Abstract
This work aimed to evaluate the effects of the aqueous extract of Vepris afzelii roots on a rat model of hypogonadism. Phytochemical screening and acute toxicity of the extract were performed using different procedures. Hypogonadism was induced orally in adult Wistar rats using cyproterone acetate (30 mg/kg) for ten days. Besides six normal rats (10 ml/kg of distilled water, normal control), 30 hypogonadal rats were subdivided into five groups of six animals each, receiving for 14 days: distilled water (10 ml/kg, hypogonadal control), testosterone (4 mg/kg/3days) and the extract of V. afzelii (100, 200 and 400 mg/kg). Sexual behavior, sperm parameters, testes function and structure were assessed. Compared to the normal controls, significant (p = 0.0000) increases in mount (24 ± 0.94 seconds vs. 1200 ± 00 seconds) and intromission (49.16 ± 10.85 seconds vs. 1200 ± 00 seconds) latencies, and post-ejaculatory interval (381.72 ± 37.55 seconds vs. 1200 ± 00 seconds) were observed in all groups receiving cyproterone acetate on day 0. Total inhibitions of mounts (63.50 ± 8.91 vs. 00 ± 00), intromissions (36.66 ± 3.51 vs. 00 ± 00) (p = 0.0000), ejaculations (2.83 ± 00 vs. 00 ± 00, p = 0.0002) frequencies and mean copulatory interval (627.30 ± 81.80 vs. 00 ± 00, p = 0.0000) were also observed in these groups. Moreover, decreases in daily sperm production (2.65 ± 0.19 vs. 1.17 ± 0.08, p = 0.0498), percentage of sperm mobility (78.64 ± 8.41 vs. 10.12 ± 2.32), serum testosterone level (8.39 ± 0.63 ng/dl vs. 1.68 ± 0.19 ng/dl), diameter of seminiferous tubules (111.97 ± 0.51 µm vs. 94.51 ± 0.57 µm) and height of germinal epithelium (46.58 ± 0.34 µm vs. 33.74 ± 0.66 µm) (p = 0.0000) associated with increases in sperm transit (3.13 ± 0.45 vs. 11.07 ± 1.45, p = 0.0000) were also observed in these groups. Interestingly, compared to hypogonadal control and day 0, the administration of V. afzelii extract induced significant (p = 0.0000) improvements in all these altered parameters with 400 mg/kg being the most active dose. These results, attributed to saponins, flavonoids, polyphenols and triterpenes detected in this plant's extract confirm its traditional usage and could be useful for the management of patients suffering from hypogonadism.

Abstract
Infertility is a significant cause of anxiety, depression, and social stigma among couples and families. In such cases, male reproductive factors contribute widely to the extent of 20-70%. Male infertility is a multifactorial disease with several complications contributing to its diagnosis. Although its management encompasses both modern and traditional medicine arenas, the first line of treatment, adopted by most males, focuses on the reasonably successful medicinal plant-based conventional therapies. Phyto-therapeutics, which relies on active ingredients from traditionally known herbs, influences sexual behavior and male fertility factors. The potency of these phyto-actives depends on their preparation methods and forms of consumption, including decoctions, extracts, semi-purified compounds, etc., as inferred from in vitro and in vivo (laboratory animal models and human) studies. The mechanisms of action therein involve the testosterone pathway for stimulation of spermatogenesis, reduction of oxidative stress, inhibition of inflammation, activation of signaling pathways in the testes [extracellular-regulated kinase (ERK)/protein kinase B(PKB)/transformation of growth factor-beta 1(TGF-β1)/nuclear factor kappa-light-chain-enhancer of activated B cells NF-kB signaling pathways] and mediation of sexual behavior. This review critically focuses on the medicinal plants and their potent actives, along with the biochemical and molecular mechanisms that modulate vital pathways associated with the successful management of male infertility. Such intrinsic knowledge will significantly further studies on medicinal plants that improve male reproductive health.

Abstract
Erectile dysfunction (ED) is one of the main challenges occurring among men worldwide, and is characterised by trouble getting or keeping steady erection during sexual intercourse. Various drugs like sildenafil, a phosphodiesterase-5 inhibitor (PDE-5) are freely available in the pharmacies, though normally associated with several adverse. This study was designed to assess the molecular relations obtainable between catechin, garcinal, garcinoic acid and d-tocotrienol compounds isolated from Garcinia kola and targeted receptor linked to ED. These processes include the molecular docking of catechin, garcinal, garcinoic acid, d-tocotrienol, and sildenafil to receptor: PDE-5 via AutoDock Vina. Following the docking of catechin, garcinal, garcinoic acid and d-tocotrienol with the PDE-5-receptor protein, we observed that all are protein inhibitors with garcinoic acid showing better binding affinity -10.0 kcal/mol with PDE-5 receptor relevant to ED. Hence, the results provided insights into the development of garcinoic acid as a replacement for present ED management, with further analysis worth considering.

Acute effect of an infusion of Montanoa tomentosa on despair-like behavior and activation of oxytocin hypothalamic cells in Wistar rats. J Tradit Complement Med 2020; 10:45-51. [PMID: 31956557 PMCID: PMC6957806 DOI: 10.1016/j.jtcme.2019.01.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2018] [Revised: 11/28/2018] [Accepted: 01/29/2019] [Indexed: 11/30/2022] Open
Abstract
Background and aim In Mexican traditional medicine, Montanoa tomentosa (Mt) has been used as a remedy for reproductive impairments and mood swings. In pre-clinical research, both the extract and some of its active metabolites have produced oxytocinergic-like effects on female reproductive organs; however, there are no detailed studies of its effects on mood swing and brain structures. The aim of this study, was to analyze the behavioral effects of acute administration of a Mt infusion on male rats, during the Open Field (OFT) and Forced Swim (FST) Tests, and their association with the activation of oxytocin (OXT) cells, indicated by Fos protein (Fos/OXT) in the paraventricular (PVN) and supraoptic nuclei (SON). Experimental procedure 52 adult male Wistar rats were assigned to two conditions; with FST (n = 8), or without (n = 5). Each integrated condition included four groups [Control, Vehicle, Fluoxetine (Flx; 10 mg/kg), and Mt (50 mg/kg), p.o.]. Results and conclusion Mt and Flx treatment produced an anti-despair-like effect on the FST, but no significant changes in locomotor activity. Also, the Mt infusion -but not Flx-significantly increased the number of Fos/OXT cells in the PVN and SON, regardless of the condition, compared to the control and vehicle groups. These results show that Mt, but not Flx, produces an anti-despair-like effect that could be associated with the activation of OXT cells in PVN and SON. This study thus contributes to our knowledge of the pharmacological activity of Mt infusions, which could be a natural antidepressant agent with future clinical relevance.

