[PMID: 38896265 PMCID: PMC11319429 DOI: 10.1007/s00415-024-12436-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2024] [Revised: 05/08/2024] [Accepted: 05/09/2024] [Indexed: 06/21/2024]
Abstract
Valproate is the most effective medication for generalised epilepsies, and several specific epilepsy syndromes. For some people, it will be the only medication to establish seizure remission, and withdrawing it carries risks of seizure recurrence and Sudden Unexpected Death in Epilepsy (SUDEP). It is also of proven efficacy for bipolar disorder and migraine prevention. Guidelines based on observational and epidemiological studies stress that maternal valproate related teratogenicity and neurodevelopmental effects are significantly higher than for other antiseizure medications (ASMs). It should, therefore, only be used if other medications are ineffective and after balancing the teratogenicity risk. Regulatory restrictions have changed prescribing practices and reduced valproate use. The number of other medications that must be trialled in the different conditions for which valproate has effectiveness and the consequences of the lack of efficacy of those drugs leading to significant harm including death remains unexplored. Risk minimisation measures (RMMs) for valproate, chiefly Pregnancy Prevention practices (PPP), consider foetal risk and not risk to people living with epilepsy. In the United Kingdom (UK), limitations relating to valproate use in all people < 55 years commenced in January 2024. While the evidence in child-bearing women is not disputed, the data in males are based on animal models, case reports, and one commissioned, unpublished, non-peer reviewed report unavailable to the UK public, stakeholder charities or professionals. Evidence suggests that 30-40% of people switching from valproate have breakthrough seizures. Thus, an estimated 21,000-28000 people in the UK will imminently be exposed to the potential hazards of breakthrough seizures, including death. There is little government investment in monitoring the effects of these changes to valproate prescribing on patient health and quality of life. This review summarises the history of valproate regulation, evidence underpinning it and argues how the latest regulations in the UK do not align with the country's medical regulatory bodies ethical principles nor with the Montgomery principles of informed patient choice and autonomy. It dissects how such regulations infringe Common Law principles, nor give due regard for patient outcomes beyond reproduction. The paper looks to provide recommendations to redress these concerns while appreciating the core need for such governance to emerge in the first place.

Donepezil and quercetin alleviate valproate-induced testicular oxidative stress, inflammation and apoptosis: Imperative roles of AMPK/SIRT1/ PGC-1α and p38-MAPK/NF-κB/ IL-1β signaling cascades. Int Immunopharmacol 2024; 134:112240. [PMID: 38744177 DOI: 10.1016/j.intimp.2024.112240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 04/23/2024] [Accepted: 05/08/2024] [Indexed: 05/16/2024]
Abstract
The mounting evidence of valproate-induced testicular damage in clinical settings is alarming, especially for men taking valproate (VPA) for long-term or at high doses. Both donepezil (DON) and quercetin (QUE) have promising antioxidant, anti-inflammatory, and anti-apoptotic effects. Therefore, this study aimed to determine whether DON, QUE, and their combination could mitigate VPA-induced testicular toxicity and unravel the mechanisms underlying their protective effect. In this study, male albino rats were randomly categorized into six equal groups: control, VPA (500 mg/kg, I.P., for 14 days), DON (3 and 5 mg/kg), QUE (50 mg/kg), and DON 3 + QUE combination groups. The DON and QUE treatments were administered orally for 7 consecutive days before VPA administration and then concomitantly with VPA for 14 days. VPA administration disrupted testicular function by altering testicular architecture, ultrastructure, reducing sperm count, viability, and serum testosterone levels. Additionally, VPA triggered oxidative damage, inflammatory, and apoptotic processes and suppressed the AMPK/SIRT1/PGC-1α signaling cascade. Pretreatment with DON, QUE, and their combination significantly alleviated histological and ultrastructure damage caused by VPA and increased the serum testosterone level, sperm count, and viability. They also suppressed the oxidative stress by reducing testicular MDA content and elevating SOD activity. In addition, they reduced the inflammatory response by suppressing IL-1β level, NF-κB, and the p38-MAPK expression as well as inhibiting apoptosis by diminishing caspase-3 and increasing Bcl-2 expression. These novel protective effects were mediated by upregulating AMPK/SIRT1/PGC-1α signaling cascade. In conclusion, these findings suggest that DON, QUE, and their combination possess potent protective effects against VPA-induced testicular toxicity.

