Overview of vitamin D deficiency and erectile dysfunction (ED)

Vitamin D deficiency has been linked to a variety of health issues, including erectile dysfunction (ED). Male erectile function is influenced by numerous factors and can be viewed as an indicator of overall health. Epidemiological data have shown that vitamin-D deficiency is also associated with erectile dysfunction.

Epidemiological data on vitamin D deficiency and ED

Research suggests that common mechanisms underlie both cardiovascular disease (CVD) and ED, with vitamin D deficiency (VDD) being closely associated with both disorders. A study found that vitamin D deficiency was present in 35 percent of men with erectile dysfunction, compared to 29 percent of those without erectile dysfunction.

Study on 3,400 American men and the prevalence of vitamin D deficiency and ED

A study analyzed data from more than 3,400 American men aged 20 and older who did not have heart disease. The research found that 30 percent of the men were vitamin D deficient, and 16 percent had erectile dysfunction.

Comparison of vitamin D deficiency in men with and without ED

Vitamin D deficiency was found to be more prevalent in men with erectile dysfunction than in those without it. In men with ED, 35 percent were found to be vitamin D deficient, compared to 29 percent of men without ED.

Optimal vitamin D levels and the prevalence of ED and severe ED

Men with vitamin D deficiency have a significantly greater prevalence of ED and severe ED compared to men who have optimal levels (30 ng/mL or higher) of vitamin D. Vitamin D deficiency has been found to be associated with an increased prevalence of erectile dysfunction, independent of risk factors.

Possible mechanisms linking vitamin D to the anatomy and physiology of the penis

Vitamin D deficiency may weaken erectile function by promoting endothelial dysfunction.

Although the exact mechanism by which vitamin D might regulate the anatomy and physiology of the penis is not yet fully understood, it is known to play a role in vascular health, which can impact erectile function.

Vitamin D's role in vascular health and its relation to ED

Erectile dysfunction is often caused by vascular problems, and vitamin D is known to play a role in vascular health. Vitamin D deficiency is associated with vascular diseases, peripheral arterial disease, nitric oxide, inflammation, calcification, hypertension, and diabetes, all of which are risk factors for ED.

Risk factors for ED associated with vitamin D deficiency

Symptoms of vitamin D deficiency may include fatigue, poor sleep, bone pain or achiness, depression or feelings of sadness, hair loss, muscle weakness, loss of appetite, and increased susceptibility to illness. These symptoms can contribute to a weakened erectile function.

Screening and correcting vitamin D deficiency through lifestyle changes

Vitamin D deficiency is easy to screen for and can be corrected with lifestyle changes such as exercise, dietary changes, vitamin supplementation, and modest sunlight exposure. After supplementation with vitamin D, testosterone levels increased, and erectile function improved. Doses used for supplementation were either 1,250 mcg (50,000 IU) or 2,500 mcg (100,000 IU) given weekly, every two weeks, every three weeks, or monthly.

The need for additional research and randomized controlled clinical trials on treating vitamin D deficiency and improving erectile function

While there is evidence suggesting a link between vitamin D deficiency and erectile dysfunction, more research is needed to establish a causal relationship. Randomized controlled clinical trials could help determine whether treating vitamin D deficiency can improve erectile function and clarify the underlying mechanisms.
