This study aimed to assess the relationship between 25(OH) levels and erectile dysfunction (ED), particularly arteriogenic ED (A-ED). From September 2020 to January 2022, 150 patients diagnosed with ED by the International Index of Erectile Function-5 (IIEF-5) questionnaire were included. All patients were classified as organic ED and psychological ED by nocturnal penile tumescence and rigidity (NPTR) examination. Organic ED patients were divided into A-ED and NA-ED by penile doppler ultrasound (PDU) examination. Finally, 150 patients complaining of ED were enrolled in our study. 25(OH)D levels were significantly lower in patients with
- organic ED (18.24 ± 6.04 ng/ml) than in patients with
- psychogenic ED (20.90 ± 8.79 ng/ml) (p = 0.032).
In A-ED and NA-ED, the mean of peak systolic flow velocity (PSV) values was
- 18.94 ± 5.28 cm/s and
- 51.57 ± 15.42 cm/s (p < 0.001),
and the mean of 25(OH)D was
- 15.66 ± 5.86 ng/ml and
- 20.48 ± 5.90 ng/ml, respectively (p < 0.001).
The results showed that 25(OH)D levels were positively correlated with IIEF-5 scores and the PSV values in A-ED patients.
The 25(OH)D cut-off value differentiating between A-ED and NA-ED was 15.05 ng/ml. Low 25(OH)D levels may be an independent risk factor for ED, especially A-ED. ED patients should routinely undergo serum 25(OH)D level measurement, and 25(OH)D replacement therapy is necessary for patients with low vitamin D levels.
Senior male COVID-19 patients were 13 X more likely to have ED - Nov 2021

Erectile dysfunction and COVID-19 share similar risk factors, including vascular disruption of integrity, cytokine release, cardiovascular disease, diabetes and obesity.
The aim of this study was to investigate the association between erectile dysfunction and COVID-19 patients.
Odds ratio for erectile dysfunction in patients with a history of COVID-19 with and without comorbidities were calculated using a patients’ registry platform i2b2. ICD-10 diagnoses codes were accessed for queries and data were analyzed using logistic regression.
Patients with COVID-19 were 3.3 times more likely to have erectile dysfunction with 95% CI (2.8, 3.8). The association became stronger with odds ratio 4.8 (95% CI (4.1, 5.7)) after adjusting for age groups.
The odds ratio remained the same after adjusting for smoking status with 3.5 (95% CI (3.0, 4.1)). After adjusting for race, COVID-19 patients were 2.6 (95% CI (2.2, 3.1)) times more likely to have erectile dysfunction. The odds ratio were 1.6, 1.8, 1.9 and 2.3 after adjusting for respiratory disease, obesity, circulatory disease and diabetes, respectively.
COVID-19 and erectile dysfunction are strongly associated even after adjustment for known risk factors and demographics.

Literature support that vitamin-D is important for different systems of the human body including, but not limited to endocrine and immune systems, vasculature and endothelial function of the body. Male erectile function depends on many factors and can be perceived as a health indicator of the body. Epidemiological data have shown that vitamin-D deficiency is also associated with erectile dysfunction. In this review, our aim is to interpret the mechanisms by which vitamin-D might regulate anatomy and physiology of penis. Evidence showed that vitamin-D is needed for an adequate erectile function. Briefly, vitamin-D is crucial for a better healthy body and sexual activity.
Based on the evidence from bench and bed, it was shown that VD is important for erectile function. Measurement of VD in ED patients is very crucial with supplementation as required.
VD supplementation potentially represents a low-cost, low-risk method to treat and prevent ED.
In summary, we need VD starting from the early embryonal days to the end of our lives for a better, healthy and sexually active life

The present study aimed to investigate the association between the severity of erectile dysfunction (ED) and serum 25-hydroxy vitamin D. It also sought to determine the cut-off level of serum 25-hydroxy vitamin D for ED. This study included 130 men who had ED between 2018 and 2019. Patients were divided into three groups according to their scores on the international index of erectile function-5 (IIEF-5) Turkish validated short form questionnaire. The serum 25-hydroxy vitamin D results were compared between the groups. The mean age of the patients was 49.28 ± 13.62 years. Groups 1, 2 and 3 included 44 (33.8%) patients with severe ED, 56 (43.1%) patients with moderate ED and 30 (23.1%) patients with mild ED, respectively. Statistical significance was observed between the groups and serum 25-hydroxy vitamin D levels. A positive correlation was detected between the IIEF-5 scores, serum testosterone and serum 25-hydroxy vitamin D levels.
A cut-off level for serum 25-hydroxy vitamin D was calculated as 27.32 ng/ml. During multivariate analysis, we found that serum 25-hydroxy vitamin D levels were independent prognostic risk factors for decreased IIEF-5 scores. Decreased serum 25-hydroxy vitamin D levels were associated with decreased IIEF-5 scores.
Therefore, vitamin D replacement therapy may improve symptoms.

