PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2021; 88:153596. [PMID: 34092456 DOI: 10.1016/j.phymed.2021.153596] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/23/2020] [Revised: 05/01/2021] [Accepted: 05/11/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND Azadirachta indica A. Juss. is an Indian medicinal plant with innumerable pharmacological properties. Studies have proven that the phytochemicals from neem possess remarkable contraceptive abilities with limited knowledge on its mechanism of action. PURPOSE The present review aims to summarize the efficiency of A. indica treatment as a contraceptive. METHODS The Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines were used. Published scientific articles on antifertility, antispermatogenic, antiovulation, hormone altering, contraceptive, and abortifacient activities of A. indica were collected from reputed Journals from 1980 to 2020 using electronic databases. Specific keywords search was completed to collect numerous articles with unique experiment design and significant results. This was followed by the selection of the requisite articles based on the criteria designed by the authors. Data extraction was based on the common research elements included in the articles. RESULTS A total of 27 studies were considered for reviewing, which included key pharmacological investigations. In the beginning, authors evaluated a number of publications on the contraceptive properties of A. indica, in which it was revealed that most of the publications were made between 2005 and 2009. All the collected articles were categorised and reviewed as antifertility, antispermatogenic, antiovulation, hormone altering, contraceptive, and abortifacient. Authors also assessed studies based on the plant parts used for pharmacological evaluations including leaves, seeds, stem-bark, and flowers. The article was primarily divided into different sections based on the previous works of authors on phytochemistry and pharmacological review articles. CONCLUSION Although A. indica is not reported with the complete alleviation of reproductive system in both male and female animal models, studies have proven its efficacy as a contraceptive. Extracts and phytochemicals from neem neither reduced the libido nor retarded the growth of secondary sexual characters, thus indicating only a temporary and reversible contraceptive activity. However, there is a dearth for clinical studies to prove the efficacy of A. indica as a herbal contraceptive.

[PMID: 33597315 PMCID: PMC8225478 DOI: 10.5115/acb.20.161] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2020] [Revised: 09/25/2020] [Accepted: 01/07/2021] [Indexed: 01/20/2023] Open
Abstract
Nicotine as a toxic agent in cigarette smoke impairs the reproductive system. Sambucus ebulus extract (SEE) is shown to have some beneficial effects such as antioxidant properties. The aim of this study was to evaluate the effects of SEE on the hormones of the pituitary-gonadal axis, lipid peroxidation index, antioxidant enzymes, spermatogenesis, and epididymal sperm parameters in male mice treated with nicotine. Adult male mice were divided into five groups; A: normal saline, B: 1 mg/kg nicotine, C: 1 mg/kg nicotine and 10 mg/kg SEE, D: 1 mg/kg nicotine and 50 mg/kg SEE, D: 1 mg/kg nicotine and 100 mg/kg SEE. Treatments lasted for 35 days. The spermicidal activity of SEE was tested in vitro. Sperm count, motility and morphology were assessed for fertility. Serum testosterone, prolactin and luteinizing hormone (LH) were measured, using ELISA. Serum malondialdehyde (MDA), catalase (CAT), and superoxide dismutase (SOD) activity were measured, using colorimetric assays. Spermatogenesis was evaluated by Johnsen’s score and morphometry in histological slides. SEE at different doses did not have any spermicidal activity. Sperm parameters were reduced in the nicotine-treated group, compared with controls (P<0.01). Nicotine reduced testosterone and LH levels (P<0.01) and increased prolactin (P<0.01). A hike in MDA and a reduction in SOD activity without change on CAT, were observed in the nicotine group. Nicotine caused hypospermatogenesis. SEE improved most of the above-mentioned parameters, especially in the doses of 50 and 100 mg/kg. Beneficial effects of SEE in the doses of 50 and 100 mg/kg on male reproduction impairment, induced by nicotine might be partly attributed to the reduction of oxidative stress and changes in the hormones of the pituitary-gonadal axis.

Abstract
Piperine (PIP) is an alkaloid present in several species of piper, mainly Piper nigrum Linn. and P. longum, among other species. The present article provides a comprehensive review of PIP research in the last years concerning its chemical properties, synthesis, absorption, metabolism, bioavailability and toxicity. The reviewed PIP literature has shown many pharmacological properties, such as antidiabetic, antidiarrheal, antioxidant, antibacterial, and anti-parasitic activity of PIP. However, its low solubility and absorption make its application challenging. This review also includes advances in the development of nanosystems containing PIP, including liposomes, micelles, metal nanoparticles, nanofibers, polymeric nanoparticles, and solid-lipid nanoparticles. Finally, we discuss different in vitro and in vivo studies to evaluate the biological activity of this drug, as well as some methods for the synthesis of nanosystems and their physical characteristics.

