Hypersexuality, or eroticism, is a disorder characterized by an overwhelming desire for sexual activity and the ability to have sexual intercourse too often and to complete the entire process. Its incidence is not low, and it can be seen in both men and women. This disease not only affects their own health, and can be a scourge to sexual partners, should not be ignored. Modern medicine believes that the common causes of its development are: excessive secretion of gonadotropins or sex hormones in the anterior pituitary gland; excessive activity of the hypothetical libido center in the hypothalamus; dysfunctional libido inhibition activity in some psychiatric patients. Treatment advocates the application of sedatives and hormone therapy. The records of this disease in Chinese medical literature and the reports in various medical journals are rare. The main clinical manifestations of this disease are too frequent, too fast, too dramatic sexual intercourse, or even sexual excitement and restlessness when meeting sex. In Chinese medical literature, this disease is included in the category of Yangqiang disease (modern male science has distinguished this disease from Yangqiang, Yangqiang is comparable to the abnormal erection of the penis in Western medicine), the cause of the disease is mostly due to excessive thinking of prostitution to phase fire delusion or yin deficiency fire, in short, mainly related to “fire”, the key to the pathogenesis of liver stagnation and fire and yin deficiency fire 2. In modern medicine, the mechanism of hypersexuality is the enhancement of the sexual central excitement process. Most of them are caused by psychological disorders, or doubts arising from insufficient knowledge of sex. A few are organic lesions caused by pathological changes, or lesions caused by pharmacological factors. A, mental factors by the influence of some sexual culture, especially pornographic novels, pornographic videos and other excessive stimulation, resulting in sexual psychological disorders, long-term in a state of hyperactivity. Second, organic factors neuroendocrine disorders, such as pituitary tumors, testicular mesenchymal cell tumors, intracranial tumors, etc., the pituitary gonadotropin or androgen overproduction, lack of inhibition. The brain and hypothalamus have enhanced sensibility to sex hormones, and cause hypersexuality. Some mental diseases can cause the brain to lose control of its ability to be sexually excited thus manifesting as excessive sexual impulses. The attack of chronic diseases such as tuberculosis, resulting in sexual central nervous function disorder, patients can show different degrees of hypersexuality. The use of gonadotropin drugs or testosterone drugs, as well as superstition, taking certain “aphrodisiac” drugs, “aphrodisiac” can lead to hypersexuality. It has been reported that amphetamines can cause hypersexuality. In addition, drug addiction may also induce hypersexuality.