Abstract
Background We investigated the effects of a polyherbal formulation prepared from the extracts of Mondia whitei (Periplocaceae), Dracaena arborea (Dracaenaceae), and Bridelia ferruginea (Euphorbiaceae) (MDB) on the sexual behavior of normal rats (NR) and prediabetic rats (PR). Methods Male Wistar rats were administered with drinking fructose solution (21%) or tap water for 16 weeks. After induction of prediabetic status, NR (n = 30) and PR (n = 30) were randomly distributed into 10 groups of six animals each and orally treated with distilled water (10 mL/kg), sildenafil citrate (5 mg/kg), or MDB (50, 100, or 500 mg/kg) for 21 days. Sexual behavior parameters per series (S) of ejaculation were evaluated on days 1, 7, 14, and 21. Results Drinking fructose solution (21%) induced prediabetic status in rats, characterized by a significant (p < 0.01) increase in glycemia by 43.41% compared with the control group. MDB improved sexual performances of NR and PR by increasing the mount frequency (MF) and the intromission frequency (IF) as well as the number of rats capable of ejaculating. For instance, the MF and the IF were significantly increased in animals administered with MDB for 7 (50 mg/kg, S1 and S2), 14 (100 mg/kg, S3), or 21 days (100 or 500 mg/kg, S2). This increase was more pronounced on days 7 and 14 in NR and PR treated with sildenafil citrate or MDB extracts, respectively. Conclusions The mixture of MDB improved sexual activity in NR and PR. This result may further justify the traditional use of these plants as sexual performance enhancers.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Novel therapeutic opportunities from medicinal agents continue to arouse scientific interest in recent times. Still, there is a dearth of information as regards experimental evidence generated from medicinal plants that would yield pharmacological agents for the treatment of erectile dysfunction. Acridocarpus Smeathmannii (DC.) Guill. & Perr. Root (ASR) has a long history as an aphrodisiac in African traditional medicine. Thus, this study investigated the reproductive potentials and associated biochemical mechanisms of its hydroethanolic extract (HEASR) in male Wistar rats. Also, the bioactive compounds were identified. MATERIALS AND METHODS Fifty-four male albino rats (180 ± 20 g) were divided into nine groups of six rats/group. Control, group 1 received normal saline (10 mL/kg). Groups 2-6 rats were administered sildenafil (1.43 mg/kg/day), mesterolone (0.36 mg/kg/day), doxazocin (0.03 mg/kg/day), HEASR1 (50 mg/kg/day) and HEASR2 (200 mg/kg/day) respectively. Others received co-administration of HEASR2 with standard drugs. Treatment lasted for 28 days via oral gavage. RESULTS An acute oral toxicity of HEASR up to 2 g/kg produced no mortality in mice p.o. while the median lethal dose was estimated to be 810 mg/kg i.p. HEASR2 administration or in combination with sildenafil, mesterolone and doxazocin increased mounting frequencies on day 28 by 77.44%, 122.65%, 148.5% and 93.88% and sperm counts by 38.29%, 55.21%, 42.48%, and 48.98% respectively in treated rats. HEASR2 + sildenafil elevated testosterone and follicle stimulating hormone levels by 36.33% and 24.55% while HEASR2 + doxazocin elevated luteinizing hormone levels by 97.44% in rats. HEASR modulated prostate-specific antigen and malondialdehyde levels respectively. Reduced glutathione, superoxide dismutase, and catalase activities were raised in five selected organs. Serum nitric oxide but not cyclooxygenase-2 or tumor necrosis factor-α levels was moderately improved in rats. CONCLUSION Overall, the results obtained demonstrated the potential of HEASR as a male reproductive enhancer, thus justify its folklore applications. Further, octadecanoic acid ethyl ester was the most abundant bioactive component present.

Abstract
Nauclea latifolia is used in traditional medicine for the treatment of male reproductive diseases. Despite its vast uses, its effects on the male reproductive system have not been scientifically proven. This study aimed to investigate the effects of Nauclea latifolia root decoction on sexual behavior and functions in male rabbits. Twenty-four male rabbits were divided into four groups: The first group received daily distilled water orally. The second, third, and fourth groups were orally treated with 100, 200, and 400 mg/kg body weight of Nuclea latifolia root, respectively. Sexual behavior parameters were carried out on weeks 1, 2, and 3 of the study. Testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were measured from the serum, while the testes tissue samples were used for antioxidant and histopathological examinations. Treatment with 200 and 400 mg/kg body weight resulted in significantly (p < .05) increased frequencies of mounting and intromission. In addition, the ejaculation latency was significantly prolonged (p < .05). The latencies of mounting and intromission were significantly decreased (p < .05), whereas ejaculation frequency increased. Serum testosterone, FSH, and LH increased significantly (p < .05) after treatment with Nuclea latifolia. There was an increase in epididymal sperm counts at 200 and 400 mg/kg body weight doses compared to the control. The extract also increased sperm motility and viability and improved testicular oxidative status. Histological examination revealed an increase in germinal layer thickness. The present study suggests that treatment with N. latifolia improves male sexual function and fertility and protects the testes from oxidative damage.

