INTRODUCTION PDE5 inhibitors (PDE5inhs) have proven to be of great impact in the treatment of numerous human extra-sexual diseases and their chronic use may induce endothelial rehabilitation. This study aimed to assess the effects of PDE5inhs at chronic administration to explore the possible endothelial cyto-protective and thrombo-resistance effects. MATERIAL AND METHODS One hundred New Zeala...

CONTEXT A large body of epidemiologic data suggests a causal relationship between lower urinary tract symptoms (LUTS) and erectile dysfunction (ED). Recently reported studies on phosphodiesterase type 5 inhibitors (PDE5-Is) and LUTS have further contributed to the understanding of mechanisms involved in this relationship and of potential treatment options. OBJECTIVE A nonsystematic descriptiv...

Background: Low levels of testosterone and sexual desire loss are common characteristics hypogonadism, which is an endocrine disorder often occurring in men. Sexual dysfunction uncomfortable condition that both hypogonadal diabetic men experience nowadays, however the diagnosis treatment strategies limited. Type II diabetes a lifelong abnormal glucose metabolism with devastating health effects ...

The aim of this review study is to elucidate the effects that phosphodiesterase 5 (PDE5) inhibitors exert on spermatozoa motility, capacitation process and on their ability to fertilize the oocyte. Second messenger systems such as the cAMP/adenylate cyclase (AC) system and the cGMP/guanylate cyclase (GC) system appear to regulate sperm functions. Increased levels of intracytosolic cAMP result i...

Pulmonary arterial hypertension (PAH) is a rare disease characterized by vascular proliferation and remodeling, resulting in a progressive increase in pulmonary arterial resistance, right heart failure, and death. The pathogenesis of PAH is multifactorial, with endothelial cell dysfunction playing an integral role. This endothelial dysfunction is characterized by an overproduction of vasoconstr...

PURPOSE Characterize persistence and adherence to phosphodiesterase type - 5 inhibitor (PDE5I) on-demand therapy over 6 months among Brazilian men in an observational, non-interventional study of Latin American men naïve to PDE5Is with erectile dysfunction (ED). MATERIALS AND METHODS Men were prescribed PDE5Is per routine clinical practice. Persistence was defined as using ≥ 1 dose during the...
