Testosterone is a hormone that exists in both sexes, but is predominant in men. Hormones can impact many bodily systems and if you have ever been with a woman suffering from premenstrual syndrome, can see how that can assert itself in mood swings.

Impotence, or erectile dysfunction (ED), has been found to be linked clearly to androgens. These are steroidal hormones of which testosterone is a part and they both stimulate and control the growth of male characteristics. ED is predominantly an affliction of age because of the deterioration of a number of health factors.

As men age, there are a number of diseases and disease risk factors that can come up as a result of androgen depletion. These issues are familiar to anyone going through the aging process including loss of muscle strength and mass, along with issues of bone density. Whether low testosterone causes these issues or these issues cause low testosterone is unknown, but low levels of the hormone have been targeted as a major factor in cardiovascular disease.

When it comes to the penis it is good to know how they work. Erections are not as simple as you might think and involve a number of systems in the body including the neurological, hormonal, vascular, and endocrine. It is the trapping of blood with the vascular rich corpus cavernosum that causes pressure and volume to build in the penis, resulting in an erection.

Men with ED have more than just an issue with their blood flow and maintaining an erection, the structure of the penis can actually change and result in less smooth muscle within the member.

Hypogonadism is a term that applies to men that have low androgen levels and cannot create new hormones within their testicles. Symptoms include a lack of interest in sex, inability to orgasm, and the inability to achieve orgasm.

So for a man with lower testosterone the symptoms of depression, loss of sexual interest, and trouble getting an orgasm are all part of a large syndrome. Concentrations of testosterone that merit diagnosis of clinical ED range between 8 and 12 nmol per liter. Additionally, men with low levels of androgens have metabolic syndromes that can be made worse when a man is overweight or obese.

In fact there have been studies that show obesity, insulin resistance, and testosterone are all interlinked with one another. This was found by looking at the amounts of serum androgens in men with type II diabetes. Clearly, the penis can act as a measure of overall health in a man.

Impotence is not just an inconvenience and can be a symptom of larger issues, or a precursor for other diseases like cardiovascular issues. Being overweight can snowball past hypertension, high cholesterol, diabetic risk, and shows itself through a number of symptoms including impotence. While every man experiences issues with maintaining an erection now and again, if it is consistent, there is a responsible to be seen by a doctor. Clearly there is a relationship between testosterone and impotence.
