Nutritional perturbation during gestation alters male reproductive development in rodents and sheep. In cattle both the developmental trajectory of the feto-placental unit and its response to dietary perturbations is dissimilar to that of these species. This study examined the effects of dietary protein perturbation during the peri-conception and first trimester periods upon reproductive development in bulls. Nulliparous heifers (n=360) were individually fed a high- or low-protein diet (HPeri and LPeri) from 60 days before conception...

The present study investigated whether grape seed proanthocyanidin extract (GSPE) can attenuate varicocele‑induced testicular oxidative injury through the nuclear factor (erythroid‑derived 2)‑like 2 (Nrf2) antioxidant pathway. A varicocele model in rats was established by partial ligation of the left renal vein. Following 4 weeks of GSPE administration, the decreased sperm count and motility and other pathological changes caused by varicocele were significantly alleviated, as indicated by the results of computer‑assisted sperm analysis and hematoxylin and eosin staining...

MAGE-A9, a well-characterized cancer testis antigen (CTA), belongs to a member of melanoma antigen gene (MAGE) family. In human malignancies, aberrant expression of MAGE genes correlated with poor clinical prognosis, increased tumor growth, metastases, and enrichment in stem cell populations of certain cancers. Cancer stem cells (CSCs) have been proposed to contribute to the major malignant phenotypes of liver cancer, including recurrence, metastasis and chemoresistance. However, expression and potential role of MAGE-A9 in liver cancer stem cells (LCSCs) still remain unclear...

Reka K Kelemen, Beatriz Vicoso
The t-haplotype, a mouse meiotic driver found on chromosome 17, has been a model for autosomal segregation distortion for close to a century, but several questions remain regarding its biology and evolutionary history. A recently published set of population genomics resources for wild mice includes several individuals heterozygous for the t-haplotype, which we use to characterize this selfish element at the genomic and transcriptomic level. Our results show that large sections of the t-haplotype have been replaced by standard homologous sequences, possibly due to occasional events of recombination, and that this complicates the inference of its history...

We present a video of our technique for resection of a large prostatic utricle (PU) in a patient who presented initially with disordered sexual development. His karyotype was 46XY, and phenotypically had penoscrotal hypospadias, bifid scrotum, and retractile right testis. An initial micturating cystourethrogram (MCUG) demonstrated the utricle but failed to cannulate the bladder. Being asymptomatic, we carried out staged repair of his hypospadias. Later, he started to have recurrent epididymo-orchitis with resistance to multiple antibiotics...

Di-N-butylphthalate (DBP) is one of the most common endocrine-disrupting chemicals which can disrupt human endocrine system, especially in the male reproductive system. Here, this study was aimed to determine whether sulforaphane (SFN) could protect against testicular oxidative stress injury induced by DBP in male mice offsprings. Wild-type (Nrf2(+/+)) and Nrf2-deficient (Nrf2(-/-)) timed-pregnant mice were given DBP orally from embryonic day (E)14.5 to E19.5. Subsequently, the oxidative stress markers were evaluated...

The testis has been described in animal models as a site of immune privilege, which protects spermatids against tissue damage during inflammation. Myeloid cells, including macrophages and dendritic cells (DC), are defined as key players in the testicular immune privilege in animal models. However, their distribution and frequency in human testis remain poorly described. To overcome the challenges related to tissue sampling, we obtained testicular tissue from men under hormonal therapy who elected to have sex reassignment surgery (SRS)...

BACKGROUND: Hyperglycemia can result from a loss of pancreatic beta-cells or a decline in their function leading to decreased insulin secretion or may arise from insulin resistance and variable degrees of inadequate insulin secretion resulting in diabetes and related comorbidities. To date several reviews have addressed the issue of diabetes-related male infertility but most have focused on how metabolic syndrome causes the decline in male fertility. However, a comprehensive overview as to how diabetes-induced hyperglycemia impairs male fertility is missing...

