[Disseminated tuberculosis revealed by epididymal localization in an immunocompetent patient: a case report]. / Tuberculose disséminée révélée par une localisation épididymaire chez un patient immunocompétent: à propos d'un cas.

Epididymal tuberculosis is rare and often presents diagnostic difficulties. It may be indicative of a disseminated form of the infection, which is the case of our patient. A 19-year-old man, with no past medical history, was admitted for a swollen painful left scrotum that had been evolving for 8 months. He had undergone an orchiectomy and the anatomopathological examination was consistent with epididymal tuberculosis. The radiological investigations had revealed other localizations of the infection: lymphatic, pulmonary, parietal and osteoarticular tuberculosis. Anti-tuberculosis therapy was introduced. However, in the 4th month of treatment, the patient developed seizures. A cerebral magnetic resonance imaging was practiced, concluding to cerebral tuberculomas. Anti-tuberculosis treatment was continued associated to an anticonvulsant with a favourable outcome. The originality of our observation resides in the mode of revelation of a disseminated paucisymptomatic tuberculosis, by an epididymal localization, in an immunocompetent patient.

Ursolic acid attenuates oligospermia in busulfan-induced mice by promoting motor proteins.

Background: Oligospermia is one of the most common reasons for male infertility which is troubling numerous couples of child-bearing age. This investigation scrutinizes the implications and mechanistic underpinnings of ursolic acid's effect on busulfan-induced oligospermia in mouse models. Methods: A singular intraperitoneal injection of busulfan at a dosage of 30 mg/kg induced oligospermia. Two weeks subsequent to this induction, mice were subjected to various dosages of ursolic acid (10, 30, and 50 mg/kg body weight, respectively) on a daily basis for four consecutive weeks. Following this treatment period, a meticulous analysis of epididymal sperm parameters, encompassing concentration and motility, was conducted using a computer-assisted sperm analysis system. The histopathology of the mice testes was performed utilizing hematoxylin and eosin staining, and the cytoskeleton regeneration of the testicular tissues was analyzed via immunofluorescent staining. Serum hormone levels, including testosterone, luteinizing hormone, and follicle-stimulating hormone, as well as reactive oxygen species levels (inclusive of reactive oxygen species and malondialdehyde), were gauged employing specific enzyme-linked immunosorbent assay kits. Differentially expressed genes of testicular mRNA between the oligospermia-induced group and the various ursolic acid treatment groups were identified through RNA sequencing analysis. Results: The results revealed that a dosage of 50 mg/kg ursolic acid treatment could increase the concentration of epididymal sperm in oligospermia mice, promote the recovery of testicular morphology, regulate hormone levels and ameliorate oxidative damage. The mechanism research results indicated that ursolic acid increased the expression level of genes related to motor proteins in oligospermia mice.

Effect of Spag11a gene knockout on the epididymis in mice: A histopathological and molecular analyses.

The sperm-associated antigen 11a (Spag11a) gene is exclusively expressed in the caput epididymis. Our previous studies demonstrated that small interfering RNA (siRNA)-mediated ablation of this gene resulted in increased proliferation of epididymal epithelial cells. Further, active immunization-mediated ablation of SPAG11A protein increased the susceptibility of male reproductive tract tissues to diethylnitrosamine (DEN)-induced tumorigenesis. In this study, we report that the caput epididymis of Spag11a knockout mice displayed hyperplasia and inflammation, while the caput epididymis of wild-type mice exhibited normal anatomical structure. Global transcriptome analyses in the caput epididymis of knockout mice indicated differential expression of genes involved in a variety of cellular processes. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses suggested that the absence of Spag11a may activate microRNAs associated with cancer, chemical carcinogenesis-receptor activation, and chemical carcinogenesis-DNA adducts pathways; which may contribute to the promotion of tumorigenesis in the epididymis. The susceptibility of caput epididymis to chemically induced carcinogenesis in Spag11a knockout mice was analyzed. Histological analyses indicated that while the epididymis of wild-type mice did not show any signs of tumorigenesis, knockout mice displayed hyperplasia, anaplasia, dysplasia, neoplasia, and inflammation in the caput epididymis. Our results provide concrete evidence that deletion of Spag11a induces histopathological and molecular changes that contribute to tumorigenesis. It is possible that the expression of Spag11a gene could be one of the reasons for the rarity of epididymal cancers. The involvement of an epididymal gene in tumorigenesis is being demonstrated for the first time.