Abstract
The effects of aqueous extract of Brysocarpus coccineus roots (AEBCR) were studied on sexual behaviour and testicular function of paroxetine-induced sexual dysfunction (SD) in male rats. Ninety, sexually matured male rats (150.88 ± 5.53 g) were assigned into two groups: A and B. Fifteen SD animals from group B were each allotted to B1, B2, B3, B4 and B5 and received distilled water (DW), Powmax M (7.14 mg/kg body weight, b.w.) 50, 100 and 150 mg/kg b.w of AEBCR, respectively, for 7 days while the non-SD animals (group A) received DW. Eleven secondary metabolites were present in AEBCR. The lowered (p < .05) ejaculation frequency, penile erection index and penile grooming, higher mount and intromission frequencies, prolonged (p < .05) latencies of mount, intromission, ejaculation, and post-ejaculatory interval, reduced (p < .05) serum luteinising hormone, follicle stimulating hormone, testosterone, nitric oxide and testicular function indices, degenerated seminiferous tubules and low luminal spermatozoa contents by paroxetine were significantly (p < .05) attenuated and/or reinstated by AEBCR and Powmax M. The restoration of androgen-dependent sexual and testicular functions in SD male rats by AEBCR validates its folkloric use as aphrodisiac. Clinical studies are desirable to ascertain the efficacy of AEBCR in SD.

Abstract
BACKGROUND Montanoa frutescens and Montanoa grandiflora have been indistinctly used for centuries in traditional Mexican medicine for reproductive impairments, anxiety, and mood disorders. Preclinical studies support their aphrodisiac and anxiolytic properties, but their effects on mood are still unexplored. METHODS The effects of 25 and 50 mg/kg of M frutescens and M grandiflora extracts were evaluated on days 1, 7, 14, 21, and 28 of treatment, and compared with fluoxetine (1 mg/kg) and Remotiv (7.14 mg/kg) in Wistar rats. The participation of GABAA receptor in the effects produced by the treatments was explored. RESULTS Montanoa extracts reduced immobility since day 1 of treatment, while fluoxetine and Remotiv required 14 days. The GABAA antagonism blocked the effects of Montanoa extracts, but not of fluoxetine or Remotiv. CONCLUSIONS Montanoa extracts prevented quickly the stress-induced behaviors in the swimming test through action at the GABAA receptor, exerting a protective effect different to the typical antidepressants drugs.

Abstract
In the present study, the aphrodisiac properties of the purple corn (Zea mays) in male rats were analyzed. The aqueous crude extract of purple corn (at 25, 50, and 75 mg/kg) was administered to (a) copulating male rats and (b) anesthetized and spinal cord transected male rats. Behavioral parameters of copulatory behavior and parameters of the genital motor pattern of ejaculation previous to its inhibition, under the influence of the purple corn extract, are described. Administration of the aqueous crude extract of purple corn significantly facilitates the arousal and execution of male rat sexual behavior without significant influences on the ambulatory behavior. In addition, purple corn extract elicit a significant increase in the number of discharges of the ejaculatory motor patterns and in the total number of genital motor patterns evoked in spinal rats. The present findings show that the aqueous crude extract of purple corn possesses aphrodisiac activity.

Abstract
BACKGROUND Phlegmariurus saururus is popularly known in Argentina as aphrodisiac. For this reason, it was previously investigated and determined that the decoction of this plant elicits pro-ejaculatory activity and increases the ejaculatory potency in the Fictive Ejaculation Model. HYPOTHESIS/PURPOSE: the decoction of P. saururus facilitates sexual behavior in sexually experienced male rat and induces copulatory behavior in non-copulating male rats. METHODS The extraction method (decoction) was validated through Selectivity, Accuracy and Precision, by identification of the majority alkaloids, expressed as sauroxine. Male (sexually experienced and noncopulating) and female (receptive) Wistar rats were used to determine sexual behavior. Sildenafil was used as positive control. The following variables were evaluated: Mount Latency, Intromission Latency, Ejaculation Latency, Post Ejaculatory Interval, as well as the Mounts and Intromissions Number. RESULTS In sexually experienced male rats, P. saururus decoction stimulates sexual arousal and facilitates sexual execution. In noncopulating male rats, this decoction induces copulation with behavioral characteristics similar to sexually experienced animals. CONCLUSION P. saururus possesses aphrodisiac activity in copulating and noncopulating male rats.