Male genital diversification is likely the result of sexual selection. Female genital diversification may also result from sexual selection, although it is less well studied and understood. Female genitalia are complex among whales, dolphins, and porpoises, especially compared to other vertebrates. The evolutionary factors affecting the diversity of vaginal complexity could include ontogeny, allometry, phylogeny, sexual selection, and natural selection. We quantified shape variation in female genitalia using 2-D geometric morphometric analysis, and validated the application of this method to study soft tissues...

In males with nonobstructive azoospermia, one of the main histopathologic patterns of the testis is Sertoli cell-only syndrome (SCOS), in which no germ cells are present and only Sertoli cells are contained in the seminiferous tubules. There is not any formal treatment for this pathological condition. However, several studies reported the possibility to perform testicular sperm extraction in patients with SCOS, although, according to some authors, sperm retrieval is possible only in the presence of focal spermatogenesis...

PURPOSE: To discuss an optimal surgical approach for impalpable testis in children, our own treatment results and those reported in the literature were reviewed. MATERIALS AND METHODS: Seventy-two impalpable testes were diagnosed in 68 patients: unilateral in 64 patients and bilateral in 4 patients. All patients underwent surgical exploration at the ages of 6 to 140months (median, 15months). The inguinal canal was initially explored, and abdominal exploration was performed with laparoscopy when an extra-abdominal testis was not identified...

P-Element induced wimpy testis (PIWI)-interacting RNAs (piRNAs) are a type of noncoding RNAs (ncRNAs) and interact with PIWI proteins. piRNAs were primarily described in the germline, but emerging evidence revealed that piRNAs are expressed in a tissue-specific manner among multiple human somatic tissue types as well and play important roles in transposon silencing, epigenetic regulation, gene and protein regulation, genome rearrangement, spermatogenesis and germ stem-cell maintenance. PIWI proteins were first discovered in Drosophila and they play roles in spermatogenesis, germline stem-cell maintenance, self-renewal, retrotransposons silencing and the male germline mobility control...

Extracellular matrix (ECM) plays an important scaffolding role in the establishment of organs structure during development. A great number of ECM components and enzymes (proteinases) regulating formation/degradation of ECM during organ remodeling have been identified. In order to study the role of ECM in the mouse gonad development, especially during sexual differentiation of the gonads when the structure of the testis and ovary becomes established, we performed a global analysis of transcriptome in three main cell types of developing gonad (supporting, interstitial/stromal and germ cells) using transgenic mice, cell sorting and microarray...

Accurate diagnosis of primary and metastatic tumours is essential in testicular cancer. While many cases are straightforward, some pose difficulties, especially when variant morphologies occur. Seminoma with 'atypical' features, including increased nuclear pleomorphism and crowding and greater cytoplasmic density with loss of membrane definition, mimics embryonal carcinoma, although ancillary features (fibrous septa, lymphocytes) and immunohistochemistry are of great help. Other deceptive seminoma features include prominent to exclusive intertubular growth, microcystic/tubular patterns, and signet-ring tumour cells...

Recent studies highlighted that apolipoprotein D (ApoD) and its homologs exert neuroprotective and antioxidant functions in mammals and Drosophila. Unlike mammals and Drosophila, lepidopteran insects possess three distinct ApoD homologs. However, few information on their functions in lepidopteran insects are available. In this study, we investigated the protective potential of a novel ApoD homolog, BmApoD1, in Bombyx mori. Quantitative PCR analyses demonstrated that BmApoD1 is extensively expressed at low levels during the larval stage but abundantly expressed in the testis during the pupal and adult stages...

Allogeneic hematopoietic stem cell transplantation (HSCT) can cure single gene disorders such as thalassemia and sickle cell anemia (SCA). These non-malignant diseases have in common severe hemolytic anemia and high proliferative bone marrow, requiring frequent transfusions. The risk of rejection is high and graft-vs-host disease is not desirable. Important progress has been made in the management of these diseases, including leukocyte depletion of blood products, and chelation therapy, for both diseases, and erythrocytapheresis and hydroxycarbamide for SCA...