A new nomogram based on ultrasound and clinical features for distinguishing epididymal tuberculosis and nontuberculous epididymitis.

Using ultrasound findings and clinical characteristics, we constructed and validated a new nomogram for distinguishing epididymal tuberculosis from nontuberculous epididymitis, both of which share similar symptoms. We retrospectively examined data of patients with epididymal tuberculosis and nontuberculous epididymitis hospitalized between January 1, 2013, and March 31, 2023. Eligible patients were randomly assigned to derivation and validation cohorts (ratio, 7:3). We drew a nomogram to construct a diagnostic model through multivariate logistic regression and visualize the model. We used concordance index, calibration plots, and decision curve analysis to assess the discrimination, calibration, and clinical usefulness of the nomogram, respectively. In this study, 136 participants had epididymal tuberculosis and 79 had nontuberculous epididymitis. Five variables-C-reactive protein level, elevated scrotal skin temperature, nodular lesion, chronic infection, and scrotal skin ulceration-were significant and used to construct the nomogram. Concordance indices of the derivation and validation cohorts were 0.95 and 0.96, respectively (95% confidence intervals, 0.91-0.98 and 0.92-1.00, respectively). Decision curve analysis of this nomogram revealed that it helped differentiate epididymal tuberculosis from nontuberculous epididymitis. This nomogram may help clinicians distinguish between epididymal tuberculosis and nontuberculous epididymitis, thereby increasing diagnosis accuracy.

Primary leiomyosarcoma of epididymis: a case report.

BACKGROUND: Leiomyosarcoma is a tumor that can develop in any organ that contains smooth muscles. Although leiomyosarcoma is common, its epididymal localization is quite rare. CASE PRESENTATION: A 79-year-old male Chinese Han patient presented with mild pain in the right groin and scrotum for 3 years concomitant with right scrotal swelling. Ultrasonography and magnetic resonance imaging of the scrotum showed a irregular and heterogeneous mass that was extratesticular. Right high orchiectomy was performed, and pathological examination of the resected specimen confirmed the diagnosis of leiomyosarcoma of the epididymis with surgical margins clear of tumor. CONCLUSION: Epididymal leiomyosarcoma is rare and difficult to diagnose preoperatively. The final diagnosis of epididymal leiomyosarcoma requires histologic examination. Resection must be extensive and complete. The effect of chemotherapy and radiation on the epididymal leiomyosarcoma remains unclear. Recurrence is common, so follow-up is necessary.

Immunodeviation towards T cell-mediated immune response in the testes of LPS-induced mouse epididymo-orchitis.

The testicular consequences of acute epididymo-orchitis remain largely unelucidated in long-term damage, which might be a neglected factor for male infertility. In this study, the differential phenotype of testicular immune cell subpopulations in lipopolysaccharide (LPS)-induced mouse epididymo-orchitis were analyzed by flow cytometry on day 1, day 7, and day 28. The number of macrophages, neutrophils, and myeloid-derived suppressor cells (MDSCs) steadily decreased in the testes with inoculation. Total F4/80-CD11c+ dendritic cells (DCs) maintained a relatively stable level, whereas conventional type 1 dendritic cells (cDC1) increased gradually from day 1 to day 28. There was a lower number of CD4+ and CD8+ T cells at day 1 and day 7, and they had similar results with a ceiling level at day 28. The testes displayed a higher level of CD3+ T cells but a lower frequency of macrophages, cDC2, and neutrophils at 28 days post-inoculation compared with the epididymis. In summary, our data indicates acute epididymo-orchitis could lead to long-term damage in the testes, which is characterized by CD3+ T cell (including CD4+ and CD8+ T cells)-mediated immune responses.

