Why does a penis get an erection?

The male penis will grow longer and longer as he gets older. The growth of the male penis will not stop until puberty. However, adolescent males will face an important problem, that is, the penis will often become erect. Although penis erection is an important manifestation of physical desire in men, why does the male penis become erect after physical desire?

Why does a man's penis get erect?

Penile erection depends on the coordination and cooperation of four links: sound neural reflex pathways, normal endocrine function, sufficient arterial blood infusion and effective blocking of venous blood outflow, and normal penile anatomical structure. No link can be missing or wrong.

Generally speaking, a person's first physiological erection occurs when he is 5 to 6 years old or younger in childhood, and this situation has nothing to do with sexual experience. Later, erections will become more frequent, and when sexual maturity occurs, erections will become a manifestation of sexual desire for the opposite sex. Men have the strongest erection ability around the age of 20, and then the erection ability gradually weakens. The time when the erection disappears is different for everyone. Some people can maintain it until the age of 90, while others will be "powerless" at the age of 40.

What factors affect men's penis erection?

1. Alcoholism and drugs

Large doses of alcohol can cause fatal damage to men's erectile function. At the same time, drugs, especially anesthetics such as cocaine and amphetamine, can enhance sexual ability in the short term, but after a few uses, they can "disable" a person's erectile function. Other diseases that reduce erectile function include diabetes, certain endocrine diseases, prostatitis, and arteriosclerosis, especially arteriosclerosis of the reproductive organs. In addition, if male hormones are abused without medical guidance, resulting in excessive levels of male hormones in the body, male erectile function can also be damaged. Obviously, long-term depression, psychological stress, anxiety and other adverse psychological conditions can also weaken erectile function.

2. Sexual language and sexual actions

For young men, although erections were common in the past, they often have difficulty getting an erection when they have sex for the first time because of excessive excitement. The more anxious some young men are, the more trouble they will encounter in their sex life. In this case, the woman's words and actions will play a vital role. It should be noted that if they are not careful at this time, they will hurt the man's self-esteem, which will affect their erectile function. However, if a man "try and try again and again" in multiple sexual lives, then you should think about whether he really suffers from erectile dysfunction. For middle-aged and elderly men over 40 years old, the words and actions of their lovers in sex life have an increasingly important impact on their erectile function.

3. Frequent sex life

Any deviation from normal sexual behavior, whether it is too frequent or too infrequent sex, will have a negative impact on a man's erectile ability. It is well known that long-term "abstinence" for any reason - a break in sexual life for more than a few weeks - will lead to a weakened erection. In ancient times, many merchants and sailors went out for many days without having sex, which greatly increased the chance of professional impotence. On the other hand, some people have sex more than seven or eight times a week, which will also weaken their erections.

4. Sex hormones

There is no direct link between fertility and erectile function. For men, the level of sex hormones in the body reaches its peak when they are close to 30 years old, but at this time, sexual function begins to decline, although erections are often not a problem. Men's fertility can be maintained for a long time. Of course, if infertility is related to insufficient sex hormones, then insufficient sex hormones will also reduce erectile function.

5. Moderate exercise

Moderate physical activity, such as physical labor and sports, can improve sexual ability, including erectile ability, while excessive physical load will weaken erection. At this time, excessive physical load not only causes fatigue, but also excessive muscle growth will "take away" a lot of sex hormones, which will reduce sexual ability. Therefore, those who are overly obsessed with high-intensity sports should understand this.
