Congenital bilateral absence of the vas deferens (CBAVD) is found in 1% to 2% of males with infertility and is present in 6% of obstructive azoospermia cases. Nearly 95% of men with cystic fibrosis (CF, an autosomal recessive disorder) have CBAVD. There are genetic links between CBAVD and CF. Some mutations in the gene encoding cystic fibrosis transmembrane conductance regulator (CFTR) can lead to CBAVD as a monosymptomatic form of CF. With the use of assisted reproductive techniques (ART), especially testicular or epididymal sperm aspiration, intracytoplasmic sperm injection, and in vitro fertilization, it is possible that men with CBAVD can produce offspring...

The present study evaluates the protective effect of α-lipoic acid (LA) against arsenic-induced testicular and epididymal oxidative damage in rats. Arsenic caused significant reduction in the reproductive organ weights, serum testosterone levels, testicular daily sperm count, epididymal sperm count, sperm motility, sperm viability, and sperm membrane integrity. Significant reduction in the activity levels of superoxide dismutase, catalase, and glutathione levels with a concomitant increase in the lipid peroxidation and protein carbonyl content in the testis and the cauda epididymis of arsenic-exposed rats...

Functional genome analysis usually is performed on the level of genotype-phenotype interaction. However, phenotypes also depend on the relations between genomes and environment. In our experimental system, we observed differential response to environmental factors defined by different conditions of husbandry in a semi-barrier unit or in a SPF (specific pathogen free) barrier unit, which resulted in partial reversal of phenotypes previously observed under semi-barrier conditions. To provide an update of basic phenotypes in unselected and randomly mated controls (DUC) and long-term selected DUhTP (Dummerstorf high treadmill performance) mice in the SPF facility, we compared growth parameters, reproductive performance, the accretion of muscle and fat mass, physical activity, and running performance as well as food intake in all experimental groups...

A 60-year-old man presented with unilateral testicular pain and urinary frequency. His presenting prostate-specific antigen (PSA) was 100 ng/mL, and a biopsy revealed Gleason 4+4 prostate adenocarcinoma. The significance of his initial PSA was somewhat complicated by possible prostatitis and early initiation of bicalutamide. PSA rose on two occasions prior to radiotherapy but coincided with a flare of testicular pain on one of these. Whole-body staging diffusion-weighted MRI scan was negative. He was treated with 3 years of androgen deprivation therapy (ADT) and radical radiotherapy...

Adipose tissue is considered to be an endocrine organ, and adipocyte size correlates with insulin resistance and metabolic parameters in obesity. There is little data on the effects of angiopoietin-1 in adipose tissue and kidney in streptozotocin (STZ)-induced diabetes. In this study, we investigated the protective effect of COMP-angiopoietin-1 (COMP-Ang1), a potent variant of angiopoietin-1, on vascular endothelial cells in epididymal adipose tissue and its regulatory effect on other metabolic parameters, such as lipid droplet diameter, macrophage infiltration, and renal inflammation in STZ-treated mice...

Cystic lymphangiomas are usually congenital malformations of draining lymphatic channels with most common sites including neck, axilla, mediastinum and retroperitoneum. Occurrence of lymphangiomas in scrotum or inguinal region is a rare entity and epididymal origin of these lesions is even more infrequent. We herein report a case of epididymal lymphangioma detected on USG, which developed after surgical abdominal lymph nodal dissection in an adult patient of carcinoma rectum presenting as painless scrotal swelling...

Carcinoma prostate secondary metastasis to testicle and epididymis is rare. We report a case of metastatic carcinoma prostate in which testicular and epididymal metastasis were diagnosed incidentally in bilateral orchiectomy specimen. Testicular and para testicular structure should be properly evaluated for accurate staging of carcinoma prostate. Epididymis should always be included in bilateral orchidectomy specimen.