Abstract
BACKGROUND The world's population is still growing, having an impact on the environment and the economic growth of developing countries; so that, there is a particular interest in the development of new fertility control methods, focused on male contraception. OBJECTIVE The objective of this study was to evaluate the effect of methanolic extracts of leaf and fruit of Azadirachta indica on sperm quality and testicular histology of Long Evans rats. METHODS Antifertility effects of a methanolic leaf and fruit extracts of A. indica on 24 male rats were investigated. The animals were randomly divided into two control groups and four treatment groups (n=4). Doses of the leaf and fruit extract were given at concentrations of 100 and 200 μg mL-1. RESULTS A significant decrease in the viability of sperm cells was observed. The leaf extract at a concentration of 200 μg mL-1 inhibited cell viability compared to the negative control (p< 0.001). The percentage of abnormal cells in leaf extract was shown in 100 and 200 μg mL-1, the conditions at which a higher percentage of morphological irregularities of observed (15% and 16% respectively). The results show that there was cellular detachment in the seminiferous epithelium in the experimental groups treated with methanolic extracts. Sperm death was observed without decreasing the number of sperm. CONCLUSION The methanolic extracts of Azadirachta indica have a modulating effect on the spermatogenesis of experimental rats through sperm morphological alterations.

Abstract
AbstractBackgroundAcknowledging population control to be an essential step for global health promotes wide research study in the area of male contraception. Although there are a great number of synthetic contraceptives available in the market, they have plenty of adverse effects. Different potential strategies for male contraception were investigated over a long period time consisting of hormonal, chemical, and immunological interventions, although these methods showed good antifertility results with low failure rates relative to condoms.Main textThis review is based upon the concept of herbal contraceptives which are an effective method for controlling the fertility of animals and humans. This review has highlighted herbal medicinal plants and plant extracts which have been reported to possess significant antifertility action in males. The review considers those plants which are used traditionally for their spermicidal and antispermatogenic activities and imbalance essential hormones for fertility purposes and plants with reported animal studies as well as some with human studies for antifertility effect along with their doses, chemical constituents, and mechanism of action of the antifertility effect of the plants. This review also explains the phases of sperm formation, hormone production, and the mechanism of male contraceptives.ConclusionAs far as the relevance of the current review is discussed, it might be quite useful in generating monographs on plants and recommendations on their use. A lot of the plant species listed here might appear promising as effective alternative oral fertility-regulating agents in males. Therefore, significant research into the chemical and biological properties of such less-explored plants is still needed to determine their contraceptive efficacy and also to possibly define their toxic effects so that these ingredients can be utilized with confidence to regulate male fertility. The new inventions in this field are necessary to concentrate on modern, more potent drugs with less harmful content and that are self-administrable, less costly, and entirely reversible.

Abstract
Azadirachta indica, commonly known as neem, is an evergreen tree of the tropics and sub-tropics native to the Indian subcontinent with demonstrated ethnomedicinal value and importance in agriculture as well as in the pharmaceutical industry. This ancient medicinal tree, often called the "wonder tree", is regarded as a chemical factory of diverse and complex compounds with a plethora of structural scaffolds that is very difficult to mimic by chemical synthesis. Such multifaceted chemical diversity leads to a fantastic repertoire of functional traits, encompassing a wide variety of biological activity and unique modes of action against specific and generalist pathogens and pests. Until now, more than 400 compounds have been isolated from different parts of neem including important bioactive secondary metabolites such as azadirachtin, nimbidin, nimbin, nimbolide, gedunin, and many more. In addition to its insecticidal property, the plant is also known for antimicrobial, antimalarial, antiviral, anti-inflammatory, analgesic, antipyretic, hypoglycaemic, antiulcer, antifertility, anticarcinogenic, hepatoprotective, antioxidant, anxiolytic, molluscicidal, acaricidal, and antifilarial properties. Notwithstanding the chemical and biological virtuosity of neem, it has also been extensively explored for associated microorganisms, especially a class of mutualists called endophytic microorganisms (or endophytes). More than 30 compounds, including neem "mimetic" compounds, have been reported from endophytes harbored in the neem trees in different ecological niches. In this review, we provide an informative and in-depth overview of the topic that can serve as a point of reference for an understanding of the functions and applications of a medicinal plant such as neem, including associated endophytes, within the overall theme of phytopathology. Our review further exemplifies the already-noted current surge of interest in plant and microbial natural products for implications both within the ecological and clinical settings, for a more secure and sustainable future.