Abstract
The management of neurological disorders heavily relies on neurotherapeutic drugs, but notable concerns exist regarding their possible negative effects on reproductive health. Traditional preclinical models often fail to accurately predict reprotoxicity, highlighting the need for more physiologically relevant systems. Organoid models represent a promising approach for concurrently studying neurotoxicity and reprotoxicity, providing insights into the complex interplay between neurotherapeutic drugs and reproductive systems. Herein, we have examined the molecular mechanisms underlying neurotherapeutic drug-induced reprotoxicity and discussed experimental findings from case studies. Additionally, we explore the utility of organoid models in elucidating the reproductive complications of neurodrug exposure. Have discussed the principles of organoid models, highlighting their ability to recapitulate neurodevelopmental processes and simulate drug-induced toxicity in a controlled environment. Challenges and future perspectives in the field have been addressed with a focus on advancing organoid technologies to improve reprotoxicity assessment and enhance drug safety screening. This review underscores the importance of organoid models in unraveling the complex relationship between neurotherapeutic drugs and reproductive health.

The deleterious effects of sofosbuvir and ribavirin (antiviral drugs against hepatitis C virus) on different body systems in male albino rats regarding reproductive, hematological, biochemical, hepatic, and renal profiles and histopathological changes. Sci Rep 2024; 14:5682. [PMID: 38453980 PMCID: PMC10920821 DOI: 10.1038/s41598-024-55950-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2023] [Accepted: 02/29/2024] [Indexed: 03/09/2024] Open
Abstract
Sofosbuvir is one of the crucial drugs used in the treatment of chronic hepatitis C virus (HCV) in adults and children with compensated liver disease, including cirrhosis. It may be used alone or with other drugs. Ribavirin is an antiviral medication used to treat HCV infection. It is not effective when used alone and must be used in combination with other medications, such as sofosbuvir. This study pertains to a comprehensive assessment of the deleterious effects of sofosbuvir (an antiviral drug against chronic HCV) or sofosbuvir combined with ribavirin (an antiviral drug against RNA and DNA viruses) on several biological activities of the body, including hematological, hormonal, biochemical, histological, and immunohistochemical examinations during a long-standing period on male healthy rats. In addition, fertility assessments were performed, including sperm collections and semen parameter investigations. This study was conducted on 21 male rats divided into three equal groups. Group I (control group) received distilled water; group II (sofosbuvir group) received sofosbuvir (4 mg/kg); and group III (sofosbuvir + ribavirin) received sofosbuvir (4 mg/kg) plus ribavirin (30 ml/kg). All groups received the specific drug for six months. Blood and tissue samples were collected for hematological, hormonal, biochemical, histological, and immunohistochemical examinations. In addition, sperm collection and assessments of semen parameters were performed. Results revealed that sofosbuvir causes a highly significant decrease in the mean of most hematological, immunological, hormonal, and biochemical parameters, except for a few numbers of parameters such as neutrophils, monocytes, basophils, cortisol, GOT, and lipase, which exhibit a significant increase. The same occurred in the sofosbuvir + ribavirin group, but at much higher levels, as most hematological, immunological, hormonal, and biochemical parameters exhibit a highly significant decrease except for monocytes, triglyceride, and lipase, which exhibit a significant increase. When compared to the sofosbuvir group alone, the sofosbuvir + ribavirin group demonstrated a highly significant decline in the mean of most hematological, immunological, hormonal, and biochemical parameters except lymphocytes and triglycerides, which exhibit a substantial increase. For the reproductive parameters, both groups exhibit a significant decrease in the total sperm motility percentage. Finally, it can be concluded that sofosbuvir causes acute pancreatitis and combined immunodeficiency. Ribavirin is associated with hormonal deficiency, which indicates the occurrence of hypopituitarism. Moreover, sofosbuvir and ribavirin synergistically affect myelosuppression and cause iron-deficiency anemia. However, sofosbuvir, or its combination with ribavirin, is associated with a reduced risk of hepatocellular carcinoma. Besides, adding ribavirin to be combined with sofosbuvir improved the immunodeficiency caused by sofosbuvir; this confirms that using ribavirin with sofosbuvir reduces the side effects of both alone.