Abstract
Objective. We studied prosexual effects of Eremomastax speciosa aqueous extract in male adult rats. Materials and Methods. 100 and 500 mg/kg of extract were administered orally (days 0, 1, 4, 7, 14, and 28 (posttreatment)). The sexual behavior of rats receiving a single dose (500 mg/kg) was also evaluated after pretreatment with Lω-NAME (10 mg/kg), haloperidol (1 mg/kg), or atropine (5 mg/kg). Controls received distilled water or testosterone enanthate (20 mg/kg/day/3 days (s.c.) before the test). Results. The extract (days 1–14) had no significant effect on mount, intromission, and ejaculation frequencies but on day 28 (14 days after treatment), it increased frequency of mounts and intromissions at 500 mg/kg. Mount, intromission, and ejaculation latencies reduced and postejaculatory intervals decreased but the effect did not persist 2 weeks after treatment. Extract prosex effects were greatly reduced by atropine and completely abolished by haloperidol, while Lω-NAME increased mount latency and potentiated extract effect on intromission and ejaculation latencies. Conclusion. In summary, E. speciosa extract can have positive effects on male sexual motivation and performance when administered for two weeks at the dose of 500 mg/kg. The effects (dopaminergic and/or cholinergic dependent) tend to appear during the posttreatment period.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Montanoa tomentosa also named Cihuapatli is a native plant of Mexico that has been used in traditional medicine for the last five centuries mainly as a remedy for reproductive impairments. However, there are reports indicating that this plant was also consumed by Mexican ancient people for its relaxing properties. In order to corroborate this information, the present study was conducted to evaluate the effect of Montanoa tomentosa lyophilisate (MT) on rat׳s anxiety-like behavior and to analyze its mechanism of action. MATERIALS AND METHODS The anxiolytic-like action of MT (1.5, 3.0, 6.0 and 12.0 mg/kg) was investigated in male Wistar rats tested in three animal models of anxiety: the burying behavior, the elevated plus maze and the hole-board tests. As a positive control, the anti-anxiety effects of different doses of the selective GABAA receptor agonist muscimol were also analyzed. In order to evaluate the participation of the GABAA and oxytocin receptors in the anxiolytic-like actions of MT, the GABAA receptors blockers picrotoxin (0.25 and 0.50 mg/kg), bicuculline (2.0 mg/kg) and flumazenil (5.00 and 10.0 mg/kg), the neurosteroid inhibitor finasteride (50.0 and 100 mg/kg) and the oxytocin receptor antagonist atosiban (0.25 µg) were used. Finally, to evaluate general activity, and motor coordination, the open field and rota-rod tests were used. RESULTS MT at 3.0 mg/kg showed anxiolytic-like effects in the three anxiety paradigms without affecting reactivity, general motor activity or motor coordination; however, at higher doses sedative effects were observed. Picrotoxin (0.25 and 0.50 mg/kg), flumazenil (10.0 mg/kg) and finasteride (100 mg/kg) antagonized the anxiolytic-like actions of MT in the burying behavior test. In the plus maze and hole-board tests bicuculline (2.0 mg/kg) blocked the effects of the plant as well. Atosiban (0.25 µg) did not antagonize the anxiolytic-like actions of MT. CONCLUSIONS The results corroborate the anxiolytic-like actions of Montanoa tomentosa and suggest that this effect is mediated through GABAA receptors but not oxytocin receptors.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Huperzia saururus (Lam.) Trevis. has an extensive ethnopharmacological use, mainly because of its aphrodisiac properties. The species is consumed as decoctions or infusions in traditional medicine. The purpose of the present research was to determine if Huperzia saururus is able to increase sexual potency by evaluating the ejaculatory response, in the presence of a decoction in spinal cord transected male rats. MATERIALS AND METHODS The fictive ejaculation model to record the rhythmic contractions of the bulbospongiosus muscles that accompany ejaculation as an indicator of ejaculation occurrence was used. Sexually experienced male Wistar rats were used. The activation of the fictive ejaculation by the i.v. administration of a decoction was tested, as well as the effects of the oxytocinergic, cholinergic, adrenergic and nitrergic antagonism upon the pro-ejaculatory activity of Huperzia saururus. RESULTS Decoction (3µg/animal) was able to activate the fictive ejaculation in spinal male rats, producing a statistically significant diminution on the latency of discharge parameter and a statistically significant augment for the number of discharges. Moreover, when sequential treatments using antagonists plus decoction were administered, the effects produced showed that prazosin prevent the pro-ejaculatory effect of the decoction and that the four antagonists assayed blocked the facilitatory effect of Huperzia saururus since the facilitation in the latency of response was prevented, and the number of discharges was reduced. Together these findings support the notion that the decoction exerts an aphrodisiac effect influencing the ejaculatory potency which is partially mediated by oxytocinergic, cholinergic, adrenergic and nitrergic spinal mechanisms. CONCLUSION In agreement to the ethnopharmacological uses, Huperzia saururus decoction has aphrodisiac properties by influence on the ejaculatory potency.

Abstract
The use of plant or plant-based products to stimulate sexual desire and to enhance performance and enjoyment is almost as old as the human race itself. The present paper reviews the active, natural principles, and crude extracts of plants, which have been useful in sexual disorders, have potential for improving sexual behaviour and performance, and are helpful in spermatogenesis and reproduction. Review of refereed journals and scientific literature available in electronic databases and traditional literature available in India was extensively performed. The work reviews correlation of the evidence with traditional claims, elucidation, and evaluation of a plausible concept governing the usage of plants as aphrodisiac in total. Phytoconstituents with known structures have been classified in appropriate chemical groups and the active crude extracts have been tabulated. Data on their pharmacological activity, mechanism of action, and toxicity are reported. The present review provides an overview of the herbs and their active molecule with claims for improvement of sexual behaviour. A number of herbal drugs have been validated for their effect on sexual behavior and fertility and can therefore serve as basis for the identification of new chemical leads useful in sexual and erectile dysfunction.

Abstract
Objective: To investigate the aphrodisiac potential of polyherbal formulations prepared from different parts of Tribulus terrestris, Curculigo orchioides, Allium tuberosum, Cucurbita pepo, Elephant creeper, Mucuna pruriens, and Terminalia catappa in Albino rats in specified ratio as suspension. Materials and Methods: The different concentrations of prepared polyherbal formulations i.e. 150, 300, and 600 mg/kg and sildenafil citrate as standard (5 mg/kg) and vehicle (control) were administered orally to rats (n = 6 animals per group) for 3 weeks. Mating behavior parameters in male rats was monitored in first week and third week week of treatment pairing with receptive females. After termination of drug treatment, the mating performance, hormonal analysis, sperm count, and testes-body weight ratio were also evaluated. Results: The polyherbal formulation showed a significant increase in mating behavior as well as mating performance, serum hormonal levels, sperm count, and testes-body weight ratio with dose-dependent relationship as compared to vehicle control. But the dose of 600 mg/kg of polyherbal formulation assumes closer resemblance of above parameters with the standard used. Conclusion: The results of the study strongly suggest that the polyherbal formulations have a good aphrodisiac activity on rats in the above experimental models, which may be an alternative weapon for various sexual dysfunctions in future.

