Hyperthyroidism as an Underlying Cause of Premature Ejaculation

INTRODUCTION

Hormonal imbalances have been associated with various sexual dysfunction disorders. In particular, the connection of hyperthyroidism has been discovered to correlate to premature ejaculation (PE) but has yet to been thoroughly elucidated. As one of the most frequently self-reported sexual dysfunctions, it is imperative for health care professionals to evaluate possible underlying conditions in regard to treatment options for individuals with PE.

OBJECTIVES

To review the literature regarding hyperthyroidism effects on sexual dysfunction, with a focus on hyperthyroidism and PE.

METHODS

A literature review of articles and clinical studies was performed to define the classification, pathophysiology, diagnostic considerations, and management of hyperthyroidism on PE. Search terms included "hyperthyroidism" and/or "premature ejaculation," "treatment of premature ejaculation," "defining premature ejaculation," and "management of premature ejaculation."

RESULTS

To improve the accuracy of diagnosing PE, there needs to be a set definition amongst the different guidelines, as using these guidelines can help determine possible underlying etiologies of PE. The correlation of hyperthyroidism and PE has been described in a limited number of studies. It has been reported that individuals with hyperthyroidism are much more likely to have PE than individuals with euthryoidism. Management of hyperthyroidism has been shown to alleviate the symptoms of PE.

CONCLUSION

Further understanding of hyperthyroidism as an underlying cause of PE could lead to increased efficacy of treatment and management of PE. Tannenbaum J, Youssef M, Attia AS, et al. Hyperthyroidism as an Underlying Cause of Premature Ejaculation. Sex Med Rev 2021;XX:XXX-XXX.

Biological markers of harm can be detected in mice exposed for two months to low doses of Third Hand Smoke under conditions that mimic human exposure

Third-hand smoke (THS) is a recently discovered environmental health hazard that results from accumulation and aging of second-hand smoke (SHS) toxins on surfaces of environments where smoking has occurred. Our objective was to determine whether there is a dose-dependent effect of THS exposure on biological markers of harm (BMH) using an in vivo exposure system that mimics exposure of humans to THS. THS exposure generated from as low as the 10 cigarettes-smoking regimen, resulted in increased circulating inflammatory cytokines, tumor necrosis factor alpha, interleukin 1 alpha, and granulocyte macrophage colony-stimulating factor. We also found that there was an increase in adrenocorticotropic hormone and superoxide dismutase and a decrease in ATP levels in liver tissue. Many of the altered BMH that are related to oxidative stress and decrease in ATP levels, suggest mitochondrial dysfunction. THS exposure generated from the 20 and 40 cigarettes-smoking regimen resulted in further damage. Our studies are important because virtually nothing is known about the physiological damage caused by different levels of THS exposure. These studies can also serve to educate the public on the dangers of THS and the BMH we identified can potentially be used in the clinic, once verified in exposed humans.
