Metabolic syndrome (MetS) and andrological diseases share common risk factors and common patho-physiological mechanism. In this brief review we describe the relation between metabolic syndrome and male sexual disorders, and we explore the available evidence of the pathophysiological mechanisms correlating these conditions. The aim of this study was to describe the relation between metabolic syndrome and andrological diseases. ⋯ Strong associations are seen between male sexual dysfunction and central obesity, poor glycemic control, hyperlipidemia, as well as hypertension. The constellation of risk factors leading to metabolic syndrome are linked to male sexual dysfunction and are largely modifiable. Therefore, effective interventions targeting the underlying pathophysiology have the potential to greatly impact and improve patient sexual function and, ultimately, quality of life.

Historically, urologists regarded prostate enlargement as the sole cause for male bladder problems. Over time, subdivision of symptoms into storage, voiding and post-voiding symptoms raised awareness of the urinary tract fine-tuning associated with urine storage and voiding, and led to the umbrella term lower urinary tract symptoms (LUTS), which respects bladder and prostate function. While research goes on, it seems as if the more we know about urine storage and voiding, the more complicated it gets: different mechanism can mimic the same symptoms. Clinically, it remains ever the more challenging to understand the pathophysiological context of each patient. Metabolic syndrome (MetS), too, is an umbrella term. Metabolic changes caused by MetS pathophysiologically start with visceral adiposity. It leads to different changes in the signaling pathway including cytokines, elevated transmitters of inflammation, higher levels of free fatty acids (FFA), and adipokines, resulting in vasoconstriction, insulin resistance, impaired glucose uptake and high insulin secretion. Furthermore, MetS is thought to be associated with nephrolithiasis, BPH, LUTS, erectile dysfunction (ED), and infertility. This review aims at synthesizing interactions and consequences of LUTS with MetS. ⋯ Inflammation links both umbrella terms, LUTS and MetS. Understanding the exact role of the different elements will not only help to better understand both findings, but also lead to more efficacious treatment, and hopefully, in the future, personalized medicine, by understanding each individual's driving mechanism for LUTS. Reducing inflammation is likely to help patients with MetS and LUTS; further research could therefore focus on how to manage inflammation.
