Sexual problems in men
Fortunately, most sexual problems are treatable, so it is important to share your concerns with your partner and doctor.

What causes sexual problems?
Sexual dysfunction can be a result of a physical or psychological problem.

Physical causes: Many physical and/or medical conditions can cause problems with sexual function. These conditions include diabetes, heart and vascular ( blood vessel) disease, neurological disorders, hormonal imbalances, chronic diseases such as kidney or liver failure, and alcoholism and drug abuse. In addition, the side effects of certain medicines, including some antidepressant medication, can affect sexual desire and function.

Psychological causes: These include work-related stress and anxiety, concern about sexual performance, marital or relationship problems, depression, feelings of guilt, and the effects of a past sexual trauma.
Who is affected by sexual problems?

Both men and women are affected by sexual problems. Sexual problems occur in adults of all ages. Among those commonly affected are those in the older population, which may be related to a decline in health associated with ageing.

How do sexual problems affect men?
The most common sexual problems in men are ejaculation disorders, erectile dysfunction, and inhibited sexual desire.

What are ejaculation disorders?
There are different types of ejaculation disorders, including:

Premature ejaculation -- This refers to ejaculation that occurs before or soon after penetration.
Inhibited or retarded ejaculation -- This is when ejaculation is slow to occur.

Retrograde ejaculation -- This occurs when, at orgasm, the ejaculate is forced back into the bladder rather than through the urethra and out the end of the penis.

In some cases, premature and inhibited ejaculation are caused by a lack of attraction for a partner, past traumatic events and psychological factors, including a strict religious background that causes the person to view sex as sinful. Premature ejaculation is often is due to nervousness over how well a man will perform during sex. Certain medications, including some anti-depressants, may affect ejaculation, as can nerve damage to the spinal cord.

Retrograde ejaculation is common in males with diabetes who suffer from diabetic neuropathy (nerve damage). This is due to problems with the nerves in the bladder and the bladder neck that allow the ejaculate to flow backwards and into the bladder. In other men, retrograde ejaculation occurs after operations on the bladder neck or prostate, or after certain abdominal operations. In addition, certain medicines, particularly those used to treat mood disorders, may cause problems with ejaculation. This does not generally require treatment unless it impairs fertility

What is erectile dysfunction?
Also known as impotence, erectile dysfunction is defined as the inability to attain and/or maintain an erection suitable for intercourse. Causes of erectile dysfunction include diseases affecting blood flow, such as atherosclerosis (narrowing of the arteries); nerve disorders; psychological factors, such as stress, depression, and performance anxiety (nervousness over his ability to sexually perform); and injury to the penis. Chronic illness, certain medications, and a condition called Peyronie's disease (scar tissue in the penis) can also cause erectile dysfunction.

What is inhibited sexual desire?
Inhibited desire, or loss of libido, refers to a decrease in desire for, or interest in sexual activity. Reduced libido can result from physical or psychological factors. It has been associated with low levels of the hormone testosterone. It also may be caused by psychological problems, such as anxiety and depression; medical illnesses, such as diabetes and high blood pressure; certain medications, including some anti-depressants; and relationship difficulties