Abstract
BACKGROUND The exploration of the biological assessment of technical azadirachtin, a tetranortritarpinoid from the neem seed kernel, was reviewed. The present study was, therefore, designed to evaluate the dose-dependent in vitro effects of azadirachtin-A, particularly on the functional studies and determination of molecular events, which are critical in the process of sperm capacitation. METHODS To assess the effects of the azadirachtin-A on the functional studies, sperm capacitation, the total sperm adenosine triphosphate levels, acrosome reaction (AR), the sperm-egg interaction and the determination of molecular events like cyclic adenosine-3',5'-monophosphate and calcium levels, the appropriate volumes of the sperm suspension were added to the medium to a final concentration of 1×106 sperm/mL and incubated in a humidified atmosphere of 5% CO2 in air at 37°C. The increasing quantities 0.5-2.0 mM/mL and the equivalent volumes of 50% dimethyl sulfoxide were added to the control dishes prior to the addition of spermatozoa and then observed at various time-points for motility and other analyses. RESULTS Results revealed the dose- and time-dependent decrease in the functional consequence of capacitation, i.e. the percentage of motile spermatozoa, motility score and sperm motility index, levels of molecular events in spermatozoa, followed by declined spontaneous AR leading to lesser binding of the cauda epididymal sperm to the Zona pellucida. CONCLUSIONS The findings confirm the inhibition of rat sperm motility by blocking some biochemical pathways like energy utilization. They also demonstrate that sperm capacitation is associated with the decrease in AR and that the levels of molecular events in spermatozoa can guide us towards the development of a new male contraceptive constituent.

Abstract
India is a home for a large variety of plants with remarkable medicinal and pharmacological value. Traditional medicine in the form of Ayurveda, Siddha and Unani has used many of these plants since ancient days for treating and curing various ailments of the body. When it comes to issues related to reproductive health, people still hesitate to discuss and/or accept it openly and hence look for alternate and natural remedies. The various tribal populations distributed across different parts of the country still use these plant extracts in various formulations for maintenance of good health. The medical utilities of several of these plants have been documented; however, there are many more, whose potential is yet to be explored. This review discusses the role of various plants grown in the Indian subcontinent that have been widely used in maintaining various aspects of reproductive health in men such as infertility, aphrodisiac, contraception, libido, sexually transmitted infections and reproductive tract cancers as well as in treating chronic disorders.

Abstract
Neem (Azadirachta indica L.) leaf has been widely used in ayurvedic system of medicine for fertility regulation for a long time. The molecular mechanism by which neem leaf regulates female fertility remains poorly understood. Animal studies suggest that aqueous neem leaf extract (NLE) induces reactive oxygen species (ROS) - mediated granulosa cell apoptosis. Granulosa cell apoptosis deprives oocytes from nutrients, survival factors and cell cycle proteins required for the achievement of meiotic competency of follicular oocytes prior to ovulation. Under this situation, follicular oocyte becomes more susceptible towards apoptosis after ovulation. The increased level of hydrogen peroxide (H2O2) inside the follicular fluid results in the transfer of H2O2 from follicular fluid to the oocyte. The increased level of H2O2 induces p53 activation and over expression of Bax protein that modulates mitochondrial membrane potential and trigger cytochrome c release. The increased cytosolic cytochrome c level induces caspase-9 and caspase-3 activities that trigger destruction of structural and specific proteins leading to DNA fragmentation and thereby oocyte apoptosis. Based on these animal studies, we propose that NLE induces generation of ROS and mitochondria-mediated apoptosis both in granulosa cells as well as in follicular oocyte. The induction of apoptosis deteriorates oocyte quality and thereby limits reproductive outcome in mammals.