Abstract
OBJECTIVE Human exposure to multiple xenobiotics, over various developmental windows, results in adverse health effects arising from these concomitant exposures. Humans are widely exposed to bisphenol A, and acetaminophen is the most commonly used over-the-counter drug worldwide. Bisphenol A is a well-recognized male reproductive toxicant, and increasing evidence suggests that acetaminophen is also detrimental to the male reproductive system. The recent recognition of male reproductive system dysfunction in conditions of suboptimal reproductive outcomes makes it crucial to investigate the contributions of toxicant exposures to infertility and sub-fertility. We aimed to identify toxicity in the male reproductive system at the mitochondrial level in response to co-exposure to bisphenol A and acetaminophen, and we investigated whether melatonin ameliorated this toxicity. METHODS Male Wistar rats were divided into six groups (n=10 each): a control group and groups that received melatonin, bisphenol A, acetaminophen, bisphenol A and acetaminophen, and bisphenol A and acetaminophen with melatonin treatment. RESULTS Significantly higher lipid peroxidation was observed in the testicular mitochondria and sperm in the treatment groups than in the control group. Levels of glutathione and the activities of catalase, glutathione peroxidase, glutathione reductase, and manganese superoxide dismutase decreased significantly in response to the toxicant treatments. Likewise, the toxicant treatments significantly decreased the sperm count and motility, while significantly increasing sperm mortality. Melatonin mitigated the adverse effects of bisphenol A and acetaminophen. CONCLUSION Co-exposure to bisphenol A and acetaminophen elevated oxidative stress in the testicular mitochondria, and this effect was alleviated by melatonin.

Abstract
Background Monosodium glutamate (MSG) is a food ingredient that is increasingly used commercially. MSG leads to oxidative stress, consequently suppressing steroid hormone production that causes defects in male reproductive system. This study aimed to evaluate the effect of L-carnitine as an antioxidant on testicular damage in MSG-induced male rats. Methods Sixty adult male Spargue-Dawley rats were randomly divided into six groups of ten as follows: control (water), sham (normal saline), L-carnitine (200 mg/kg b.w), MSG (3 g/kg b.w), MSG + L-carnitine 100 (3 g/kg b.w of MSG and 100 mg/kg b.w of L-carnitine), and MSG + L-carnitine 200 (3 g/kg b.w of MSG and 200 mg/kg b.w of L-carnitine). The treatment was administered by oral gavage for six months. Serum levels of Malondialdehyde (MDA), Total Anti-oxidant Capacity (TAC), LH, FSH, testosterone, and mRNA expressions of Star, Cyp11a1, and Hsd17b3 genes, and histological and stereological changes were assessed. Results L-carnitine led to a significant decrease in the level of MDA and a significant rise in the serum levels of TAC, LH, FSH, and mRNA expression of Star and Cyp11a1 compared to the MSG group (p < 0.05). Furthermore, stereological results indicated a significant increment in the number of sexual lineage cells, the total volume of the testis, length, diameter, and volume of seminiferous tubules, the height of the germinal epithelium, sperm count, and sperm motility (p < 0.05) in MSG + L-carnitine 200 compare to MSG group. Conclusion The study’s findings demonstrated that L-carnitine due to its anti-oxidant properties, ameliorated the reproductive abnormalities in the male rats exposed to MSG.

Abstract
Valproic acid (VPA) is widely used antiepileptic agent which is associated with reproductive toxicity via impairment in oxidative redox. Zinc (Zn) and selenium (Se) are trace element with antioxidant effect that known to be essential for spermatogenesis. In the current study, the protective effect of co-administration of Zn and Se on VPA-induced reproductive toxicity in male rats was evaluated. Forty-eight male rats were divided into 8 groups of six (n=6): Control group (treated with normal saline); VPA only (250, 500, 1,000 mg/kg) group; VPA (500 mg/kg) plus Zn (2 mg/kg) group; VPA (500 mg/kg) plus Se (1.5 mg/kg) group; VPA (500 mg/kg) plus a combination of Zn and Se group; and VPA+vitamin E (20 mg/kg) group. The Animals were sacrificed after 28 days of treatment and sperm analysis was taken. Also, evaluation of oxidative stress markers including malondialdehyde (MDA), protein carbonyl (PC), glutathione (GSH) and histopathological changes were done on testis tissue. Morphological changes and a significant decrease in motility and sperm count in rats treated with VPA were observed. Also, an increase in oxidative stress marker, including MDA and PC and a decrease in GSH level was evident in VPA group. Zn and Se administration was able to protect against sperm abnormality, ameliorate the histological change in testis tissue, and suppressed the increase in oxidative stress markers induced by VPA. These results indicated that combination therapy with Zn and Se showed better an ameliorative effect than each one alone. Therefore, it can be suggested as an effective supplement for reproductive impairment in VPA-treated patient.