In the last few years growing evidence highlighted vitamin D (VD) deficiency is one of the several dynamics that associates with increased atherosclerotic cardiovascular (ASCV) diseases.
ASCV diseases and erectile dysfunction (ED) share common risk factors such as
- diabetes mellitus,
- hyperlipidemia, and a
- sedentary lifestyle.
The aim of this review was to summarize current progress in VD research by focusing effect of low VD level on different body systems and erectile function. Here we examine research linking VD deficiency and ED and discuss how VD influences ED and its classic risk factors-factors that also associate to increased ED risk. We also summarize research indicating that VD associates with reduced risk of several nonvascular contributing factors for ED. Available literature demonstrates relatively high rates of low VD serum levels in ED patients. Based on the preclinical and clinical data available in the literature, to date, we infer that VD play a critical role in maintaining erectile function in humans. Nevertheless, this should also be tested through randomized controlled studies on the effect of VD supplementation with larger population.

One mechanism linking low VD levels with ED may be via reduced synthesis of NO. Recently Barassi et al demonstrated a higher presence of VDD in arterial ED patients compared with non-arterial-ED patients and a lower serum VD levels in more severe ED patients.
Both observational and interventional studies have established the presence of an association between VD levels and ED. This relation is more than a simple relation, because there are many risk factors (Figure 2) in the etiology of ED which might be directly caused by VDD.
Vitamin D and nitric oxide production
Penis is a vascular organ, and erections have a vascular basis. NO pathway is known to mediate penile erection. NO is a physiologic signal essential for penile erection, and disorders that reduce NO synthesis or release in the erectile tissue are commonly associated with ED. Sexual stimulation releases neurotransmitters from the corpus cavernosa as well as NO from the endothelial cells of the penis.
Another important mechanism of action of VD seems to be via NO- mediated vascular dilation. NO synthases are a family of enzymes that catalyze the production of NO from L -arginine. Activated VD stimulates the production of substantial quantities of NOS and NO in macrophages produced in bone and in endothelial cells in response to tuberculosis. NO is vital to vascular dilation and thereby important for the inhibition of ED. Because of the presence of VD and VDR in the endothelial cells and the pivotal role of NO and eNOS in the endothelial activity, it is conceivable that an interaction between VD and NO is capable of influencing vascular function. Molinari et al. demonstrated that VD is able to stimulate NO production in human umbilical vein endothelial cells through eNOS activation. The finding of an involvement of VD in NO production by endothelial cells is quite relevant. NO is an essential molecule and serves multiple functions including vasodilatation and many anti-atherogenic properties. Indeed, dysregulation of eNOS activity is thought to contribute to the pathogenesis of certain vascular diseases such as atherosclerosis and hypertension.
Activated VD stimulates the production of NO in endothelial cells and NO synthases which catalyze the production of NO from L-arginine, is a key to vascular dilation and thereby critical for the prevention of ED. Interestingly, the latter study showed that VD response occurs within seconds and, for this reason, it appears that VD has a non-genomic direct effect on endothelial cells. Recently, Andrukhova et al. reported that VD receptor mutant mice are characterized by lower bioavailability of the vasodilator NO due to reduced expression of the key NO synthesizing enzyme i.e. eNOS. Reduction in eNOS ends with endothelial dysfunction, increased arterial stiffness, increased aortic impedance, structural remodeling of the aorta, and impaired systolic and diastolic heart function at advanced ages, independent of changes in the renin-angiotensin system. The latter group demonstrated that VD is a direct transcriptional regulator of eNOS. This may also clarify why endothelium derived, and NO-evoked dilation is reduced nearly 50% in arteries from VD deficient male rats. Under the light of recent scientific researches, unsurprisingly, there exists a higher prevalence of ED among VD deficient patients compared to those with optimal levels.