Treatment of primary epididymal adenocarcinoma: a case report and review of the literature.

BACKGROUND: Epididymal tumors, especially malignant tumors, have low incidence and are rare in our clinical work. However, they may progress quickly and have poor prognosis. For such rare clinical cases with extremely low incidence rates, and as they are prone to misdiagnosis and missed diagnosis and have a very poor prognosis, clinical workers need to pay special attention and consider the possibility of primary epididymal malignant tumors. CASE REPORT: A 63-year-old Chinese male patient from Asia was admitted due to scrotal pain. Upon examination, an abnormal lesion was found in the right epididymal region. After thorough evaluation, surgical resection was performed, and the postoperative pathological result confirmed the presence of epididymal adenocarcinoma. After further ruling out secondary lesions, primary epididymal adenocarcinoma was considered. Right retroperitoneal lymph node dissection was performed under laparoscopic for treatment, and 1/11 lymph node metastasis was detected after surgery. The patient is currently under close follow-up. CONCLUSIONS: The number of clinical cases of primary epididymal malignant tumors is very limited, there is currently no standardized diagnosis and treatment process, and there is a lack of systematic evaluation methods regarding the effectiveness of different treatment options such as chemotherapy, radiotherapy, immunotherapy, and targeted therapy. In addition, the outcome is difficult to predict. In this article, we reviewed relevant literature and systematically elaborated on the diagnosis and treatment of epididymal malignant tumors, hoping to provide useful information for relevant experts.

Retinoic acid mitigates the NSC319726-induced spermatogenesis dysfunction through cuproptosis-independent mechanisms.

Copper ionophore NSC319726 has attracted researchers' attention in treating diseases, particularly cancers. However, its potential effects on male reproduction during medication are unclear. This study aimed to determine whether NSC319726 exposure affected the male reproductive system. The reproductive toxicity of NSC319726 was evaluated in male mice following a continuous exposure period of 5 weeks. The result showed that NSC319726 exposure caused testis index reduction, spermatogenesis dysfunction, and architectural damage in the testis and epididymis. The exposure interfered with spermatogonia proliferation, meiosis initiation, sperm count, and sperm morphology. The exposure also disturbed androgen synthesis and blood testis barrier integrity. NSC319726 treatment could elevate the copper ions in the testis to induce cuproptosis in the testis. Copper chelator rescued the elevated copper ions in the testis and partly restored the spermatogenesis dysfunction caused by NSC319726. NSC319726 treatment also decreased the level of retinol dehydrogenase 10 (RDH10), thereby inhibiting the conversion of retinol to retinoic acid, causing the inability to initiate meiosis. Retinoic acid treatment could rescue the meiotic initiation and spermatogenesis while not affecting the intracellular copper ion levels. The study provided an insight into the bio-safety of NSC319726. Retinoic acid could be a potential therapy for spermatogenesis impairment in patients undergoing treatment with NSC319726.

Tetrabromobisphenol A reduces male rats reproductive organ coefficients and disrupting sexual hormone by causing oxidative stress.

Tetrabromobisphenol A (TBBPA) has become a topic of public attention due to its pervasive detection in the environment and organisms in recent decades. However, limited information is available regarding the toxicity of TBBPA on reproductive ability of male mammals. Herein, the reproductive toxicity of TBBPA was investigated in male rats to fill the knowledge gap. In this study, male rats were exposed to TBBPA (0, 10, 100, and 1000 mg/kg) for 6 weeks. Subsequently, body and organ indexes, histopathological evaluation of testis and epididymis, ultrastructural observation of sperm, testosterone and progesterone levels, and oxidative stress indicators were conducted to reveal corresponding mechanisms. Results obtained showed that compare to the control group, the body weight, testes weight, epididymis weight, seminal vesicle and coagulation glands weight of rats in the 1000 mg/kg group lost 8.30%, 16.84%, 20.16%, 19.72% and 26.42%, respectively. Intriguingly, exposure to TBBPA (10, 100, 100 mg/kg) resulted in substantial pathological damage in testis, epididymis and sperm. TBBPA exposure also increased malondialdehyde (MDA) and hydrogen peroxide (H2O2) contents, as well as superoxide dismutase (T-SOD) and catalase (CAT) activities in testicular tissue. What's more, the testosterone and progesterone levels in male rat serum were significantly decreased after exposure to TBBPA for 6 weeks. Meanwhile, results of molecular docking showed that TBBPA has a strong affinity with estrogen receptors (ERs). These findings demonstrated that TBBPA exposure negatively impacts the reproductive ability of male rats, thus providing new insights for risk assessment for reproductive health under TBBPA exposure.

