"Bisphenol a: an emerging threat to male fertility".

Reprod Biol Endocrinol 2019 Jan 20;17(1). Epub 2019 Jan 20.

Dipartimento di Medicina Molecolare e Biotecnologie Mediche, Università degli Studi di Napoli Federico II, Via Sergio Pansini, 5 -, 80131, Naples, Italy.

Background: Among the factors causing male infertility, one of the most debated is the exposure to environmental contaminants. Recently, the chemical compound Bisphenol A (BPA) has drawn attention from the reproductive science community, due to its ubiquitous presence in day-to-day life. Its toxic action appears to mainly affect the male reproductive system, directly impacting male fertility. Read More

Proper direction of male genitalia is prerequisite for copulation in Drosophila, implying cooperative evolution between genitalia rotation and mating behavior.

Sci Rep 2019 Jan 18;9(1):210. Epub 2019 Jan 18.

Osaka University, Graduate School of Science, Department of Biological Sciences, Osaka, 560-0032, Japan.

Animal morphology and behavior often appear to evolve cooperatively. However, it is difficult to assess how strictly these two traits depend on each other. The genitalia morphologies and courtship behaviors in insects, which vary widely, may be a good model for addressing this issue. Read More

J Cell Physiol 2019 Jan 9. Epub 2019 Jan 9.

College of Animal Science, Jilin University, Changchun, China.

The brain-derived neurotrophic factor (BDNF) was first recognized for its roles in the peripheral and central nervous systems, and its complex functions on mammalian organs have been extended constantly. However, to date, little is known about its effects on the male reproductive system, including the steroidogenesis of mammals. The purpose of this study was to elucidate the effects of BDNF on testosterone generation of Leydig cells and the underlying mechanisms. Read More

Evolution of gene expression levels in the male reproductive organs of mosquitoes.

Life Sci Alliance 2019 Feb 2;2(1):e201800191. Epub 2019 Jan 2.

School of Veterinary Medicine and Science, Sutton Bonington Campus, University of Nottingham, Leicestershire, UK.

Modifications in gene expression determine many of the phenotypic differentiations between closely related species. This is particularly evident in reproductive tissues, where evolution of genes is more rapid, facilitating the appearance of distinct reproductive characteristics which may lead to species isolation and phenotypic variation. Large-scale, comparative analyses of transcript expression levels have been limited until recently by lack of inter-species data mining solutions. Read More

A -acting bidirectional transcription switch controls sexual dimorphism in the liverwort.

EMBO J 2019 Jan 4. Epub 2019 Jan 4.

Graduate School of Science and Technology, Nara Institute of Science and Technology, Ikoma, Nara, Japan

Plant life cycles alternate between haploid gametophytes and diploid sporophytes. While regulatory factors determining male and female sexual morphologies have been identified for sporophytic reproductive organs, such as stamens and pistils of angiosperms, those regulating sex-specific traits in the haploid gametophytes that produce male and female gametes and hence are central to plant sexual reproduction are poorly understood. Here, we identified a MYB-type transcription factor, MpFGMYB, as a key regulator of female sexual differentiation in the haploid-dominant dioicous liverwort, MpFGMYB is specifically expressed in females and its loss resulted in female-to-male sex conversion.

Two Korean girls with complete androgen insensitivity syndrome diagnosed in infancy.

Ann Pediatr Endocrinol Metab 2018 Dec 31;23(4):220-225. Epub 2018 Dec 31.

Department of Laboratory Medicine, Seoul National University Hospital, Seoul, Korea.

Androgen insensitivity syndrome (AIS) is a rare genetic disease caused by various abnormalities in the androgen receptor (AR). The AR is an essential steroid hormone receptor that plays a critical role in male sexual differentiation and development and preservation of the male phenotype. Mutations in the AR gene on the X chromosome cause malfunction of the AR so that a 46,XY karyotype male has some physical characteristics of a woman or a full female phenotype. Read More

The structure of the male terminalia and their musculature of species of tanyderid genera Alexander, 1929 from Chile and Alexander, 1927 from Tasmania are examined and compared with each other and with published data on the likely relatives. The overall pattern of male terminalia of both genera is similar to those of most Southern Hemisphere genera, with simple curved gonostyli, lobe-like setose parameres, and setose cerci inconspicuous under the epandrium. Both genera have terminalia similarly rotated by 180° (and 90° as an intermediate stage); rotation may be either clockwise or counterclockwise. Read More

Access to pasture in an outdoor housing system affects welfare indicators and improves rooster sperm quality in two native Mediterranean breeds.

