Hormones, which are produced out of various sections of the endocrine gland in the body are chemicals in released in the blood. Hormones are essential to enable metabolic reactions and processes in the body and are referred to as “internal Medicine”.
Androgen is the male sexual hormone which majorly consists of testosterone which is the principal male sex hormone apart from androstenedione and dihydrotestosterone. Apart from certain virility functions such as maturing of sex organs and secondary males sexual functions – androgen also has excitation functions that define endocrine erectile behavior.
Hormonal dysfunctions or disturbances in the testosterone levels in the human body can cause sexual dysfunctions in men. Although, the role of androgen (male sexual hormone) in successful erections is not very clearly defined, but it does remain a cause of erectile dysfunction in some patients.
Lack of Androgens in the serum can lead to lack of excitement and sexual libido and the nature of erections. This happens because of the emotional functions that hormones create apart from the physical functions.
Low levels of testosterone in the blood lead to reduction in serum production and decrease in nocturnal erections. Loss of testosterone can be identified by hot flushes and sweating, reduced mass and muscle strength, increased fat in the body- mostly around the abdomen, loss of hair, loss of bone mass and depression.
Testosterone levels usually decline around the age of forty and almost one out of five men is faced with reducing testosterone, thus making it an age related dysfunction but there are a lot of other factors that may lead to fall in the levels apart from ageing such as obesity, lack of a healthy lifestyle etc.
Some testicular medical problems which could be from birth like the Klinefelter’s syndrome or other problems such as undecided testicles, loss of testicles or torsion (losing out of blood supply) or other vascular problems can also lead to hormone reduction. Also, since pituitary gland controls the release of androgens, presence of a benign tumor can inhibit pituitary gland from signalling the body to create testosterone.
Congenital abnormalities too can stop the hypothalamus from signalling the pituitary gland to release hormones. But this happens in very rare cases.
Depleting levels of testosterone levels impact the sexual libido in an adverse manner and may lead to reduced sperm production too.When there is hyponogodism, which means little of no hormone production in the body, testosterone replacement is a remedy that can increase the libido and nocturnal erections.