Moment of induction and duration of experimental varicocele in rats: effects on semen quality.

PURPOSE: Varicocele is a condition known to cause damage to seminal parameters and sperm function. Furthermore, it has been hypothesized that the varicocele effect on fertility is time-dependent; however, little is known about the consequences of its establishment time on reproductive organs and/or sperm function. This study aimed to evaluate the effect of the duration of experimental varicocele on reproductive organs, sperm parameters, and sperm function. MATERIALS AND METHODS: Varicocele induction surgeries were performed in Wistar rats aged 40 or 100 days old. At 160-day-old, analyses were performed, including biometry of reproductive organs (prostate, seminal vesicles, epididymis, and testis), sperm parameters (vitality, morphology, and motility), and sperm function tests (nuclear DNA integrity, acrosome integrity, and mitochondrial activity). RESULTS: The analysis of the biometry of reproductive organs showed no differences between distinct ages in which varicocele was induced. The total abnormal sperm morphology was bigger in animals with varicocele induced to 100 days old than in animals with varicocele induced to 40 days old. Regarding nuclear DNA integrity, animals of varicocele induced to 100 days old showed worse results compared to animals of varicocele induced to 40 days old. Other parameters analyzed showed no differences between varicocele groups. CONCLUSION: In this study conducted on rats, we conclude that varicocele adversely affects sperm, particularly its function. However, we did not observe a negative progressive effect on sperm.

Long-term glucocorticoid infusion impairs epididymal adipocyte metabolism and maturation and affects miR-150-5p actions.

The most common form of hypercortisolism is iatrogenic Cushing's syndrome. Lipodystrophy and metabolic disorders can result from the use of exogenous glucocorticoids (GC). Adipocytes play an important role in the production of circulating exosomal microRNAs, and knockdown of Dicer promotes lipodystrophy. The aim of this study is to investigate the effect of GCs on epididymal fat and to assess their influence on circulating microRNAs associated with fat turnover. The data indicate that despite the reduction in adipocyte volume due to increased lipolysis and apoptosis, there is no difference in tissue mass, suggesting that epididymal fat pad, related to animal size, is not affected by GC treatment. Although high concentrations of GC have no direct effect on epididymal microRNA-150-5p expression, GC can induce epididymal adipocyte uptake of microRNA-150-5p, which regulates transcription factor Ppar gamma during adipocyte maturation. In addition, GC treatment increased lipolysis and decreased glucose-derived lipid and glycerol incorporation. In conclusion, the similar control and GC epididymal fat mass results from increased dense fibrogenic tissue and decreased adipocyte volume induced by the lipolytic effect of GC. These findings demonstrate the complexity of epididymal fat. They also highlight how this disease alters fat distribution. This study is the first in a series published by our laboratory showing the detailed mechanism of adipocyte turnover in this disease.

Impact of carbimazole combined with vitamin E on testicular injury induced by experimental hyperthyroidism in adult albino rats: oxidative/inflammatory/apoptotic pathways.

