Analysis of Erectile Dysfunction and its Influence by Psychological Factors

Why is my penis normally erect but unable to achieve an erection during intercourse?

Some young men have normal erectile and ejaculatory functions before marriage. However, after marriage, although they can still achieve an erection, especially upon waking at night or in the morning when their bladder is full, the erection quickly becomes flaccid during intercourse, making it impossible to have sex. This casts a shadow over their marital life and can even lead to discord or family tragedy.

This phenomenon is quite common in andrology clinics and is medically termed psychogenic erectile dysfunction. To explain this, we need to understand the principle of penile erection. Penile erection can be achieved through two pathways: one is psychogenic erection, where erection occurs through visual, auditory, olfactory, and tactile stimuli that trigger thoughts in the brain. These are not directly related to the genitals, but rather the brain sends commands through the psychogenic erection center in the thoracolumbar spine, which then transmits these commands to the autonomic nervous system, causing the penis to become engorged and erect. Another type is reflex erection, which occurs when stimulation received by the glans penis is transmitted via nerves to the reflex erection center located in the sacral spinal cord, and then the penis erects through the autonomic nervous system. In a normal erectile response, these two different pathways complement each other, resulting in an erection. The latter is more effective, but the former also plays a significant role.

From the perspective of erectile dysfunction, some cases are caused by disorders of the vascular nerves responsible for erection, endocrine imbalances, systemic diseases, or the use of certain medications that inhibit erectile function. Others experience erectile dysfunction due to emotional factors, such as fear or anxiety about sexual activity, worry or doubt about whether penis size will affect their partner's sexual satisfaction, or excessive physical fatigue, high mood, family misfortunes, or marital discord. The former is called organic erectile dysfunction, and the latter is called psychogenic erectile dysfunction. Therefore, while the brain's thinking can promote sexual arousal and erection, it can also have the opposite effect, inhibiting sexual function and causing erectile dysfunction.

Because the treatments for organic and psychogenic erectile dysfunction are completely different, it is essential to differentiate between these two types of erectile dysfunction before treatment. The presence or absence of nocturnal erections is the most effective "litmus test" for differentiation. During sleep, the cerebral cortex enters an inhibited state, completely losing control over the lower centers. Psychogenic factors in erectile dysfunction cannot play a role, allowing the lower centers to receive even the slightest stimulus and induce penile erection. Therefore, the presence of nocturnal erections indicates that erectile function is normal; the inability to achieve an erection is due to psychological inhibition, and should not be considered a problem with the reproductive organs. Treatment should first identify and eliminate the cause of psychological inhibition. Usually, after psychological counseling by a doctor to relieve anxieties, the problem can be resolved. Some people believe that a childhood habit of masturbation inevitably affects their sexual function, leading to constant anxiety and fear of failure. This psychological state can cause psychogenic erectile dysfunction. After a doctor's analysis and explanation, they understand that masturbation does not directly cause erectile dysfunction, relieving their anxieties and restoring confidence in their sexual function. Thus, normal erections can be restored without medication. However, some individuals, due to prolonged periods of unsuccessful intercourse, have developed further anxiety and created a negative conditioned reflex, experiencing erectile dysfunction simply by thinking about intercourse. In such cases, medication and sensate focus training under a doctor's guidance are necessary to resolve the issue.

Fatigue and Erectile Dysfunction

Penile erection is highly susceptible to psychological factors. Fatigue is only an indirect cause. Please see the answer to this question in 《Popular Health》 magazine.

"Does fatigue cause erectile dysfunction?" The answer is not difficult, because when a person feels tired, that is precisely when they need rest. From a physiological perspective, at this time, the nervous system and various organs need "rest" and are in a state of inhibition. From a psychological perspective, this is a stage where a person is indifferent to the external environment or certain stimuli, or rather, uninterested. In short, due to fatigue or after being subjected to some strong stimulus, both physical strength and energy are in a "low tide." How can sexual intercourse be possible in this state?

The process of sexual intercourse is the result of a combination of factors. First, there must be sexual desire. This "desire" is a desire that arises under certain stimulation or when interacting with the opposite sex. Moreover, this desire can only occur when a person's mental, psychological, and physical condition is good, and the brain is in a state of sexual arousal. Studies have shown that during sexual intercourse, a person's emotions are excited, heart rate increases, breathing becomes rapid, and blood pressure also rises. When the penis is erect, the blood flow can reach 80-200 ml, with increased local congestion. At this time, the energy consumed by a person in 10 minutes is equivalent to the energy consumed by the height of a 4-5 story building. After strenuous activity, a large amount of metabolic waste accumulates in the body, requiring time to eliminate and restore energy. If one were to expend energy again or re-excite the cerebral cortex at this time, most people would find it difficult to achieve erectile dysfunction.

Penile erection is highly susceptible to the influence of mental and psychological states. Therefore, when a person feels tired, unhappy, has something on their mind, or is in a state of mental and psychological imbalance such as fear, anxiety, or irritability, temporary erectile dysfunction may occur. However, this type of erectile dysfunction is not a disease. Don't overemphasize or let life's setbacks or difficulties in your sex life become a mental burden that leads to erectile dysfunction. When this erectile dysfunction occurs, don't panic. Simply adjust your mental and psychological state and prepare your physical strength; it can be completely eliminated.
