Abstract
Testicular epidermoid cysts, accounting for 1%-2% of all testicular masses, present a diagnostic challenge often identified post-orchiectomy. Conservative surgery is recommended, emphasizing the need for accurate preoperative diagnosis. A 28-year-old patient with acute left scrotal pain, initially suggestive of testicular torsion, underwent intraoperative exploration revealing extra-vaginal torsion with an incidentally discovered 2-cm intra-testicular mass. Due to suspected malignancy, a total orchiectomy was performed. Pathological analysis confirmed an epidermoid cyst with normal postoperative tumor markers. The patient had a good postoperative outcome and underwent testicular prosthesis placement 3 months after the surgery. Epidermoid cysts, often identified incidentally during urgent scenarios, underscore the importance of accurate preoperative diagnosis. Conservative surgery remains the preferred approach, emphasizing the consideration of benign factors to prevent unnecessary orchiectomies.

Abstract
Zika virus (ZIKV) infection caused neurological complications and male infertility, leading to the accumulation of antigen-specific immune cells in immune-privileged organs (IPOs). Thus, it is important to understand the immunological responses to ZIKV in IPOs. We extensively investigated the ZIKV-specific T cell immunity in IPOs in Ifnar1-/- mice, based on an immunodominant epitope E294-302 tetramer. The distinct kinetics and functions of virus-specific CD8+ T cells infiltrated into different IPOs were characterized, with late elevation in the brain and spinal cord. Single epitope E294-302-specific T cells can account for 20-60% of the total CD8+ T cells in the brain, spinal cord, and testicle and persist for at least 90 days in the brain and spinal cord. The E294-302-specific TCRαβs within the IPOs are featured with the majority of clonotypes utilizing TRAV9N-3 paired with diverse TRBV chains, but with distinct αβ paired clonotypes in 7 and 30 days post-infection. Specific chemokine receptors, Ccr2 and Ccr5, were selectively expressed in the E294-302-specific CD8+ T cells within the brain and testicle, indicating an IPO-oriented migration of virus-specific CD8+ T cells after infection. Overall, this study adds to the understanding of virus-specific CD8+ T cell responses for controlling and clearing ZIKV infection in IPOs.IMPORTANCEThe immune-privileged organs (IPOs), such as the central nervous system and testicles, presented pathogenicity and inflammation after Zika virus (ZIKV) infection with infiltrated CD8+ T cells. Our data show that CD8+ T cells keep up with virus increases and decreases in immune-privileged organs. Furthermore, our study provides the first ex vivo comparative analyses of the composition and diversity related to TCRα/β clonotypes across anatomical sites and ZIKV infection phases. We show that the vast majority of TCRα/β clonotypes in tissues utilize TRAV9N-3 with conservation. Specific chemokine expression, including Ccr2 and Ccr5, was found to be selectively expressed in the E294-302-specific CD8+ T cells within the brain and testicle, indicating an IPO-oriented migration of the virus-specific CD8+ T cells after the infection. Our study adds insights into the anti-viral immunological characterization and chemotaxis mechanism of virus-specific CD8+ T cells after ZIKV infection in different IPOs.

Abstract
OBJECTIVE To study compensatory changes in testicular growth and the hormonal axis after unilateral orchiectomy in a neonatal, prepubertal, and pubertal/adult murine model. This is the first study to use a neonatal mouse survival surgery model. DESIGN A laboratory-based study examining a control, neonatal, prepubertal, and pubertal/adult mouse model. SETTING University-based basic science research laboratory. ANIMALS Control, neonatal (2-4 days of life), prepubertal (12-21 days of life), and pubertal/adult (42-44 days of life) C57BL/6 mouse models. INTERVENTION Unilateral orchiectomy in the neonatal, prepubertal, and pubertal/adult mouse models at their respective ages. MAIN OUTCOME MEASURES Body and testis weight and testicular length in the long axis were measured in a blinded fashion. In a similar way, testosterone, luteinizing hormone (LH), and follicle-stimulating hormone were assessed. RESULTS Testes from neonatal and prepubertal mice weighed more (110.5, 12.2 and 103.0, 7.2 mg, respectively) than the control mice (91, 11.9 mg). There was no difference between the postpubertal group and the control group. The degree of compensatory hypertrophy was greater in the neonatal group but not in the prepubertal group when compared with the postpubertal group. Differences in follicle-stimulating hormone and testosterone were not statistically significant between the experimental and control arms. LH was significantly elevated in all experimental groups compared with the control. CONCLUSIONS This is the first study to assess testicular compensatory hypertrophy using a neonatal mouse survival surgery model. Testicular hypertrophy occurs when unilateral loss occurs before puberty, but not in adulthood in mice. Earlier testis loss may contribute to a greater degree of growth. Functionally, the unilateral testis can maintain eugonadal testosterone levels, but higher levels of LH are required after hemicastration to sustain eugonadal testosterone levels.

Abstract
Testicular mucinous cystadenoma is a rare benign testicular tumor with the characteristics of being potentially malignant and showing atypical clinical symptoms; this article reports a case of a primary testicular mucinous cystadenoma misdiagnosed as testicular teratoma by ultrasound. A 69-year-old man was admitted to the hospital because of a 1-year history of left-sided testicular enlargement with scrotal swelling and no obvious abnormalities on laboratory tests. Ultrasound examination revealed solid-mass lesions in the left testicle, suggesting a high probability of teratoma, and contrast-enhanced magnetic resonance imaging (MRI) examination suggested an increased possibility of epidermoid cysts. Contrast-enhanced computed tomography (CT) and contrast-enhanced MRI of the preoperative abdomen and pelvis showed no other primary adenocarcinoma. Doctors performed radical resection of the left testicle. The postoperative pathological diagnosis was mucinous cystadenoma, and calcification as well as partially mildly atypical epithelial cells were discovered. Furthermore, there were no neoplastic lesions in the epididymis or spermatic cord. No metastatic lesions were found after 6 months postoperative follow-up, and the patient's prognosis remains good.

Abstract
BACKGROUND Rabbits are sensitive to dietary cholesterol and rapidly develop hypercholesterolemia, leading to prominent subfertility. Sterol regulatory element-binding protein isoform 2 drives the intracellular cholesterol pathway in many tissues, including the testicles. Its abnormal regulation could be the mainly responsible for the failure of suppressing cholesterol synthesis in a cholesterol-enriched environment, ultimately leading to testicular and seminal alterations. However, extra-virgin olive oil consumption has beneficial properties that promote lowering of cholesterol levels, including the recovery of seminal parameters altered under a high-fat diet. OBJECTIVES Our goal was to investigate the effects of high-fat diet supplementation with extra-virgin olive oil at the molecular level on rabbit testes, by analyzing sterol regulatory element-binding protein isoform 2 protein and its corresponding downstream effectors. MATERIALS AND METHODS During 12 months, male rabbits were fed a control diet, high-fat diet, or 6-month high-fat diet followed by 6-month high-fat diet plus extra-virgin olive oil. Serum lipids, testosterone levels, bodyweight, and seminal parameters were tested. The mRNA and protein levels of sterol regulatory element-binding protein isoform 2, 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase, and low-density lipoprotein receptor were determined by semi-quantitative polymerase chain reaction and Western blotting techniques. The expression pattern of sterol regulatory element-binding protein isoform 2 protein in the rabbit testicles was studied by indirect immunofluorescence. In addition, testicular cholesterol was detected and quantified by filipin staining and gas chromatography. RESULTS The data showed that the addition of extra-virgin olive oil to high-fat diet reduced testicular cholesterol levels and recovered the expression of sterol regulatory element-binding protein isoform 2, 3-hydroxy-3-methyl-glutaryl-coenzyme A reductase, and low-density lipoprotein receptor initially altered by the high-fat diet. DISCUSSION AND CONCLUSIONS The combination of high-fat diet with extra-virgin olive oil encourages testicular recovery by modifying the expression of the enzymes related to intracellular cholesterol management.