Thyroid hormones play essential roles in spermatogenesis, but their effects on infertile males remain poorly understood. This study aimed to evaluate the impact of combining carbimazole (CBZ) with vitamin E (VE) on testicular injury induced by experimental hyperthyroidism in adult albino rats, focusing on oxidative, inflammatory, and apoptotic pathways. In this experimental study, 64 adult male albino Wistar rats were divided into eight groups: Group I (control-untreated), Group II (CBZ-control), Group III (VE-control), Group IV (CBZ + VE-control), Group V (levothyroxine-induced testicular injury), Group VI (levothyroxine + CBZ-treated), Group VII (levothyroxine + VE-treated), and Group VIII (levothyroxine + CBZ + VE-treated). The study was conducted in the Faculty of Medicine, Suez Canal University (Ismailia, Egypt). After cervical decapitation, both testes and epididymis were examined histopathologically and immunohistochemically. Significant differences were observed among groups concerning malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT; all P < 0.001). Polymerase chain reaction analysis showed significant differences in tumor necrosis factor-α (TNF- α ), interleukin-10 (IL-10), Bcl-2-associated X protein (BAX), B-cell lymphoma 2 protein (Bcl2), p53, Caspase-3, Caspase-8, Caspase-9, and nuclear factor-kappa B (NF- κ B) mRNA levels (all P < 0.001). Hyperthyroid group treated with CBZ alone (Group VI) exhibited testicular side effects, affecting seminiferous tubules and spermatogenesis. However, the Group VIII showed improved spermatogenesis and a decrease in testicular side effects. The addition of VE to the treatment of hyperthyroid rats with CBZ reduced testicular side effects and seminiferous tubular affection when potentially improving spermatogenesis. Further research is needed to elucidate the underlying mechanisms fully.

Histological Study of Alteration in Testes and Epididymis of Domestic Rabbits Caused by Tribulus Terrestris and Vitamin E.

Tribulus Terrestris (TT) is a common herbal plant with different categories that grows in many countries of the world. Traditional Chinese and Indian therapies have used TT for infertility treatment and also as a powerful antioxidant agent. Therefore, this study aimed to use this plant supplemented with vitamin E to study their combined effects on the histological condition of the testicle and epididymis of rabbits. This study was performed on 28 healthy male rabbits (445-950 g, 2.0-3.0 months old) that were randomly divided into four groups (n=7). All animals were subjected to clinical examination to ensure that they were free of external and internal parasites with the use of some preventive treatments. The animals were housed individually (cage size: 50 cm×50 cm×40 cm) over the 60-day study period starting from January 2022, with an adaptation period of two weeks. Tribulus Terrestris and vitamin E treatments were as follows: the first group (G1) was daily fed on a standard diet and kept as the control group, the second group (G2) was daily fed on the same ration plus 1 g of TT (animal/daily), the third group (G3) was daily fed on the same ration plus 1 g of TT supplemented with 60 mg of vitamin E (orally) (animal /daily), and the fourth group (G4) was daily fed on the same ration, with the addition of 60 mg vitamin E per animal (orally). The morphometric investigation, macroscopic variables (including body weight, testicular weight, and volume), and the microscopic parameters of the testicular seminal tubule were measured. The histological section showed the absence of negative effects after the oral administration of TT at a dose of 1 g per day and 60 IU vitamin E for each animal. However, there was a positive effect on spermatogonia and spermatocytes in all animals, while the spermatogonia in the experimental groups were more dense, especially in the second and third groups, compared to the control group. The seminiferous tubules were significantly lined with spermatogonia, spermatocytes, and round spermatids (P<0.5) in the experimental groups, compared to the control group. Nevertheless, the epididymis tissue did not show traces of histological changes, such as epididymal hyperplasia. Sperms were more frequent in the lumens of the epididymis as well as the lumens larger than those of the control. Based on the results of this study, it can be concluded that the pole plant and vitamin E have a positive effect on the epithelial lining of the seminiferous tubules and the epididymis with an increase in sperm formation and differentiation towards maturity.