Abstract
The neurotoxic effects of a commercial formulation of Azadirachta indica A. Juss, also called neem or nim, in adult zebrafish were determined using behavioral models. General activity, anxiety-like effects, and learning and memory in a passive avoidance task were assessed after exposure to 20 or 40 μl/L neem. The results showed that 20 μl/L neem reduced the number of runs. Both neem concentrations increased the number of climbs to the water surface, and 40 μl/L increased the number of tremors. In the anxiety test, the 20 μl/L dose increased the number of entries in the light side compared with controls, but the latency to enter the dark side and the freezing behavior in this side did not changed. In relation to controls, the 40 μl/L neem reduced the latency to enter in the light side, did not change the number of entries in this side and increased freezing behavior in the light side. In the passive avoidance test, pre-training and pre-test neem exposure to 40 μl/L decreased the response to the learning task. Thus, no impairment was observed in this behavioral test. We conclude that neem reduced general activity and increased anxiety-like behavior but did not affect learning and memory.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Ricinus communis L. (Rc), of Euphorbiaceae family is a widespread plant in tropical regions and it is used in traditional medicines as an antifertility agent in India and different parts of the world. AIM OF THE STUDY The aim of the present study is to revalidate the ethnobotanical knowledge by evaluating the activity of only crude stem bark extracts of Rc. In this study, effects of extracts on male contraceptive efficacy were experimented in vitro with human sperm sample. The work is based on primordial and contemporary therapeutic uses of this plant. MATERIALS AND METHODS In this study, dose of petroleum ether extract, ethyl acetate extract, acetone extract and lyophilised aqueous extract of Rc were added to fresh human semen in 1:1 volumetric ratio. As the aqueous extract showed a promising result in 1:1 ratio, therefore, the Hypo-osmotic swelling test (HOS), Nuclear chromatin decondensation test (NCD) and Acrosomal status and function test (AFT) were also carried out with the aqueous extract of Rc. RESULTS The sperm immobilisation effects of the extract appeared immediately in a dose-dependent manner when the samples were treated with four different extracts of this plant. At a concentration of 100mg/mL, 100% (p<0.001 and p<0.05) sperms lost their progressive motility. At a concentration of 300 mg/mL, 100% (p<0.001 and p<0.05) became immotile when treated with aqueous extract. There was 88% (p<0.001 and p<0.05) morphological deformities in sperm sample due the effect of aqueous extract when they were tested for HOS and 91% (p<0.05) sperms behaved against NCD as compared to control group. Also there was a distinct decline (p<0.05) in AFT with increase in dosage concentration. CONCLUSION The findings of the study revealed that aqueous stem bark extract of the plant showed dose dependent loss of sperm motility by influencing the morphological deformation, blockage in nuclear envelope and distinct declination in acrosomal status of spermatozoa. This research, thus, opens up scope for future exploration of bark of the plant as commercial source of new male contraceptive.

Abstract
Male contraceptive development in the present scenario is most viable aspect of research due to uncontrolled population growth in the world. In this respect investigators are busy to find out a safe male contraceptive drug. Researchers have started their finding for a suitable drug from natural sources because these are safe and easily acceptable for common man, most of natural sources are plants and their products. In this review 137 plants and their effects on reproduction and reproductive physiology are summarized. Some of them have intense effect on male reproductive system and do not produce any side effects. Reproductive toxicological studies are also important aspects of these kinds of researches, so it is important that drugs are safe and widely acceptable. An ideal male contraceptive can influence semen, testes, hormone level, accessory reproductive organs and general physiology of animals and produced some alterations. Many plants in this review are showing antifertility as well as antispermatogenic effects, so these may be used for further study for contraceptives development but it is important to find out the mechanism of reaction and further laboratory and clinical research on some plants are needed for final male contraceptive drug development. In conclusion this review will help for finding suitable plant products for male contraceptive clinical and laboratory studies.

Abstract
Contraceptive properties of seaweeds are still stands as lacuna; in this context, the screening of in vitro male contraceptive properties of crude ethanolic extract of Indian seaweeds against normal human sperm is carried out. In total, twelve seaweeds were screened for in vitro spermicidal activity. Among these twelve seaweeds, Halimeda gracilis showed 100% inhibition of human spermatozoa at 10 mg ml(-1) concentration in 20 s and its EC50 value was 2.05 mg ml(-1) in 20 s. Further, dose- and time-dependent spermicidal assay revealed that the sperm was completely immobilised for 20 s. Plasma membrane of sperm was damaged due to the exposure of H. gracilis extract. MTT assay with H. gracilis extract showed 88.5% of cytotoxic incidence. H. gracilis extract tested for cytotoxicity against Artemia salina recorded LC50 value of 34.8 μg ml(-1) . Phytochemical analysis of H. gracilis extract evidenced the presence of alkaloids, flavonoids, proteins and sugars. Results of this study clearly inferred that the synergistic effect of active principles reside within the H. gracilis extract had shown better contraceptive activity.