Abstract
PURPOSE To assess the possible influence of the presence of varicocele on the quantification of testicular stiffness. METHODS Ultrasound with shear wave elastography (SWE) was performed on 48 consecutive patients (96 testicles) referred following urology consultation for different reasons. A total of 94 testes were studied and distributed in three groups: testes with varicocele (group A, n = 19), contralateral normal testes (group B; n = 13) and control group (group C, n = 62). Age, testicular volume and testicular parenchymal tissue stiffness values of the three groups were compared using the Kruskal-Wallis test. RESULTS The mean age of the patients was 42.1 ± 11.1 years. The main reason for consultation was infertility (64.6%). The mean SWE value was 4 ± 0.4 kPa (kilopascal) in group A, 4 ± 0.5 kPa in group B and 4.2 ± 0.7 kPa in group C or control. The testicular volume was 15.8 ± 3.8 mL in group A, 16 ± 4.3 mL in group B and 16.4 ± 5.9 mL in group C. No statistically significant differences were found between the three groups in terms of age, testicular volume and tissue stiffness values. CONCLUSION Tissue stiffness values were higher in our control group (healthy testicles) than in patients with varicocele.

Abstract
The objective of this study was to investigate whether treatment with Tribulus terrestris (Tt) has any impact on the testicular morphology and function in a rodent model. Twenty male rats were divided into a control group and a group receiving 100 mg kg-1 body weight of Tt supplementation. After 40 days of experiment, the animals were submitted to euthanasia; epididymal tail spermatozoa were collected; and spermatozoa concentration, motility, and viability were analyzed. In addition, testicles were collected and processed for histomorphometrical analyses. Data were compared using the Student's t-test and considered significant when P < 0.05. Spermatozoa concentration, motility, and viability showed no difference between the groups. Further, testicular weight and volume, seminiferous tubule diameter, tunica propria surface density, seminiferous epithelium surface density, and intertubular compartment surface density were statistically similar between the groups. However, seminiferous epithelium height and tubular lumen surface density were augmented in animals treated with Tt. Treatment with Tt does not cause a major impact on testicular morphology, promoting only subtle modifications. No difference on spermatozoa parameters was observed.

Abstract
Testicular rupture is a surgical emergency necessitating prompt diagnosis and intervention to prevent irreversible damage. Blunt trauma, including motorcycle collisions, is a common cause of testicular rupture. In the case of multi-trauma, the diagnosis of testicular rupture may be missed in the rush to surgical intervention of more grossly obvious injuries. We present a case of a 24-year-old male who suffered a motorcycle accident and subsequently presented with diffuse abdominal and hip pain. Physical exam and imaging at the emergency department showed multiple pelvic bone fractures, along with a small scrotal injury which was triaged below his pelvic injuries. His pelvic fractures were immediately operated on. Nearly 18 hours after his initial presentation, the patient received a scrotal ultrasound which demonstrated a rupture of the right testicle. Due to this long delay in diagnosis, his urological team opted for non-surgical management and instead employed a more conservative treatment regimen involving pain control, scrotal support, rest, and serial scrotal ultrasounds. This case highlights the importance of timely ultrasound examination for testicular pathology in the setting of multi-trauma and known scrotal injury. Another highlight of this case is the showcase of an uncommon treatment regimen utilizing conservative tactics as opposed to opting for surgical intervention.

Abstract
Testicular torsion is a frequently encountered clinical condition that requires urgent treatment. The aim of this study is to investigate the efficacy of Anise (Pimpinella anisum L.) in treating the pathological condition due to ischemia and reperfusion injury by using biochemical, histopathological and immunohistochemical methods. A total of 6 groups were formed with 8 male Wistar Albino rats in each group. Group 1 (n=8): control group, Group 2 (n=8): Anise aqueous solution was given orally 5 ml/kg by gavage for 30 days. Group 3 (n=8): Ischemia and Reperfusion (I/R) group, bilateral testicles were rotated 270° and reperfused after 30 minutes of ischemia. Group 4 (n=8): I/R+ Anise group, Group 5 (n=8): Anise+ I/R group and Group 6 (n=8): Anise+ I/R+ Anise group. The results of the Anise group and the Control group were similar. However, the damage in the I/R group was considerably more severe than in any of the other study groups. While it was observed that spermatogenic cells started to regenerate in the I/R+Anise group, edema and congestion were observed in the Anise+I/R group. In the Anise+I/R+Anise group, all histological findings and biochemical parameters were similar to those of the control group. It was observed that anise had protective effects in ischemia and reperfusion injury in rat testicles.

Abstract
Leiomyomas are benign, slow-growing, mesenchymal neoplasms that originate from smooth muscle. We report a case of a 44-year-old man presented with an asymptomatic left scrotal mass. Scrotal ultrasonography (US) showed a 3.9 cm well-limited, hypoechoic intratesticular mass. The patient underwent a radical left orchiectomy and histologic findings revealed an intratesticular leiomyoma. To our best knowledge, so far, this is the 19th case of intratesticular leiomyoma to be reported in the literature. Furthermore, intraoperative frozen section examination should have been part of the management armamentarium in this case, leading to enhanced testicular preservation.

Abstract
The hepatitis E virus (HEV) is the main cause of viral acute hepatitis in the world, affecting more than 20 million people annually. During the acute phase of infection, HEV can be detected in various body fluids, which has a significant impact in terms of transmission, diagnosis or extrahepatic manifestations. Several studies have isolated HEV in the genitourinary tract of humans and animals, which could have important clinical and epidemiological implications. So, our main objective was to evaluate the presence of HEV in testis of naturally infected wild boars (Sus scrofa). For it, blood, liver, hepatic lymph node and testicle samples were collected from 191 male wild boars. The presence of HEV was evaluated in serum by PCR, as well as in tissues by PCR and immunohistochemistry. Four animals (2.09%; 95%CI: 0.82-5.26) showed detectable HEV RNA in serum, being confirmed the presence of HEV-3f genotype in three of them by phylogenetic analysis. HEV was also detected in liver and/or hepatic lymph nodes of the four animals by RT-PCR, as well as by immunohistochemistry analysis. Only one of these wild boars also showed detectable viral load in testis, observing HEV-specific labelling in a small number of fibroblasts and some Sertoli cells. Our results confirm the presence of HEV genotype 3 in naturally infected wild boar testis, although no associated tissue damage was evidenced. This study does not allow us to discard semen as a possible source of HEV transmission in suids. Future experimental studies are necessary to evaluate the impact of HEV genotype 3 on fertility and the possibility of transmission through sexual contact in this specie.

