 18th century is labelled Tinct. Canthar. and thus contained an extract of Spanish flies. The active substance in such a tincture is cantharidin. The use and effects of this remedy in veterinary as well as human medicine are described. The use of cantharidin in the 18th century was linked to the predominant believe that illness was caused by imbalance of the four humours of the body. Its blistering effect was thought to "draw" superfluous liquid from the body. Its pronounced toxicity made its use to disappear, but it could still be found to be used in veterinary medicine as a blister and by undiscerning people as an aphrodisiac. Recent studies has shown cantharidin to possess antitumour effect--something that Dioscorides noted in his texts from around A.D. 40-80!

Abstract
AIM OF THE STUDY The root of Eurycoma longifolia Jack, native to South East Asia, has long been used as a male aphrodisiac remedy to treat sexual disorders. In the study we evaluated the influence of Eurycoma longifolia Jack on sexual behavior (including both motivation and copulatory performance) of sexually sluggish and impotent male rats. MATERIALS AND METHODS The root powder of the plant was orally administered to adult Sprague-Dawley male rats, classified as sexually sluggish or impotent taking in account their behavior in pre-experimental tests. Groups of 8 animals each were submitted to three different types of treatment: (1) acute at 3 dose levels (250, 500 and 1000 mg/kg); (2) subacute (daily for 6 days) at the dose of 500 mg/kg and (3) subchronic (daily for 12 days) at the same dose (500 mg/kg). Mount, intromission and ejaculation latencies and post-ejaculatory interval were recorded during the mating test in order to evaluate sexual performance. In addition the partner preference test was used to assess sexual motivation. Testosterone serum levels were measured in subacutely treated rats and compared with the values of controls receiving vehicle. RESULTS Concerning the copulatory activity of sexually sluggish rats, both acute (dosed at 500 and 1000 mg/kg) and subacute treatments with the root powder significantly reduced ejaculation latencies, increasing also the percentage of mounting and ejaculating animals; in addition the subacute administration reduced post-ejaculatory interval. In impotent rats both subacute and subchronic treatments increased the percentage of mounting and ejaculating rats. The motivational behavior of sluggish rats during the partner preference test was not affected by the treatments. Testosterone serum levels were increased in rats subacutely treated in comparison with controls. CONCLUSION Eurycoma longifolia root improved sexual performance but not motivation in sluggish rats after acute or subacute administration. The effect could be mainly ascribed to increased testosterone levels.

Abstract
In this study, the effect of Crocus sativus (saffron) was studied on male erectile dysfunction (ED). Twenty male patients with ED were followed for ten days in which each morning they took a tablet containing 200mg of saffron. Patients underwent the nocturnal penile tumescence (NPT) test and the international index of erectile function questionnaire (IIEF-15) at the start of the treatment and at the end of the ten days. After the ten days of taking saffron there was a statistically significant improvement in tip rigidity and tip tumescence as well as base rigidity and base tumescence. ILEF-15 total scores were significantly higher in patients after saffron treatment (before treatment 22.15+/-1.44; after treatment 39.20+/-1.90, p<0.001). Saffron showed a positive effect on sexual function with increased number and duration of erectile events seen in patients with ED even only after taking it for ten days.

Abstract
The rhizomes of Curculigo orchioides have been traditionally used as aphrodisiac. In the present study ethanolic extract of rhizomes was evaluated for its effect on sexual behavior in rats. Administration of 100 mg/kg of extract change significantly the sexual behavior as assessed by determining parameters such as penile erection, mating performance, mount frequency and mount latency. Moreover a pronounced anabolic and spermatogenic effect was evidenced by weight gains of reproductive organs. The treatment also markedly affected sexual behavior of animals as reflected in reduction of mount latency, an increase in mount frequency and enhanced attractability towards female. Penile erection index was also incremented in treated group.

