The association between sexual dysfunction and prostate cancer: a systematic review and meta-analysis

Abstract

Background Whether there is a connection between sexual dysfunction (SD) and prostate cancer (PCa) is controversial. Aim We sought to review the interrelationship between SD and PCa and to determine whether there is a definitive risk of men developing PCa after suffering from SD. Methods A complete search of the PubMed, Web of Science, Ovid MEDLINE, Embase, and Cochrane Library databases was performed to search for eligible studies published up to October 2022. The protocol for this meta-analysis is available from PROSPERO (ID: CRD42022342381). Outcomes The associations between SD and the risk of PCa were assessed by calculating pooled ORs with 95% CIs, and the standard mean difference (SMD) and its 95% CI were used to assess the relationship between SD and prostate-specific antigen (PSA) levels or prostate volume (PV). Random-effects models were used to account for potential heterogeneity, and the Newcastle–Ottawa Scale (NOS) was used to evaluate the quality of the included studies. Results Twenty studies involving 215,626 individuals were included in our meta-analysis. Compared with controls, subjects with SD had a 1.62-fold increased risk of PCa (OR = 1.62, 95% CI, 1.77-2.23, P = .003; heterogeneity: I2 = 97.8%, P < .001). Patients with SD had higher PSA levels than controls (SMD =0.07, 95% CI, 0.00 to 0.13, P = .041; heterogeneity: I2 = 55.6%, P = .027). However, there was no association between SD and PV (SMD = 0.03, 95% CI, −0.05 to 0.11, P = .122; heterogeneity: I2 = 48.5%, P = .100). Clinical Implications Current evidence confirms a potential link between SD and the risk of PCa and that SD in PCa patients should be of concern to clinicians. Strengths and Limitations The strength of this study is that it is to our knowledge the first meta-analysis of studies on the risk of PCa in men with SD. A limitation is that most of the studies included in this meta-analysis focused on ED. Conclusion Our systematic review and meta-analysis results suggest that men with SD have a higher risk of PCa and higher PSA levels than men without SD. However, this is merely inferential, and causality cannot be determined based on the current data. Further longitudinal studies should be performed to validate our preliminary findings.

Association between leucocyte telomere length and erectile dysfunction in US adults: a secondary study based on 2001–2002 NHANES data

“…The development and progression of ED is directly and indirectly influenced by a variety of cancers, particularly prostate cancer. Radical prostatectomy and prostate radiation therapy can cause ED,45 46 and ED is a potential cause of prostate cancer 47. Although we excluded prostate cancer patients from our study, it is not clear whether the telomere length in some ED patients is altered by the development of cancer.…”

Sexual dysfunction in men and women with arterial hypertension

“…Связь между артериальной гипертензией и сексуальной дисфункцией. Аг является широко распространённым заболеванием и известным фактором риска сексуальной дисфункции как у мужчин, так и у женщин [25,26]. несмотря на неоспоримые успехи в развитии фармакологической терапии Аг и широкое назначение антигипертензивных препаратов, лишь небольшая часть пациентов достигает стабильного поддержания целевых уровней Ад [27].…”

Causal associations between prostate diseases, renal diseases, renal function, and erectile dysfunction risk: a 2-sample Mendelian randomization study

“… 5 In the field of urology and andrology medicine, several previous studies have indicated a correlation between prostate disease and ED, 6 , 7 suggesting the presence of shared underlying factors. 8 In patients with prostate cancer (PCa), the presence of inflammation and increased levels of reactive oxygen species are linked to reduced blood flow necessary for achieving a penile erection. 9 In addition, various treatment options currently available, such as radical prostatectomy and radiotherapy, carry the risk of causing ED.…”