Abstract
Objective: To investigate the effects of cadmium (Cd) on antioxidant enzymes in testis of mice and the protective effect of vitamin C (VC). Methods: A total of 72 male Kunming mice of clean grade were divided into four groups (n=18): the control group, the Cd group (CdCl2 3 mg/kg), the VC group (200 mg/kg), and the VC (200 mg/kg) +Cd group (CdCl2 3 mg/kg). Mice were poisoned once a day, exposed for 1 and 3 days and were treated with VC at the same time. Twenty-four hours after exposure on the 1st and 3rd day, half of the mice in each group were weighed, the serum and testis tissues were collected. Testicular organ coefficient, malondialdehyde (MDA) and superoxide dismutase (SOD) in serum and testis tissues, and glutathione peroxidase (GSH-Px), reduced glutathione (GSH), oxidized glutathione (GSSG) and total glutathione (T-GSH) in testis tissues were detected. Results: Compared with the control group, the body weight and testicle organ coefficient of mice in the Cd group were decreased on the 1st and 3rd day; after 3 days of exposure, the serum SOD in the Cd group was decreased significantly and MDA was increased significantly (P<0.05); the levels of SOD, GSH-Px, T-GSH and GSH/GSSG of testis in the Cd group were increased significantly on the 1st day (P<0.05), while all the above indexes were decreased significantly on the 3rd day (P<0.05), and the content of MDA was increased significantly on the 1st and 3rd days in the Cd group (P<0.05); after VC treatment, the degree of reduction was decreased. Compared with the Cd group, the serum SOD and MDA levels in the VC+ Cd group were significantly different after 3 days of exposure (P<0.05); the changes of SOD, GSH-Px, T-GSH and GSH/GSSG levels of the testis in the VC+ Cd group were significantly different on the 1st and 3rd day of exposure (P<0.05), and the MDA level of the testis in the VC+ Cd group was decreased significantly on the 3rd day of exposure (P<0.05). Compared with the Cd group for 1 day, the level of serum SOD exposed for 3 days was decreased significantly (P<0.05), and the changes of testis indexes were also significantly different (P<0.05). Conclusion: VC treatment can improve the antioxidant function of cadmium-loaded mice to some extent, and has protective effect on oxidative damage of testis.

Abstract
Varicocele (VCL) is a pathological dilation of the venous pampiniform plexus of the spermatic cord and is also classified as male factor infertility. The current experiment aimed to examine the protective effect of Fumaria parviflora (FP), as a powerful antioxidant, against reproductive damage induced by VCL. In this experimental study, 32 male rats were randomly allocated into four groups, namely sham (simple laparotomy without additional intervention), FP (healthy rats administered 250 mg/kg FP), VCL + FP (underwent VCL and received 250 mg/kg FP), VCL (underwent VCL without receiving any treatment). The results showed that the number of Sertoli and germ cells were markedly reduced in the VCL group in comparison to the FP-treated and sham groups. The VCl + FP group had significantly higher serum levels of testosterone (T), FSH, and LH hormones than the VCL group. The quality and motility of spermatozoa were reduced in the VCL group compared with other groups (p ≤ 0.05). Moreover, our findings demonstrated that the administration of FP considerably enhanced the mRNA levels of CatSper-1 and -2, SF-1, 3β-HSD, 17β-HSD3, LHCGR, and FSHR (p ≤ 0.05). Based on the obtained results, treatment with FP is capable of preventing testicular dysfunction and elevating the concentration of hormones and some crucial genes, such as CatSper1 and 2, SF-1, 3β-HSD, 17β-HSD3, LHCGR, and FSHR that contribute to the spermatogenesis process.

Abstract
BACKGROUND The role of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the pathogenesis of testicular damage is uncertain. METHODS We investigated the virological, pathological, and immunological changes in testes of hamsters challenged by wild-type SARS-CoV-2 and its variants with intranasal or direct testicular inoculation using influenza virus A(H1N1)pdm09 as control. RESULTS Besides self-limiting respiratory tract infection, intranasal SARS-CoV-2 challenge caused acute decrease in sperm count, serum testosterone and inhibin B at 4-7 days after infection; and chronic reduction in testicular size and weight, and serum sex hormone at 42-120 days after infection. Acute histopathological damage with worsening degree of testicular inflammation, hemorrhage, necrosis, degeneration of seminiferous tubules, and disruption of orderly spermatogenesis were seen with increasing virus inoculum. Degeneration and death of Sertoli and Leydig cells were found. Although viral loads and SARS-CoV-2 nucleocapsid protein expression were markedly lower in testicular than in lung tissues, direct intratesticular injection of SARS-CoV-2 demonstrated nucleocapsid expressing interstitial cells and epididymal epithelial cells, While intranasal or intratesticular challenge by A(H1N1)pdm09 control showed no testicular infection or damage. From 7 to 120 days after infection, degeneration and apoptosis of seminiferous tubules, immune complex deposition, and depletion of spermatogenic cell and spermatozoa persisted. Intranasal challenge with Omicron and Delta variants could also induce similar testicular changes. This testicular damage can be prevented by vaccination. CONCLUSIONS SARS-CoV-2 can cause acute testicular damage with subsequent chronic asymmetric testicular atrophy and associated hormonal changes despite a self-limiting pneumonia in hamsters. Awareness of possible hypogonadism and subfertility is important in managing convalescent coronavirus disease 2019 in men.

Abstract
Testicular replantation represents a unique circumstance. There are very few reports documenting their experience with testicle replantation and to the best of the authors' knowledge, this is the first case that has been reported in the peer-reviewed literature following a wrong site surgery. Therefore, we detail our technique and outcome when faced with such a rare event. In addition we review the literature, in order to compare and report the experience of others. This case highlights the value of applied microsurgical knowledge and the importance of cross-disciplinary efforts to improve patient outcomes.

Abstract
Medullary bone is a calcium-rich, labile bone normally occurring in female birds with each egg-laying cycle. The stimulus for formation of medullary bone is, in part, the cyclic increase in serum estrogens produced by preovulatory ovarian follicles. Increased bone density due to formation of medullary bone, particularly in pneumatic bones, has been termed polyostotic hyperostosis, even if physiologic. This study investigated the formation of medullary bone in nonpneumatic (femur) and pneumatic (humerus) bones in sexually mature male budgerigars submitted for autopsy. Of the 21 sexually mature male budgerigars submitted for autopsy, 7 (33%) had medullary bone in 1 or more bones examined. All 7 male budgerigars with medullary bone had a testicular neoplasm, which was morphologically consistent with a testicular sustentacular cell tumor, seminoma, or interstitial cell tumor. Medullary bone was not present in the 14 cases with other diseases. Medullary bone formation in pneumatic and nonpneumatic bones can occur in male budgerigars with testicular neoplasms. Radiographic increases in medullary bone density, particularly in the humerus, could provide antemortem indication of testicular neoplasia in male budgerigars.

Abstract
Cystic dysplasia of the rete testis (CDRT) is a rare cause of testicular masses in children. The pathogenesis of this malformation remains unclear. It is often associated with other genitourinary anomalies, commonly presenting as agenesis or dysplasia of the ipsilateral kidney. A case involving a 9-year-old boy with a testicular lesion and ipsilateral renal agenesis, who was diagnosed with CDRT after histological examination, is reported. In addition, a systematic review of the literature was performed to better understand this pathology to design the most appropriate treatment and follow-up strategy for patients with CDRT.

