The endocrine system is considered to be a control system of the ductless glands that produce hormones within the organs. This system provides an electrochemical connection from the hypothalamus which is the part of the brain to all the organs of the human body that controls the metabolism, growth, development, and reproduction. The collection of endocrine glands makes up the endocrine system and endocrine glands are the glands which have no ducts and release their secretions into the blood. The main endocrine gland includes pituitary, thyroid, parathyroid, adrenal, pancreas, and gonad. The nervous system and the endocrine tissues keeps a record on the internal conditions of the body and if required to maintain homeostasis, hormones are released by an endocrine system. Various endocrine disorders can cause erectile dysfunction or other sexual dysfunctions such as diabetes, hypogonadism, thyroid disorders, hyperprolactinemia, obesity and adrenal disease.

 Role Of The Endocrine System In Erectile Function

Erectile dysfunction is defined as a persistent inability in getting or maintaining erections until the complete sexual activity. It is a prevalent problem among men these days and now, various medicines and natural ways are available to treat this sexual dysfunction, such as Cialis and Viagra. Normal sexual functioning involves sexual desires, erections, ejaculation, and detumescence and erection is a complex, involuntary, neuropsychological, and a hormone mediated event. The hypothalamic-pituitary-testis axis is the most important endocrine system that affects the functioning of the male sexual system. Endocrine abnormalities increases with an advancing age and development of problems related to erections also increase with an advancing age. Numerous studies have suggested a link between endocrine factors and erectile dysfunction, for example, erectile dysfunction is caused by prolactinoma as an improvement in the erections were noticed with the treatment of hyperprolactinemia. Also, the importance of androgens is at a high level as they serve an important role in penile erection, endothelial function, and smooth muscle cells.

When we talk about male sexual health, testosterone is the most involved hormone. In addition to its responsibility for the development of male sexual organs and other secondary characteristics, testosterone also regulates the sexual desires. Testosterone plays a complex role in the male sexual function and the production of testosterone is highly associated with libido and the mechanism of penile erection. Libido is a term which includes spontaneous sexual thoughts and fantasies, attentiveness, arousal response to sexual stimuli, and responsiveness to erotic stimuli. There is no doubt in saying that deficiency of testosterone in the males is responsible for the development of erectile dysfunction. The deficiency of testosterone often leads to the development of disease known as hypogonadism and disruption in the levels of the hypothalamic pituitary gonadal axis is the main cause of this disorder as the hypothalamic pituitary gonadal axis is that part of the human body that controls the production of testosterone in the human body.

Fluctuations in the level of prolactin hormone are also liked to the development of sexual dysfunctions and when a person has higher than the normal level of the hormone prolactin in the bloodstream, it is known as hyperprolactinemia. Hyperprolactinemia can be caused by various factors ranging from psychological to pathological factors. In men, this disorder is often associated with hypoactive sexual desire disorder and this is because prolactin has a direct effect on the sexual desires. Hypoactive sexual desire disorder is a complex sexual disorder which is defined as a lack or absence of sexual desires or fantasies for the sexual activity. In males, the decrease in the nocturnal erections is observed in the people who suffer from hypoactive sexual desire.

A large number of studies have researched on the relationship between thyroid disorders and sexual dysfunction. Studies revealed that there is a relationship between thyroid disorders and low sex drive and low sex drive is a most common symptom of underlying diseases including sexual dysfunctions. In the human body, the thyroid gland is an endocrine gland that is located in the neck and produces two important hormones in the body, thyroxine and triiodothyronine. Hyperthyroidism is a condition which occurs when the secretion of hormones by the thyroid gland becomes excessive. Whereas, Hypothyroidism is a condition which occurs when the thyroid gland does not produce an adequate amount of thyroid hormones. Numerous studies have suggested that directly or indirectly, thyroid disorders cause problems in the erectile function and men who have thyroid disorder often experience unsatisfactory sexual activity.
