Sperm motility and lipid composition in internally fertilizing ocellate river stingray Potamotrygon motoro.

Theriogenology 2019 Mar 2;130:26-35. Epub 2019 Mar 2.

University of South Bohemia in České Budějovice, Faculty of Fisheries and Protection of Waters, Bohemian Research Center of Aquaculture and Biodiversity of Hydrocenoses, Zátiší 728/II, 389 25, Vodňany, Czech Republic. Electronic address:

All extant groups of Elasmobranches have internal fertilization and the structure of the male reproductive organs is very specific: sperm passes from the internal organs via the cloaca, but the male copulating organ (clasper) is distant from the cloaca. This suggests that sperm can contact the surrounding medium before fertilization. Because of this involvement with the environment, external signaling in sperm motility activation could occur in these species even though their fertilization mode is internal. Read More

Heterochrony of puberty in the European badger (Meles meles) can be explained by growth rate and group-size: Evidence for two endocrinological phenotypes.

PLoS One 2019 6;14(3):e0203910. Epub 2019 Mar 6.

Wildlife Conservation Research Unit, Department of Zoology, University of Oxford, Oxford, United Kingdom.

Puberty is a key stage in mammalian ontogeny, involving endocrinological, physiological and behavioural changes, moderated by intrinsic and extrinsic factors. Thus, not all individuals within one population achieve sexual maturity simultaneously. Here, using the European badger (Meles meles) as a model, we describe male testosterone and female oestrone profiles (using Enzyme-immunoassays) from first capture (3 months, post-weaning) until 28 months (attaining sexual maturity and final body size), along with metrics of somatic growth, scent gland development and maturation of external reproductive organs as well as intra-specific competition.

Why do normal children have acromegalic levels of IGF-I during puberty?

J Clin Endocrinol Metab 2019 Mar 6. Epub 2019 Mar 6.

Department of Growth and Reproduction, Rigshospitalet, University of Copenhagen.

Context: The rapid pubertal height growth is unique to humans, but why do we have it? Although the spurt contributes 13-15% to the final adult height, we hypothesize that the biological significance of the high acromegalic levels of GH and IGF-I which are behind the pubertal growth spurt may primarily be to stimulate reproductive organs.

Evidence Synthesis: Animal data demonstrate that adult Igf1 and Igf2 gene knockout mice that survive show a dramatic reduction in the sizes of reproductive organs, and are infertile. In humans, case reports of mutations in genes affecting the GH-IGF axis and growth (GH, GHRH, GH-R, STAT5b, IGF-I, IGF-II, IGF-1R, PAPPA2) are also characterized by delayed pubertal onset and micro-penis.

Physiological and anatomical aspects of the reproduction of mice with reduced Syndecan-1 expression.

Reprod Biol Endocrinol 2019 Mar 2;17(1):28. Epub 2019 Mar 2.

Department of OB/GYN and REI (UniKiD), University Hospital Düsseldorf, Moorenstraße 5, 40225, Düsseldorf, Germany.

Background: Syndecan-1 is a heparan sulfate proteoglycan acting as a co-receptor for cytokines and growth factors mediating developmental, immunological and angiogenic processes. In human, the uteroplacental localization of Syndecan-1 and its reduced expression in pregnancy-associated pathologies, such as the intrauterine growth restriction, suggests an influence of Syndecan-1 in embryo-maternal interactions. The aim of the present study was to identify the effect of a reduced expression of Syndecan-1 on the reproductive phenotype of mice and their progenies. Read More

Taste Receptors: New Players in Sperm Biology.

Int J Mol Sci 2019 Feb 22;20(4). Epub 2019 Feb 22.

Department of Molecular and Developmental Medicine, Siena University, 53100 Siena, Italy.

Taste receptors were first described as sensory receptors located on the tongue, where they are expressed in small clusters of specialized epithelial cells. However, more studies were published in recent years pointing to an expression of these proteins not only in the oral cavity but throughout the body and thus to a physiological role beyond the tongue. The recent observation that taste receptors and components of the coupled taste transduction cascade are also expressed during the different phases of spermatogenesis as well as in mature spermatozoa from mouse to humans and the overlap between the ligand spectrum of taste receptors with compounds in the male and female reproductive organs makes it reasonable to assume that sperm "taste" these different cues in their natural microenvironments.

Multiple neuropeptides produced by sex-specific neurons control activity of the male accessory glands and gonoducts in the silkworm Bombyx mori.

Sci Rep 2019 Feb 19;9(1):2253. Epub 2019 Feb 19.

Institute of Zoology, Slovak Academy of Sciences, Dúbravská cesta 9, 84506, Bratislava, Slovakia.

The male accessory glands (AG) and gonoducts of moths develop during metamorphosis and are essential for successful fertilization of females. We found that these reproductive organs are innervated by a sex-specific cluster of peptidergic neurons in the posterior 9 neuromere of the terminal abdominal ganglion (TAG). This cluster of ~20 neurons differentiate during metamorphosis to innervate the accessory glands and sperm ducts. Read More

Functional morphology of Trichadenotecnum male and female genitalia analyzed using μCT (Insecta: Psocodea: Psocomorpha).

J Morphol 2019 Apr 18;280(4):555-567. Epub 2019 Feb 18.

Systematic Entomology, Graduate School of Agriculture, Hokkaido University, Sapporo, Japan.

Although the great genital diversity of the barklouse genus Trichadenotecnum has been described in previous studies, the specific function of the genital structures during the copulation process has received less investigative attention. We reconstructed 3D-models of each structure of the male and female genitalia of Trichadenotecnum incognitum in copula and those of uncopulated male and female of Trichadenotecnum pseudomedium. By comparing the changes in male and female genital structures and related muscles in copulated and uncopulated states, the function of each genital structure can be described. Read More
