Background
The relation between endogenous testosterone concentrations and myocardial mass and function remains incompletely understood.
Objectives
To determine the cross‐sectional association between endogenous hormone levels with cardiac magnetic resonance measures of myocardial mass, structure, and function in community‐dwelling men across a wide age range.
Methods
A total of 720 men from...
Testosterone dose‐dependently increases appendicular muscle mass. However, the effects of testosterone administration on the core muscles of the trunk and the pelvis have not been evaluated. The present study evaluated the effects of testosterone administration on truncal and pelvic muscles in a dose–response trial. Participants were young healthy men aged 18–50 years participating in the 5α‐Reductase...
In a subset of men, sarcopenia and physical dysfunction occur due to destabilization of the neuromuscular junction (NMJ), which is manifested by elevated serum concentrations of C‐terminal agrin fragment (CAF). Testosterone administration improves physical function in some studies; however, its effects on serum circulating CAF concentrations remain unknown. Here we evaluate the effects of testosterone...
Animal data shows that testosterone administration increases the volume of some parenchymal organs. However, the effects of exogenous testosterone on solid abdominal organs in humans remain unknown. The present study evaluated the effects of testosterone administration on the volume of liver, spleen and kidneys in a dose‐response trial. Young healthy men aged 18–50 years participating in the 5α‐Reductase...
Herein, we report the clinical outcomes following intracytoplasmic sperm injection (ICSI) with cryopiece cryopreserved rare human spermatozoa from severe male factor infertility patients. We established a novel cryopiece system on the basis of previous studies. In this study, 126 spermatozoa from four patients with non‐obstructiveazoospermia (NOA) or severe oligozoospermia were stored in cryopiece...
The aim of this study was to describe the prevalence of and risk factors for prostatitis‐like symptoms and its relation to erectile dysfunction (ED) among southern Chinese men. Data were collected from 2790 men attending the Fangchenggang Area Male Healthy and Examination Survey from September 2009 to December 2009. The prostatitis‐like symptoms were assessed by the NIH Chronic Prostatitis Symptom...
Brain dysfunction in erectile dysfunction (ED) has been identified by multiple neuroimaging studies. A recent MRI study indicated grey matter alterations in ED patients. This study aims to investigate the microstructural changes of cerebral white matter (WM) in psychological ED patients and their possible correlations with clinical variables. Twenty‐seven psychological ED patients and 27 healthy subjects...