Abstract
BACKGROUND An alarming increase in global population is the root cause of poverty, malnutrition, sexually transmitted infections (STIs) and many other social problems. Microbicidal spermicides possessing dual function of contraception and STI protection can effectively combat this problem, and their development is of utmost importance at present. STUDY DESIGN A major metabolite isolated from Shorea robusta resin was spectroscopically characterized as asiatic acid. Spermicidal efficacy of the isolate was evaluated in vitro by a modified Sander-Cramer test. The mode of spermicidal action was assessed by (a) double fluoroprobe staining, (b) hypoosmotic swelling test and (c) scanning electron microscopy. Antimicrobial efficacy was assessed by disc diffusion and broth dilution methods using human isolates of bacteria (Escherichia coli ATCC 25938 and Pseudomonas aeruginosa 71) and fungus (Candida tropicalis). RESULTS The minimum effective concentration of asiatic acid that induced instantaneous immobilization of rat spermatozoa in vitro was 125 mcg/mL. The mechanism of action involved disruption of sperm plasma membrane. The microbicidal efficacy was found to be moderate for vaginal pathogens, with no effect on normal vaginal flora. CONCLUSION Asiatic acid possesses appreciable spermicidal and microbicidal potential and may be explored as an effective microbicidal spermicide.

Abstract
Résumé
Le refus des solutions « chimiques », souvent jugées suspectes, mène un nombre croissant de contemporains à rechercher une alternative naturelle chaque fois qu’elle existe. Le domaine médical — et en particulier celui qui concerne la reproduction — échappe d’autant moins à cette aspiration qu’il s’y trouve des bases historiques multimillénaires. Il a également des justifications économiques dans tous les pays où l’accès aux médicaments est problématique, sinon illusoire. La contraception masculine n’est pas oubliée dans ce contexte; en particulier dans les pays émergents où la natalité élevée pose un problème de société. Des principes actifs extraits de plantes ont fait — et font encore-l’objet de recherches très circonstanciées. Il existe de bonnes raisons de penser que des solutions existent dans ce registre. Des tests menés in vivo chez l’animal (surtout), mais aussi in vitro sur des spermatozoïdes isolés concluent à l’existence d’effets centraux, périphériques ou spermicides significatifs. Les vertus thérapeutiques souvent multiples des plantes concernées mènent toutefois à rester vigilants pour ne pas associer, en cas d’utilisation systémique, un effet secondaire indésirable à l’effet contraceptif recherché.

Abstract
The study was undertaken to evaluate the anti-spermatogenic efficacy of ethanol extract of stem bark of Dalbergia sissoo Roxb. For the in vitro study, semen samples were obtained from 15 healthy fertile men aged 25-35 years. Sperm motility was examined by the Sander-Cramer method. A dose-dependent and time-dependent effect of ethanol extract on sperm motility and sperm viability were observed. Various concentrations affected the motility of sperm. Ethanol extract at a concentration of 20 mg/mL caused complete immobilization within 3 minutes. Sperm viability and hypo-osmotic swelling was significantly reduced at this concentration. The in vivo studies were carried out on Swiss male albino mice. Ethanol extract at a dose of 200 mg/kg body weight resulted in a significant decrease (p<0.001) in weight of the testis and epididymis. A significant decrease (p<0.01) in sperm motility and sperm count in the epididymis were observed. Histological changes in the epididymis and testis were also investigated.

Abstract
BACKGROUND Spermicides represent one of the methods of contraception. The synthetic agents available as spermicides produce severe side effects. Hence, there is a need to replace these agents with safe and effective agents such as plant-based contraceptive agents. STUDY DESIGN The objective of the present study was to develop and evaluate a stable, safe, effective and easily acceptable contraceptive delivery system containing herbal drug. Efforts were made to evaluate the contraceptive potential of the hydroalcoholic extract from the seeds of Annona squamosa Linn. and the vaginal gel HerbOshield™ containing the extract. RESULTS Spermicidal effect was evaluated in vitro using healthy human spermatozoa and in vivo in rats. The in vitro results demonstrated that HerbOshield™ vaginal gel is an effective spermicide. At a 100-mg/mL dose, complete immobilization of human spermatozoa was observed within 20 s. None of the treated animals conceived, indicating 100% contraceptive effect as compared to Gynol II, a nonoxynol-9-containing marketed formulation, which showed only 67% contraceptive effect in vivo. HerbOshield™ vaginal gel was found to be safe in animals during a 14-day toxicity study. CONCLUSIONS HerbOshield™ vaginal gel was found to be safe and effective in rats and could be developed as a potential vaginal contraceptive for future use in humans.