Abstract
The aim of this study was to describe the histological effects of two high postnatal doses of the potent third-generation GnRH antagonist, acyline in the domestic cat testicle. Secondly, the physical, endocrine, and steroidogenic findings of this pharmaceutical protocol are also reported. Twelve postnatal littermate male kittens were administered acyline in a dose of 2.2 mg/100 g SC weekly for 2 weeks (ACY; n = 6), or placebo (PL; n = 6). All the animals were followed up until puberty when they were castrated. Serial faecal samples were collected until the age of 10 weeks for testosterone (T) measurement. The kittens achieved puberty without either age (236.5 ± 19.7 vs. 221.7 ± 23.7 days) or body weight (3.05 ± 0.15 vs. 2.78 ± 0.28 kg, P > 0.05) differences between ACY and PL, respectively. Acyline suppressed faecal T concentrations for 3 weeks (P < 0.01). From the fourth week on, both groups had low concentrations up to the end of the follow-up period (P > 0.05). Histological assessment of the testes showed that ACY cats presented a reduced height of the epithelium (P < 0.01) due to the diminished number of germinal cells accompanied by an enlarged luminal area (P < 0.01) with cellular debris (P < 0.01). The immunostaining of P450c17 also appeared partially diminished in ACY testes.

Abstract
Seminoma is reported as a rare disease associated with specific micro‐morphologic findings. In the present report, we describe the case of a testicular seminoma in a 7‐year‐old Holland Lop rabbit, in which the cytology presented an atypical pattern. Upon presentation, the left testicle was severely enlarged, and the patient also had a history of radiation therapy for a previously diagnosed thymoma. Following excision and histopathology of the abnormal organ, results showed a mixed intratubular‐diffuse pattern with evidence of torsion. Moreover, cytology revealed a cohesive pattern with multiple malignancy criteria. To our knowledge, this is the first published report of a seminoma with these cytologic features.

Abstract
Supplemental Digital Content is available in the text Microbiome is of upmost importance for the well-being of the human body. Based on culture and PCR methods, seminal flora has been pointed as a potential cause for some of the unexplained male infertility. This is a systematic review about the effect of seminal microbiota studied by Next Generation Sequencing techniques on sperm quality and male fertility, performed according to PRISMA statement. Nine articles were included. Results of different studies are diverse. It seems that microbiota may a play a role in seminal quality and further male fertility, but the way this effect is modulated is still to be unknown. Lactobacillus spp seemed to play a beneficial role in semen quality, but the role of the remaining bacteria is unclear. Due to the lack of research and the incongruence of the results so far, the effect of microbiota on seminal quality is still unclear.

Abstract
It has been proposed that men hospitalised with COVID-19 be treated with oestrogen or progesterone to improve COVID-19 outcomes. Transgender women (male-to-female) are routinely treated with oestrogen or oestrogen +progesterone for feminisation which provides a model for the effect of feminising hormones on testicular tissue. Our goal was to analyse differences in ACE-2 expression in testicles of trans-women taking oestrogen or oestrogen +progesterone. Orchiectomy specimens were collected from trans-women undergoing gender-affirming surgery, who were taking oestrogen or oestrogen+progesterone preoperatively. For controls, we used benign orchiectomy specimens from cis-gender men. All specimens were stained with H&E, Trichrome (fibrosis), insulin-like 3 antibody (Leydig cell) and ACE-2 IHC. Cells per high-powered field were counted by cell type (Leydig, Sertoli and Germ). Stain intensity was rated on a 0-2 scale. On immunohistochemistry staining for Leydig cells and ACE-2 staining, the oestrogen+progesterone cohort had fewer Leydig cells compared with controls. The oestrogen+progesterone cohort also had greater degree of tissue fibrosis compared with controls and the oestrogen cohort. This work supports the hopeful possibility that a short course of progesterone (or oestrogen+progesterone) could downregulate ACE-2 to protect men from COVID-19 infection.

Abstract
The normal developmental anatomy and histology of the reproductive tract of the honey bee drone, Apis mellifera (Linnaeus, 1758), has been well documented. The post-emergence maturation changes of the accessory glands are likewise well understood, but the normal histological changes of the testicle undergoing physiologic atrophy are not well characterized. To address this knowledge gap, herein we describe the anatomy and sequential histological stages of normal testicular atrophy of drones sampled daily from emergence to sexual maturity in the spring (June) and early summer (July). Testicular histological changes during maturation are characterized by the following stages: I) conclusion of spermiogenesis; II) evacuation of spermatodesms from tubular lumens; III) progressive follicular cell atrophy, and IV) complete atrophy and collapse of testicular parenchyma. Tubular changes occur in a basilar to apical direction where segments closer to the vas deferens are histologically more mature than corresponding apical segments. In addition, the rate of testicular maturation was found to change with seasonal progression. This description of physiologic testicular atrophy should be useful for future studies investigating potential pathological effects of stressors on drone testes during sexual maturation.

Abstract
Objective: To investigate the effects of different doses of ketoconazole (KCZ) on the physiological functions of the liver and testis in Kunming mice. Methods: Forty male Kunming mice were randomly divided into four groups (n=10): normal group, KCZ low-dose group (30 mg/kg), medium-dose group (50 mg/kg), and high-dose group (70 mg/kg). The mice in the drug groups were injected subcutaneously (0.1 ml/10 g) with the corresponding dose of KCZ once a day, and the concentrations of KCZ in the KCZ low, middle, and high dose groups were 3 mg/ml, 5 mg/ml and 7 mg/ml respectively, and the normal group was injected with the same amount of normal saline for 3 weeks. The activities of aspartate transaminase (AST) and alanine aminotransferase (ALT) in serum, and γ-glutamyl transpeptidase (γ-GT), lactate dehydrogenase (LDH) and acid phosphatase (ACP) in testicular tissue were measured. HE staining was used to observe the pathological changes of the liver and testis. Results: Compared with the normal group, the activities of AST and ALT were increased significantly (P<0.01), and the activities of γ-GT, ACP and LDH were decreased markedly in KCZ groups (P<0.01). KCZ could affect the above indexes in a dose-dependent manner. HE staining showed that the hepatocytes were denatured, arranged loosely, and the cytoplasm was light in color. The lumen of the seminiferous tubules of the testis were enlarged, and the number of spermatogenic cells and sperm at all levels were decreased. Conclusion: KCZ could cause physiological function damage and pathological histological changes of the liver and testis, increase the levels of liver transaminase, reduce the activities of testicular specific enzymes of mice. Besides, the degree of damage was increased with the increase of dose.

Abstract
Reptiles are highly susceptible to anthropogenic activities as a result of their narrow geographical ranges and habitat specialization, making them a conservation concern. Geckos represent one of the mega-diverse reptile lineages under pressure; however, limited assisted reproductive technologies currently exist for these animals. Exogenous pregnant mare serum gonadotropin (PMSG) has been found to exhibit follicle stimulating hormone-like action and has been routinely used to alter reproductive hormones of vertebrates in assisted reproductive protocols. The purpose of this study was to determine the effects of serial injections of 20 IU and 50 IU PMSG on circulating testosterone concentrations, testicular dynamics, and semen production in a model species of gecko. Twenty-four captive-bred, adult, male leopard geckos (Eublepharis macularius) were divided into three treatment groups and administered a once-weekly injection of either PMSG or saline for a total of nine weeks. Ultrasonographic testicular measurements, electrostimulation for semen collection, and venipuncture were performed on days 0, 21, 42, and 63. Right unilateral orchidectomies and epididymectomies were performed in all animals on day 63; tissues were submitted for histopathology. PMSG treated geckos had significantly higher testicular volumes and weights, spermatozoa motility, and spermatozoa concentrations compared with controls. However, there were no significant differences in testosterone concentrations by treatment or time. Under the conditions outlined, PMSG is effective at stimulating spermatogenesis and increasing testicular size, but not effective at increasing testosterone concentrations in the leopard gecko between October-December in the Northern hemisphere.

