RESUMO

Context Carbon tetrachloride (CCl4 ) is a chemical that is still widely used in industry and has been shown to cause structural defects in rat testicles through oxidative stress. Aims In our study, the effect of curcumin on CCl4 -mediated testicular damage was investigated. Methods Twenty-four adult Wistar albino male rats weighing 300-350g were divided into four groups: control group (olive oil was applied by gavage every consecutive day for 3weeks); curcumin and CCl4 +curcumin groups (200mg/kg curcumin dissolved in olive oil was given by gavage once a day, every consecutive day for 3weeks); and CCl4 and CCl4 +curcumin groups (0.5mL/kg CCl4 was dissolved in olive oil at a ratio of 1/1 and given by i.p. injection every other day for 3weeks). Tissue samples were examined histopathologically, histomorphometrically, immunohistochemically and biochemically. Key results CCl4 disrupted both testicular morphology and testosterone synthesis, whereas curcumin treatment resulted in an improvement in testicular morphology and biochemical parameters, as well as a decrease in caspase-3 and tumour necrosis factor-α expression. Conclusions Curcumin has a protective effect on testicular tissue damage caused by CCl4 with its anti-inflammatory, antiapoptotic and antioxantioxidant properties. Implications Curcumin can prevent testicular damage due to CCl4 , an environmental pollutant.

RESUMO

Approximately 90% of diabetic males have varying degrees of testicular dysfunction. The current study investigates the possible beneficial consequences of ranolazine against T1DM-induced testicular dysfunction in rats. Thirty-two male Sprague Dawley rats were assorted into 4 groups; normal, diabetic (single 50 mg/kg STZ, I.P.) and ranolazine (40 and 80 mg/kg, orally). The present investigation revealed that the hypoglycemic impact of ranolazine significantly improved the testicular weight and body weight of the final rats, as well as the concentration of blood testosterone, sperm count, and viability, all of which were associated with STZ-induced testicular dysfunction. Furthermore, as demonstrated by elevated reduced glutathione (GSH) activity and lowered malondialdehyde (MDA) levels, diabetic rats administered ranolazine showed a noteworthy improvement in the oxidant/antioxidant ratio. Furthermore, a substantial rise in beclin-1 concentration was seen in conjunction with a significant decrease in thioredoxin-interacting protein (TXNIP) and interleukin-18 (IL-18) concentrations when ranolazine was administered. Although ranolazine exhibited a reduction in inflammation as seen by lower expression of nuclear factor-κB (NF-κB) and cluster of differentiation (CD68) in the testicles, these biochemical findings were validated by improvements in the morphological and histopathological outcomes of both the pancreatic and testicular tissues. In conclusion, daily oral administration of ranolazine (40 and 80 mg/kg) for 8 weeks could be a promising therapy for T1DM-induced testicular dysfunction through its dose-dependent anti-oxidant and anti-inflammatory effects.

RESUMO

An 8 yr old male German shorthaired pointer was presented on July 4, 2022, for acute abdominal and testicular pain. The dog was vasectomized at an unknown age under the care of his previous owners. The dog had an enlarged, painful left testis, scrotal edema, and an enlarged, nonpainful prostate. Abdominal ultrasound revealed mild peritoneal and retroperitoneal effusion, orchiepididymitis, enlarged ductus deferentes and testicles, and suspected benign prostatic hyperplasia versus prostatitis. Peritoneal effusion cytology revealed seminoperitoneum with marked neutrophilic inflammation. Peritoneal effusion aerobic culture and Brucella canis rapid slide agglutination test were negative. The dog was hospitalized overnight with IV antibiotic therapy and analgesics. The following day, the dog's abdominal pain, testicular pain, and scrotal edema were resolved. The dog was discharged and castrated after completion of antibiotic therapy and complete resolution of clinical signs. Testicular histopathology results were not available. Seminoperitoneum is uncommon in dogs and is a rare diagnosis for dogs with acute abdominal pain. This is the second known reported case of a seminoperitoneum in a vasectomized dog.

