Effect of aerobic exercise on erectile function: systematic review and meta-analysis of randomized controlled trials

Synergistic Effects of Vitamin D and Exercise on Diabetes-induced Gonadotoxicity in Male Wistar Rats: Role of Xanthine Oxidase/Uric Acid and Nrf2/NfkB Signaling

Type 2 Diabetes mellitus (T2DM) is one of the oldest known chronic diseases, characterized by elevated fasting blood sugar (FBS). T2DM is a metabolic disorder that can distort the activities of multiple physiological systems, including the reproductive system. Although different drugs have been designed for managing this disorder, these drugs have been reported to have negative side effects. Hence, this study was designed to explore the possible synergistic effect of vitamin D and exercise on T2DM-induced testicular dysfunction. Thirty-six male Wistar rats were randomized into six (6) groups: control, diabetes untreated, diabetes treated with 1000 IU/kg of vitamin D, diabetes treated with 5 min/day of physical exercise, diabetes treated with vitamin D and exercise, diabetes treated with 180 mg/kg of metformin. T2DM induction led to a significant increase in FBS, lactate, and lactate dehydrogenase, and was reversed by vitamin D supplementation and exercise. Also, vitamin D and exercise synergistically blunted T2DM-induced oxido-inflammatory response evidenced by a significant decrease in testicular malondialdehyde, interleukin 1β, interleukin 6, and tumor necrosis factor alpha, and an increase in superoxide dismutase, catalase, glutathione peroxidase, and interleukin 10. These events were associated with a decrease in T2DM-induced increase in XO, UA, and Nf-κb and an increase in T2DM-induced decrease in Nrf2. Also, vitamin D and EX reversed the observed impairment in sperm quality and testicular histology following T2DM-induction. This study revealed the synergistic effect of vitamin D and exercise on T2DM-induced testicular dysfunction.

Prevalence and trends in physical therapy interventions for erectile dysfunction: A Scopus-based bibliometric analysis (1989-2022)

BACKGROUND

Erectile dysfunction (ED) is a condition that affects many males. Physical therapy (PT) is the one potential treatment for ED that may improve blood flow, muscle strength, and other factors that may contribute to the issue. Data on the prevalence and trends of research on PT for ED are lacking.

OBJECTIVE

This study aimed to evaluate the literature trends in PT for ED via bibliometric and visualized analysis.

METHODS

Data on publications were collected from Scopus covering the period between 1989 and 2022. To refine the data, bibliometric analyses were conducted using Microsoft Access, Microsoft Excel, an online visualization platform, and BiblioAnalytics. Power BI and Bibliomaster were used to generate figures and tables, while Biblioshiny and VOSviewer were used for visualization.

RESULTS

A total of 494 documents were identified. The year 2019 generated the largest number of publications, with a total of 54. These studies have received 12,917 citations related to PT for ED. The most common document type was the original article with 283 publications. The University of California, USA, was the most productive institution on this topic, with 21 publications and 2,035 citations. The USA led all countries with 114 publications on the topic. The Journal of Sexual Medicine secured the top ranking with an h-index of 18. The main topics studied were erectile dysfunction, shockwave therapy, and physiotherapy.

CONCLUSION

The number of publications on PT for ED has demonstrated an upward trend over the last three decades.

A Systematic Review on the Relationship Between Physical Activity and Sexual Function in Adults

Sexual function is a vital component of overall well-being and quality of life. Physical activity is known to have a profound influence on various aspects of health, but its impact on sexual function in the general population remains an under-explored area. This systematic review seeks to thoroughly examine existing evidence, aiming to establish the correlation between physical activity and sexual function in both male and female adults. We conducted a comprehensive search of electronic databases and relevant sources, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Eligible studies were those that investigated the effects of physical activity on sexual function using the International Index of Erectile Dysfunction (IIEF-5) questionnaire and the Female Sexual Function Index (FSFI). Quality assessment was performed on the included studies, and the findings were synthesized through qualitative analysis. The review identified 12 randomized controlled trials, primarily focusing on males, with interventions ranging from home-based walking to structured exercise training. Only two studies were conducted among females. The most recommended exercise was aerobic exercise. Consistent aerobic exercise proves to be a hopeful and efficient non-drug intervention for enhancing erectile function in men. However, when considering the effects of physical exercise programs on sexual function and the quality of sexual life of females, the results present challenges in drawing clear conclusions. Health policymakers play an important role in providing guidelines and recommendations to healthcare professionals, encouraging them to prescribe exercise as a preferable alternative to pharmacological treatments for enhancing sexual functions in both men and women.
