Abstract
Abstract
Background
Erectile dysfunction (ED) demonstrates seasonal variation with higher rates in winter, and we hypothesize that endothelial damage in erectile tissue caused by bradykinin receptor B1 (B1R) might be detrimental to this change.
Aim
To find out direct correlations between cold stress and ED, through which to further investigate the functional roles of B1R in erectile tissue and to elucidate the therapeutic roles of the B1R antagonist in a cold stress–induced ED rat model.
Methods
Cold stress rat models are established through long-term intermittent exposure to low temperature. After their erectile function was assessed, ED rats were treated with the B1R antagonist through intraperitoneal injection. Penile tissues were obtained at the end of the experiment after measurement of intracavernosal pressure/mean arterial pressure (ICP/MAP); the location and distribution of cytokine expression were determined by immunohistochemistry; cytokine levels and NOS and CD31 expression were detected by Western blotting; and collagen fibers and smooth muscles were observed through Masson staining.
Outcomes
Cold stress impairs erectile function, and the B1R antagonist protects against it.
Results
We observed decreased erection frequency, prolonged erection latency time, decreased ICP/MAP, overexpression of B1R, increased expression of cytokines on cavernous sinus endothelium, and increased levels of collagen fibers/smooth muscles on erectile tissue in response to cold stress. Also, NOS and CD31 expression was downregulated. B1R antagonist treatment shows enhanced erectile function through increased erection frequency, shortened erection latency time, and increased ICP/MAP. Also, it reduces collagen fibers/smooth muscles, TNF-α, TGF-β1, and IL-6 and upregulates the expression of nNOS and CD31.
Clinical Translation
Our findings cast new light on the correlations between cold stress and erectile function and potential new applications of existing B1R antagonist drugs in the field of ED.
Strengths and Limitations
Our data support that cold stress impairs erectile function. B1R-mediated, cytokine-induced corpus cavernosum fibrosis and endothelial damage might be the main reason behind it, and B1R inhibition protects against fibrosis and endothelial damage. Other ways of B1R antagonist blocking methods in different types of ED still need to be investigated.
Conclusion
Long-term intermittent cold stress impairs erectile function, and B1R-mediated, cytokine-induced corpus cavernosum fibrosis and endothelial damage might be the main reason behind it. B1R inhibition also protects against fibrosis and endothelial damage. Our data support the hypothesis that cold stress impairs erectile function and that B1R blockade ameliorates the symptoms of ED, possibly by reversing fibrosis and endothelial damage in erectile tissue.

Andrologia 2021; 53:e14142. [PMID: 34105178 PMCID: PMC8459256 DOI: 10.1111/and.14142] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Accepted: 05/25/2021] [Indexed: 01/21/2023] Open
Abstract
In the present study, we aimed to evaluate the association between asexual trait, erectile dysfunction (ED) and porn addiction in a community sample of young men. Between August 2019 and October 2019, a total of 559 young male adults were subjected to an online survey sponsored by social networks with the aim of assessing their sexual habits. The following questionnaires were administered: The International Index of Erectile Function (IIEF-5), Masturbation Erection index (MEI), Pornography Craving Questionnaire (PCQ) and Asexuality Identification Scale (AIS). The overall rate of ED according to IIEF-5 was 26.0% (165/478), the rate of ED according to MEI was 16.9% (81/478) and the rate ED in patients with AIS ≥23 indicating asexual trait was 10.0% (48/478). We found that IIEF-5 was positively associated with MEI (b = 0.32; p < .01) and negatively with AIS (b = -0.36; p < .01) and MEI was negatively associated with AIS (b = -0.36; p < .01). We found that MEI (odds ratio [OR]: 0.86; p < .01) and IIEF-5 (OR: 0.89; p < .01) were inversely associated with asexual trait. The presence of asexual trait can hide a greater risk of finding ED both in intercourse or masturbation. These results should be taken into consideration during the general assessment of the patient with sexual problems.
