Circulating angiogenic cells (CACs) contribute to repair of the vessel wall and dysfunctional CACs are associated to endothelial dysfunction in men with vascular risk factors (VRFs). We investigated whether inhibition of phosphodiesterase type 5 (PDE5) in men with erectile dysfunction (ED) and VRFs is accompanied to changes of CACs and to changes of(More)
Seminal macrophages are occasionally reported though their relevance in the evaluation of human ejaculate is unknown. Activated macrophages, engaging in sperm phagocytosis (spermiophages), might represent a marker of innate immunosystem activation. We investigated whether the presence of spermiophages in non-leukocytospermic ejaculates from men complaining(More)
OBJECTIVE To define by transmission electron microscopy (TEM) analysis, the prevalence of sperm tail defects of genetic origin among men suffering for a reduced or absent sperm motility. DESIGN A retrospective study. SETTING Andrology Clinic, University of L'Aquila, Italy. PATIENT(S) The 120 ejaculates of infertile men with a forward motility (FM) <(More)
BACKGROUND Obese males frequently present with low androgen levels that may improve after weight loss achieved by bariatric surgery. Laparoscopic sleeve gastrectomy (LSG) has been used often in the last decade as treatment for morbid obesity. The aim of this study was to evaluate modifications in the male reproductive hormone profile after LSG. PATIENTS(More)
Mental stress is a risk factor for cardiovascular events in men with vascular risk factors (VRFs) and is also associated with erectile dysfunction (ED), a frequent complaint of men with VRFs. The aim of this study was to investigate the effect of inhibition of phosphodiesterase-5 or of placebo in men with ED and VRFs on self-evaluated psychological(More)
Obesity, defined as a body mass index (BMI) >30 kg/m2, has seen an important increase in prevalence in the last decades, not only in Europe and the United States, but also in developing countries. It is an established risk factor for numerous pathologic conditions like diabetes mellitus, cardiovascular diseases and cancer, but has also been linked to male(More)
Today cycling is considered a useful form of exercise for reducing cardiovascular risk, but it may also represent a risk factor for erectile dysfunction and perineal-genital paresthesia. These disorders are attributed to the local reduction of oxygen in the perineal-genital area, secondary to the perineal compression. Numerous studies have been carried out(More)