Abstract
The present study aimed at investigating the effects of essential oil of Trachyspermum ammi fruits, an oil-bearing plant of Apiaceae family, on human sperm viability and membrane integrity. Chemical compositions of the oil were analysed by GC-MS. Thirty compounds representing 91.39% of the total oil were identified. The viability and membrane integrity of human spermatozoa were assessed using minimum effective dose (MED) concentration (125 μg ml(-1)) of the oil. Sperm treated with essential oil showed a significant decrease (P < 0.05) in viability assessed by eosin-nigrosin and fluorescence dual staining. Moreover, the treated sperm also showed a significant loss (P < 0.05) of functional mitochondria and antioxidant enzyme, catalase (EC 1.11.1.6, CAT), when compared to control. The cholesterol:phospholipid ratio was also increased (P < 0.05) in treated sperm when compared to control, which is an indicator of loss of binding ability of human spermatozoa to the zona pellucida. The scanning electron microscopic studies demonstrated the loss of membrane integrity in essential oil-treated human spermatozoa, which showed vacuolation, swelling of acrosomal cap, detachment of head portion and tail coiling. Present observations indicate the spermicidal property of essential oil of T. ammi fruits, which could be helpful to develop medicinal preparations as a male contraceptive.

Abstract
This study was conducted to determine the spermicidal and contraceptive efficacy of essential oil of Trachyspermum ammi on human sperm in vitro. Chemical compositions of the oil were analyzed by GC-MS. Nearly 30 compounds representing 91.39% of the total oil were identified. The minimum effective dose (MED) of essential oil of T. ammi that induced instant immobilization of human spermatozoa in vitro was 125 μg/mL. The motility was also irreversible. All of the human sperms were found to be non viable within 10 min at this concentration. The activity of acrosomal enzyme was reduced and a significant releases of 5'-nucleotidase into the surrounding medium was noted after treatment with MED concentration of essential oil, indicating the plasma membrane degradation of the sperm. The maximum number of human sperm failed to decondense when treated with MED concentration of essential oil. The morphological deformities of sperm plasma membrane were evidenced by SEM, which showed vaculation, detachment of heads and tail coiling. The present research indicates that essential oil of T. ammi possesses appreciable spermicidal potential, which may be explored as an effective constituent of vaginal contraceptive.

Abstract
BACKGROUND The spermicidal activity of oleanolic acid 3-β-D-glucuronide (OAG), an active principle isolated from root extracts of Sesbania sesban, was evaluated. STUDY DESIGN Under the Sander-Cramer test criteria, the sperm-immobilizing activity of OAG was studied using highly motile rat sperm. Sperm mortality and membrane integrity were assessed by supravital staining, hypo-osmotic swelling (HOS), transmission electron microscopy (TEM) and sperm membrane lipid peroxidation (LPO). In vitro microbicidal potential and hemolytic index of OAG were examined in Lactobacillus culture and rat red blood corpuscles (RBCs), respectively. Post-intravaginal OAG application, the in vivo contraceptive efficacy was evaluated in rats. Ames test determined the carcinogenic potential of OAG. RESULTS The minimum effective concentration (MEC) of OAG was 50 mcg/mL. More than 97% of the OAG-treated sperm lost their HOS responsiveness in a dose-dependent manner. TEM and LPO revealed that OAG affected the sperm membrane integrity. OAG declined fertility to zero, was nonmutagenic and was not harmful to lactobacillus. CONCLUSION OAG has significant spermicidal activity that may be explored further.

