First, obesity is prone to diabetes, hypertension, cardiovascular and cerebrovascular diseases. Obese people generally have dyslipidemia, hypercholesterolemia and hypertriglyceridemia, and these diseases themselves will cause metabolic disorders in the body. There is a small amount of estrogen in normal men. Most of these estrogens are converted from androgens, and a few are directly secreted by seminal vesicles.
Second, the increase of fat in obese people makes androgen more converted into estrogen. There is a small amount of estrogen in normal men. Most of these estrogens are converted from androgens, and a few are directly secreted by seminal vesicles. Although there is little estrogen in blood, it plays an important role in regulating gonadotropin secretion by pituitary and testosterone secretion by testis. With the increase of fat in obese people, more androgens are converted into estrogens, and the blood drug concentration can be increased by about 1 fold, so androgens will decrease relatively or absolutely, which is manifested as decreased sexual desire, weakened or lost erectile function and disordered ejaculation function.
Third, the mental stress caused by overweight. Sexual difficulties caused by obesity can also cause problems in image and self-confidence, so mental factors are also a cause of impotence caused by obesity. Generally, obesity will not have a significant impact on sexual function, but if it is overweight and difficult, there will be problems in image and self-confidence. Therefore, mental factors are also a cause of impotence caused by obesity.
Generally speaking, there are some explanations about whether obesity can lead to impotence. Obesity can lead to impotence, but not all obese men will be impotent.