Antioxidant action of alpha lipoic acid on the testis and epididymis of diabetic rats: morphological, sperm and immunohistochemical evaluation

ABSTRACT Introduction Chronic hyperglycemia is caused by diabetes mellitus-committed genital morphophysiology, and oxidative stress is one of the main factors involved in this process. Alpha lipoic acid (ALA) can prevent metabolic and morphological changes in diabetic individuals. Objectives In present study, we evaluated the effects of regular ALA consumption on the spermatogenesis and histoarchitecture in the male genital system of diabetic rats. Materials and Methods Thirty-two Wistar rats were divided into groups: Control (CG); Diabetic Control (DCG), receiving commercial diet: ALA Group (ALAG) and Diabetic ALA Group (DALAG), fed diets with added ALA (300 mg/Kg bw). The diabetic groups received a single injection of streptozotocin (60 mg/kg). After sixty days of the diet, the animals were euthanized, and semen, testis and epididymis samples were collected. A histomorphometric analysis was performed to determine the epithelial height, tubular and luminal diameter, tubular and luminal area of seminiferous tubules and each epididymal region. Sertoli cells were evidenced using the antivimenti antibody and were quantified. The results were statistically analyzed by the ANOVA test. Results At the end of the experiment, the DALAG glycemia was significantly lower than DCG. The histomorphometric parameters of the seminiferous and epididymal tubules did not show improvement in the DALAG. However, there was an improvement in the DALAG in terms of the concentration, motility and percentage of spermatic pathologies, as well as in the number of Sertoli cells (p<0.001). Conclusions The results demonstrated that supplementation with the ALA antioxidant retards testicular lesions and preserve the process of spermatogenesis in diabetes.

Protective effect of Lepidium sativum seed extract on histopathology and morphology of epididymis in diabetic rat model / Efecto protector de extracto de semilla Lepidium sativum sobre la histopatología y morfología del epidídimo en modelo de rata diabética

Diabetes mellitus is a frequent and serious metabolic illness all over the world and plants have been a desirable source of medicine recently. Diabetes has unpleasant effect on male reproductive system and it may lead to male infertility. It causes erectile dysfunction and reduces ejaculate volume by affecting the health of small blood vessels and the small nerves that control ejaculation and also decreases libido by decreasing testosterone levels. Current study evaluated the possible protective efficiency of Lepidium sativum (Garden cress) seed extract on fasting blood sugar (FBS) and then assessed histopathological change of epididymis in streptozotocine (STZ)-induced diabetic rats. We randomly categorized 50 adult male Wistar rats into five groups (each 10 rats). Group 1 was control placebo group receiving only 0.1 ml normal saline via gastric gavages, Group 2 as control diabetic rats received an intraperitoneal (IP) injection of STZ 60 mg/kg body weight. Rats with FBS >250 mg/dl were considered as diabetic. Group 3 were diabetic rats receiving insulin in dose 3U/100 g body weight and Groups 4 and 5 were diabetic rats that received 0.1 cc of 200 and 400 mg/kg, ethanol extract of Lepidium sativum seed by gavages daily. One day after the last gavages, rats were anesthetized by chloroform. Epididymis duct was removed from abdomen and weighed with a digital scale. Afterwards, samples were putted in Bouin's solution for histological measurement. Administration of 200 and 400 mg/ml doses of Lepidium sativum seed extract increased epithelium height and decreased interstitial volume density and fibro muscular thickness significantly. Also, volume density of epithelium, fibro muscular, lumen and interstitial decreased significantly. Tubular and lumen diameter did not change significantly in different groups. It appears Lepidium sativum seed extract is a beneficial protective supplementary agent against adverse effects of diabetes on male reproductive system.

