Vitamin D plays a vital role in maintaining good health. It is essential for the functioning of many organs of the human body, including bones. Vitamin D is a fat-soluble vitamin that is found naturally in food such as mushrooms, egg yolk, and fish oil. It can also be produced through ultraviolet rays when the skin gets exposed to sunlight. Apart from maintaining the health of the bones, Vitamin D is also involved in different processes such as regulation of cellular growth, immune function, glucose metabolism, and neurological disorder. When the body doesn’t get enough Vitamin D to keep the body healthy, the condition is known as Vitamin D deficiency. Numerous studies have proved that the deficiency of Vitamin D is one of the causes of sexual dysfunction or specifically, erectile dysfunction. Men who have a low level of Vitamin D are more susceptible to having erectile dysfunction. Erectile dysfunction is a problem with erections, and erections is a complex phenomenon that involves coordination among neurological, vascular, and tissue compartments. Erectile dysfunction can be defined as a condition in which men experiences their incapability to achieve or maintain a satisfactory penile erection. This is one of the most common sexual dysfunction in men, and a large number of men are suffering from this problem.
Numerous studies have suggested that the deficiency of Vitamin D is highly associated with the decreased testosterone level in the human body and testosterone is vital for the functioning throughout the man’s life. Vitamin D plays a role in maintaining the status of testosterone. The development of the condition of erectile dysfunction is related to low testosterone as testosterone is important for the normal erections, due to its impact on the production of nitric oxide. Testosterone controls every component that is involved in erectile function, from sexual desires to smooth muscle relaxation.
Advancing age is not the only factor that causes erectile dysfunction. Instead, there are many factors that affect erectile function. Some of the factors that are known to throw a significant impact on the erectile function are stress, depression, diabetes, obesity, smoking, and drinking. There are some pieces of evidence that directly or indirectly Vitamin D is associated with the factors that cause erectile dysfunction. Depression is one of the most common causes of erectile dysfunction and low-level of Vitamin D is found in people suffering from depression. Reduced level of Vitamin D have been reported in various psychiatric disorders and depression is one of such disorders. Depression is a serious condition that involves symptoms like difficulty in concentrating, lack of confidence and self-esteem, loss of interest in enjoying things, and sadness. It is believed that Vitamin D has many properties that throw a positive impact on mood.
Vitamin D plays an important role in treating many diseases including diabetes mellitus. Diabetes is considered to be one of the major factors that cause erectile dysfunction. Diabetes mellitus is a chronic disease that develops when the blood sugar level of the body becomes too high. It is basically a result of the progressive autoimmune destruction of pancreatic islets. Diabetes mellitus is of two types, type 1 diabetes and type 2 diabetes. Vitamin D has the immunomodulatory effect and this effect points out the role of Vitamin D in decreasing the risk of developing type 1 diabetes. Vitamin D promotes the functioning of the pancreatic cells through direct way and an indirect way. It directly enhances insulin secretion and regulates the effects of cytokines. Vitamin D can also indirectly affect insulin secretion by regulating calbindin. Vitamin D regulates calbindin which is a cytosolic calcium-binding protein. Calbindin modulates the depolarization stimulated insulin release through the regulation of intracellular calcium. Other immune-modulating effects of vitamin D include inhibition of lymphocyte proliferation, development and regulation of cytokine expression. These effects of Vitamin D provides additional protection from the diseases.