Abstract
In previous studies, the anxiolytic-like effects of Montanoa tomentosa and Montanoa frutescens were reported in male rats, but the potential anxiolytic-like effects of Montanoa plants during the different phases of the ovarian cycle in rats remain to be explored. The anxiolytic-like effects of the aqueous crude extracts of M. frutescens (25 and 50 mg/kg) and M. grandiflora (25 and 50 mg/kg) in the elevated plus maze were investigated in Wistar rats during the estrous cycle and compared with 2 mg/kg diazepam as a reference anxiolytic drug. To investigate any motor effect (i.e., hyperactivity, no changes, or hypoactivity) associated with the treatments, the rats were evaluated in the open field test. The M. frutescens (25 and 50 mg/kg) and M. grandiflora (50 mg/kg) extracts exerted anxiolytic-like effects during the metestrus-diestrus phase, similar to diazepam, without disrupting spontaneous motor activity. No significant effects of the extracts were detected in either behavioral test during the proestrus-estrus phase, whereas diazepam produced motor hypoactivity in the open field test. These results indicate that the M. frutescens and M. grandiflora extracts possess anxiolytic-like effects that depend on the ovarian cycle phase, supporting the Mexican ancient medicinal use of these plants to ameliorate anxiety disorders.

Abstract
In the present study, evidence on the aphrodisiac activity of Montanoa frutescens and Montanoa grandiflora and a comparison with the aphrodisiac activity of Montanoa tomentosa is presented. By using the fictive ejaculation model in spinal male rats, electromyographic recordings of the genital motor pattern of ejaculation were obtained in the bulbospongiosus muscles and analyzed after the intravenous injection of aqueous crude extracts of Montanoa tomentosa, Montanoa frutescens, and Montanoa grandiflora. Results showed that the systemic administration of the aqueous crude extracts of Montanoa plants elicits a significant increase in the ejaculatory capacity of spinal male rats with very robust ejaculatory motor patterns that included the expression of tonic penile erections and penile movements and the potent expulsion of urethral contents. In conclusion, Montanoa frutescens and Montanoa grandiflora increase the ejaculatory potency with aphrodisiac activity similar to Montanoa tomentosa.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Turnera diffusa Wild has been used in folk medicine by its aphrodisiac and tranquilizing properties. Previously we experimentally showed the aphrodisiac effect of a chemically characterized aqueous extract of Turnera diffusa in male rats. However, the mechanism of action underlying such effects has not been studied. STUDY AIMS As part of our systematic studies of pharmacological properties of Turnera diffusa, we aimed to analyze whether the increased sexual motivation and the augmented sexual performance of sexually sluggish (SL) male rats treated with Turnera diffusa involves the NO pathway. Additionally we analyzed whether such effects were exerted at the level of the brain or the spinal cord. Finally, anxiety levels and ambulatory activity were also evaluated. MATERIAL AND METHODS Turnera diffusa (10-40 mg/kg) and sildenafil citrate (10 mg/kg) with or without a nonspecific inhibitor of NO synthase, Nω-nitro-L-arginine methyl esther (L-NAME, 12.5 mg/kg) were evaluated in SL rats, in a standard sexual behavior test and in the fictive ejaculation model in spinal cord transected and urethane-anaesthetized SL rats. Anxiety levels or ambulation were assessed in the burying behavior and open-field tests. RESULTS Turnera diffusa and sildenafil (both at 10 mg/kg) facilitated expression of male sexual behavior by shortening mainly ejaculation latency. Treatments also facilitated the number of discharges in the ejaculatory motor pattern as well as the number of ejaculatory motor patterns and its associated penile erections. L-NAME prevented the pro-sexual effects of treatments on both experimental models. Besides, the extract of Turnera diffusa (10 mg/kg) produced an anxiolytic-like effect in male rats without affecting ambulation. CONCLUSIONS Findings from the present work support the notion that pro-sexual effect of the aqueous extract of Turnera diffusa in rats involves the participation of NO pathway, mainly at central level. The anxiolytic-like effect of Turnera diffusa is an advantage to its use for improving sexual performance.

Mondia whitei (Periplocaceae) prevents and Guibourtia tessmannii (Caesalpiniaceae) facilitates fictive ejaculation in spinal male rats. Altern Ther Health Med 2013; 13:4. [PMID: 23295154 PMCID: PMC3544574 DOI: 10.1186/1472-6882-13-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2012] [Accepted: 01/04/2013] [Indexed: 01/11/2023]
Abstract
Background Mondia whitei and Guibourtia tessmannii are used in Cameroon traditional medicine as aphrodisiacs. The present study was undertaken to evaluate the pro-ejaculatory effects of the aqueous and organic solvent extracts of these plants in spinal male rats. Methods In spinal cord transected and urethane-anesthetized rats, two electrodes where inserted into the bulbospongiosus muscles and the ejaculatory motor pattern was recorded on a polygraph after urethral and penile stimulations, intravenous injection of saline (0.1 ml/100 g), dopamine (0.1 μM/kg), aqueous and organic solvent plant extracts (20 mg/kg). Results In all spinal rats, urethral and penile stimulations always induced the ejaculatory motor pattern. Aqueous or hexane extract of Mondia whitei (20 mg/kg) prevented the expression of the ejaculatory motor pattern. The pro-ejaculatory effects of dopamine (0.1 μM/kg) were not abolished in spinal rats pre-treated with Mondia whitei extracts. Aqueous and methanolic stem bark extracts of Guibourtia tessmannii (20 mg/kg) induced fictive ejaculation characterized by rhythmic contractions of the bulbospongiosus muscles followed sometimes with expulsion of seminal plugs. In rats pre-treated with haloperidol (0.26 μM/kg), no ejaculatory motor pattern was recorded after intravenous injection of Guibourtia tessmannii extracts (20 mg/kg). Conclusion These results show that Mondia whitei possesses preventive effects on the expression of fictive ejaculation in spinal male rats, which is not mediated through dopaminergic pathway; on the contrary, the pro-ejaculatory activities of Guibourtia tessmannii require the integrity of dopaminergic system to exert its effects. The present findings further justify the ethno-medicinal claims of Mondia whitei and Guibourtia tessmannii.