Abstract
Valproic acid (VPA) is a teratogenic antiepileptic, causing alterations in oxidative stress in prenatal development, being altered the development of the male reproductive system. The purpose of this study was to determine the protective effect of vitamin E (VE) on the testicular development in embryos, foetuses and pubertal mice exposed to VPA, VPA+VE and only VE. Sixty pregnant adult female mice were used, to which they were administered 600 mg/kg of VPA (VPA groups), 600 mg/kg of VPA and 200 IU of VE (VPA+VE groups), 200 IU VE (VE groups) and 0.3 ml of 0.9% physiological solution (control groups), showing at 12.5 days post-coital (dpc), 17.5 dpc and 6 weeks postnatal testicular development, and proliferative and apoptotic indices. The groups treated with VPA presented a smaller testicular volume, with greater interstitial space and a delay in the conformation of the testicular cords, shorter lengths and diameters of the germinal epithelium, a smaller number of germline and somatic cells, an increase in cells apoptotic and less proliferation, with significant differences. VE-treated groups behaved similarly to controls. In conclusion, VE reduces the effects caused by VPA throughout testicular development, from embryonic stages, continuing until pubertal stages.

[PMID: 34027381 PMCID: PMC8127004 DOI: 10.1016/j.ebr.2021.100446] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 02/11/2021] [Accepted: 02/12/2021] [Indexed: 11/29/2022] Open
Abstract
Sodium valproate is a broad spectrum anti-seizure medication useful in the treatment of both generalized and focal epilepsies. The association between valproate and female reproductive disorders is well understood and delineated. Male infertility however is an under-recognised adverse effect of Valproate therapy. Previous case reports have detailed reversible male infertility secondary to valproate. One report demonstrated a relationship between valproate dose and abnormal sperm parameters. We submit a case report suggesting a dose dependent effect of valproate on sperm parameters and a possible relationship between the duration of valproate therapy and its deleterious effect on male fertility. Men on valproate should be counselled about the possibility of progressive but reversible infertility. Valproate should be stopped and replaced by an alternative agent in those men who are infertile and where the couple are trying to conceive, particularly if there are associated abnormal sperm parameters while on the drug.

Carbamazepine adversely altered the pituitary-testicular axis with resultant reproductive dysfunctions than levetiracetam or carbamazepine-levetiracetam adjuvant treatment in male Wistar rat. Andrologia 2020; 52:e13871. [PMID: 33126292 DOI: 10.1111/and.13871] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/22/2020] [Revised: 09/06/2020] [Accepted: 09/16/2020] [Indexed: 12/12/2022] Open
Abstract
This study investigated the on-toward reactions of individual or adjunctive treatment with carbamazepine (CBZ) and levetiracetam (LEV) on the pituitary-testicular axis in male rats. Twenty-four male Wistar rats were randomised into 4 groups (n = 6) and received daily intraperitoneal (i.p) treatment of normal saline (0.1 ml/day); CBZ (25 mg/kg i.p); LEV (50 mg/kg i.p); or combination of CBZ (12.5 mg/kg) and LEV (25 mg/kg) for 4 weeks. The serum concentration of luteinising hormone (LH), follicle-stimulating hormone (FSH), and testosterone was determined. Also, the seminal profile and histomorphological status of the testis were determined. Data were analysed using descriptive and inferential statistics. The control and test groups were compared using Student's t test, analysis of variance (ANOVA), and Student-Newman-Keuls post hoc analysis where appropriate, while the results presented as mean ± SEM in graphs or tables. The level of significance was taken at p < .05. The percentage motility, viability, and concentration of FSH decreased significantly in all the treatment groups, while the testis was presented with various forms of histomorphological aberrations. This study concludes that CBZ, and CBZ + LEV adjunctive treatments alter the pituitary-testicular axis with evidence of hormonal deregulation and alteration in the reproductive functions' indices, while LEV treatment remains the safest.

[DOI: 10.2174/1381612826666201029101524] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2020] [Accepted: 09/22/2020] [Indexed: 11/22/2022]
Abstract
Background:
Oxandrolone is a synthetic testosterone analogue that is widely used among bodybuilders and
athletes. However, oxandrolone causes male infertility. Recently, it was found that metformin reduces the risk of infertility
associated with diabetes mellitus.
Aim:
This study aimed to investigate the protective effects of metformin against oxandrolone-induced infertility in male
rats.
Methods:
Rats continuously received one of four treatments (n=7) over 14 days: control DMSO administration, oxandrolone
administration, metformin administration, or co-administration of oxandrolone and metformin. Doses were equivalent to
those used for human treatment. Subsequently, testicular and blood samples were collected for morphological, biochemical,
and histological examination. In addition, gene expression of the testosterone synthesizing enzyme CYP11A1 was analyzed
in the testes using RT-PCR.
Results:
Oxandrolone administration induced male infertility by significantly reducing relative weights of testes by 48%,
sperm count by 82%, and serum testosterone levels by 96% (ANOVA, P value < 0.05). In addition, histological examination
determined that oxandrolone caused spermatogenic arrest which was associated with 2-fold downregulation of testicular
CYP11A1 gene expression. However, co-administration of metformin with oxandrolone significantly ameliorated
toxicological alterations induced by oxandrolone exposure (ANOVA, P value < 0.05).
Conclusion:
Metformin administration protected against oxandrolone-induced infertility in male rats. Further clinical
studies are needed to confirm the protective effect of metformin against oxandrolone-induced infertility among athletes.