Abstract
Testicular vitrification is an alternative to preserve the genetic material of pre-pubertal animals. However, there are few studies on post-vitrification warming. Hence, the aim was to compare the influence of different warming temperatures on vitrified testicular fragments from pre-pubertal cats. The testicles were fragmented and divided into a control group (non-vitrified) and vitrified, using an association between dimethylsulphoxide and glycerol. The vitrified fragments were warmed at 50, 55 and 60°C/5 s. Morphological and morphometric evaluations were carried out using classical histology. Afterwards, the mitochondrial activity was evaluated using Rhodamine 123. The data were expressed in mean and standard error. The differences were considered significant when p < .05. In the histomorphological analysis, the testicular fragment presented seminiferous tubules with poorly developed germinal epithelium, compatible with pre-pubertal animals. The group warmed at 50°C presented similar to the control regarding the maintenance of the integrity of the tubules and cells, without stromal rupture and lamina propria alteration, as well as regarding the maintenance of the junctions between the cells. The group warmed at 55°C showed reduction of the cell junctions, and the one warmed at 60°C had increased detachment of the basement membrane (p < .05). The warming caused a reduction in the tubular diameter inversely proportional and progressive to the increase in temperature, with the highest diameter in the control group and the lowest in the 60°C group. The control group showed a lower incidence of Rhodamine 123, followed in ascending order of the warmings at 55 and 60°C. The higher mitochondrial activity was obtained with 50°C, showing an increase of the metabolic cell function at this temperature. It was concluded that the testicular fragment of pre-pubertal cats presents a better preserved morphology, morphometry and viability when warmed at 50°C.

Abstract
This study is to identify the differentially expressed miRNAs in testicular tissues of rats with hyperuricaemia-induced male infertility. We found that the hyperuricaemia model group had significantly increased serum uric acid, while significantly decreased sperm concentration and motile sperm percentage than normal group (p < .05). A total of 39 differentially expressed miRNAs were identified in the testicular tissues of hyperuricaemia rats compared with the control rats, ten of which were validated by real-time PCR. The target mRNAs of 7 differentially expressed miRNAs (miR-10b-5p, miR-26a-5p, miR-136-5p, miR-151-3p, miR-183-5p, miR-362-3p and miR-509-5p) from 3'-untranslated region binding perspective were enriched in signalling pathways of Wnt, Jak-STAT, mTOR and MAPK. The target mRNAs of 6 differentially expressed miRNAs (miR-136-5p, miR-144-3p, miR-99a-5p, miR-509-5p, miR-451-5p and miR-362-3p) from coding sequence binding perspective were enriched in signalling pathways of Calcium, Notch and MAPK. The functions of miRNAs in testicular tissues of rats with hyperuricaemia were revealed by the differentially expressed miRNAs (miR-183-5p, miR-99a-5p, miR-10b-5p, miR-151-3p, miR-26a-5p, miR-451-5p, miR-362-3p, miR-136-5p, miR-144-3p and miR-509-5p)-mRNAs interaction network. The differentially expressed miRNAs in the testicular tissues of hyperuricaemia rats might shed light on the mechanism of hyperuricaemia-induced male infertility.

Abstract
Early weaning can lead to changes in the morphology of organs in adulthood, and the consumption of functional foods during lactation and postnatal life is believed to prevent these changes. However, it is not known if early weaning affects testicular morphology and if the use of cocoa can prevent that. We studied the effects of maternal and postnatal supplementation of cocoa powder on the testicular morphology of early weaned adult rats. The animals were divided into four groups (n = 6 each), control group, cocoa control group, early weaning (EW) group, and cocoa early weaning (EWCa) group, and were analyzed for 90 d, after which they were euthanized. The animals from the EW group showed a reduction in the tubular diameter and height of the seminiferous epithelium, a decrease in epithelial surface density (Sv), and an increase in the lumen and proper tunic. However, the animals from the EWCa group showed an increase in the diameter and height of the epithelium, an increase in the epithelium Sv, and a decrease in the lumen and the proper tunic. The early weaning promotes morphological changes in the testicles; however, supplementation with cocoa powder can preserve the testicular histoarchitecture.

Abstract
Chronic orchialgia can be the result of pathological processes of the scrotal contents or stem from non-intrascrotal structures. Successful pain management depends on identifying the source of localized or referred pain. This is a case report of a 39-year-old male sports coach who presented with low back pain, right orchialgia, and sciatica refractory to conservative management. Magnetic resonance (MR) imaging revealed disc protrusion at L3/L4 and L4/L5 levels. Positive outcomes in relieving back and testicular pain were obtained after a total of 30 chiropractic sessions over a 9-week period. The evidence of the subjective improvement was corroborated by regression of the herniated discs documented on the repeat MR imaging. While chronic orchialgia is not an uncommon problem for men of all ages, it has seldom been described in association with lumbar discogenic disease. The current study provided preliminary support for a link between orchialgia and lumbar disc herniation. Chiropractic manipulation had provided a mechanistic alleviation of noxious lumbar stimuli, leading to symptomatic and functional improvements.

Abstract
Teratoma is a rare germ cell testicular cancer composed of cells that are not normally present in the site where it originates. These tumors are rarely described in horses, where they may develop due to cryptorchidism. Teratomas consist of cells originating from different germinal layers, arising from germinal multi-potential cells with differentiation defects, and can simultaneously contain several tissues from two or more embryonic layers. Testicular teratomas are described in horses, cats, dogs, wild boars, bulls, and humans. In the rare descriptions found in literature of testicular teratoma in stallions, they occur frequently in cryptorchid testicles, as a consequence of congenital neoplasm. To our knowledge there is no other report of a dentigerous equine teratoma in a stallion. We describe here a successful laparoscopic removal of a testicular teratoma and its clinic-pathological features.

Abstract
OBJECTIVE. Knowledge of normal testicular 18F-FDG PET/CT (FDG PET/CT) SUVs is crucial for accurate examination interpretation. The objective of this study was to establish normal testicular SUV ranges among adult men receiving health care in North America. MATERIALS AND METHODS. A retrospective review of an institutional electronic database identified adult men undergoing pretreatment clinical FDG PET/CT examinations from March 15, 2013, through March 15, 2018. An FDG PET/CT image review of 700 testicles in 350 male patients was performed. Data collected included testicular SUVmax, SUVmean, and visual PET pattern of uptake. RESULTS. Testicular SUVmean and SUVmax values (mean ± SD) by age group were as follows: 3.1 ± 0.7 and 3.8 ± 0.9 for the age group of 18-30 years; 3.2 ± 0.6 and 4.0 ± 0.8, 31-40 years; 3.1 ± 0.4 and 3.8 ± 0.5, 41-50 years; 3.0 ± 0.5 and 3.7 ± 0.7, 51-60 years; 2.9 ± 0.5 and 3.5 ± 0.7, 61-70 years; 2.8 ± 0.5 and 3.5 ± 0.7, 71-80 years; and 2.6 ± 0.5 and 3.3 ± 0.6, more than 80 years. A statistically significant difference exists between age groups for testicular SUVmean (p ≤ .001) and SUVmax (p < .001), with SUVs peaking in the 4th decade of life and subsequently declining with age. A small but significant negative correlation exists between blood glucose level and testicular SUVmean (r = -0.12). CONCLUSION. This study reports the largest currently known cohort of SUVs in normal testicles and may guide clinical interpretation of testicular FDG activity. Discrepancies in normal SUVs may exist because of differences in patient demographics and PET technology.

