Why do men suffer from erectile dysfunction?

Married young and middle-aged men who cannot achieve or maintain an erection sufficient for satisfactory sexual intercourse are diagnosed with erectile dysfunction. Erectile dysfunction caused by anatomical or endocrine abnormalities is called organic erectile dysfunction. Erectile dysfunction caused by medication is called drug-induced erectile dysfunction. So, why do men suffer from erectile dysfunction?

(1) Common factors: Alcohol consumption is probably the culprit among many bad habits that affect sexual function. While excessive alcohol consumption can stimulate a man's sexual desire, it inhibits normal penile erection and ejaculation. Long-term alcohol abuse can damage penile nerves, leading to lifelong, incurable erectile dysfunction.

As men age, the levels of certain male hormones decrease, and the amount of adrenaline in the body declines, further resulting in dehydroepiandrosterone (a male hormone) levels in the body being only half that of a 20-year-old. At age 40, the level of dehydroepiandrosterone (DHEA) in a normal man's body declines even more rapidly. Why does a decrease in DHEA levels lead to erectile dysfunction? First, DHEA is converted into testosterone in the body, and testosterone is a major factor influencing sexual desire in both men and women. Therefore, DHEA has an enhancing effect on sexual function. Second, excessively low DHEA levels in men are inversely proportional to the incidence of heart disease, which in turn greatly increases the likelihood of erectile dysfunction.

Men under high stress are most prone to erectile dysfunction because stress can lead to endocrine disorders and poor circulation, resulting in erectile dysfunction. Conversely, erectile dysfunction can exacerbate stress. Once these two symptoms alternate, a vicious cycle can form, worsening the condition. Therefore, it is important to reduce stress. Once stress is relieved, sexual function will naturally recover.

Men who smoke are more likely to experience erectile dysfunction, possibly due to the arterial spasms caused by smoking.

The pituitary glands in the brain secrete a hormone that stimulates the testes to produce estrogen-2-testosterone. If the pituitary glands are underdeveloped or diseased during puberty, such as in cases of tumors, their secretory function can be impaired, preventing the secretion of sufficient hormones and thus leading to erectile dysfunction.

Mood-regulating medications, such as anti-hyperstimulants, sedatives, stimulants, and sleeping pills, are among the most common causes of erectile dysfunction. In addition, medications used to treat high blood pressure and heart disease, including diuretics, methaqualone preparations, and digitalis, can also cause erectile dysfunction with prolonged use. Furthermore, medications used to treat ulcers may also cause erectile dysfunction.

Heart disease, high blood pressure, and diabetes can cause circulatory disorders, which greatly increases the likelihood of erectile dysfunction. The reason is simple: to maintain a normal erection, blood must flow smoothly to the penis. If there is arteriosclerosis, it becomes extremely difficult for the arteries to deliver blood to the penis, thus preventing an effective erection.

In conclusion, it is easy to determine that several diseases affecting normal erection are related to arteriosclerosis. Therefore, we must pay attention to effectively preventing arteriosclerosis in our daily lives. Furthermore, it should be emphasized that prostate enlargement can directly affect sexual function, leading to impotence.

(2) Long-term cycling can cause impotence: People generally believe that cycling to and from get off work is convenient and good for health. However, urologists remind everyone that long-term cycling can easily cause prostatitis, leading to impotence. Among patients visiting urology clinics, 50% to 60% suffer from prostatitis, and this phenomenon is increasing year by year. The most common cause is long-term cycling.

The prostate is the largest accessory gland in the male reproductive system, located at the bottom of the pelvis, near the perineum. When cycling, the perineum constantly rubs against the bicycle seat, and the seat directly compresses the prostate, easily causing congestion and swelling. Men who cycle for extended periods keep their prostate in a state of congestion, leading to poor local blood flow and ultimately prostatitis. Statistics show that the incidence of erectile dysfunction among professional cyclists is around 40%, and this group also experiences various other sexual dysfunctions.

It's important to note that even in younger patients, untreated prostatitis can lead to benign prostatic hyperplasia (BPH), erectile dysfunction, premature ejaculation, and even infertility. Furthermore, due to the prostate's location, medication often has difficulty reaching it effectively; therefore, prevention of prostatitis is crucial.

The best way to avoid prostatitis caused by cycling is, of course, to ride less. If this is impossible, adjust the bicycle seat height and use a padded seat.

Men who cycle frequently should immediately stop cycling if they experience discomfort in the perineum. Daily warm sitz baths can help improve local blood circulation. If you experience symptoms such as frequent urination or painful urination, you should seek medical attention promptly.

(3) Psychological causes of erectile dysfunction: Generally speaking, about 50% of erectile dysfunction cases are directly caused by psychological factors, and the remaining 50% are also related to psychological factors. It can be said that psychological factors are the most important cause of erectile dysfunction. So, what psychological factors are related to erectile dysfunction?

1) Lack of proper sexual knowledge in adolescents can easily lead to erectile dysfunction: Men in their adolescence may also experience erectile dysfunction due to a lack of sexual knowledge. The reasons are multifaceted. Some parents are overly strict about sex; others experience marital discord; still others, during their children's puberty, not only fail to provide appropriate sex education but also become ashamed to answer their questions about sex. This results in children having misconceptions about sex, mistakenly believing it to be something low-class and vulgar, while viewing normal sexual behaviors like masturbation as morally reprehensible and shameful. This creates a psychological burden, making them afraid to engage in sex. Some individuals, due to negative sexual stimuli such as those promoted by pornography, develop an excessive emphasis on sexual ability, leading to psychological pressure when they feel inferior. All of these situations contribute to the occurrence of erectile dysfunction in adolescents.


2) Marital discord or one partner having other sexual partners can easily lead to erectile dysfunction: During the first sexual intercourse on their wedding night, the newlyweds' unfamiliarity with sexual techniques can lead to failure, causing psychological burden for both parties and affecting the marital relationship. Excessive psychological burden can lead to sexual apathy during intercourse. Furthermore, the wife's infidelity, the husband's hostility towards his wife, or the husband's extramarital affair and lack of interest in his wife are all psychological factors contributing to erectile dysfunction.

3) Lack of self-confidence during intercourse: This refers to some men excessively worrying about their "small penis," fearing they will be unable to satisfy their wives' sexual needs; others overemphasize their responsibility for their wives' sexual satisfaction, believing that even one instance of not satisfying their wives indicates a physical problem; still others have poor psychological resilience and harbor resentment after being blamed by their wives during sex, creating psychological pressure during intercourse. All these factors stem from a lack of self-confidence, leading to erectile dysfunction.

4) Misinterpretations from doctors: Some doctors, either to increase their income or due to limited medical expertise, may describe a patient's "kidney deficiency" as "difficult to treat," causing the patient to constantly worry that their "kidney deficiency" is incurable. This can also lead to erectile dysfunction.

Additionally, some patients, due to other illnesses or concerns about "aftereffects" after recovery from sexually transmitted diseases, may also experience impotence in their sexual life.

The psychological factors listed here are only a part of sexual dysfunction. In real life, specific problems need to be addressed individually, and it is advisable to consult a doctor when necessary.
