Leydig and Sertoli cell function in individuals with genital ambiguity, 46,XY karyotype, palpable gonads and normal testosterone secretion: a case-control study

Säo Paulo med. j; 140 (2), 2022
Abstract BACKGROUND: Because normal male sexual differentiation is more complex than normal female sexual differentiation, there are more cases of disorders of sex development (DSDs) with 46,XY karyotype that have unclear etiology. However, Leydig and Sertoli cell markers are rarely used in distinguishi...

The effect of testosterone replacement on intramedullary, inguinal and visceral fat in ovariectomized rats

Abstract Objective The present article aims to evaluate the impact of testosterone treatment on the expansion of visceral, subcutaneous and intramedullary adipose tissue of ovariectomized rats and the visceral and subcutaneous fat expression of peroxisome proliferator-activated receptors (PPARs) gamma....

Imbalance in the diurnal salivary testosterone/cortisol ratio in men with severe obstructive sleep apnea: an observational study

ABSTRACT INTRODUCTION: The complex relationship between sleep disorders and hormones could lead to alterations in the production of cortisol and testosterone in obstructive sleep apnea (OSA) patients. OBJECTIVE: The purpose of this study was to determine the diurnal trajectories of salivary free-testos...

Asociación entre niveles de testosterona, sensibilidad a la insulina, adiposidad y parámetros lipídicos en hombres
Association between testosterone levels, insulin sensitivity, adiposity and lipid parameters in men

Rev. cuba. endocrinol; 26 (2), 2015
Introducción: Evidencias sugieren que la testosterona interviene en la regulación del metabolismo de la glucosa y los lípidos.Objetivo: determinar la relación entre los niveles de testosterona y la sensibilidad a la insulina, la adiposidad y los parámetros del metabolismo lipídico en hombres.Métod...

Efeito mitogênico da testosterona nos ductos granulosos da glândula submandibular do camundongo macho castrado

Semina; 8 (2), 1987
A hipertrofia celular é o mecanismo aceito para a recuperaçäo dos ductos granulosos de camundongos machos castrados, tratados com testosterona (T). No presente trabalho, foi possível demonstrar, que, similarmente ao descrito para outros órgäos-alvo da T, os ductos granulosos respondem, durante sua ...

Efeito de dose única de testosterona na síntese de proteínas pelas células dos ductos granulosos da glândula submandibular do camundongo macho castrado

Semina; 8 (2), 1987
As glândulas submandibulares de camundongos machos castrados mostram uma atrofia do compartimento de ductos granulosos, com reduçäo da síntese protéica por estas células. Neste trabalho, estudamos o efeito de uma única dose de testosterona no estímulo da síntese protéica por estas células. Det...