Abstract
The seed extracts of Madhuca latifolia were reported to have spermicidal activity. The current investigation identified the spermicidal component of the extracts and evaluated its spermicidal potential in vitro. As characterized by infrared, mass, and nuclear magnetic resonance (NMR) spectral analyses, Mi-saponin A (MSA) was found to be the most potent component among a mixture of saponins. The mean effective concentrations of MSA that induced irreversible immobilization were 320 microg/mL for rat and 500 microg/mL for human sperm, as against the respective concentrations of 350 and 550 microg/mL of nonoxynol 9 (N-9). The mode of spermicidal action was evaluated by a battery of tests including (a) double fluoroprobe staining for sperm viability, (b) hypoosmotic swelling test and, assays for 5' nucleotidase and acrosin for physiological integrity of sperm plasma membrane, (c) scanning and transmission electron microscopy for sperm membrane ultrastructure, and (d) plasma membrane lipid peroxidation (LPO). The observations, taken together, were interpreted to mean that the spermicidal effect of MSA involved increased membrane LPO leading to structural and functional disintegration of sperm plasma membrane and acrosomal vesicle. A comparative in vitro cytotoxicity study in human vaginal keratocyte (Vk2/E6E7) and endocervical (End/E6E7) cell lines demonstrated that the 50% cell cytotoxicity (CC(50)) values, and consequently the safety indices, for MSA were >or= 8-fold higher as compared to those of N-9. In conclusion, MSA is a potent spermicidal molecule that may be explored further for its suitability as an effective component of vaginal contraceptive.

Abstract
AIM OF THE STUDY Contraceptive plants which were introduced by folk in traditional remedies are investigated worldwide. In this study, the contraceptive effects of Ruta graveolens L., which has been mentioned for male contraceptive in Iranian traditional folk medicine, was experimented on human sperm. MATERIALS AND METHODS Different doses of lyophilized aqueous extract of Ruta graveolens L. were added to an amount of fresh semen, containing 10(6) cells in a 1:1 volumic ratio. Motility and viability of cells, DNA status, mitochondrial activity and sperm revival tests were carried out. RESULTS The sperm immobilization effects of the extract appeared immediately in a does-dependent manner and 100% of the sperms became immotile at a concentration of 100mg/ml but other parameters were intact. After washing the sperms, motility was returned in 30.8+/-3.2% of the sperms, besides coiled tails in 38.6+/-5.5% of the treated cells, in comparison to 12.5+/-2.0% of the control group (p=0.001). The part of the extract, responsible for immobilization of the sperms was stable upon boiling. CONCLUSIONS As the cells were alive and immotile, probably some ionic currents are blocked by a thermostable component of the plant which can be promising as a new male channel blocker contraceptive.

Abstract
Currently there exists increasing preoccupation concerning sexual and reproductive health among teenagers; in spite of the availability of different contraceptive methods, the number of undesired pregnancies is steadily increasing. Among the products presently available for birth control, spermicides are a means that can be totally controlled by the woman and are very reliable compared to other contraceptives in common use. However, they cause irritation in the vaginal epithelium due to their tensoactive effect on cellular membranes which might enhance the risk of acquiring sexually transmissible diseases. In searching for new alternatives, it was observed that a wide variety of plants have spermicidal activity. Hence it is interesting to consider potential contraceptives of vegetable origin, as they may constitute a key tool to prevent undesired pregnancies in general, and in particular in vulnerable groups such as teenagers and young women.

Souad K, Ali S, Mounir A, Mounir TM. Spermicidal activity of extract from Cestrum parqui. Contraception 2006; 75:152-6. [PMID: 17241846 DOI: 10.1016/j.contraception.2006.10.006] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2006] [Revised: 10/06/2006] [Accepted: 10/10/2006] [Indexed: 11/19/2022]
Abstract
OBJECTIVE The leaf extract of Cestrum parqui was examined for its effects on sperm motility in vitro. METHODS Washed sperm were prepared by discontinuous buoyant density gradient centrifugation and incubated with varying concentrations of extract from C. parqui (40-250 microg/mL) at 37 degrees C and 5% CO(2). Sperm motility and viability were assessed at different intervals ranging from 5 to 240 min. Morphological changes in human ejaculated spermatozoa after exposure to the extract were evaluated under transmission electron microscope. RESULTS A dose- and time-dependent effect of this extract on sperm motility and viability was observed. The maximal spermicidal effect was observed with a 250-microg/mL dose of the extract. Transmission electron microscope revealed a significant damage to sperm membrane in both head and acrosomal membranes, notable swelling and disruption. CONCLUSION The present study indicates that this natural extract has potential spermicidal effect in vitro.

