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

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

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

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

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

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

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.

RESUMO

Methotrexate (MTX) is commonly used as a therapeutic agent in the treatment of malignancies and autoimmune disorders. Risk of subsequent infertility following MTX administration has been reported as a significant side effect due to testicular toxicity. The aim of the study was to evaluate the modulatory effects of Ginkgo biloba (standardized extract, EGb 761) on MTX-induced testicular oxidative stress, energy deficits and spermatogenic status in rats. All groups received intraperitoneal injection of MTX (0.5 mg/kg) twice weekly for four weeks except the control group that received the corresponding vehicles. Other groups received oral EGb761, at doses 25, 50 or 100 mg/kg/day, for four weeks, concurrently with MTX. Blood and semen sampling followed by testis dissection were performed 24 h after last EGb 761 treatment. Semen was examined for sperm progressive motility, percent of normal spermatozoa and sperm cell concentration as well as seminal plasma essential and non-essential amino acids. Serum LH, FSH and testosterone were detected as well as testicular MDA, GSH, GSSG, TNF-α, IL-1ß, IL-6, NF-κB and the nuclear, cytoplasmic and mRNA expression levels of Nrf-2 besides the testicular cell energy; AMP, ADP and ATP. Histopathological studies of interstitial fibrosis and the severity of germ cell degeneration were also conducted. MTX induced significant decline in sperm quality along with decreased essential and non-essential amino acids in seminal plasma. MTX reduced serum FSH, LH and testosterone as well as testicular ATP, GSH and Nrf2, while increased levels of testicular ADP, AMP, MDA, GSSG and TNF-α. Results were confirmed by prominent interstitial fibrosis and severe germ cell degeneration in MTX group. Concurrent treatment with EGb 761 alleviated MTX-induced testicular insult evidenced by amelioration of oxidative stress biomarkers, energy functions, seminal sperms abnormalities and spermatogenesis status. The present study suggests a beneficial role of EGb 761 in MTX-induced testicular injury and subsequent distortion of spermatogenesis.

RESUMO

Although circular RNAs (circRNAs) can function as microRNAs (miRNAs) sponges to participate in spermatogenesis, little is known about the functions of circRNAs in testis exposed to formaldehyde. In this study, twenty-four male SD rats (6-8 weeks) were randomly assigned to four groups, including a control group, 0.5, 2.46, and 5 mg/m3 formaldehyde exposure groups, inhaling formaldehyde for eight consecutive weeks. The RT-qPCR was used to detect the expression of rno_circRNA_016194; the testicular injuries were observed by testicular histopathology. Our study illustrated up-regulated rno_circRNA_016194 was dose-dependent with formaldehyde. Simultaneously, the testicular histopathology showed an obvious damages in the 2.46 and 5 mg/m3 formaldehyde exposure rats. Combined with bioinformatics analysis, the rno-miR-449a-5p was predicted and verified that its expression decreased in the testis exposed to formaldehyde. Meanwhile, the testicular morphometry changes were contrary to the expression of rno_circRNA_016194 and consistent with rno-miR-449a-5p. Moreover, bioinformatics analysis also prompted the potential downstream target gene for rno_circRNA_016194/rno-miR-449a-5p was Atg4b, and Atg4b expression was up-regulated in rats exposed to formaldehyde verifying by Western blot. Collectively, the rno_circRNA_016194 might be involved in formaldehyde-induced male reproductive toxicity and become potential therapeutic targets for male occupational exposure to formaldehyde.

RESUMO

An 18-month-old Angus bull presented to Auburn University College of Veterinary Medicine for a routine breeding soundness evaluation and lameness evaluation. He was classified as deferred potential breeder due to a lameness and was donated to the university. Following treatment, the bull's lameness resolved. He passed the breeding soundness examination in accordance with the Society for Theriogenology standards. However, avascular dilated areas at the level of the mediastinum testis of the right testicle were detected via Doppler ultrasonography. A high level of vascularity is routinely seen with neoplasia, such as teratomas. Due to the lack of vascularity, a presumptive diagnosis of tubular ectasia of the rete testis was made. The bull was castrated. The right testicle was submitted for histopathology revealing a definitive diagnosis of tubular ectasia of the rete testis.