La diabetes mellitus es una enfermedad metabólica frecuente y grave que afecta a los hombres en todo el mundo. Recientemente, las plantas han sido una fuente deseable de medicina para este tipo de enfermedad. La diabetes tiene un efecto perjudicial en el sistema reproductivo masculino y puede conducir a la infertilidad. Causa disfunción eréctil y reduce el volumen de la eyaculación al afectar los pequeños vasos sanguíneos y los nervios que controlan la eyaculación. También disminuye la libido reduciendo los niveles de testosterona. El presente estudio evaluó la posible eficacia protectora del extracto de semilla de Lepidium sativum en la glucemia en ayunas y también se evaluó el cambio histopatológico del epidídimo en ratas diabéticas inducidas por estreptozotocina (STZ). Se dividieron aleatoriamente 50 ratas Wistar macho adultas en cinco grupos de 10 ratas cada uno. El grupo 1 recibió 0,1 ml de solución salina normal a través de los gavajes gástricos, el grupo 2 de ratas diabéticas control recibió una inyección intraperitoneal (IP) de STZ 60 mg / kg de peso corporal. Las ratas con FBS> 250 mg / dl se consideraron como diabéticas. El Grupo 3 eran ratas diabéticas que recibieron insulina en dosis de 3 U/ 100 g de peso corporal y los Grupos 4 y 5 estaban compuestos por ratas diabéticas que recibieron 0,1 cc con 200 y 400 mg / kg, de extracto de etanol de semillas de Lepidium sativum por gavajes diarios. Un día después de los últimos gavages, las ratas fueron anestesiadas con cloroformo. Se extrajo el epidídimo y se pesó con una pesa digital. Posteriormente, las muestras se pusieron en solución de Bouin para el estudio histológico. La administración de dosis de 200 y 400 mg / ml de extracto de semilla Lepidium sativum aumentó la altura del epitelio y disminuyó significativamente la densidad volumétrica intersticial y el grosor fibromuscular. Además, la densidad volumétrica del epitelio fibromuscular, lumen e intersticio disminuyeron significativamente. El diámetro tubular y el lumen no cambiaron significativamente en los diferentes grupos. El extracto de semilla de Lepidium sativum es un agente complementario beneficioso protector contra los efectos adversos de la diabetes en el sistema reproductor masculino.

Intestinal mucinous adenocarcinoma with metastases to epididymis, testis and tunica albuginea in a dog

A case of intestinal mucinous adenocarcinoma with metastasis to gonadal tissue is reported. A 13-year-old, male, poodle dog presented with intestinal and peritoneal masses, as well as infiltrative masses in testicular tunics. Samples were biopsied and submitted for histopathological analysis. Microscopically, intestinal lesion consisted of an adenocarcinoma (mucinous type), with infiltration of muscular layers and mesenteric adipose tissue. In gonadal tissue, there was neoplastic infiltration of epididymis and tunica albuginea (with a predominantly tubular pattern), and testicular parenchyma (with a predominantly signet-ring cell pattern). Immunohistochemistry was positive for CDX2 and pancytokeratin, and negative for vimentin, supporting the diagnosis of intestinal mucinous adenocarcinoma with metastases to epididymis, testis and tunica albuginea.

Phyllanthus emblica l. branch extract ameliorates testicular damage in valproic acid-induced rats / El extracto de la rama de Phyllanthus emblica l. disminuye el daño testicular inducido por ácido valproico en ratas

Valproic acid (VPA), widely used in treating epileptic patients, can damage reproductive parameters causing male infertility. This study aimed to investigate protective effect of Phyllanthus emblica L. branch (PE) extract on rat testicular damage induced with VPA. Male rats were divided into 6 groups (control, VPA, 250 mg/kgBW PE only, and 50, 100, 250 mg/kgBW PE+VPA, respectively). Animals were pretreated with PE for 23 days and co-administered with VPA for 10 days before all reproductive parameters were determined. The results showed all doses of PE significantly protected the decrease testicular weight and testosterone level in VPA rats. PE significantly improved the decrease sperm concentration in VPA treated rats. Moreover, testicular histology of PE+VPA groups showed declining of testicular histopathologies as compared to VPA group. Therefore, it seems that PE branch extract can prevent testicular damages including male reproductive parameters in rats induced with VPA.