Watkins LV, Angus-Leppan H. Valproate, sexual health, and men: A narrative review. Epilepsy Behav 2020; 103:106835.

Abstract
OBJECTIVE This article explores current evidence about the effects of valproate (VPA) medicines on sexual health in men, how to monitor symptoms, communicate with patients, and improve clinical outcomes. There has been a lot of focus on VPA use in women of childbearing age following recent changes to prescribing regulations owing to the well-established and significant teratogenic risk. Concerns have been raised by patients and clinicians as to the risk of adverse sexual effects of VPA use in men. RESULTS The evidence base for the effect of VPA on sexual function compared with other antiepileptic drugs (AEDs) in men is limited with no randomized controlled trials. Sexual function in men with epilepsy is complex, and there is no direct relationship between objective measures of sexual function and sexual satisfaction. Epilepsy, comorbidities, psychosocial factors, and most AEDs including VPA may cause sexual dysfunction in men, including reduced sexual desire, erectile dysfunction, and fertility problems. Sexual and reproductive function should be discussed with men prior to treatment with AEDs including VPA. CONCLUSION Early and proactive discussion of sexual and reproductive functioning mitigates, rather than increases, the risk of sexual problems and potentially improves adherence. Sexual dysfunction in men with cognitive impairment [such as intellectual disability (ID) and dementia] may present with behavioral disturbance. Identification of sexual adverse effects of medication could significantly change treatment plans which is of particular importance for individuals with treatment resistance. We provide an information fact sheet for men to help guide prescribing discussions.

Abstract
Dapsone (4, 4'-diaminodiphenylsulfone, DDS) is a potent anti-inflammatory and antibacterial compound which has been used in the treatment of leprosy, vasculitis and dermatitis herpetiformis, lupus erythematosus profundus and even as an antimalarial in combination with proguanil. This study investigated the effect of the administration of dapsone on the reproductive activities of male rats using in vivo and in vitro techniques. In the in vivo study, dapsone was administered orally to male Wistar rats for 5 days or 6 weeks after which their body weight, relative reproductive organ weights, sperm parameters and reproductive hormones were determined while testicular and epididymal histology were also assessed. Data were compared using analysis of variance and Students-Newman-Keuls multiple comparison test. For the in vitro study, Sertoli cells were cultured and treated with varying doses of dapsone at different durations, thereafter Sertoli cell viability and nuclei integrity were determined. Also, the genetic expressions of Glial cell line-derived neurotrophic factor (GDNF) and transferrin were assessed. The results obtained from the in vivo study showed a duration-dependent significant decrease in body and reproductive organ weights, sperm parameters and serum testosterone concentration. Testicular and epididymal histology also showed duration-dependent degenerative changes. However, all these changes were restored towards control values in the recovery experiment. The viability and deoxyribonucleic acid (DNA) integrity of the treated Sertoli cells showed dose and duration-dependent adverse effects while GDNF and transferrin showed normal genetic expressions. These results suggest that dapsone could induce male reproductive stress by affecting testicular and epididymal structure and function.

Abstract
Epigenetic modifications, including DNA methylation and histone modifications, determine the way DNA is packaged within the nucleus and regulate cell-specific gene expression. The heritability of these modifications provides a memory of cell identity and function. Common dysregulation of epigenetic modifications in cancer has driven substantial interest in the development of epigenetic modifying drugs. Although these drugs have the potential to be highly beneficial for patients, they act systemically and may have “off-target” effects in other cells such as the patients’ sperm or eggs. This review discusses the potential for epigenomic drugs to impact on the germline epigenome and subsequent offspring and aims to foster further examination into the possible effects of these drugs on gametes. Ultimately, the information gained by further research may improve the clinical guidelines for the use of such drugs in patients of reproductive age.