Abstract
Fourteen commercial samples of the popular Brazilian aphrodisiac Catuaba specified as bark drugs of Anemopaegma, Erythroxylum and Trichilia species were examined for identity and purity. Only a minority of the examined Catuaba samples contained the crude drugs claimed on the labels. More than half of the products were adulterated with different crude drugs. The majority of the samples contained a bark originating from Trichilia catigua. The TLC fingerprints confirmed the heterogeneity, in 50% of the samples tropane alkaloids of various concentrations were detected. TLC and HPLC methods for separation and identification of the tropane alkaloids were developed and their analytical data (RF values, retention times, ESI-MS) given. The structure elucidation of the two main alkaloids, catuabine D and its hydroxymethyl derivative, is presented. The 1H- and 13C-NMR assignments of these alkaloids are discussed with regard to literature data. Neither aqueous nor methanolic extracts of the Trichilia catigua reference material nor alkaloid-enriched fractions of commercial samples showed any effect on the rabbit corpus cavernosum in an in vitro test.

Abstract
In the present study, the aphrodisiac activity of Butea frondonsa Koen. ex Roxb (Papillionaceae) bark extract was investigated. The extract (400 mg/kg body wt./day) was administered orally by gavage for 28 days. Mount latency (ML), intromission latency (IL), ejaculation latency (EL), mounting frequency (MF), intromission frequency (IF), ejaculation frequency (EF) and post-ejaculatory interval (PEI) were the parameters observed before and during the sexual behavior study at day 0, 7, 10, 14, 21, and 28. The extract reduced significantly ML, IL, EL and PEI (p < 0.05). The extract also increased significantly MF, IF and EF (p < 0.05). These effects were observed in sexually active and inactive male rats.

Abstract
The present work is a mini-review of the author's original work on the plant Passiflora incarnata Linn., which is used in several parts of the world as a traditional medicine for the management of anxiety, insomnia, epilepsy and morphine addiction. A tri-substituted benzoflavone moiety (BZF) has been isolated from the bioactive methanol extract of this plant, which has been proposed in the author's earlier work to be responsible for the biological activities of this plant. The BZF moiety has exhibited significantly encouraging results in the reversal of tolerance and dependence of several addiction-prone psychotropic drugs, including morphine, nicotine, ethanol, diazepam and delta-9-tetrahydrocannabinol, during earlier pharmacological studies conducted by the author. In addition to this, the BZF moiety has exhibited aphrodisiac, libido-enhancing and virility-enhancing properties in 2-year-old male rats. When administered concomitantly with nicotine, ethanol and delta-9-tetrahydrocannabinol for 30 days in male rats, the BZF also prevented the drug-induced decline in sexuality in male rats. Because the BZF moiety isolated from P. incarnata is a tri-substituted derivative of alpha-naphthoflavone (7,8-benzoflavone), a well-known aromatase-enzyme inhibitor, the mode of action of BZF has been postulated to be a neurosteroidal mechanism vide in which the BZF moiety prevents the metabolic degradation of testosterone and upregulates blood - testosterone levels in the body. As several flavonoids (e.g. chrysin, apigenin) and other phytoconstituents also possess aromatase-inhibiting properties, and the IC50 value of such phytomoieties is the main factor determining their biochemical efficacy, by altering their chemical structures to attain a desirable IC50 value new insights in medical therapeutics can be attained, keeping in view the menace of drug abuse worldwide.

