Obesity is associated with a high prevalence of erectile dysfunction; how-ever, the pathophysiological link between obesity and erectile dysfunction
remains poorly understood. In this minireview, we have attempted to eval-uate the existing literature pertaining to obesity and erectile dysfunction to
determine whether a common pathophysiological link exists.
Approach to the Patient: Erectile Dysfunction
A good physician-patient relationship helps to unravel the possible causes of ED, many of which require discussion of personal and sometimes embarrassing topics. For this reason, a primary care provider is often ideally suited to initiate the evaluation. A complete medical and sexual history should be taken in an effort to assess whether the cause of ED is organic, psychogenic, or multifactorial (Fig. 492). Initial questions should focus on the onset of symptoms, the presence and duration of partial erections, and the progression of ED.
The area of treatment of sexual disorders has undergone an enormous expansion
during the last few decades. The introduction of pharmacological treatment of
these disorders (e.g., sildenafil for erectile dysfunction or antidepressants for
paraphilias) rekindled the interest of physicians from different disciplines
(psychiatrists, urologists, gynecologists) in sexual dysfunctions. Physicians are
finding these disorders amenable to pharmacotherapy
Disorders that affect the sacral spinal cord or the autonomic fibers to the penis preclude nervous system relaxation of penile smooth muscle, thus leading to ED. In patients with spinal cord injury, the degree of ED depends on the completeness and level of the lesion. Patients with incomplete lesions or injuries to the upper part of the spinal cord are more likely to retain erectile capabilities than those with complete lesions or injuries to the lower part.
The modern era in sexual medicine started in the
1970s when a few devoted pioneers and visionaries
began to revolutionize our thinking and understanding
in this field.
Prior to that time, sexual dysfunctions in men,
particularly erectile disorders, were thought to be
purely psychogenic or in rare cases caused by testosterone
deficiency. Treatment of sexual disorders was
considered to be predominantly the business of sextherapists
or rarely of endocrinologists.
Normal functioning of reproductive systems of male
and female, no doubt is expected of all individuals.
But one of the vagaries of nature is aberration of this
function. While fertility is an essential ingredient for
survival and continuity of species, not all couples are
capable of furthering their families. So the problem
of infertility finds its place in the recorded history of
ancient civilisations of Babylonia, Persia and Greece.1
Goddesses of fertility, fertility rites, and superstitions
encompassing the process of birth are mentioned in
the history of these civilisations.
Inflammation can also be found in the intervertebral disks resulting in discitis and
spondylitis, which can be seen as narrowing of the intervertebral space and destruction of
the adjacent cover plates. Seldom synovitis and osteitis can be found in the atlantoaxial area
leading to erosions and destruction of the lateral atlantoaxial joint. At the worst the joint is
destabilized, this may cause cord compression and neurological loss of function.

Rối loạn cương dương (ED: Erectile Dysfunction) Rối loạn cương dương (RLCD) hay còn gọi là bất lực, là một tình trạng rối loạn với biểu hiện dương vật không thể cương cứng hay không duy trì được sự cương cứng trong quá trình giao hợp.
Moreover it is important to be able to restrict this invasive
investigation to men who are likely to benefit from treatment of this malignancy. There are
currently concerns that Western clinicians and healthcare providers are over-diagnosing large
numbers of men who would otherwise never have been troubled by their clinically
undetectable prostate cancer.
Being a man should not seriously damage your health, conclude White and Banks
(2004) in their chapter in a men’s health text. The maxim is used at the beginning of
this text to remind the practice nurse of the fact that being a man in some instances
can and does seriously damage their health. Men are much less likely to visit their
general practice than women. Those men who are aged under 45 years visit their
general practice only half as often as women; it is only when they become older that
the gap narrows signifi cantly....
The prostate gland is actually not a single gland. It is
comprised of a collection of glands that are covered by a
capsule. A gland is a structure or organ that produces a
substance used in another part of the body. The prostate
gland lies below the bladder, encircles the urethra, and
lies in front of the rectum. Because it lies just in front of
the rectum, the posterior aspect of the prostate can be
assessed during a rectal examination. The normal size of
the prostate gland is about the size of a walnut (Figures 1
The nature and treatment of radiation-induced injury to the gastrointestinal tract should be
included in the training programmes for oncologists and gastroenterologists.
Prior to treatment, men and their partners should be warned that treatment for prostate cancer
will result in an alteration of sexual experience, and may result in loss of sexual function.
Men and their partners should be warned about the potential loss of ejaculation and fertility
associated with treatment for prostate cancer. Sperm storage should be offered.