Abstract
BACKGROUND Valproic acid (VPA), an anti-epileptic drug, can cause male subfertility. However, the degree to which testicular and epididymal histopathologies and androgen receptor (AR) expression are changed under VPA treatment has never been reported. OBJECTIVE To investigate the histopathological changes and AR protein levels of testis and epididymis in VPA-treated rats for every single day. MATERIALS AND METHODS Sixty-four adult male Wistar rats were divided into control and VPA-treated groups (n=8/ each). Treated rats were injected with 500 mg/ kgBW, intraperitoneally, VPA for 10 consecutive days. At the end of every experimental day, all reproductive parameters including histology by hematoxylin and eosin staining and protein expression of AR by Immuno-Western blot in testis and epididymis were examined. RESULTS VPA-treated rats showed dramatically changes in testicular and epididymal histopathologies compared to control group. The multinucleated giant cells and sloughing of germ cells were observed on day 6. The germ cell disintegration and increased intercellular spaces of seminiferous tubular epithelium appeared in days 7-10 of VPA treatment. Additionally, extensive multinucleated giant cells and complete exfoliation were clearly found from days 8-10. Such exfoliated germ cells were clearly seen in its epididymal lumen at day 10. The increasing rate of sperm concentration was approximately 32.31% of that in control group at day 10 (p=0.03). Moreover, the protein expressions of testicular and epididymal AR (% intensity/ 80 µg protein lysate) was decreased in VPA-treated rats compared with control. CONCLUSION VPA treatment induces histologic changes of germ cell epithelium in seminiferous tubules and decreases the expression of testicular and epididymal androgen receptors.

Abstract
Valproic acid (VPA), an anti-epileptic drug, reduces testosterone levels and sperm quality. However, the degree to which testosterone levels and sperm quality are decreased under VPA treatment needs to be clarified. The aim of the present study was to investigate the testicular proteins involved in testosterone synthesis and spermatogenesis, histopathology and sperm acrosome status in VPA-treated rats. Adult rats were divided into control and experimental groups (n = 8 in each). Rats in the experimental group were treated with 500 mg kg–1, i.p., VPA for 10 consecutive days. Expression of Ki-67, tyrosine phosphorylated proteins and testicular steroidogenic proteins was examined. As expected, VPA-treated rats exhibited adverse changes in almost all reproductive parameters, particularly an increase in precocious acrosome reactions, compared with the control group. In addition, fibrosis of the tunica albuginea and tubule basement membrane was observed in testes from VPA-treated rats. Moreover, the expression of testicular Ki-67, cholesterol side-chain cleavage enzyme (P450scc) and phosphorylated proteins (41, 51 and 83 kDa) was decreased significantly in VPA-treated rats compared with control. In contrast, the expression of steroidogenic acute regulatory proteins in the VPA-treated group was significantly higher than in the control group. In conclusion, VPA treatment changes the expression of testicular proteins responsible for spermatogenesis and testosterone production, resulting in male infertility.

Abstract
Psychotropic drugs, including antidepressants, antipsychotics, and anticonvulsants, all have negative effects on sexual function and semen quality. These adverse events vary among men and are less pronounced for some medications, allowing their effects to be managed to some extent. Use of specific serotonin reuptake inhibitors (SSRIs) is prevalent in men of reproductive age; and application to treat premature ejaculation increases the number of young men on SSRI therapy. Oxidative damage to sperm can result from prolonged residence in the male reproductive tract. The increase in ejaculatory latency seen with SSRIs likely underlies some of their negative effects on semen quality, including higher sperm DNA fragmentation, seen in all SSRIs evaluated thus far. These medications increase prolactin (PRL) levels in some men, and this is often credited with inhibitory effects on male reproduction; however, testosterone levels are generally normal, reducing the likelihood of direct HPG axis inhibition by PRL. The tricyclic antidepressants have also been shown to increase PRL levels in some studies but not in others. The exception is the tricyclic antidepressant clomipramine, which profoundly increases PRL levels and may depress semen quality. Other antidepressants modulating synaptic levels of serotonin, norepinephrine, and/or dopamine may have toxicity similar to SSRIs, but most have not been evaluated. In limited studies, norepinephrine-dopamine reuptake inhibitors (NDRIs) and serotonin agonist/reuptake inhibitors (SARIs) have had minimal effects on PRL levels and on sexual side effects. Antipsychotic medications increase PRL, decrease testosterone, and increase sexual side effects, including ejaculatory dysfunction. The greatest evidence is for chlorpromazine, haloperidol, reserpine, risperidone, and thioridazine, with less effects seen with aripiprazole and clozapine. Remarkably few studies have looked at antipsychotic effects on semen quality, and this is an important knowledge gap in reproductive pharmacology. Lithium increases PRL and LH levels and decreases testosterone although this is informed by few studies. The anticonvulsants, many used for other indications, generally decrease free or bioavailable testosterone with variable effects on the other reproductive hormones. Valproate, carbamazepine, oxcarbazepine, and levetiracetam decrease semen quality; other anticonvulsants have not been investigated for this adverse reaction. Studies are required evaluating endpoints of pregnancy and offspring health for psychotropic medications.