Introduction: Endothelial dysfunction has been demonstrated to play an important role in pathogenesis of erectile dysfunction (ED) and vitamin D deficiency is deemed to promote endothelial dysfunctions.
Aim: To evaluate the status of serum vitamin D in a group of patients with ED.
Methods: Diagnosis and severity of ED was based on the IIEF-5 and its aetiology was classified as *arteriogenic (A-ED),
- borderline (BL-ED), and
- on-arteriogenic (NA-ED)
with penile-echo-color-Doppler in basal condition and after intracaversous injection of prostaglandin E1. Serum vitamin D and intact PTH concentrations were measured.
Main Outcome Measures: Vitamin D levels of men with A-ED were compared with those of male with BL-ED and NA-ED.
Fifty patients were classified as A-ED, 28 as ED-BL and 65 as NA-ED, for a total of 143 cases. Mean vitamin D level was 21.3 ng/mL; vitamin D deficiency (<20 ng/mL) was present in 45.9% and only 20.2% had optimal vitamin D levels. Patients with severe/complete-ED had vitamin D level significantly lower (P = 0.02) than those with mild-ED. Vitamin level was negatively correlated with PTH and the correlation was more marked in subjects with vitamin D deficiency. Vitamin D deficiency in A-ED was significantly lower (P = 0.01) than in NA-ED patients. Penile-echo-color-Doppler revealed that A-ED (PSV ≤ 25 cm/second) was more frequent in those with vitamin D deficiency as compared with those with vitamin >20 ng/dL (45% vs. 24%; P < 0.05) and in the same population median PSV values were lower (26 vs. 38; P < 0.001) in vitamin D subjects.
Our study shows that a significant proportion of ED patients have a vitamin D deficiency and that this condition is more frequent in patients with the arteriogenic etiology. Low levels of vitamin D might increase the ED risk by promoting endothelial dysfunction. Men with ED should be analyzed for vitamin D levels and particularly to A-ED patients with a low level a vitamin D supplementation is suggested.

Diabetes is an established risk factor for erectile dysfunction (ED). The pathophysiology of ED in diabetic men is multifactorial, but it mainly involves a vascular disorder related to a reduction of endothelial function. Recently, several studies have correlated ED risk factors with vitamin D deficiency. In this study, we evaluate the relationship between 25-hydroxyvitamin D [25(OH)D] levels, erectile dysfunction, and vascular disease, in type 2 diabetes mellitus men (T2DM). In this observational study, 92 T2DM males (58.83 ± 9.73 years) underwent medical history collection, International Index of Erectile Function (IIEF-5) questionnaire, that allows the identification and grading of DE, physical examination, biochemical/hormonal blood tests, and penile echo-color Doppler ultrasonography. T2DM patients with lower 25(OH)D levels (<25 nmol/l) showed higher penile IMT (p < 0.05), waist circonference (p < 0.05), glucose concentrations (p < 0.05), and lower IIEF-5 score (p < 0.005), testosterone concentrations (p < 0.05), and cavernous peak systolic velocity (PSV) (p < 0.05), compared to patients with 25(OH)D >50 nmol/l. 25(OH)D levels were directly correlated with IIEF-5 (R = 0.39; p = 0.0001), testosterone (R = 0.24; p = 0.02), and PSV (R = 0.24; p = 0.04) and inversely with waist (R = −0.33; p = 0.002), HbA1c (R = −0.22; p = 0.03), triglyceride (R = −0.21; p = 0.06), and penile IMT (R = −0.30; p = 0.009). At multivariate analysis, 25(OH)D deficiency remained an independent predictor of DE. We demonstrate a significant association between 25(OH)D deficiency and erectile dysfunction in T2DM men. This association may be due to the influence of 25(OH)D deficiency on cardiovascular risk factor (glycaemia, HDL cholesterol, and triglycerides), testosterone plasma levels and endothelial dysfunction.

Background and aims: Erectile dysfunction (ED) and atherosclerotic cardiovascular disease (ASCVD) share many common risk factors, and vascular ED is a marker for increased ASCVD risk. Low 25-hydroxyvitamin D 25(OH)D concentrations have been associated with increased ASCVD risk, but less is known regarding the relationship of low 25(OH)D with ED. We determined whether 25(OH)D deficiency is associated with ED independent of ASCVD risk factors.
Methods: We performed cross-sectional analyses of 3390 men aged ≥20 years free of ASCVD who participated in NHANES 2001–2004. Serum 25(OH)D was measured by the DiaSorin radioimmunoassay; deficiency was defined as levels <20 ng/ml (<50 nmol/L). Self-reported ED, assessed by a single validated question, was defined as men who reported being “never” or “sometimes able” to maintain an erection. We assessed the relationship between 25(OH)D deficiency and ED prevalence using adjusted Poisson regression methods.
Results: After accounting for NHANES sampling, the weighted prevalence of 25(OH)D deficiency and of ED were 30% and 15.2%, respectively. 25(OH)D levels were lower in men with vs. those without ED (mean 22.8 vs 24.3 ng/mL, respectively; p = 0.0005). After adjusting for lifestyle variables, comorbidities, and medication use, men with 25(OH)D deficiency had a higher prevalence of ED compared to those with levels ≥30 ng/ml (Prevalence Ratio 1.30, 95% CI 1.08–1.57).
Conclusion: In this cross-sectional analysis of a representative sample of U.S. men, vitamin D deficiency was associated with an increased prevalence of ED independent of ASCVD risk factors. Additional research is needed to evaluate whether treating vitamin D deficiency improves erectile function.