Abstract
Procreation was an important moral and religious issue and aphrodisiacs were sought to ensure both male and female potency. Sexual dysfunction is an inability to achieve a normal sexual intercourse, including premature ejaculation, retrograded, retarded or inhibited ejaculation, erectile dysfunction, arousal difficulties (reduced libido), compulsive sexual behavior, orgasmic disorder, and failure of detumescence. The introduction of the first pharmacologically approved remedy for impotence, Viagra (sildenafil) in 1990s caused a wave of public attention, propelled in part by heavy advertising. The search for such substances dates back millennia. An aphrodisiac is an agent (food or drug) that arouses sexual desire. The hunt for natural supplement from medicinal plants is being intensified mainly because of its fewer side effects. In this review, we have mentioned the pharmacologically tested (either in man or animal or in both) aphrodisiac plants, which have claimed for its uses.

The aqueous crude extract of Montanoa frutescens produces anxiolytic-like effects similarly to diazepam in Wistar rats: involvement of GABAA receptor. JOURNAL OF ETHNOPHARMACOLOGY 2012; 143:592-598.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cihuapatli is the Nahuatl name assigned to some medicinal plants grouped in the genus Montanoa, where Montanoa frutescens (Family: Asteraceae, Tribe: Heliantheae) is included. The crude extract from these plants has been used for centuries in the Mexican traditional medicine as a remedy for reproductive impairments and mood disorders. Experimental studies have systematically corroborated the traditional use of cihuapatli on reproductive impairments and sexual motivation, however, the effect on mood and "nervous" disorders, remains to be explored. MATERIALS AND METHODS The anxiolytic-like effect of aqueous crude extract of M. frutescens (25, 50 and 75 mg/kg) was investigated in male Wistar rats evaluated in the elevated plus-maze and compared with several doses of diazepam (1, 2 and 4 mg/kg) as a reference anxiolytic drug. Picrotoxin (1 mg/kg), a noncompetitive antagonist of the GABA(A) receptor, was used in experimental procedures to evaluate if this receptor could be involved in the anxiolytic-like effects produced by M. frutescens. To discard hypoactivity, hyperactivity, or no changes associated with treatments, which could interfere with the behavioral activity in the elevated plus-maze, rats were subjected to the open field test. RESULTS M. frutescens at 50 mg/kg showed anxiolytic-like activity similarly to 2 mg/kg of diazepam, without disrupts in general motor activity. The anxiolytic-like effect of M. frutescens detected in the elevated plus-maze was blocked by picrotoxin, indicating that GABA(A) receptors are involved in the modulation of this effect. CONCLUSIONS The results corroborate the use of M. frutescens in folk Mexican ethnomedicine as a potential anxiolytic agent and suggest that this effect is mediated by the GABA(A) receptors. Additionally, some sedative effects with high doses of M. frutescens were detected in the present study.

BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2012; 12:8. [PMID: 22296876 PMCID: PMC3299611 DOI: 10.1186/1472-6882-12-8] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/19/2011] [Accepted: 02/01/2012] [Indexed: 12/13/2022]
Abstract
BACKGROUND Arctium lappa L. root has traditionally been recommended as an aphrodisiac agent. It is used to treat impotence and sterility in China, and Native Americans included the root in herbal preparations for women in labor. However, its use has not been scientifically validated. The present study therefore investigated the effects of aqueous extract of Arctium lappa L. roots on sexual behavior in normal male rats. METHODS Seventy-five albino male rats were randomly divided into five groups of 15 rats each. Rats in group 1 (control) were administered 10 mL/kg body weight distilled water (vehicle), group 2 received 60 mg/kg body weight sildenafil citrate (Viagra), while those in groups 3, 4, and 5 were given 300, 600, and 1,200 mg/kg body weight, respectively, of aqueous extract of Arctium lappa L. roots in the same volume. Female albino rats were made receptive by hormonal treatment. Sexual behavior parameters in male rats were monitored on days 3, 7 and 15 by pairing with receptive females (1:3). Male serum testosterone concentrations and potency were also determined. RESULTS Oral administration of Arctium lappa L. roots extract at 600 and 1,200 mg/kg body weight significantly increased the frequencies of mount, intromission, and ejaculation frequency (p < 0.05). The latencies of mount and intromission were significantly reduced and ejaculation latency was prolonged. Administration of the extract also reduced the post-ejaculatory interval. The standard drug (Viagra) was more effective than the extract. The extract significantly increased the frequencies of all components of penile reflexes as well as serum testosterone levels, compared with the distilled water controls. CONCLUSIONS The results of this study demonstrate that aqueous extract of Arctium lappa L. roots enhances sexual behavior in male rats. The aphrodisiac effects of the plant extract may be related to the presence of flavonoids, saponins, lignans and alkaloids, acting via a multitude of central and peripheral mechanisms. These results thus support the traditional use of Arctium lappa L. root extract for treating impotence and sterility.

Yakubu MT, Akanji MA. Effect of Aqueous Extract of Massularia acuminata Stem on Sexual Behaviour of Male Wistar Rats. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2011; 2011:738103.