RESUMO

Cancer treatment with cisplatin (CP) is associated with adverse side effects on male reproductive tissues. Although beneficial effects of zinc oxide nanoparticles (ZnO NPs) in cancer therapy have received considerable attention, data related to the protective effects of green ZnO NPs against CP-induced male reproductive dysfunctions are limited. Forty-five rats were divided into 9 groups including G1 (control), G2 (sham), G3 (ZnO bulk), G4 (green ZnO NPs), G5 (chemical ZnO NPs), G6 (CP), G7 (CP + ZnO bulk), G8 (CP + green ZnO NPs), and G9 (CP + chemical ZnO NPs). CP was administrated (5 mg/kg/week) for 4 weeks, and animals were simultaneously treated with different forms of ZnO (5 mg/kg/day). Testis histology, sperm parameters, oxidative stress markers, testosterone concentration, and expression of genes related in steroidogenesis were analyzed in different experimental groups. Testis tissue damage and epididymal sperm disorders induced by CP attenuated when animals were treated with different forms of ZnO, especially green ZnO NPs. Decreased testosterone concentration and increased MDA level in CP-treated rats were reversed following administration different forms of ZnO, especially green and chemical ZnO NPs. Co-administration of ZnO NPs to CP-treated rats restored the suppressive effects of CP on activities of antioxidant enzymes (SOD, GPX, CAT) and the transcription of the STAR gene. None of the ZnO forms had a significant regulatory effect on the expression of CYP11A1 in CP-treated rats. The results showed that in most of the evaluated factors, green ZnO NPs showed a greater protective effect than other forms of ZnO.

RESUMO

AIMS: Cadmium (Cd) is a prevalent environmental contaminant that incurs deleterious health effects, including testicular impairment. Sitagliptin, a selective dipeptidyl peptidase-4 (DPP-4) inhibitor, has demonstrated marked cardio-, hepato-, and reno-protective actions, however, its impact on Cd-triggered testicular dysfunction has not been formerly investigated. Hence, the present study aimed to explore the probable beneficial impact of sitagliptin against Cd-evoked testicular impairment which may add to its potential clinical utility. The underlying mechanisms pertaining to the balance between testicular autophagy and apoptosis were explored, including the AMPK/mTOR and Nrf2/HO-1 pathways. MATERIALS AND METHODS: The testicular tissues were examined using histopathology, immunohistochemistry, Western blotting, and ELISA. Sitagliptin (10 mg/kg/day, by gavage) was administered for 4 consecutive weeks. KEY FINDINGS: Sitagliptin attenuated the testicular impairment via improvement of the relative testicular weight, sperm count/motility, sperm abnormalities, and serum testosterone. Additionally, sitagliptin counteracted Cd-induced histologic aberrations/disrupted spermatogenesis. Interestingly, sitagliptin augmented the defective autophagy as demonstrated by upregulating Beclin 1 protein expression and lowering p62 SQSTM1 protein accumulation. These effects were mediated via the activation of testicular AMPK/mTOR pathway as proven by increasing p-AMPK (Ser485, Ser491)/total AMPK and diminishing p-mTOR (Ser2448)/total mTOR protein expression. Additionally, sitagliptin suppressed the testicular apoptotic events via downregulating Bax and upregulating Bcl-2 protein expression. In tandem, sitagliptin suppressed the oxidative stress through lowering lipid peroxides and activating Nrf2/HO-1 pathway via upregulating the protein expression of Nrf2, and the downstream effectors HO-1 and GPx. SIGNIFICANCE: Sitagliptin attenuated Cd-induced testicular injury via boosting the autophagy/apoptosis ratio through activation of AMPK/mTOR and Nrf2/HO-1 pathways.