RESUMO

BACKGROUND: Genitourinary tuberculosis (GUTB) is a common form of extrapulmonary TB (EPTB) in children. An example of GUTB is epididymal TB, which usually presents unspecific chronic clinical manifestations. Definitive diagnosis can be conducted based on bacteriologic confirmation and histopathologic results, but this is challenging due to the paucibacillary nature of EPTB. Therefore, we reported the challenges in diagnosing isolated epididymal TB in an adolescent male. CASE PRESENTATION: A 16-year-old male presented to respirology clinic with painful swelling of the left scrotum for 3 months before visiting to the hospital. The symptoms were associated with persistent coughing for 2 months, and physical examination of the left scrotum showed swelling accompanied by cardinal signs. A palpable hard mass was found on the left scrotum, with firm borders, measuring 7 × 4 cm. Laboratory examination and tumor markers were within normal limits, although leukocyturia was found, and the urine culture was negative. Genital ultrasound (US) showed epididymitis sinistra with septal hydrocele, while magnetic resonance imaging (MRI) indicated inhomogeneous left epididymitis with bilateral inguinal lymph node enlargement. Although TB evaluation presented a negative purified protein derivative (PPD) test and bacteriologic examination, chest X-ray (CXR) showed perihilar lymphadenopathy. Based on the clinical and radiologic results suggesting TB, the patient was diagnosed with isolated epididymal TB and received quadruple antituberculosis therapy (ATT) for 6 months. After treatment, the left testicle size started to shrink and was equal to the right testicle, also, there were no signs of inflammation, the body weight increased by 5 kg, and cough disappeared. Sperm analysis at the end of treatment indicated teratozoospermia, which was subsequently treated by the urologic surgery department. CONCLUSIONS: Biopsy and bacteriologic confirmation for TB epididymitis were challenging to perform in the clinical setting. Epididymal TB should be considered in adolescent males with complaints of chronic scrotal swelling and pain. Clinical judgment based on history taking, physical examination, and radiologic features supporting TB features could be helpful in accurate and fast diagnosis for favorable outcome.

RESUMO

This study was done to estimate the testicular histological alterations induced by Busulfan (BUS) and compare the possible protective effects of melatonin (MT) and platelet rich plasma (PRP) in a rat model. Sixty-four male rats were dispersed into: control group, BUS group, melatonin group, and PRP group. Blood samples were processed for biochemical analysis. Tissue specimens were managed for light and electron microscopic studies. Immunohistochemical expression of vimentin and proliferating cell nuclear antigen (PCNA) was performed. Busulfan induced severe testicular damage in all studied methodologies. It showed a statistically significant decrease in serum testosterone and elevation of MDA when compared to the control group. Abnormal testicular cytostructures suggesting defective spermatogenesis were observed: distorted seminiferous tubules, deformed spermatogenic cells, low germinal epithelium height, few mature spermatozoa, and also deformed barrier. Vimentin and PCNA expressions were reduced. Ultrastructurally, Sertoli cells and the blood testis barrier were deformed, spermatogenic cells were affected, and mature spermatozoa were few and showed abnormal structure. Both melatonin and PRP induced improvement in all the previous parameters and restoration of spermatogenesis as confirmed by improvement of Johnsen's score from 2.6 ± .74 to 7.6 ± .92. In conclusion, melatonin and PRP have equal potential to ameliorate the testicular toxicity of BUS. Melatonin can provide a better noninvasive way to combat BUS induced testicular injury.

RESUMO

Polyorchidism, a congenital malformation characterized by supernumerary testes (SNTs), is usually revealed incidentally during ultrasound or open scrotal surgery. In the approximately 200 cases so far published in the literature, the left side is affected more often than the right. Despite the rarity of this anomaly, a surgeon must have basic knowledge of its embryological basis and classifications to implement proper treatment and avoid overlooking it, since the consequences could harm the patient. This review summarizes previous classifications. It can be assumed that determining the risk of malignancy, and the level of reproductive potential based on location, vascularization, ductus deferens drainage, and environmental factors (e.g., temperature) affecting the SNTs, indicates the best approach to management. Therefore, we have created a new classification based on previous ones, addressing the aforementioned issues, which will guide the clinician to select the most appropriate treatment.

RESUMO

Methadone (Met) is the most common treatment for opioid addiction. Although Met is effective for treatment of opioid dependence, sexual dysfunctions and infertility have been reported as a major problem in patients under Met treatment. The present study aimed to evaluate the effect of melatonin and N-acetylcysteine (N) on morphine and Met-induced oxidative stress, apoptosis, suppression of blood sexual hormones, impairment in sperm parameters, and sexual dysfunction. Adult male Wistar rats (n = 66) were randomly divided into 11 equal groups (n = 6) as follows: control, sham, morphine, Met, Met+N, Met+ melatonin, Met+melatonin+N, morphine+ Met, morphine+Met+ melatonin, morphine+Met+N, and morphine+Met+ melatonin+N groups. On day 56 post-treatment, the blood was collected from the tail and the serum levels of sex hormones were evaluated, then the rats were sacrificed, and their bilateral testes and epididymis were retrieved for histological, immunohistochemical, molecular, testicular tissue stress oxidative status, and sperm parameters assays. Exposure to morphine, Met, and shift of morphine to Met resulted in testicular degeneration that can be attributed to generating the stress oxidative-induced- apoptotic testicular cell death and impairing spermatogenesis. Melatonin and N alone and particularly, in combination with each other improved testicular degeneration, sex hormone suppression, and testicular function mediated by increasing the testicular antioxidant capacity and inhibition of the apoptosis pathway. It's suggested that oral administration of antioxidants may be an effective treatment for attenuating some opioid-related testicular dysfunction and degeneration.

