The problem of maintaining an erection

Sexual dysfunction or sexual malfunction is difficulty during any stage of the sexual act (which includes desire, arousal, orgasm, and resolution) that prevents the individual or couple from enjoying sexual activity.

Sexual dysfunction is more common in people who abuse alcohol and drugs. It is also more likely in people suffering from diabetes and degenerative neurological disorders. Ongoing psychological problems, difficulty maintaining relationships or chronic disharmony with the current sexual partner can also interfere with sexual function.

Psychological issues such as depression, anxiety, guilt or fear can sometimes cause sexual problems. At one time, these factors were thought to be the major cause of erectile dysfunction. Doctors now know that physical factors are present in most men with erectile dysfunction. However, embarrassment or "performance anxiety" can make a physical problem worse. Erectile dysfunction caused only by psychological causes is found most commonly in young men.

Men who do not benefit from medical or psychological treatment often have success with mechanical or prosthetic devices. External products, known as vacuum erection devices, are safe and highly effective, but many men and their partners find them unappealing. Another option is a surgically placed penile implant. However, because implants require surgery (with the risk of surgical complications), only 10 percent of men with erectile dysfunction choose this option. Vascular (blood vessel) surgery sometimes is recommended for young, healthy men who develop impotence after trauma to the groin.

Buying medicine via internet

First, it's important to carefully consider the source of information and then to discuss the information you find with your health care professional. These questions and answers can help you determine whether the health information you find on the Internet or receive by e-mail from a Web site is likely to be reliable.

You need keep an up-to-date, written list of ALL of the medicines (prescription and over-the-counter) and dietary supplements, including vitamins and herbals, that you use--even those you only use occasionally.

Health professionals also use computer systems with drug-interaction screening software, electronic prescribing, and other technology. Mark Langdorf, M.D., chair of the department of emergency medicine at the University of California, Irvine, says, "In a busy emergency room, you have to quickly find out what a patient is taking and how those drugs could interact with other treatments."

Premenstrual syndrome

A hot flash is a feeling described as suddenly being hot, flushed and uncomfortable, especially in the face and neck. Hot flashes come in bursts or flushes that usually last a few seconds to a few minutes. They are caused by changes in the way blood vessels relax and contract and are thought to be related to the changes in a woman's estrogen levels.

There is no relation between the time of a woman's first period and her age at menopause. The age at menopause is not influenced by a woman's race, height, number of children or use of oral contraceptives.

Research shows that diet and nutrition play a significant role in the severity of PMS symptoms, and many women could ease their monthly bouts with discomfort simply by changing their diets or taking nutritional supplements.