RESUMO

BACKGROUND: Cisplatin is a chemotherapeutic drug used to treat testicular cancer that induces testicular toxicity. This study aimed to investigate the possible role of androgens, androgen receptor, and organic cation transporter 2 (OCT2) in the protective effects of curcumin on cisplatininduced testicular toxicity. METHODS: Thirty male Wistar rats were divided into five groups: 1- control (normal saline, 0.5 ml ip, daily for 10 consecutive days); 2- cisplatin (10 mg/kg ip, single dose at the first day); 3- cisplatin + curcumin (10 mg/kg ip, dissolved in 5% DMSO, daily for 10 consecutive days); 4- cisplatin + vehicle (DMSO 5%, 0.3 ml ip); and 5- curcumin (10 mg/kg ip). At the end of the study, a blood sample was obtained for testosterone measurement. The left testis was kept at -80. to measure androgen receptor (AR) and type 2 organic cation transporter (OCT2) gene expression and the right testis were kept in 10% formalin for histological analysis. RESULTS: Cisplatin significantly decreased serum testosterone, declined testis AR gene expression, and increased OCT2 gene expression in testis (p<0.01). Curcumin treatment significantly prevented these alterations in testosterone and gene expressions (p<0.01). Moreover, curcumin significantly reversed the cisplatin-induced kidney tissue injury and increased spermatid and spermatozoa. CONCLUSION: It is concluded that the ameliorative effect of curcumin in cisplatin-induced reproductive disorders was due to the modulation of testosterone and androgen receptors.

RESUMO

Immunoglobin-G4 related disease (IgG4-RD) is an auto-immune inflammatory condition where patients present with a tumour-like mass that shows infiltration by plasma cell and subsequent fibrosis. It is a systemic condition that primarily involves the salivary glands, pancreas, kidneys, aorta, and retroperitoneum amongst other organs. Testicular involvement is a rare occurrence in this disease entity. A 55-year old male patient presented with the complaints of pain and swelling in the right scrotal region. Right-sided orchidectomy was carried out which on histopathology showed features suggestive of IgG4-RD which was later confirmed on immunohistochemistry. Whole body MRI revealed that no other organ was involved in the disease process in this patient. IgG4-RD has a variable clinical course and considerable overlap with its differentials. Imaging studies and serum IgG4 levels are neither confirmatory nor customarily diagnostic in every case. The only confirmatory diagnostic investigation is histopathological examination, which shows infiltration of IgG4+ plasma cells and fibrosis in the involved tissue. Whenever a mass-forming lesion with typical histomorphological features is encountered with involvement of multiple organs/anatomic sites, IgG4-related disease should be considered among the differentials, and clinicians of all disciplines should be familiar with this disease entity.

RESUMO

We investigated the palliative effect of Artemisia judaica extract (AjE) on testicular deterioration induced by DM in high-fat diet/streptozocin (HFD/STZ)-injected rats. Forty rats were allocated to the following five groups: control, AjE, HFD/STZ, HFD/STZ-AjE, and HFD/STZ-metformin. HFD/STZ-diabetic rats showed a marked decrease in testicular weight and male sex hormones. There was significant suppression of testicular antioxidant enzymes and glutathione content in HFD/STZ-diabetic rats. However, rats that had received the STZ injection and the high-fat diet displayed increased malondialdehyde content and nitric oxide levels as well as tumour necrosis factor-alpha. High levels of Bax and low levels of Bcl-2 were detected after the STZ injection. Obvious pathological alterations were found in the testicular tissue of the HFD/STZ-diabetic rats. Thus, the administration of AjE attenuated the biochemical, molecular, and histopathological changes in the testes of the diabetic rats. The obtained findings showed that AjE treatment attenuated the diabetes-induced reprotoxicity in male rats via its antioxidant, anti-inflammatory, and antiapoptotic properties.