Abstract
Scrotal and testicular injuries are uncommon injuries, accounting for only a fraction of all trauma. Blunt scrotal trauma is accompanied by testicular rupture in up to 50% of cases. We present a rare case of scrotal rupture with evisceration of a viable, intact testicle after a motor vehicle accident. The patient’s presentation, associated injuries, operation, and post-operative course are described. In brief, this is a case of a 69-year-old male who sustained multiple rib, pelvic, and right femur fractures in addition to scrotal injury after a motor vehicle accident. He was taken quickly to the operating room for the scrotal rupture, and his testicle was successfully replaced and scrotal laceration repaired. He did well post-operatively. This case represents one of the few accounts of this particular injury in the literature.

Abstract
BACKGROUND Platelet-rich plasma is a biological instrument rich in growth factors and cytokines. OBJECTIVES The aim of this study was to investigate the effect of platelet-rich plasma on spermatogenesis and hormone production in an experimental testicular torsion model. MATERIALS AND METHODS The rats were randomly divided into three groups, including six rats in each group as follows: the first group as the sham group; the second group as the ischemia/reperfusion + Saline group and the third group as the ischemia/reperfusion + platelet-rich plasma group. The left testicles of the ischemia/reperfusion + Saline and ischemia/reperfusion + platelet-rich plasma group were kept in four-hour torsion. Then, the left testicles of ischemia/reperfusion + Saline and ischemia/reperfusion + platelet-rich plasma groups were detorsioned, and intra-testicular 1 cc saline (ischemia/reperfusion + Saline) and 1 cc platelet-rich plasma (ischemia/reperfusion + platelet-rich plasma) were injected. At one month, blood samples were taken from all groups for hormonal evaluation and left orchiectomy was performed. RESULTS The mean follicle-stimulating hormone level of ischemia/reperfusion + Saline group was significantly higher than ischemia/reperfusion + platelet-rich plasma group (7.78 ± 0.23 vs 6.18 ± 0.28 nmol/l, respectively, P = .004). The mean LH level of ischemia/reperfusion + platelet-rich plasma group was significantly lower than ischemia/reperfusion + Saline group (3.63 ± 0.28 vs 5.68 ± 0.21 nmol/l, respectively, P = .004). The mean total testosterone level of ischemia/reperfusion + platelet-rich plasma group was significantly higher than ischemia/reperfusion + Saline group (8.05 ± 0.24 vs 5.78 ± 0.23 nmol/l, respectively, P = .004). The mean Johnsen scores of ischemia/reperfusion + platelet-rich plasma group were significantly higher than ischemia/reperfusion + Saline group (5.85 ± 0.58 vs 3.93 ± 0.65, respectively, P = .004). The mean Johnsen score of the sham group was significantly higher than ischemia/reperfusion + platelet-rich plasma and ischemia/reperfusion + Saline groups (P = .003 and P = .003, respectively). DISCUSSION AND CONCLUSION The platelet-rich plasma has beneficial effects on spermatogenesis and reproductive hormone production in testicular torsion. It is easily accessible and applicable. In the future, intra-testicular platelet-rich plasma injection may be used in testicular torsion after detorsion. However, further experimental and large-scale prospective clinical studies are needed to establish a definitive conclusion on this topic.

Abstract
Epidermoid cysts, which constitute 1% of all testicular tumors, are considered to be benign even though histogenesis is not clear. Patients usually suffer from painless scrotal mass or this mass is realized during the routine physical examination. Hematospermia may be a finding for both benign and malignant testicular tumors. Many authors advocate the testicular sparing surgery in the treatment but epidermoid cysts are usually treated with radical inguinal orchiectomy, because of the difficulties in the diagnosis, concurrence of the malignant tumors, and the debate on the histogenesis.

Abstract
A 7-month-old male domestic ferret (Mustela putorius furo) was presented for evaluation of unilateral testicular enlargement. Microscopic examination of the left testicle revealed a neoplasm with differentiation along multiple cell lines (ectoderm, endoderm, mesoderm) including respiratory epithelium, bone and haired skin. A poorly differentiated epithelial component was dispersed throughout the neoplasm with invasion of testicular lymphatics. The animal developed progressive dysuria and was euthanized. At necropsy, metastasis of the poorly differentiated epithelial component was present in the urinary bladder, ureters, prostate gland, pelvic fat, abdominal and thoracic lymph nodes, kidney and lung. This is the first report of a malignant testicular teratoma with widespread metastasis in this species.

Abstract
BACKGROUND The hypothalamic-pituitary-gonadal (HPG) and hypothalamic-pituitary-somatotropic (HPS) axes are strongly interconnected. Interactions between these axes are complex and poorly understood. These interactions are characterized by redundancies in reciprocal influences at each level of regulation and the combination of endocrine and paracrine effects that change during development. OBJECTIVES To comprehensively review the crosstalk between the HPG and HPS axes and related pathological and clinical aspects during various life stages of male subjects. MATERIALS AND METHODS A thorough search of publications available in PubMed was performed using proper keywords. RESULTS Molecular studies confirmed the expressions of growth hormone (GH) and insulin-like growth factor-I (IGF-I) receptors on the HPG axis and reproductive organs, indicating a possible interaction between HPS and HPG axes at various levels. Insulin growth factors participate in sexual differentiation during fetal development, indicating that normal HPS axis activity is required for proper testicular development. IGF-I contributes to correct testicular position during minipuberty, determines linear growth during childhood, and promotes puberty onset and pace through gonadotropin-releasing hormone activation. IGF-I levels are high during transition age, even when linear growth is almost complete, suggesting its role in reproductive tract maturation. Patients with GH deficiency (GHD) and insensitivity (GHI) exhibit delayed puberty and impaired genital development; replacement therapy in such patients induces proper pubertal development. In adults, few studies have suggested that lower IGF-I levels are associated with impaired sperm parameters. DISCUSSION AND CONCLUSION The role of GH-IGF-I in testicular development remains largely unexplored. However, it is important to evaluate gonadic development in children with GHD. Additionally, HPS axis function should be evaluated in children with urogenital malformation or gonadal development alterations. Correct diagnosis and prompt therapeutic intervention are needed for healthy puberty, attainment of complete gonadal development during transition age, and fertility potential in adulthood.