Poult Sci 2018 Dec;97(12):4433-4441

INRA 0085 UMR PRC INRA-CNRS-University François Rabelais-Haras Nationaux, 37380 Nouzilly, France.

The aim of the present work was to examine the influence of access to pasture in an outdoor housing system on rooster sperm quality and response to cryopreservation and to examine the possible correlation between values for sperm quality variables and welfare indicators. Two groups of Black-barred Andaluza and Red-barred Vasca roosters were housed in an outdoor system, with one group given daily access to a grazing area containing plant species that typically grow on uncultivated Mediterranean land. Semen was collected once per week from each group, and the following sperm quality variables were assessed: sperm volume, appearance, concentration, motility, membrane integrity, acrosome integrity, and morphological abnormalities.

Identification of novel multi-stage histone deacetylase (HDAC) inhibitors that impair Schistosoma mansoni viability and egg production.

Parasit Vectors 2018 Dec 27;11(1):668. Epub 2018 Dec 27.

National Research Council, Institute of Cell Biology and Neurobiology, Campus A. Buzzati-Traverso, Monterotondo (Roma), Italy.

Background: Novel anti-schistosomal multi-stage drugs are needed because only a single drug, praziquantel, is available for the treatment of schistosomiasis and is poorly effective on larval and juvenile stages of the parasite. Schistosomes have a complex life-cycle and multiple developmental stages in the intermediate and definitive hosts. Acetylation and deacetylation of histones play pivotal roles in chromatin structure and in the regulation of transcription in eukaryotic cells. Read More

Steroid concentrations in maternal serum and uterine histotroph in round stingrays (Urobatis halleri).

Gen Comp Endocrinol 2018 Dec 18. Epub 2018 Dec 18.

Faculty of Veterinary Medicine, University of Calgary, AB, Canada.

Despite a wide range of elasmobranch (sharks, skates and rays) matrotrophic strategies, and thus potentially diverse pathways for maternal-fetal hormone exchange, little attention has been given to uterine steroids during development. Round Stingrays (Urobatis halleri) with matrotrophic histotrophy were captured during every month of their annual reproductive season from post-ovulation to near parturition, and paired samples of plasma and histotroph were analyzed for a suite of steroid hormones using LC-ESI/MRM. Hormone concentrations within and between maternal and uterine compartments were compared using two markers of embryo development. Read More

Chan School of Public Health, Boston (H.-O.A.); and the Clinical Effectiveness Research Group, Institute of Health and Society, University of Oslo, Oslo (H.-O.A.).

Background: Radical prostatectomy reduces mortality among men with clinically detected localized prostate cancer, but evidence from randomized trials with long-term follow-up is sparse.

Methods: We randomly assigned 695 men with localized prostate cancer to watchful waiting or radical prostatectomy from October 1989 through February 1999 and collected follow-up data through 2017. Cumulative incidence and relative risks with 95% confidence intervals for death from any cause, death from prostate cancer, and metastasis were estimated in intention-to-treat and per-protocol analyses, and numbers of years of life gained were estimated.

Exploring the role of antigen presenting cells in male genital tract.

Andrologia 2018 Dec;50(11):e13120

Universidad de Buenos Aires, Facultad de Medicina, Departamento de Biología Celular e Histología/Unidad Académica II., Buenos Aires, Argentina.

Antigen presenting cells (APCs) are a critical mediator between innate and adaptive immune response. APCs have diverse functions in physiological and pathological conditions, such as maintenance of tissue homoeostasis, prevention of autoimmunity and defence against pathogenic microorganisms and cancer cells. Dendritic cells (DCs) and macrophages (Mϕs) are "professional" APCs that internalise and process allo- and autoantigens; then, resulting peptides are exhibited together with major histocompatibility complex (MHC) molecules expressed at the cell surface.