Kumar S, Biswas S, Mandal D, Roy HN, Chakraborty S, Kabir SN, Banerjee S, Mondal NB. Chenopodium album seed extract: a potent sperm-immobilizing agent both in vitro and in vivo. Contraception 2006; 75:71-8. [PMID: 17161128 DOI: 10.1016/j.contraception.2006.07.015] [Citation(s) in RCA: 24] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2005] [Revised: 05/30/2006] [Accepted: 07/21/2006] [Indexed: 11/22/2022]
Abstract
PURPOSE Aqueous decoction of Chenopodium album seeds (CAD) was assessed for its sperm-immobilizing and contraceptive efficacy in laboratory mammals. METHOD Spermicidal efficacy was evaluated in vitro by a modified Sander-Cramer test. The mode of spermicidal action was assessed by (a) supravital and double fluoroprobe staining of sperm, (b) hypoosmotic swelling tests and (c) transmission electron microscopy. Contraceptive efficacy was evaluated by intrauterine and vaginal application of CAD in rats and rabbits, respectively, followed by their mating and evaluation of pregnancy outcomes. RESULTS The minimum effective concentration of CAD that induced instantaneous immobilization of rat spermatozoa in vitro was 2 mg/mL. The mechanism of CAD action involved disintegration of sperm plasma membrane and dissolution of acrosomal cap causing sperm death. Fertilization of oocytes and establishment of implantation were prevented in the uterine horn that was administered with CAD, while these events occurred unhindered in the untreated contralateral side. In rabbit, intravaginal application of CAD significantly blocked the establishment of pregnancy. CONCLUSION CAD possesses appreciable spermicidal potential, which may be explored as an effector constituent of vaginal contraceptive.

Abstract
OBJECTIVE To determine whether aqueous neem leaf extract (NLE) could induce degeneration of rat oocytes and, if so, whether apoptosis is involved during NLE-induced degeneration of oocytes cultured in vitro. DESIGN A controlled prospective study. SETTING Laboratory research setting at Department of Reproductive Biomedicine of the Institute. ANIMAL(S) Fifty-four sexually immature female rats that were 24-25 days of age. INTERVENTION(S) The immature female rats were injected with 10 IU pregnant mare serum gonadotropin for 48 h followed by 10 IU human chorionic gonadotropin (hCG) for 16 h. After 16 h, the rats were killed and ovulated cumulus oocyte complexes were collected from the oviduct. Cumulus-enclosed as well as denuded oocytes were used in the present study. MAIN OUTCOME MEASURE(S) Rates of shrinkage, membrane leakage, degeneration, assessment of morphological apoptotic changes, bax protein expression, and DNA fragmentation. RESULT(S) The NLE induced morphologic apoptotic changes such as shrinkage, membrane leakage, and cytoplasmic fragmentation prior to degeneration of oocytes. The NLE-treated oocytes that had morphologic apoptotic features showed overexpression of bax protein and DNA fragmentation as evidenced by terminal deoxynucleotidyl transferase nick-end labeling-positive staining and DNA ladder pattern. CONCLUSION(S) Neem leaf extract induced apoptosis in rat oocytes prior to degeneration in vitro.

Abstract
UNLABELLED Nonhormonal drugs for contraception in men may have advantages over hormonal methods. The nonhormonal methods can have more rapid onset and less interference with androgen-dependent functions. This systematic review summarizes the clinical studies evaluating nonhormonal drugs administered to men for contraception. Relevant clinical results were found for gossypol, which is derived from the cotton plant, and for extracts of Tripterygium, a plant used in Chinese traditional medicine. Randomized, controlled trials were available on the efficacy of gossypol and on the effect of gossypol on potassium levels. Gossypol had problems with low efficacy and toxicity. For Tripterygium, 2 observational studies described men who were treated for rheumatoid arthritis. Although sperm density was lower among those taking Tripterygium, later reports indicated some toxicity. Nonclinical research continues on isolates of Tripterygium. No clinical studies for contraception in men were found for nonhormonal vaccines or neem, which is also a plant used for medicinal purposes. Clinical trials studied injecting styrene maleic anhydride into the vas deferens, but no comparative data were provided. At this time, no safe and effective nonhormonal drug is available for contraception in men. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completion of this article, the reader should be able to state that the number of studies concerning the use of nonhormonal drugs for male contraception are very limited, point out that the two nonhormonal drugs used to a small degree have varying results and serious side effects, and recall that there are limited clinical studies on use of vas deferens injections and vaccines in humans.