Abstract
The continuous presence of active male small ruminants prevents seasonal anestrus in females, but evidence of the same mechanism operating from the females to the males is scarce. This study assessed the effects of the continuous presence of ewes in estrus in spring on ram sexual activity, testicular size and echogenicity, and LH and testosterone concentrations. On 1 March, 20 rams were assigned to two groups (n = 10 each): isolated (ISO) from other sheep, or stimulated (STI) by 12 ewes, which were separated from the rams by an openwork metal barrier, allowing contact between sexes. Each week, four ewes were induced into estrus by intravaginal sponges. Live weight, scrotal circumference, testicular width (TW) and length (TL) were recorded at the beginning and at the end of the experiment, and testicular volume (TV) was calculated; at the same time, testicular ultrasonography and color Doppler scanning were performed. Blood samples (March to May) were collected once per week for testosterone determinations, and at the end of the experiment, blood samples were collected for 6 h at 20-min intervals for LH analysis. Rams were exposed to four estrous ewes in a serving-capacity test. Scrotal circumference, TW and TL were higher in the STI than in the ISO rams (P < 0.05) in May, and TV was higher (P < 0.05) in the STI (391 ± 17 cm3) than in the ISO rams (354 ± 24 cm3). In ISO rams, the number of white pixels was higher (P < 0.01) in May (348 ± 74) than in March (94 ± 21) and differed significantly (P < 0.01) from that of the STI rams in May (160 ± 33). In ISO rams, the number of grey pixels was higher (P < 0.05) in May (107 ± 3) than it was in March (99 ± 1). Stimulated and ISO rams did not differ significantly in mean LH plasma concentrations (0.8 ± 0.5 v. 0.9 ± 0.4 ng/ml), LH pulses (2.1 ± 0.5 v. 2.2 ± 0.2) and amplitude (2.0 ± 0.4 v. 3.2 ± 0.7 ng/ml, respectively). Stimulated rams had significantly higher testosterone concentrations than ISO rams from April to the end of the experiment. Stimulated rams performed more (P < 0.05) mountings with intromission (3.0 ± 0.4) than did ISO rams (1.5 ± 0.5). In conclusion, after 3 months in the continuous presence of ewes in estrus in spring, rams had higher TV and some testicular echogenic parameters were modified than isolated rams. Although exposed rams also had higher levels of testosterone after 2 months in the presence of estrous ewes, their LH pulsatility at the end of the study was not modified.

Abstract
Testicular torsion is a serious urological disease leading to testicular damage. This study aimed to assess the effect of minocycline on testicular ischaemia/reperfusion (I/R) injury caused by testicular torsion/detorsion. Male adult Wistar rats (n = 32) were assigned into four groups of sham, I/R, I/R + minocycline and minocycline. I/R injury was induced by two sets of surgical operations, including the rotation of the left testis (720°, counterclockwise), followed by detorsion after 4 hr. The administration of minocycline was carried out 30 min before detorsion and then continued for 8 weeks. At the end of the 8th week, rats were killed and sampling was done. Johnson's score, the height of seminiferous tubule epithelium, the mean seminiferous tubule diameter, as well as biochemical parameters, SOD, GPx and CAT, were significantly enhanced in the I/R + minocycline group compared with the I/R group. The administration of minocycline led to a marked decrease in expression levels of Caspase-3, Bax, IL-1β and TNF-α genes, and a remarkable increase in expression levels of Bcl-2, 3β-HSD and 17β-HSD3 genes compared with the I/R group. Administration of minocycline could also reduce the rate of germ cell apoptosis (TUNEL staining). Hence, minocycline was useful in the management of testicular torsion/detorsion.

Abstract
Objectives The objective of this review was to characterize the use of biomarkers of male hypogonadism in childhood and adolescence. Contents The hypothalamic-pituitary-gonadal (HPG) axis is active during fetal life and over the first months of postnatal life. The pituitary gland secretes follicle stimulating hormone (FSH) and luteinizing hormone (LH), whereas the testes induce Leydig cells to produce testosterone and insulin-like factor 3 (INSL), and drive Sertoli cells to secrete anti-Müllerian hormone (AMH) and inhibin B. During childhood, serum levels of gonadotropins, testosterone and insulin-like 3 (INSL3) decline to undetectable levels, whereas levels of AMH and inhibin B remain high. During puberty, the production of gonadotropins, testosterone, and INSL3 is reactivated, inhibin B increases, and AMH decreases as a sign of Sertoli cell maturation. Summary and outlook Based on our knowledge of the developmental physiology of the HPG axis, these biomarkers can be used in clinical practice to interpret the physiopathology of hypogonadism. Additionally, these markers can have diagnostic value in different forms of hypogonadism that may appear during childhood and adolescence.

Abstract
OBJECTIVES This study aims to demonstrate the effect of subcutaneous injections of abatacept on the histology of testes in mice. MATERIALS AND METHODS The study included 20 male BALB/c mice (average weight, 25 g; aged 12-14 weeks). Ten mice received subcutaneous (SC) injections of abatacept [0.25 mg per 25 g body weight per 0.03 mL normal saline (NS)] at zero, two, four and eight weeks. As the control group, 10 mice received SC injections of NS (0.03 mL). At the post-injection 10th week, the mice were sacrificed, and histopathological studies were conducted. RESULTS The results showed that 3/10 mice died of the abatacept-treated group. Testicular histology for the abatacept-treated group showed that 7/7 displayed no histopathological changes. CONCLUSION To our knowledge, this is the first control-blinded study of BALB/c mice suggesting that abatacept may not have testicular toxicity. Further fertility and testicular toxicology evaluations including semen analysis and gonadal hormones should be performed to clarify our findings.

Abstract
High-fat diets affect male reproduction and sexual function. Therefore, we evaluated the effects of prolonged resveratrol administration on the metabolic, sperm, and testicular parameters of rats fed a cafeteria diet. Male Wistar rats were divided at weaning into control (C, n = 20) and cafeteria (CAF, n = 16) groups. At 3 months, half of them were given daily supplementations of resveratrol (C-R, n = 10; CAF-R, n = 8) at a dosage of 30 mg kg-1 body mass for 2 months. Animals were killed at 5 months of age, and blood, spermatozoa, and testes were collected for further analysis. Data were analyzed by one-way ANOVA, and P < 0.05 was considered statistically significant. The CAF diet promoted hyperglycemia (P < 0.0001), and treatment with resveratrol reversed this condition (P < 0.0001). The CAF diet reduced sperm viability and motility, while resveratrol improved these parameters (P < 0.05). Regarding testicular morphology, the height of the seminiferous epithelium was reduced in the CAF group compared with that of the C group (P = 0.0007). Spermatogenic cell proliferation was also reduced in the CAF group compared with that of the C group. However, the CAF-R showed an increase in cell proliferation rate compared with that of the untreated CAF group (P = 0.0024). Although it did not modify body mass, the consumption of a CAF diet promoted hyperglycemia, adverse testicular morphology remodeling, and abnormal sperm, which were attenuated by treatment with resveratrol, thus suggesting a protective effect of this antioxidant on spermatogenesis.

