What is impotence?

There are differences in male sexual function, and men with different physical qualities have different abilities, but this is normal and cannot be generalized. However, some men may have reduced sexual ability due to illness, and impotence is a common problem. It puts men in a very awkward position in sex. Let's take a look at what impotence is.

The occurrence of ED is not only affected by physical diseases such as age, cardiovascular disease, diabetes and hyperlipidemia, as well as psychological and environmental factors such as sexual partner relationships and home conditions, but also by bad living habits, drugs, surgery, race, culture, religion and socioeconomic factors.

What causes impotence?

1. Age

Current research suggests that age is the strongest independent factor among ED-related risk factors. As age increases, the serum androgen level decreases significantly, which may be the direct cause, but there is no research result proving that there is a significant relationship between the decrease in serum free testosterone and ED. In addition, as age increases, the structure of the penis tunica albuginea and corpus cavernosum changes, which may lead to a decrease in venous blood return capacity, an increase in the prevalence of cardiovascular and cerebrovascular diseases, hypertension, diabetes, and the treatment of these diseases, all of which damage the penis' erectile function to varying degrees, and this trend also increases with age.

2. Cardiovascular disease

Cardiovascular disease is the main somatic disease associated with ED, including atherosclerosis, peripheral vascular disease, hypertension and myocardial infarction. Cardiovascular disease causes arterial ED by affecting the arterial blood supply to the corpus cavernosum. Some studies have also found that ED may be the primary manifestation or "warning signal" of cardiovascular disease.

3. Diabetes

Diabetes can affect erectile function by affecting the autonomic nervous system, peripheral vascular system and psychoneural system. The severity and prevalence of ED are significantly related to factors such as age of diabetes, type of diabetes, blood sugar control, diabetic neuropathy, diabetic nephropathy and hypertension.
