Efecto de la Vitamina E en Células Peritubulares de Testículos de Ratones Mus musculus Tratados con Ácido Valproico Durante el Estado Fetal y Pubertad

Int. j. morphol; 41 (6), 2023
El ácido valproico (VPA) es un fármaco antiepiléptico teratógenico que, al ser administrado durante etapas tempranas del embarazo, puede producir alteraciones en el desarrollo embriofetal, las que se manifiestan tanto a nivel del sistema nervioso como del testículo. No obstante, se ha reportado que ...

The effectiveness of insulin therapy in the functional and morphological recovery of leydig cells in rats submitted to Diabetes mellitus

Biosci. j. (Online); 39 (), 2023
The effects of systemic insulin administration at different concentrations on the testicular tissue of diabetic adult rats, induced by streptozotocin, are evaluated by the morphological analysis of spermatogenic process. Twenty-four adult male rats were divided into 1) Control Group: they received citrat...

Gonadal differentiation during embryonic and fetal development of male New Zealand rabbits (Oryctolagus cuniculus)

Int. j. morphol; 39 (5), 2021
SUMMARY: The rabbit is considered an ideal animal model for studies that describe abnormalities in the testicles due to the similar morphogenetic mechanisms of sexual development and diseases commonly found in humans. The aim of this study was to determine the male sexual differentiation of the New Zeala...

Effects of Corchorus olitorius and protacatechuic acid on diabetic rat testis tissue

Int. j. morphol; 38 (5), 2020
SUMMARY: The aim of this study is to investigate the effects of Protocatechuic acid and Corchorus olitorius on streptozotocin (STZ) induced diabetic rat testis tissue. Randomly selected Wistar Albino rats were divided into five groups as; Diabetes Mellitus, Diabetes Mellitus treated with Corchorus Olitor...

Testicular features of semi-confined Nellore bullssubjected to immunocastration

This study aimed to evaluate the effect of immunocastration on the scrotal circumference, as well as in the macroscopic and microscopic testicular features in Nellore bulls bred under a semi-confining system for 91 days. Sixty animals were divided into two groups: 30 intact animals (non-vaccinated) and 3...

Effects of ketoprofen in spermatogenesis of mice exposed to continuos hypobaric hypoxia

Int. j. morphol; 37 (4), 2019
Hypoxia hypobaric (HH) can cause alterations at testicular level, with temperature increase, intrascrotal alteration and deterioration of spermatogenesis. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ketoprofen have anti-angiogenic properties, and can decrease testicular abnormalities. The objec...

Stereological and morphological analysis of the effects of aging on spermatogenesis in rat testis

Acta cir. bras; 33 (10), 2018
Abstract Purpose: To quantify, through stereological and morphometric analysis, spermatogenesis in rats undergoing the natural aging process. Methods: Seventy-two male Wistar rats were divided into 6 equal groups according to age at the time of killing: 3, 6, 9, 12, 18, and 24 months. All the rats were...

Influence of prolonged flaxseed ( Linum usitatissimum ) consumption over epididymis and testicle histoarchitecture of Wistar rats

Pesqui. vet. bras; 37 (6), 2017
Flaxseed is considered a functional food with several health benefits. However, because of its high phytoestrogen content, flaxseed influences hormone metabolism and affects the gonadal biomorphology. In this study, computerized histomorphometry was used to evaluate seminiferous and epididymal tubules, c...

Short-term buserelin administration induces apoptosis and morphological changes in adult rat testes

Acta cir. bras; 32 (2), 2017
Abstract Purpose: To investigate the effect of buserelin on gonadal structure and function in adult male rats. Methods: Twenty-four adult Wistar male rats were divided into three groups: two treated groups and controls. The first and second treated groups received 300 (low dose) and 500 (high dose) µ...

Morfologia do escroto, do testículo e das vias espermáticas de Metachirus nudicaudatus (Geoffroy, 1803), Didelphidae-Marsupialia

Pesqui. vet. bras; 35 (supl.1), 2015
Foram utilizadas as gônadas e vias espermáticas de cinco animais machos, adultos em fase reprodutiva, da espécie Metachirus nudicaudatus Geoffroy 1803, única espécie do gênero, para descrever a morfologia do escroto, do testículo e das vias espermáticas. O Metachirus possui escroto pré-peniano e...