RESUMO

BACKGROUND: Spontaneous idiopathic testicular hemorrhage is an extremely rare entity with few published reports in the literature. CASE PRESENTATION: We report a case of a 15-year-old boy who had been experiencing intense, left scrotal pain for the previous twelve hours. No previous history of trauma or bleeding disorders. The left testis was enlarged and tender. Left orchiectomy was performed. The entire testis was dusty and dark grossly. Microscopic sections show diffuse intratesticular bleeding with intact seminiferous tubules and spermatogenesis. CONCLUSIONS: Spontaneous idiopathic testicular hemorrhage should be considered when evaluating patients with acute scrotal pain. Clinical and ultrasonographic findings and histopathologic evaluation are mandatory to diagnose it.

RESUMO

OBJECTIVE: Klinefelter syndrome is the most common chromosomal disorder in males and the most common cause of hypergonadotropic hypogonadism. We describe the natural history of testicular dysfunction in patients with Klinefelter syndrome through the integration of clinical, hormonal, and quantitative ultrasound data in a life-course perspective. DESIGN: Prospective semilongitudinal study. METHODS: We included 155 subjects with 47,XXY karyotype (age range: 7 months-55 years) naïve to testosterone replacement therapy. Subjects were divided according to pubertal stage and age group (transition age and adults). Serial clinical, hormonal, and testicular ultrasound (US) assessments were performed. RESULTS: Testicular development progresses until Tanner stage 4, with subsequent regression, whereas Sertoli and germ cell impairment is not hormonally detected before Tanner stages 3-4, as reflected by normal inhibin B values until stage 4 and the fall in the inhibin B/follicle-stimulating hormone ratio thereafter. The testosterone/luteinizing hormone ratio peaks during Tanner stages 2-3 and declines from Tanner stage 4 onward, preceding the development of overt hypogonadism. US echotexture progressively worsens until transition age, reflecting ongoing gonadal compromise, whereas quantitative US echotexture measures and the presence of both hypoechoic lesions and microlithiasis independently and significantly predict a lower circulating testosterone level. CONCLUSIONS: The findings from this large prospective study contribute to our understanding of the natural history of testicular dysfunction in Klinefelter syndrome, underlining the importance of quantitative testicular US in infancy and childhood, as well as during pubertal development and transition age, for the optimal care of Klinefelter syndrome patients.

RESUMO

Oxido-inflammatory stress has been involved in lead-induced testicular dysfunction and plants rich in anti-oxidants has been reported to be beneficial in combating heavy metal poisonings in animal studies. However, cabbage juice protective effect on lead-induced testicular dysfunction was investigated in this study. Twenty male Wistar rats were selected into four (n = 5) groups and given distilled water (1 ml/100 g body weight), lead acetate (25 mg/kg body weight), cabbage juice (1 ml/100 g body weight), and lead acetate with cabbage juice, respectively. All treatments were administered orally for 28 days. Sperm count, motility, viability, testosterone, luteinising hormone and follicle-stimulating hormone, testicular Bcl-2 expression, and enzymatic anti-oxidant capabilities were considerably (p < 0.05) decrease in lead-treated animals. However, cabbage juice significantly (p < 0.05) elevated these parameters. Testicular malondialdehyde, tumour necrosis factor-α, nitric oxide and interleukin-6 was elevated by lead acetate. When comparing cabbage juice-treated animals to lead-treated animals, all of these parameters were considerably (p < 0.05) downregulated in cabbage juice-treated animals. Following lead administration, the testes' histomorphological alterations were not totally recovered despite therapy with cabbage juice. Conclusively, this study suggest that cabbage juice mitigates testicular dysfunction associated with lead exposure via its anti-oxidant, anti-inflammatory, anti-apoptotic and androgenic properties.