Abstract
Ancient literature alluded to the use of a number of plants/preparations as sex enhancer. One of such botanicals is Massularia acuminata in which the stem has been acclaimed to be used as an aphrodisiac. Documented experiments or clinical data are, however, lacking. Therefore, this study was undertaken to evaluate the acclaimed aphrodisiac activity of M. acuminata stem. Sixty male rats were completely randomized into 4 groups (A-D) of 15 each. Rats in group A (control) were administered with 1 mL of distilled water (the vehicle) while those in groups B, C, and D were given same volume containing 250, 500, and 1000 mg/kg body weight of the extract, respectively. Sexual behaviour parameters were monitored in the male rats for day 1 (after a single dose), day 3 (after three doses, once daily), and day 5 (after five doses, once daily) by pairing with a receptive female (1 : 1). The male serum testosterone concentration was also determined. Cage side observation on the animals revealed proceptive behaviour (ear wiggling, darting, hopping, and lordosis) by the receptive female rats and precopulatory behaviour (chasing, anogenital sniffing and mounting) by the extract-treated male rats. The extract at 500, and 1000 mg/kg body weight significantly (P < .05) increased the frequencies of mount and intromission. In addition, the ejaculation latency was significantly prolonged (P < .05). The latencies of mount and intromission were reduced significantly whereas ejaculation frequency increased. The extract also reduced the postejaculatory interval of the animals. Computed percentages of index of libido, mounted, intromitted, ejaculated and copulatory efficiency were higher in the extract treated animals compared to the distilled water-administered control whereas the intercopulatory interval decreased significantly. The extract also significantly (P < .05) increased the serum testosterone content of the animals except in those administered with 250 mg/kg body weight on days 1 and 3. Data from this study identified that the aqueous extract of Massularia acuminata stem enhanced sexual behaviour in male rats. The improved sexual appetitive behaviour in male rats at the doses of 500 and 1000 mg/kg body weight of Massularia acuminata stem may be attributed, at least in part, to the alkaloids, saponins, and/or flavonoids since these phytochemicals has engorgement, androgen enhancing, and antioxidant properties.

Abstract
Résumé
Bridelia ferruginea (BF, Euphorbiaceae) est un arbre dont les écorces du tronc et les feuilles sont utilisées en médecine traditionnelle pour remédier à plusieurs problèmes et en particulier l’impuissance masculine. La présente étude vise à identifier les effets prosexuels (fréquences d’érection, de monte, d’intromission et d’éjaculation) des extraits aqueux (100 mg/kg) et éthanolique (100 mg/kg) des écorces du tronc de BF administrés par voie orale à des rats Wistar adultes mâles (intacts ou castrés) sexuellement inexpérimentés pendant zéro, un et sept jours. Le comportement sexuel des rats normaux recevant une administration unique de l’extrait aqueux de BF (100 mg/kg) a été aussi évalué après prétraitement par le L-omega-nitro-arginine methyl ester (Lω-NAME, 10 mg/kg), l’halopéridol (10 mg/kg) ou l’atropine (10 mg/kg). Les animaux témoins ont reçu per os de l’eau distillée (10 ml/kg) pour le témoin neutre et une injection sous-cutanée de testostérone propionate (20 mg/kg par jour pendant trois jours avant le début du test) pour le témoin positif. Les résultats de l’étude montrent que la durée du traitement a un impact significatif (p < 0,05) sur les fréquences d’érection pénienne, de monte et d’intromission aussi bien chez les rats normaux que chez les animaux castrés. Une tendance à l’augmentation des paramètres de performance sexuelle a été aussi observée. La fréquence d’intromission des rats intacts était plus élevée (p < 0,05–0,01) à J1 et particulièrement chez les rats recevant l’extrait aqueux de BF. Chez les rats castrés, par contre, seuls les animaux traités par la testostérone ont présenté une augmentation statistique (p < 0,01–0,001) des paramètres copulatoires. Les effets prosexuels de l’extrait aqueux de BF étaient abolis par l’atropine et l’halopéridol, tandis qu’une préadministration de Lω-NAME était sans effet sur l’activité copulatoire des animaux. Ces effets stimulants sexuels de BF pourraient être attribués à la présence des flavonoïdes et des stérols, substances bioactives qui agiraient par voie dopaminergique et/ou cholinergique, et soutiennent l’intérêt de l’emploi de BF en médecine traditionnelle comme stimulant sexuel.

Abstract
AIM OF THE STUDY To analyse the pro-ejaculatory properties of the proverbial Mexican plant oquichpatli, Senecio cardiophyllus, in an animal model for the study of ejaculation in spinal and anaesthetised male rats. MATERIALS AND METHODS The aqueous crude extract of Senecio cardiophyllus (at 0.4, 1.2 and 4 mg/kg) was i.v. administered to (a) anaesthetised and spinalised male rats after spinal cord transection and (b) anaesthetised and spinalised male rats previous to the inhibition of ejaculation elicited by repeated urethral stimulation. The motor pattern of ejaculation and the development of its inhibition were analysed under the influence of the aqueous crude extract of Senecio cardiophyllus and compared to urethrally induced ejaculations. RESULTS Systemic administration of the Senecio cardiophyllus aqueous crude extract, at all tested doses, induced the ejaculatory response in male rats. This response was featured by a statistically significant augmented number of ejaculatory discharges when compared to control animals. Oquichpatli-induced ejaculatory responses included the expression of autonomic and motor components of ejaculation and the potent expulsion of urethral contents and seminal plugs. Administration of oquichpatli aqueous crude extract prevented the inhibition of ejaculation elicited by urethral stimulation by promoting a statistically significant increase in the expression of ejaculatory motor patterns. CONCLUSION Present findings show by the first time that the aqueous crude extract of Senecio cardiophyllus possesses the ability to increase the ejaculatory capacity in male rats.

Abstract
Abstract
For millions of couples, the inability to have a child is a personal tragedy and a large proportion of childless people are confronted with social stigmatization (blame) and personal frustration. Formerly assigned to women, infertility of a couple is nowadays equitably distributed between the two sexes. Among the methods used to treat male infertility problems, medicinal plants have been used empirically as extracts, decoctions, fractions or semi-purified compounds. These herbal products are used in the treatment of a dysfunctioning of the libido, sexual asthenia, erection, and sperm disorders. Pharmacological activities of many of these plants have been shown in vitro using cells, in vivo (on laboratory animals) and human studies. For instance, extracts of Panax ginseng, Panax quinquefolius and Lepidium meyenii have shown positive effects on sexual desire; while extracts of Astragalus membranaceus, Asparagus racemous, Withania somnifera, Andrographis paniculata and Acanthopanax senticosus improved sperm parameters. Plants provide a treatment option that is affordable and available for infertile couples, and phytotherapy is an essential form of treatment in our health system. However, herbal products are still anarchically used in many regions and countries, and a great proportion of medicinal plants used traditionally to solve male reproductive disorders have not yet been scientifically evaluated. Therefore in this review, we have summarized most of the data dealing with the effects of plant extracts on mammalian reproductive functions.