Abstract
OBJECTIVE To explore the antispermatogenic and testicular antisteroidogenic activities of Feronia limonia fruit pulp southern India. METHODS Fourty Wistar male albino rats (Rattus norvegicus) were equally divided into four groups. Experimental groups were administered with the ethanolic extract of Feronia limonia (F. limoni) fruit pulp at doses of 250 and 500 mg/kg body weight once daily for 55 days. All treated rats had corresponding recovery groups. At the end of each treatment periods, various spermatological indices, tissue biochemicals and testicular enzymes levels were analysed. Blood profiles were also estimated. RESULTS Compared with the control, the F. limonia fruit pulp at both dose levels did not decrease body weight, which were associated with decline in epididymal sperm count, motility, viability and increased percent of abnormal sperm. Further, F. limonia fruit pulp at 500 mg/kg body weight markedly reduced the epididymal and testicular protein content by 24.58% and 29.86%, respectively, as well as the glucose-6-phosphate dehydrogenase and Δ(5)-3β-hydroxy steroid dehydrogenase) levels by 42.82% and 38.08%, respectively, while a significant elevation was observed in testicular cholesterol and ascorbic acid content. A gradual recovery of all parameters was observed after 55 days of treatment withdrawal. No significant alterations in haematological indices were observed. CONCLUSIONS The present findings indicate that F. limonia fruit pulp may have reversible antispermatogenic and antisteroidogenic properties, and could partially support the traditional use as male contraceptive.

Abstract
BACKGROUND The potential toxicity resulting from the possible interactions of the herbicides, Ultrazin (atrazine, ATZ) and Bretmont Wipeout (glyphosate, GLY) (as commercialized in Nigeria), is not completely known. We therefore evaluated reproductive- and hepato-toxicity in rats co-exposed to ATZ and GLY. METHODS Six weeks old male rats were exposed by gavage three times per week to ATZ (12.5 mg/kg) or GLY (5 mg/kg) alone or in combination (12.5 mg/kg ATZ + 5 mg/kg GLY) or vehicle (corn oil), for 52 days. RESULTS ATZ and GLY impaired sperm quality but GLY has more adverse effect on sperm quality than ATZ. Testosterone level, sperm motility, sperm counts, live/dead ratio and the weight of the epididymis were lower in the GLY group compared to the ATZ group by 57%, 33%, 20%, 22% and 41% and higher by 109%, 76.7%, 39.6%, 32.3% and 100% respectively in the combine-exposure group (ATZ + GLY) compared to the GLY group. Oxidative stress and histopathological changes were also noticeable in the liver but not in the testis of GLY-treated animals, and the observed effects were more remarkable in the GLY group than the ATZ or the combined-exposure group. The combined effects of the active ingredients on testosterone level, sperm count and hepatic malondialdehyde (MDA) levels were also similar as when the commercial formulations were used. CONCLUSION There are therefore antagonistic interactions between the two toxicants on the toxicity endpoints investigated in this study and these effects are due to the active ingredients of both herbicides in the commercial formulations.

[PMID: 25276476 PMCID: PMC4178192 DOI: 10.5115/acb.2014.47.3.171] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2014] [Revised: 07/20/2014] [Accepted: 07/24/2014] [Indexed: 11/27/2022] Open
Abstract
The present study investigated the cytogenetic and testicular damage induced by the antiepileptic drug, sodium valporate (SVP) in albino rats and the effect of saffron aqueous extracts. Treating rats with SVP caused a significant increase in the chromosomal aberrations either structural or numerical and decreased the mitotic index. Besides, animals administered SVP showed DNA damage appeared in the single strand breaks (comet assay). Testis of SVP-treated rats showed many histopathological changes. A significant decrease in seminiferous tubules and their epithelial heights diameters and inhibition of spermatogenesis was recorded. In addition, the number of sperm head abnormalities was increased. Biochemical results revealed an increase in malondialdhyde (MDA) which is lipid peroxidation marker and a significant decrease in the level of serum antioxidant enzyme, catalase (CAT) and reducing antioxidant power (RAP). Animals given SVP and saffron showed an improvement in chromosomal aberrations, mitotic index, DNA damage and testicular alterations caused by SVP. Moreover, MDA decreased and CAT and RAP increased. It is concluded from the present results that the ameliorative effects of saffron extract against SVP-induced cytogenetic and testicular damage in albino rats may be due to the presence of one or more antioxidant components of saffron.

