First, the bioinformatics database was used to predict the potential targets and signaling pathways of pulmonary fibrosis (PF) leading to erectile dysfunction (ED), and bleomycin sulfate was used to create a PF rat model. Then, enzyme-linked immunosorbent assay (ELISA), Western blotting, Real-time fluorescent quantitative reverse transcription polymerase chain reaction (RT-qPCR) were used to detect the expression of sex hormones and related proteins and mRNA, and Hematoxylin and eosin (H&E) staining was used to compare the pathological changes of penile tissue. The results showed that, compared with group A, cyclic guanosine phosphate (cGMP) content in group B decreased, protein kinase CGMP-dependent 1(PKG1) and nitric oxide synthase 3 (eNOS) protein and mRNA expression were down-regulated, and phosphodiesterase 5A (PDE5A) protein and mRNA expression was up-regulated (p < .05); the penile tissue of rats in group B had pathological damage. And there was no change in sex hormone-related indicators in the two groups (p > .05). Therefore, PF inhibits erectile function by inhibiting the cGMP-PKG pathway and reducing the expression of eNOS and PKG1 protein and mRNA. And by up-regulating the expression of PDE5A to impair erectile function.

Background: Benign prostatic hyperplasia (BPH) is a common disease in middle-aged and elderly men, and its etiology is not completely clear. Late-onset hypogonadism (LOH) is a relatively common disease in the aging process of men. BPH is often accompanied by varying degrees of LOH, and the pathogenesis and progression of the two diseases are related.

Two novel phosphodiesterase 5 (PDE-5) inhibitors were detected in pressed candy using high-performance liquid chromatography (HPLC)-diode array detection. Following extraction with acetonitrile and sonication, the compounds were isolated and purified semi-preparative liquid chromatography. Structural characterisation was achieved through high-resolution mass spectrometry (HRMS) and nuclear magnetic resonance (NMR) spectroscopy.

Introduction: Water vapor thermal therapy (WVTT; REZUM™; Boston, USA) offers symptom relief with reduced risks of complications in patients with lower urinary tract symptoms (LUTS) related to benign prostatic obstruction (BPO). WVTT therapy has been validated in the pivotal study in men with smaller prostates (< 80 cc). Yet, its feasibility for larger prostates (≥ 80 cc) remains underexplored.

Introduction: Exercise is a simple, safe, and affordable solution that can be easily taught to men with chronic illnesses to improve their psychological burden and sexual health.
Aim: Since the role of exercise in ameliorating the psychological burden associated with erectile dysfunction (ED) in hepatitis C (HC) men was not explored, this research aimed to explore this role.
Material And Methods: This HC study was a randomized-controlled exercise-rehabilitation trial.

Background: While previous studies have explored the associations and causalities among platelet count (PC), mean platelet volume (MPV), and erectile dysfunction (ED), further investigations are needed to clarify these relationships using advanced methodologies and analyzing specific populations.
Aim: To investigate the associations and causalities among PC, MPV, and ED using observational study and Mendelian randomization (MR) analysis.
Methods: A total of 114 patients with ED and 158 healthy control participants underwent a fasting blood draw to test for PC and MPV along with a comprehensive laboratory examination.
