Inability to have or maintain an erection

Erectile dysfunction (ED) is one of the most common chronic diseases affecting men and its prevalence increases with aging. ED is defined as the inability of a man to attain and maintain an adequate erection for satisfactory sexual intercourse.

Related causes of ED are variable and can include arterial, neurogenic, hormonal, cavernosal, iatrogenic, and psychogenic causes. It is now widely accepted that ED is predominantly due to underlying vascular causes, particularly atherosclerosis. Some of the physical problems are heart disease, high blood pressure, diabetes, obesity, alcoholism and tobacco use among others.

Erectile dysfunction can then be caused or worsened by stress and mental health problems that can affect bodily systems. Psychological conditions related to erectile dysfunction are depression, stress, fatigue, or relationship problems among others.

Oftentimes, a usually minor physical problem can combine with psychological issues to develop and exacerbate the condition.

Exercise, particularly aerobic exercise during midlife is effective for preventing ED.

Treatment strategies include nonpharmacological and pharmacological procedures:

• Nonpharmacological treatment includes counseling and life style changes.
• Pharmacological treatment of ED includes a number of drug (phosphodiesterase type 5 inhibitors - a group of enzymes), vacuum constriction device, and surgery (penile prosthesis) are other possible therapeutic opportunities.
  

In the late years a number of herbal and nutritional supplements have been used in the treatment of ED such as ginseng.

Hyperprolactinemia in men may result in as a first signs of decreased libido or impotence, however also cause inefficient sperm production and infertility.

Azoospermia

Azoospermia is defined as the complete absence of spermatozoa. Azoospermia is categorized as either obstructive or nonobstructive. Nonobstructive azoospermia refers to a lack of sperm production, whereas obstructive azoospermia implies adequate sperm production but failure to deliver the sperm into the ejaculate because of a ductal obstruction.

Decline in sperm production in the testes may be associated with erectile dysfunction and fertility.