Abstract
Although stem cell therapy is a promising alternative for treatment of degenerative diseases, there are just few reports on the use of stem cells therapy in horse's reproductive system. This study aims to evaluate the effect of intratesticular injection of bone marrow mesenchymal stromal/stem cells (MSCs) in healthy stallions, and its outcome on seminal parameters and fertility. In Experiment 1, 24 stallions were divided into treatment group (TG) and control group (CG). In the TG, an intratesticular application of MSC was performed, and in the CG, only PBS was used. Measurements of testicular volume, surface temperature and Doppler ultrasonography were performed 24 and 48 hr after treatments. Fifteen days after application, the testicles were removed and submitted to histological analysis. In Experiment 2, 3 fertile stallions received similarly treatment with MSCs. Physical examination and sperm analysis were performed weekly during 60 days after treatment, and at the end, semen from one of them was used for artificial inseminations of 6 healthy mares. In Experiment 1, clinical examinations showed no signals of acute inflammation on both groups according to the analysed variables (p > .05). Also, no signal of chronic inflammation was observed on histological evaluation. In Experiment 2, stallions presented no physical alterations or changes in sperm parameters, and a satisfactory fertility rate (83%; 5/6) was observed after AI. The results support the hypothesis that intratesticular application of bone marrow MSCs is a safe procedure, and this could be a promising alternative to treat testicular degenerative conditions.

Abstract
We investigated the effects of ethyl pyruvate (EP) on oxidative and endoplasmic reticulum (ER) stress due to experimental testicular ischemia-reperfusion (I-R). Eighteen rats were divided into a control group, a torsion-detorsion (T-D) group and an EP group. For pretreatment of the EP group, 50 mg/kg EP was given intraperitoneally (i.p.) 30 min before detorsion. Tissue 4-hydroxynonenal (4-HNE) and 78-kDa glucose-regulated protein (GRP78) levels were determined using enzyme-linked immunosorbent assay (ELISA) kits. Tissue total oxidant status (TOS) and total antioxidant status were determined using colorimetric methods. Histology of the tissues was evaluated using hematoxylin and eosin staining. In the T-D group, tissue 4-HNE, GRP78, TOS and oxidative stress index levels were significantly higher than for the control group. The increases were reduced significantly by EP pretreatment. Our findings suggest that EP can inhibit I-R induced testicular injury by suppressing oxidative and ER stress. EP may be a useful adjunctive treatment for surgical repair in humans.

Abstract
BACKGROUND Considered the most common congenital testicular abnormality of companion animals and a predisposition factor to the development of testicular neoplasia, cryptorchidism is defined as the non-descent of one or both testes to their normal anatomical location. Data on the occurrence of cryptorchidism in Brazil are scarce. The purpose of this work was to verify the occurrence of cryptorchidism in dogs of different sizes and breeds. MATERIALS AND METHODS Cryptorchidism identification was carried out by ultrasound scanning, from November, 1994 to March, 2007, at the Centre for Veterinarian Diagnosis and Support (Centro de Apoio e Diagnóstico Veterinário - CAD), in Rio de Janeiro. 4924 male dogs of different breeds were examined, revealing 403 (8.2%) cryptorchidism. RESULTS In this study, occurrence took place more often on the right testicle (59.5%), more frequently displaying inguinal localisation (59.5%) and unilateral occurrence (70%). Regarding bilateral presentation, the symmetrical form was the most common (86.8%). Cryptorchidism was more common in the inguinal region of dog of small sized breeds and in the abdominal region in dogs of medium- and large-sized breeds. CONCLUSIONS Ultrasound scan proved a valuable diagnosis tool for cryptorchid testes, giving precise localisation and parenchymal changes thus leading to a safe clinical treatment.

Abstract
Hibernation has been proposed as a tool for human space travel. In recent years, a procedure to induce a metabolic state known as “synthetic torpor” in non-hibernating mammals was successfully developed. Synthetic torpor may not only be an efficient method to spare resources and reduce psychological problems in long-term exploratory-class missions, but may also represent a countermeasure against cosmic rays. Here we show the preliminary results from an experiment in rats exposed to ionizing radiation in normothermic conditions or synthetic torpor. Animals were irradiated with 3 Gy X-rays and organs were collected 4 h after exposure. Histological analysis of liver and testicle showed a reduced toxicity in animals irradiated in torpor compared to controls irradiated at normal temperature and metabolic activity. The expression of ataxia telangiectasia mutated (ATM) in the liver was significantly downregulated in the group of animal in synthetic torpor. In the testicle, more genes involved in the DNA damage signaling were downregulated during synthetic torpor. These data show for the first time that synthetic torpor is a radioprotector in non-hibernators, similarly to natural torpor in hibernating animals. Synthetic torpor can be an effective strategy to protect humans during long term space exploration of the solar system.

Abstract
Spontaneous regression of a primary testicular germ-cell tumour (GCT), over time known as 'Burned out', 'Shrinking Seminoma', 'pT0', 'Burnout' or 'Spontaneous Regression', is an uncommon, generally metastatic phenomenon, which may present elevated tumour markers and a suspicious testicular ultrasound image. The histological study of the testicle demonstrated morphological changes of complete or partial tumour regression and found fibrous scarring and other characteristic changes of this phenomenon, which in some cases include vestiges of GCT. There are few publications on testicular GCT tumour regression and those that exist present limited data on the biology of the disease and its etiopathogenesis. This entity was recently recognised in the latest edition of the World Health Organization's (WHO) Classification of Tumours. We present our clinical, imaging, laboratory, cytohistological and management experience, as well as a historical review of the literature.

Abstract
About 4% of male patients with cancer are under the age of 35 years. With the current increase in efficacy and safety of therapies, a growing number of young adults can achieve long-term survival. In male patients receiving systemic chemotherapy and or bone marrow transplantation, a permanent loss of fertility is a common adverse effect. The only possibility to preserve the patient’s fertility is to spare the gametes or gamete-forming cells from the chemotherapeutic effect. In adults, this can be achieved by the cryopreservation of spermatozoa with the subsequent application of assisted reproductive technology. Sperm cryopreservation is currently performed using slow-rate cryopreservation as a standard method, in which sperm cells are incubated with a cryoprotective medium and slowly subjected to hypothermia in liquid nitrogen (LN) vapor before they are placed in LN. Another technique called vitrification relies on the direct placement of the cells into LN, after being suspended in a vitrification medium. Many studies compared the clinical outcomes of both techniques and revealed equivalent results. This paper sheds light on some innovative approaches for further progress.

Abstract
OBJECTIVE This study aimed to compare a new vitrification protocol with reduced cryoprotectant exposure to the slow freezing method in the cryopreservation of prepubertal rat testicular tissue. METHODS Five sexually immature male Wistar rats were submitted to bilateral orchiectomy. Tissue samples from each testicle were fragmented into small pieces and randomly assigned to three groups: Group A, fresh tissue (control); Group B, slow programmable freezing (SPF); and Group C (vitrification). Frozen/thawed, vitrified/warmed, and fresh testicular tissue were histologically compared. A pathologist blinded to the procedures assessed the morphology (cell differentiation, nuclei, and epithelium) of 10 seminiferous tubules from each testicle (100 tubules per Group). RESULTS Sertoli and spermatogonial stem cells were easily differentiated, and the nucleoli were easily viewed in the tubules assessed in all three groups. Small alterations in tissue architecture were observed in the control group as a result of tissue handling. Moderate alterations of the epithelium with the formation of small gaps and cell detachment from the basement membrane were observed in 28% of the frozen and 9% of the vitrified tubules. Condensed nuclei involving a small proportion of cells were observed in six and three tubules of the frozen and vitrified group, respectively. Despite the alterations, 97% of the frozen and 99% of the vitrified tubules were considered well preserved. CONCLUSIONS The findings indicate that the vitrification protocol tested in this study adequately preserved the morphological integrity of prepubertal testicular tissue in a rat model. Further studies are required to confirm testicular tissue function after grafting.
