Modulatory effects of ghrelin on sperm quality alterations induced by a fructose-enriched diet
(Elsevier Ltd, 2019-11)
The objectives of this study were: 1) to evaluate the effects of a fructose enriched diet (FED) on rat3 sperm quality, epididymal function (i.e. oxidative stress and alpha-glucosidase expression) and4 testosterone ...
Innate immunity in the male genital tract: Chlamydia trachomatis induces keratinocyte-derived chemokine production in prostate, seminal vesicle and epididymis/vas deferens primary cultures
(Society for General Microbiology, 2011-03)
Chlamydia trachomatis is an intracellular pathogen that infects mucosal epithelial cells, causing persistent infections. Although chronic inflammation is a hallmark of chlamydial disease, the proinflammatory mechanisms ...
CRISP (Cysteine Rich Secretory Proteins) as novel regulators of epididymal epithelium differentiation
(Epididymis 7, 2019)
Epididymal CRISP1 and CRISP4 associate with the sperm surface during maturation and are key mediators of fertilization. Whereas single knockout (KO) males for these molecules showed in vitro sperm fertilizing defects but ...
Sperm viability percentage by flow cytometry during the cryopreservation process in spermatozoa obtained from alpaca epididymisDeterminación del porcentaje de viabilidad espermática mediante citometría de flujo durante el proceso de criopreservación en espermatozoides obtenidos de epidídimo de alpaca

Los Conjugados de Espermatozoides (Asociación de Varios Espermatozoides en el Epidídimo) Alcanzan la Zona de Fertilización en la Rata, pero Fecunda sólo un EspermatozoideSperm Conjugates (Association of Several Sperm in the Epididymis) Reach Zone Fertilization in Rats, but Fertilizes Only One Sperm
(Universidad Autónoma de Chile, 2015-11)
En mamíferos se produce el fenómeno de conjugación espermática, tanto dentro del epidídimo como post eyaculación. Los conjugados espermáticos consisten en decenas hasta cientos de espermatozoides asociados. La conjugación ...
Impaired male fertility and abnormal epididymal epithelium differentiation in mice lacking CRISP1 and CRISP4
(Nature Publishing Group, 2018-12)
Epididymal Cysteine Rich Secretory Proteins 1 and 4 (CRISP1 and CRISP4) associate with sperm during maturation and play different roles in fertilization. However, males lacking each of these molecules individually are ...
Anatomy and Histology of the Male Reproductive Tract and Spermatogenesis Fine Structure in the Lesser Anteater ( Tamandua tetradactyla , Myrmecophagidae, Xenarthra): Morphological Evidences of Reproductive Functions
(Wiley Blackwell Publishing, Inc, 2013-08)
The anatomy and histology of the male genital tract of the lesser anteater were studied. Fine details of spermatozoa regarding their genesis and morphology were also studied in six adult specimens. The testes lie in the ...