Abstract
OBJECTIVE Apart from its claims for improvement of sexual functions in men, the puncturevine plant (Tribulus terrestris: TT) has long been considered as an energizer and vitalizer in the indigenous system of medicine. Sexual behavior and intracavernous pressure (ICP) measurements were taken in rats to scientifically validate the claim of TT [containing protodioscin (PTN)] as an aphrodisiac. MATERIALS AND METHODS Forty sexually mature male Sprague-Dawley rats were randomly divided into four groups of 10 each. Group I served as a control group and groups II, III, and IV were treated with three different doses of TT extract (2.5, 5 and 10 mg/kg body weight, respectively), orally, once daily for 8 weeks. Weight was recorded and the rats from all four groups were subjected to sexual behavior studies with primed females and various parameters namely mount and intromission frequencies (MF and IF, respectively), mount, intromission and ejaculation latencies (ML, IL, and EL, respectively) as well as postejaculatory interval (PEI) were recorded. In addition, blood pressure and ICP were recorded for all rats at the end of study. RESULTS Increases in body weight (by 9, 23, and 18% for groups II, III & IV) and ICP (by 43% and 26% for groups III and IV) were statistically significant compared to the control group. Increases in MF (by 27% and 24%) and IF (by 19% and 22%) for the groups III and IV were statistically significant. Decreases in ML (by 16%, 23%, and 22% for groups II, III, and IV) and PEI (by 20% for group III) were statistically significant compared to the control. CONCLUSIONS The weight gain and improvement in sexual behavior parameters observed in rats could be secondary to the androgen increasing property of TT (PTN) that was observed in our earlier study on primates. The increase in ICP which confirms the proerectile aphrodisiac property of TT could possibly be the result of an increase in androgen and subsequent release of nitric oxide from the nerve endings innervating the corpus cavernosum.

Abstract
The aphrodisiac properties of the methanol extract of leaves of Passiflora incarnata Linn. have been evaluated in mice by observing the mounting behaviour. The methanol extract of P. incarnata exhibited significant aphrodisiac behaviour in male mice at all doses, i.e. 75, 100 and 150 mg/kg. Amongst these, the highest activity was observed with the 100 mg/kg dose when the mountings were calculated about 95 min after the administration of the test extracts.

Abstract
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.

Abstract
Authors survey the conservative treatment possibilities of erectile dysfunction. With the increase in interest, they estimate the new oral- and intracavernosal drugs, giving a review of their experiences with the treatment. A perspective prognosis is given of the important role of NO (nitric oxide) donors and PHD (phosphodiesterase) inhibitor drugs in the field of conservative therapy, while intracavernosal and intraurethral prostaglandin therapies are still important ingredients in the therapeutic arsenal, as is hormone substitution in indicated cases.

Abstract
Modern pharmacological treatment of impotence is determined by the presenting symptoms. Since this involves symptomatology with a heterogenous aetiology, many different drugs are involved in the treatment of impotence. Drugs used for libido and arousal problems include testosterone, yohimbine, trazodone and apomorphine. Since patient self-assessment is the only parameter that can be used to measure the result of treatment and positive results are seldom affirmed, no positive benefit of these agents can be assumed at present. Oral medications for erectile dysfunction include yohimbine, trazodone, apomorphine, phentolamine, arginine and sildenafil. Of these drugs, sildenafil has been the most systematically studied for effectiveness, but long term safety data await the results of post-marketing surveillance. Of the ejaculation disorder therapies, treatments for premature ejaculation are the best studied. Favourable results have been obtained with clomipramine, paroxetine and fluoxetine. The safety of these medications has been assessed through their long term use in psychiatry. Intracavernous self-injections for erectile disorders are performed using a variety of drugs and drug mixtures. Only alprostadil and the combination of papaverine with phentolamine are widely used. Alprostadil is very well tolerated; however, penile pain is a serious problem in a significant proportion of patients. Papaverine in combination with phentolamine is effective, but penile fibrosis and priapism occur more often than with the use of alprostadil. Several new developments in this area are currently under way. Alternative routes for medication for erectile dysfunction include ointments and patches to the penile skin and the glans. Only transurethral alprostadil, 'MUSE' (medicated urethral system for erection) has been shown to be effective in large trials. Long term safety still has to be demonstrated, but the 1-year safety profile is encouraging. In general, the end points of impotence treatment studies are very diverse so efficacy data can only be assessed in comparative studies. However, long term comparison studies have not been performed. Safety demands must be set very high for this type of treatment since the disorders being treated present no threat to the patient's health.