RESUMO

Polyorchidism is a congenital malformation of the urogenital system that is usually found incidentally in adolescent age groups. Ultrasound and MRI are effective non-invasive diagnostic modalities which can differentiate this condition from other intrascrotal pathologies. Ultrasonography is mostly used in initial steps of diagnostic approach; however, MRI is considered as a modality to confirm diagnosis and evaluate possible malignancy. We report an extremely rare case of pentaorchidism (five testicles), presented with a left hemiscrotum mass. Diagnosis was made based on physical examination, laboratory analysis (testicular germ cell tumour markers and semen analysis) and imaging. Finally, close surveillance with ultrasound and physical examination was recommended for follow-up of this uncomplicated patient.

RESUMO

We present an unusual case of sudden onset of pain in the left testis in a patient with a previous medical history of right orchiectomy due to hemorrhagic infarction. A partial orchiectomy was performed with complete removal of the lesion and reconstruction of the testicular parenchyma. Histopathological assessment confirmed segmental testicular infarction without the presence of malignancy. The patient subsequently received anticoagulant therapy.

RESUMO

BACKGROUND: Cancer and its therapies can impact fertility in various ways, and therefore a growing number of cancer survivors face fertility as a significant concern. The cytotoxic alkylating agent cyclophosphamide (CP) is commonly used as an antineoplastic agent; unfortunately, its use is significantly associated with male infertility and damage to the reproductive system. AIM: The present study aimed to assess the possible beneficial effects of Irbesartan (IRB) in a rat model of CP-induced testicular toxicity. MAIN METHODS: The effects of treatment were assessed by measuring peroxisome proliferator-activated receptor gamma (PPAR-γ) expression via qRT-PCR, the immunohistochemical (IHC) assessment of apoptotic markers, NOD-like receptor protein 3 (NLRP3), and nuclear factor-κB (NF-κB), determination of the count and viability of epididymal sperm, oxidative stress markers via biochemical analysis, serum testosterone, caspase-1, and interleukin-18 (IL-18) levels via ELISA, histopathological assessment, and fibrosis by Masson's trichrome (MT) stain. KEY FINDINGS: There was a significant increase in malondialdehyde (MDA), caspase-1, and IL-18 contents, NF-κB, NLRP3, Bcl-2-associated X protein (Bax), caspase-3, and MT staining in testicular tissue after CP administration compared to the normal control group. Whereas reduced glutathione (GSH), superoxide dismutase (SOD), PPAR-γ expression, B-cell lymphoma-2 (Bcl-2) staining, serum testosterone, and the count and viability of epididymal sperm were decreased compared to the normal control group. The IRB treatment has reversed CP-induced testicular toxicity. SIGNIFICANCE: It is possible to conclude that IRB revealed a significant testicular protective effect against CP via antioxidant, anti-apoptotic, and anti-inflammatory effects.

RESUMO

We have encountered a lesion of the pediatric testis, termed "nodular maturation," that clinically mimics a testicular neoplasm causing ultrasound abnormalities that may lead to surgical excision. To our knowledge, it has only been described anecdotally in textbooks without a series or description in the literature. We, therefore, report 8 cases in pediatric patients emphasizing the clinical presentation, ultrasound findings, histologic features, and clinical follow-up information. Patients ranged in age from 5 to 11 years (mean: 7.9 y). Precocious puberty was identified in 1 patient as isolated penile enlargement without other signs; another had a history of McCune-Albright syndrome, but did not have signs of precocious puberty; others had no clinical manifestations. All patients had testicular abnormalities on ultrasound; 6 had a discrete lesion and 2 showed diffuse testicular enlargement. In the 6 cases with available data, mean size of the lesion on ultrasound was 0.9 cm (range: 0.4 to 1.7 cm). In the 3 cases for which macroscopic descriptions were available, no gross abnormalities were noted in the testicular parenchyma, despite the ultrasound findings. Histologically, nodular maturation occurred as a zone of more mature testicular parenchyma having larger, lumen-bearing seminiferous tubules that contrasted with the smaller, immature cords of the remaining parenchyma. The mature tubules showed germ cell maturation (to the level of late spermatids/spermatozoa in 6 cases), mature Sertoli cells, and, in 4 cases, admixed nodules of mature Leydig cells. Of the 6 patients with available follow-up information, none developed a testicular neoplasm. Given its ability to cause a lesion on ultrasound leading to surgical intervention, pathologists, radiologists, and urologists should be aware of nodular maturation.

