Although histoplasmosis is generally a self-limited disease, disseminated infection can occur in patients lacking effective cell-mediated immunity, reaching virtually every organ, even the genitourinary tract in rare cases. We report a case of epididymo-orchitis in an immunocompetent 38-year-old bricklayer from the rural area of Villeta, Cundinamarca, Colombia. The patient presented with testicular pain and macroscopic scrotal changes requiring a left orchiectomy, with microbiological isolation and molecular confirmation of Histoplasma capsulatum...

This study aimed to investigate the role of microRNA (miRNA) in heat stress-induced spermatogenic impairment. Testes from 15 adult ICR mice subjected to testicular hyperthermia at 43°C for 30 min and from 15 control mice were collected and pooled into 3 samples. Isolated RNA from these samples was subjected to small RNA high-throughput sequencing, and differentially expressed miRNAs were identified and validated using RT-PCR. The identified miRNAs were further subjected to Gene Ontology and KEGG analyses, which revealed significant enrichment for pathways potentially involved in heat stress-induced spermatogenic impairment...

Synergism between extrinsic and intrinsic factors is crucial for the seasonality of reproduction. Environmental factors such as photoperiod and temperature activate the hypothalamus-pituitary-gonadal axis leading to the secretion of steroid hormones that are crucial for reproduction. Sex steroids are not only essential for the maturation of gonads, but also for development of secondary sexual characters in males and reproductive behaviour of both the sexes. In the present study, we quantified the urinary testosterone (UTM) and corticosterone (UCM) metabolites in males and urinary estradiol metabolites (UEM) and UCM in females of Nyctibatrachus humayuni for two consecutive years to determine annual and seasonal variation in the levels of sex steroids, corticosterone and body condition index (BCI)...

Increasing lines of evidence suggest that miRNAs are closely related to spermatogenesis and male infertility which has aroused widespread concerns.The miR-379/miR-544 locus is the largest known placental mammal-specific miRNA cluster, whose 24 miRNA genes are expressed only from the maternal allele, and located within the high conservation of the imprinted Dlk1â€"Dio3 region.A correct dosage of imprinted genes encoded at the mouse Dlk1-Dio3 genomic interval is essential for embryonic growth and postnatal survival, as well as for muscle growth, skeletal, and neuronal development...

This study aims to evaluate the predictive value of left testicular volume (LTV) and right testicular volume (RTV) for testicular function respectively. Men who requested fertility testing for any reason were enrolled from December 2012 to November 2015. Subjects with primary scrotal diseases or a condition interfering reproductive system were excluded. Testicular volume (TV) was evaluated by scrotal ultrasound. Sex hormone and semen analysis including sperm concentration (SC) and sperm motility rate (SMR) were performed...

Telomeres are repeating DNA found at the ends of chromosomes that, in the absence of restorative processes, shorten with cell replications and are implicated as a cause of senescence. It appears that sperm telomere length (TL) increases with age in humans, and as a result offspring of older fathers inherit longer telomeres. We review possible mechanisms underlying this paternal age at conception (PAC) effect on TL, including sperm telomere extension due to telomerase activity, age-dependent changes in the spermatogonial stem cell population (possibly driven by 'selfish' spermatogonia) and non-causal confounding...

BACKGROUND/AIMS: Malignant mesothelioma of the tunica vaginalis testis is a rare and lethal disease. The genomic characteristics and genetic changes of tumor cells during the progression of this disease are unknown. METHODS: we performed whole-genome sequencing of four successive tumor samples derived from surgery and a blood sample in a single patient. RESULTS: All tumors were found to have significant C-to-T and T-to-C mutations, and amplification of copy number in chromosomes 1 and 12 were notified in all tumor samples...

The tumor suppressor p53, and the cyclin-dependent kinase inhibitor Ink4c, have been both implicated in spermatogenesis control. Both p53-/- and Ink4c-/- single knockout male mice are fertile, despite testicular hypertrophy, Leydig cell differentiation defect, and increased sperm count in Ink4c-/- males. To investigate their collaborative roles, we studied p53-/- Ink4c-/- dual knockout animals, and found that male p53-/- Ink4c-/- mice have profoundly reduced fertility. Dual knockout male mice show a marked decrease in sperm count, abnormal sperm morphology and motility, prolongation of spermatozoa proliferation and delay of meiosis entry, and accumulation of DNA damage...

Testicular cancer represents approximately 1% of all cancers diagnosed in males. The prevalence of bilateral testicular germ cell tumor cases varies from 1% to 5%. Intratubular germ cell neoplasia (ITGCN) is a precursor for almost all testicular germ cell tumors (TGCT) and is one of the highest risks of developing contralateral testicular cancer. The radical orchiectomy is still preferred for the treatment of testicular cancer. However, in some cases like solitary testis, bilateral cancer or if the tumor size is under 30% percent of the testicular extent, organ-sparing surgery can be an option...

Straw colored pleural fluid with raised adenosine deaminase (ADA) levels in young healthy adults usually raises suspicion of tuberculosis, sometimes leading to laxity in carrying thorough physical examination and missing out some important clues with potential disastrous consequences. A 35-year-old male was diagnosed to have left pleural effusion and anti-tubercular treatment was started on the basis of straw colored, lymphocyte-predominant pleural fluid with significantly raised ADA levels. When there was no improvement after 1 month of treatment he was investigated further and found to have a mediastinal mass along with hydro-pneumothorax...

INTRODUCTION: The role of autoimmune responses against central nervous system (CNS) antigens in encephalitis presenting with non-classified neurologic or psychiatric symptoms has been appreciated in the past decade. Paraneoplastic limbic encephalitis has a poor prognosis and is most commonly associated with lung, ovarium, and testicular neoplasms, leading to immune reactions against intracellular antigens (anti-Hu/ANNA1, anti-Ri/ANNA2, anti-CV2/CRMP5 and anti-Ma2/Ta). In contrast, the recently described autoimmune encephalitis subtypes present with a broad spectrum of symptoms, respond to autoimmune therapies well and usually associate with autoantibodies against neuronal cell surface receptors (NMDAR, GABABR, AMPAR) or synaptic proteins (LGI1, CASPR2)...

Mitotane (o,p'DDD) is established in the adjuvant and advanced stage treatment of adrenocortical carcinoma and counteracts both tumour growth and tumour-related steroid production. Both the adrenal glands and the gonads are steroidogenically active organs and share a common embryogenic origin. Here we describe the effects of mitotane in two patients with metastatic Leydig cell tumour (LCT) of the testes and associated severe androgen excess (serum testosterone 93 and 88 nmol/l, respectively; male reference range 7-27 nmol/L)...