Abstract
A commercial product, Libido (Libid, Libbido, Erosom and Ardorare, names used in different markets), which is based on components derived from fertilized, partly incubated chickens' eggs, has been used to treat diminished sexual desire in men. The results from two double-blind cross-over placebo-controlled experiments indicate that Libido has a significant enhancing effect on sexual desire in men with normal and reduced sexual drive. Over periods as short as 2 weeks, 58% of the participants with low sexual desire noticed improvement as assessed using a visual analogue scale. Data obtained from consumers suggest significant effects on the frequency of sexual intercourse, on increased self-esteem, on the level of happiness, and on stamina. In a separate Swedish study, 84% of 31 men reported increased sexual desire during 3 weeks on Libido. It takes 1-2 weeks of regular use of Libido (3 g twice daily) before noticeable changes are observed.

Abstract
In the present study, a large-scale retrospective case review was undertaken to assess the incidence and type of sexual dysfunctions associated with serotonin reuptake inhibitor (SRI) therapy, in addition to the effects of three pharmacological antidotes (yohimbine, amantadine, cyproheptadine) on SRI-induced sexual dysfunctions. A retrospective chart review was conducted on 596 patients treated with SRIs in an outpatient psychiatric practice between July 1991 and September 1994. Patients who reported new-onset sexual dysfunction during this time were categorized as having SRI-induced sexual dysfunctions. Sexual difficulties were characterized by type and duration, and the background characteristics and psychiatric diagnoses of all patients were recorded. Psychiatric outcome and sexual functioning at follow-up were independently assessed by a single psychiatrist by means of a 4-point rating scale. Sexual dysfunction symptoms were clearly associated with SRI administration in 97 (16.3%) cases. The most common problems reported were orgasmic delay or anorgasmia and hypoactive sexual desire. Sexual difficulties were more frequent among men (23.4%) and married patients of both sexes (22.3%), whereas psychiatric diagnosis and type of SRI were unrelated to the occurrence of sexual problems. Of the patients with sexual dysfunction, 45 (46.4%) opted for a trial of antidote therapy with yohimbine, amantadine, or cyproheptadine. All three antidotes were found to be safe and relatively effective, although yohimbine was significantly more effective than amantadine or cyproheptadine in reversing SRI-induced sexual dysfunction.

Abstract
Erectile dysfunction has an organic etiology in most cases, with vascular disease the single most common cause. In addition to a thorough history and physical examination, clinical evaluation may include hormonal assessment, diabetes screening, nocturnal tumescence testing and color Doppler flow studies of the penile vasculature. Therapy for erectile dysfunction has progressed rapidly during the past decade, with alternatives including hormone supplements, vacuum constriction devices, penile self-injection therapy and penile prostheses. The majority of patients and their partners report satisfactory results with these treatments.

Abstract
The search for an effective aphrodisiac has been a perennial pursuit of most societies throughout history. In the past decade, attention has focused increasingly on the prosexual effects of oral pharmacological agents with central neurotransmitter actions. The role of various dopaminergic, adrenergic, and serotonergic agents, in particular, has been intensively investigated in both human and animal studies. Some of these drugs have been considered for their potential role in the treatment of sexual dysfunction, while others have contributed to our understanding of basic neurophysiological processes in sexual arousal. This review provides a critical evaluation of current laboratory and clinical research on the "new aphrodisiacs," including studies in both patient populations and normal volunteers. Several conceptual and methodological problems are addressed, such as the definition and measurement of sexual response, the need to separate specific and nonspecific drug effects on sexual response, and the lack of studies in women. Although no single drug has proven to be clinically safe and reliably effective for human use, several promising candidates have been identified. Overall, research on prosexual drugs has contributed significantly to our understanding of basic mechanisms in sexual response, as well as providing new treatment options for common sexual disorders.

Abstract
The sexual function in man can be modified decreasing brain serotonin by PCPA and increasing brain cathecolamines by monoamineoxidase inhibitors. In 5 volunteers, sexual deficient men, the combination of PCPA with phenelzine (IMAO) stressed an increase in sexual stimulation, measured by number of erections. In two subjects this effect lasted for 2 months. A clear improvement in mood has also been shown. This pharmacological combination opens new and interesting possibilities in sexual deficiency treatment.