El ácido valproico (AVP) es utilizado frecuentemente en el tratamiento de pacientes epilépticos y puede dañar los parámetros reproductivos que causan la infertilidad masculina. Este estudio tuvo como objetivo investigar el efecto protector de la rama Phyllanthus emblica L. (PE) sobre el daño testicular de ratas inducidas con AVP. Ratas machos fueron divididas en 6 grupos (control, AVP, PE 250 mg/kg peso corporal, APV+ PE 50, 100, 250 mg/kg peso corporal, respectivamente). Los animales fueron pretratados con PE durante 23 días y se administró AVP durante 10 días antes de medir todos los parámetros reproductivos. Los resultados mostraron que todas las dosis de PE protegen significativamente el peso y los niveles reducidos de testosterona testicular en ratas con AVP. El extracto de PE mejoró significativamente la concentración de espermatozoides en ratas tratadas con AVP. Por otra parte, la histología testicular de los grupos PE+AVP mostró disminución de la histopatología testicular en comparación con el grupo tratado sólo con AVP. Por lo tanto, parece que el extracto de la rama PE puede prevenir daños testiculares incluyendo los parámetros reproductores masculinos en ratas inducidas con AVP.

The effects of maternal low protein and estrogen on sexual behavior and testicular maturation in male rats / Efectos de niveles maternos bajos de estrógeno y proteína sobre el comportamiento sexual y maduración testicular en ratas macho

In recent years, disorders related to the development and function of the male reproductive tract has increased, thus generating a surprising decrease in semen volume and sperm count. We examined the effects of low protein and estrogen on sexual behavior and testicular maturation in male rats. We also examined FSH, LH and testosterone levels and histological damage of testis tissue. The male rats were subjected to standard long-term treatment with estradiol by oral and paranteral delivery. The number of mounts, copulatory efficiency and ejaculation latencies for the paranteral protein diet (PPD) group was significantly lower than those in a group nourished with a low protein diet (LPD) and oral protein diet (OPD) groups (P<0.05). Testes and epididymis sections were examined by four grades, according to the level of damage of epithelium in the testes and epididymis. Higher histological damage was also detected in the PPD group. In conclusion, the present study confirmed that unwanted estrogen effects were higher in the paranteral administered group on examination of sexual behavior and histological damage of epithelium in the testes and epididymis of male rats.

En los últimos años, los trastornos relacionados con el desarrollo y la función del tracto reproductivo masculino han aumentado, lo que genera una disminución importante en el volumen de semen y el conteo de espermatozoides. Se examinaron los efectos de niveles bajos en proteínas y estrógeno en el comportamiento sexual y la maduración testicular en ratas macho. También se examinaron FSH, LH y los niveles de testosterona y el daño histológico de tejido testicular. Las ratas macho fueron sometidas al tratamiento y administración estándar a largo plazo con estradiol por vias oral y parenteral. El número de montajes, eficiencia de copulación y latencias de eyaculación para el grupo de dieta de proteínas parenteral (DPP) fue significativamente menor que los del grupo con una dieta baja en proteínas (PBD) y de proteína oral baja (POB) grupos (P<0,05). Fueron examinados los testículos y epidídimo de acuerdo a cuatro grados, en relación al nivel de daño del epitelio en los testículos y epidídimo. También se detectó un mayor daño histológico en el grupo DPP. En conclusión, se confirma que los efectos no deseados del estrógeno fueron mayores en el grupo con administración parenteral en el examen de conducta sexual y en el daño histológico del epitelio en los testículos y el epidídimo de ratas macho.

Effects of traction on the spermatic cord of rats

PURPOSE: To determine whether tension in the spermatic cord of rats causes lesions in the testis, epididymis or vas deferens. METHODS: Forty Wistar rats were randomly allocated into four groups. A traction force of 1.6 Newton (N) in group I and 1 N in group II was applied to the right spermatic cord. Group III was the sham, and group IV served as the control. RESULTS: Testicular lesions occurred on the right side in 66.7% of the rats and on the left side in 46.1% of the rats. The testes showed a decreased number of Sertoli cells, necrosis and a decreased number of germ cells in the seminiferous tubules. Anatomopathological changes in the vas deferens were not identified. There was no decrease in the thickness of the muscle wall of the vas deferens. In the right epididymis, 71.8% of the animals showed a reduction and 5% showed an absence of intraluminal sperm. In the left epididymis, 37.5% of the rats showed a reduction. The volume and the final testicular weight of the right side in group IV was different from those in the other groups. CONCLUSIONS: Anatomopathological lesions were found in the testis and epididymis. .