Shalaby MA, Hammouda AAEK. Assessment of protective and anti-oxidant properties of Tribulus terrestris fruits against testicular toxicity in rats. JOURNAL OF COMPLEMENTARY MEDICINE RESEARCH 2014; 3:113-8. [PMID: 26401358 PMCID: PMC4566674 DOI: 10.5455/jice.20140627123443] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2014] [Accepted: 06/27/2014] [Indexed: 01/23/2023]
Abstract
AIMS This study was carried out to assess the protective and anti-oxidant activities of the methanolic extract of Tribulus terrestris fruits (METT) against sodium valproate (SVP)-induced testicular toxicity in rats. MATERIALS AND METHODS Fifty mature male rats were randomly divided into five equal groups (n = 10). Group 1 was used normal (negative) control, and the other four groups were intoxicated with SVP (500 mg/kg(-1), orally) during the last week of the experiment. Group 2 was kept intoxicated (positive) control, and Groups 3, 4 and 5 were orally pre-treated with METT in daily doses 2.5, 5.0, and 10.0 mg/kg(-1) for 60 days, respectively. Weights of sexual organs, serum testosterone, follicle stimulating hormone (FSH) and luteinizing hormone (LH) levels, semen picture, testicular anti-oxidant capacity and histopathology of testes were the parameters used in this study. RESULTS Oral pre-treatment with METT significantly increased weights of testes and seminal vesicles; serum testosterone, FSH and LH levels and sperm motility, count and viability in SVP-intoxicated rats. METT enhanced the activity of testicular anti-oxidant enzymes and partially alleviated degenerative changes induced by SVP in testes. CONCLUSION The pre-treatment with METT has protective and anti-oxidant effects in SVP-intoxicated rats. Mechanisms of this protective effect against testicular toxicity may be due to the increased release of testosterone, FSH and LH and the enhanced tissue anti-oxidant capacity. These results affirm the traditional use of T. terrestris fruits as an aphrodisiac for treating male sexual impotency and erectile dysfunction in patients. The study recommends that T. terrestris fruits may be beneficial for male patients suffering from infertility.

Dhanapal R, Ratna JV, Gupta M, Sarathchandran I. Preliminary study on antifertility activity of Enicostemma axillare leaves and Urena lobata root used in Indian traditional folk medicine. ASIAN PAC J TROP MED 2012; 5:616-22. [PMID: 22840449 DOI: 10.1016/s1995-7645(12)60127-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2012] [Revised: 03/15/2012] [Accepted: 05/15/2012] [Indexed: 10/28/2022] Open
Abstract
OBJECTIVE To evaluate the possible antifertility activity of Enicostemma axillare (E. axillare) leaves and Urena lobata (U. lobata) root in adult male Wistar albino rats. METHODS Six groups of rats were treated with ethanolic (70%v/v) extracts of E. axillare (375 and 750 mg/kg body weight) and U. lobata root (300 and 600 mg/kg body weight) once daily for 55 days. Control groups received the distilled water and vehicle. All the treated rats had corresponding recovery groups. At the end of each treatment periods, animals were killed and organ weights, sperm characteristics, testicular and epididymal biochemicals as well as testicular enzymes were assessed. RESULTS The E. axillare and U. lobata at tested doses did not decrease body weight, whereas the weight of testes, epididymides and seminal vesicles were significantly (P<0.01) reduced. Significantly (P<0.01) more reductions in the sperm motility, viability and counts, epididymal and testicular protein contents were noted in the rats treated with higher dose of both the plants. Both the plants at the higher dose caused a marked increase (P<0.01) in sperm morphological abnormalities, testicular cholesterol and ascorbic acid contents were remarkably increased (P<0.01), while, the activities of testicular glucose-6-phosphate dehydrogenase (G-6-PDH) and Δ(5)-3β-hydroxy steroid dehydrogenase (Δ(5)-3β-HSD) were significantly reduced (P<0.01). However, reversal of these changes occurred after 55 days of treatment withdrawal. CONCLUSIONS This study suggests that the E. axillare leaves and U. lobata root reversibly inhibited spermatogenesis and steroidogenesis indicating reversible antifertility activity which could partially support the traditional of these plants as male contraceptives.