Abstract
AIM OF THE STUDY In the present study, we examined the effect of Allium tuberosum seeds extract upon the expression of male rat sexual behavior, in order to know whether Allium tuberosum seeds extract possess aphrodisiac property. MATERIALS AND METHODS The aphrodisiac activity of Allium tuberosum seeds n-BuOH extract was investigated in male rats. The extract (500 mg/kg body weight/day) and L-dopa (100 mg/kg body weight/day) were administered orally by gavages for 40 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, 10, 20, 30 and 40. RESULTS The n-BuOH 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. CONCLUSIONS Present findings provide experimental evidence that the n-BuOH extract preparation of Allium tuberosum seeds possesses aphrodisiac property.

Abstract
Krachaidum (KD, Kaempferia parviflora Wall. Ex. Baker), a native plant of Southeast Asia, is traditionally used to enhance male sexual function. However, only few scientific data in support of this anecdote have been reported. The present study investigated the effects of feeding three different extracts of KD (alcohol, hexane, and water extracts) for 3-5 weeks on the reproductive organs, the aphrodisiac activity, fertility, sperm motility, and blood flow to the testis of male rats. Sexual performances (mount latency, mount frequency, ejaculatory latency, post-ejaculatory latency) and sperm motility were assessed by a video camera and computer-assisted sperm analysis respectively, while blood flow to the testis was measured by a directional pulsed Doppler flowmeter. The results showed that all extracts of KD had virtually no effect on the reproductive organ weights even after 5 weeks. However, administration of the alcohol extract at a dose of 70 mg/kg body weight (BW)/day for 4 weeks significantly decreased mount and ejaculatory latencies when compared with the control. By contrast, hexane and water extracts had no influence on any sexual behavior parameters. All types of extracts of KD had no effect on fertility or sperm motility. On the other hand, alcohol extract produced a significant increase in blood flow to the testis without affecting the heart rate and mean arterial blood pressure. In a separate study, an acute effect of alcohol extract of KD on blood flow to the testis was investigated. Intravenous injection of KD at doses of 10, 20, and 40 mg/kg BW caused dose-dependent increases in blood flow to the testis. The results indicate that alcohol extract of KD had an aphrodisiac activity probably via a marked increase in blood flow to the testis.

Abstract
The effects of Mondia whitei Hook (Skeels) were studied on the sexual behaviour and some fertility parameters of sexually inexperienced male rats. Animals were orally administered 100 mg/kg and 500 mg/kg of body weight (b.w) of either the aqueous or the hexane extracts of Mondia whitei whilst the control group received 10 mL/kg b.w of 0.3% Tween 80 once/day for 14 days. Their sexual behaviour was monitored on days 0, 1, 7 and 14 days of treatment and 14 days post-treatment. Some fertility parameters (index libido, quantal pregnancy, fertility index) of the treated rat were evaluated on day 13 of treatment by pairing it overnight with two proestrus females. Results showed that Mondia whitei extracts significantly (p<0.001) reduced the mount latency and the hexane extract was found to be more efficient than the aqueous extract. The treatment had no significant effect (p>0.05) on intromission, ejaculation and erection. The fertility of the animals remained unaffected. It's concluded that Mondia whitei had sexual enhancement of the sexually inexperienced male rats.

Abstract
In the present study, the pro-sexual effect of the cihuapatli (Montanoa tomentosa) and its possible pro-ejaculatory properties in spinal male rats were examined. Systemic administration of the aqueous crude extracts of Montanoa tomentosa exerted a pro-ejaculatory effect and produced an increase in the number of discharges in the ejaculatory motor patterns in the spinal rats. The cihuapatli-induced ejaculatory responses included the expression of penile erections and penile movements and the potent expulsion of urethral contents and in some cases the expulsion of seminal plugs. The cihuapatli-induced ejaculatory motor patterns were similar to that obtained after systemic oxytocin. Cihuapatli- and oxytocin-induced ejaculatory motor responses and the penile erections and movements were abolished by the pre-treatment with hexamethonium, a selective oxytocin antagonist. Present data show that the cihuapatli extract acts directly at the spinal system in charge of the expression of the ejaculatory motor patterns and suggest that the aqueous crude extract exerts its aphrodisiacs properties by increasing sexual potency acting as an oxytocic agent.

Abstract
Lycium barbarum, a famous Chinese medicinal herb, has a long history of use as a traditional remedy for male infertility. Polysaccharides are the most important functional constituent in L. barbarum fruits. We systematically investigated the effect of L. barbarum polysaccharides (LBP) on rat testis damage induced by a physical factor (43 degrees C heat exposure), on DNA damage of mouse testicular cells induced by a chemical factor (H2O2), and on sexual behavior and reproductive function of hemicastrated male rats. The results showed that LBP provided a protective effect against the testicular tissue damage induced by heat exposure. When compared with negative control, a suitable concentration of LBP significantly increased testis and epididymis weights, improved superoxide dismutase (SOD) activity, and raised sexual hormone levels in the damaged rat testes. LBP had a dose-dependent protective effect against DNA oxidative damage of mouse testicular cells induced by H2O2. LBP improved the copulatory performance and reproductive function of hemicastrated male rats, such as shortened penis erection latency and mount latency, regulated secretion of sexual hormones and increased hormone levels, raised accessory sexual organ weights, and improved sperm quantity and quality. The present findings support the folk reputation of L. barbarum fruits as an aphrodisiac and fertility-facilitating agent, and provide scientific evidence for a basis for the extensive use of L. barbarum fruits as a traditional remedy for male infertility in China.