The present study investigated the anti‑obesity effects of enzyme‑treated Ecklonia cava extract (EEc) in C57BL/6N mice with high‑fat diet (HFD)‑induced obesity. The EEc was separated and purified with the digestive enzymes pectinase (Rapidase X‑Press L) and cellulase (Rohament CL) and its effects on the progression of HFD‑induced obesity were examined over 10 weeks. The mice were divided into 6 groups (n=10/group) as follows: Normal diet group, HFD group, mice fed a HFD with 25 mg/kg/day Garcinia cambogia extract and mice fed a HFD with 5, 25 or 150 mg/kg/day EEc (EHD groups)...

Jennifer R Hughes, Trish Berger
Apical blebbing, a non-classical secretion mechanism, occurs in the mature porcine epididymis as part of its normal function. Proteins secreted by this mechanism contribute to the modification of the sperm plasma membrane during epididymal transit and are thought to contribute to acquisition of fertilizing ability. However, little is known about the regulation of this secretion mechanism in an in vivo model. Previous work demonstrated apical blebbing in the epididymis developed pubertally, suggesting androgens, sperm or other luminal factors regulated this process...

Uncoupling protein-1 (UCP1) facilitates thermogenesis in brown and beige adipocytes and can promote energy expenditure by decreasing mitochondrial respiratory efficiency. Defects in UCP1 and brown adipose tissue thermogenesis subject animals to chronic cold stress and elicit compensatory responses to generate heat. How UCP1 regulates white adipose tissue (WAT) lipid biology and tissue crosstalk is not completely understood. Here, we probe the effect of UCP1 deficiency on fatty acid metabolism in inguinal and epididymal WAT and investigate how these metabolic perturbations influence hepatic lipid homeostasis...

Human semen quality is declining in many parts of the world, but the causes are ill-defined. In rodents, impaired sperm production can be seen with early life exposure to certain endocrine disrupting chemicals, but the effects of combined exposures are not properly investigated. In this study, we examined the effects of early exposure to the painkiller paracetamol and mixtures of human relevant endocrine disrupting chemicals in rats. One mixture contained four estrogenic compounds, another contained eight anti-androgenic environmental chemicals, and a third mixture contained estrogens, anti-androgens and paracetamol...

Non-Alcoholic SteatoHepatitis (NASH) is the more severe form of Non-Alcoholic Fatty Liver Disease (NAFLD) and is characterized by the presence of hepatic steatosis, oxidative stress, inflammation, hepatocyte injury with or without fibrosis. Recently, GPR119 receptor has emerged as a novel therapeutic target for the treatment of dyslipidemia and non-alcoholic steatohepatitis. In the present study, we investigated the effect of APD668, a GPR119 agonist alone or in combination with linagliptin, a DPPIV inhibitor on the progression of steatohepatitis in mice fed on a high trans-fat diet...

There are reports of sulfasalazine (Salazosulfapyridine; SASP)-induced reproductive toxicity, but there it is not known whether the SASP molecule or its intestinal metabolites are responsible for this effect. Rats received SASP (150, 300, and 600mg/kg) for 60 consecutive days (in vivo). Additionally, epididymal sperm was isolated and incubated with SASP (10μM-1600μM) (in vitro). Markers of oxidative stress, mitochondrial function, and sperm functionality, along with testis histopathology as well as several steroidogenic genes and proteins, including steroidogenic acute regulatory (StAR) protein, cytochrome P450 side chain cleavage enzyme (P450scc; Cyp11a), 3β-hydroxysteroid dehydrogenase (3β-HSD), 17β-hydroxysteroid dehydrogenase (17β-HSD) were measured...

Epididymal lumen fluids are directly responsible for sperm maturation. However, very little is known about the molecular details of small molecule metabolites in the epididymal lumen fluids until now. Here we identified and compared the metabolic profiles of mouse caput and cauda epididymal lumen fluids using GC-MS technique. Among 236 metabolites identified in caput and cauda epididymis, 36 were significantly enriched in caput epididymis while 18 were significantly enriched in cauda epididymis. Pathway analysis identified ascorbate and aldarate metabolism and beta-alanine metabolism as most relevant pathways in caput and cauda epididymis, respectively...