RESUMO

Clinical utilization of doxorubicin (DOX), which is a commonly used chemotherapeutic, is restricted due to toxic effects on various tissues. Using hesperetin (HST), an antioxidant used in Chinese traditional medicine protects testis against DOX-induced toxicity although the molecular mechanisms are not well-known. The study was aimed to examine the possible role of the mechanistic target of rapamycin kinase (mTOR) and dynamin 1-like dynamin-related protein 1 (DRP1) in the therapeutic effects of HST on the DOX-induced testicular toxicity. Rats were divided into Control, DOX, DOX + HST, and HST groups (n = 7). Single-dose DOX (15 mg/kg) was administered intraperitoneally and HST (50 mg/kg) was administered by oral gavage every other day for 28 days. Total antioxidant status (TAS), histopathological evaluations, immunohistochemistry, and gene expression level detection analyses were performed. Histopathologically, DOX-induced testicular damage was ameliorated by HST treatment. DOX reduced testicular TAS levels and increased oxidative stress markers, 8-Hydroxy-deoxyguanosine (8-OHdG), and 4-Hydroxynonenal (4-HNE). Also, upregulated mTOR and DRP1 expressions with DOX exposure were decreased after HST treatment in the testis (p < 0.05). On the other hand, DOX-administration downregulated miR-150-5p and miR-181b-2-3p miRNAs, targeting mTOR and mRNA levels of beclin 1 (BECN1) and autophagy-related 5 (ATG5), autophagic markers. Furthermore, these levels were nearly similar to control testis samples in the DOX + HST group (p < 0.05). The study demonstrated that HST may have a therapeutic effect on DOX-induced testicular toxicity by removing reactive oxygen species (ROS) and by modulating the mTOR and DRP1 expressions, which have a critical role in regulating the balance of generation/elimination of ROS.

RESUMO

The two gonadal steroid hormones, testosterone and estrogen, regulate spermatogenesis by proliferation, differentiation, and apoptosis of testicular cells. It has been reported that heat stress or increased scrotal temperature impairs spermatogenesis in many mammals. Moreover, testicular heat stress has also been shown to suppress testosterone and estrogen biosynthesis. Furthermore, it is well known that testosterone and estrogen are important for testicular activity. Therefore, we hypothesised that exogenous testosterone and estrogen, alone or in combination, might alleviate the testicular activity in a heat-stressed rat model. To the best of our knowledge, this will be the first report of the exogenous treatment of both testosterone and estrogen in the heat-stressed rat. Our results showed that a combined testosterone and estrogen treatment significantly increased sperm concentration. The histopathological analysis also exhibited a normal histoarchitecture in the combined treatment group along with decreased oxidative stress. The improved spermatogenesis in the combined treatment group was also supported by the increase in PCNA, GCNA, tubule diameter, germinal epithelium height, and Johnsen score in the combined treatment group. Furthermore, the combined treatment also increased the expression of Bcl2, pStat3, and active caspase-3 and decreased expression of Bax. Thus, increased proliferation, apoptotic and anti-apoptotic markers, along with improved histology in the combined treatment group suggest that estrogen and testosterone synergistically act to stimulate spermatogenesis by increasing proliferation and differentiation of germ cells and may also remove the heat-induced damaged germ cells by apoptosis. Overall, the final mechanism of testosterone- and estrogen-mediated improvement of testicular activity could be attributed to amelioration of oxidative stress.

RESUMO

Until molecular diagnostics become available, individualized risk assessment for men with testicular microlithiasis, counseling on the current evidence base regarding the benefit of testicular biopsy or testicular self-examination, and a patient-centered approach provide the framework for the best quality of care for the individual patient.

RESUMO

The cancer therapy using cyclophosphamide (CP) has been associated with adverse effects on the testicular function that raises concerns about the future fertility potential among cancer survivors. Curcumin, a polyphenol, has shown to possess a plethora of biological functions including tissue protective effects. In the present study, we investigated the protective effects of curcumin nanocrystals (NC) in mitigation of CP-induced testicular toxicity. Healthy adult (8-10 week) and prepubertal (2 week) male Swiss albino mice were injected with a single dose of CP (200 mg/kg) intraperitoneally (i.p). NC (4 mg/kg, i.p.) was administered every alternate day, for 35 days in adult mice while, a single dose of NC was injected intraperitoneally to prepubertal mice 1 h prior to CP. Administration of multiple doses of NC ameliorated CP-induced testicular toxicity in adult mice, which was evident from the improved sperm functional competence, sperm chromatin condensation, seminiferous tubule architecture and decreased apoptosis in testicular cells. Further, administration of NC 1 h prior to CP in prepubertal mice modulated the expression of genes pertaining to proliferation, pluripotency, DNA damage and DNA repair in spermatogonial cells at 24 h after the treatment. Overall, these results suggest that NC could be a promising chemoprotective agent, which can have potential application in male fertility preservation.
