      Mr. Ma has just passed his forties and is at a time when he is full of energy and has a successful career. Due to his outstanding achievements in teaching and scientific research, he was promoted to professor and doctoral supervisor. His wife worked in a bank, and his only daughter was studying in a key middle school in the city. Everything seemed perfect. However, it is regrettable that he lacks a harmonious and happy sex life. As soon as his external genitalia touches his wife's vagina, semen overflows - this is obviously Premature ejaculation . For this reason, he was always complained by his wife, and he himself felt very frustrated. After questioning and examination, the doctor found out that he was devoted to his work, rarely moved around, loved to eat chili peppers, had a bowel movement every three or four days with great effort, and had suffered from hemorrhoids for many years. After ruling out other diseases, the doctor believed that his premature ejaculation was related to chronic constipate related. Later, he followed the doctor's advice and insisted on exercise Body: Eat fresh vegetables and fruits regularly, especially vegetables rich in crude fiber, and gradually have a bowel movement once a day. After a period of time, premature ejaculation will be cured without treatment.

      Ms. B works as a senior engineer in a research institute. She has a well-proportioned figure, cloud-like hair, and a pair of charming dimples on her fair and rosy face. At first glance, she does not look like someone over forty. But she also has her own confusion, that is, she is not interested in sex life. People say that "a woman is as fierce as a tiger in her forties", but let alone take the initiative, even having sex once every half month is a hasty affair, even though her husband is gentle and flirty and remains indifferent. At her husband's urging, she came to the sexual medicine clinic for consultation. The doctor learned that she was devoted to scientific research and ate very refined foods. She usually had a bowel movement only once every three to five days or even once a week and it was quite difficult. They thought her frigidity was caused by chronic constipation. After adjusting her diet and taking some laxatives, her constipation was gradually corrected, and her "sexual" interest continued to increase.

      Why does constipation affect sexual desire? To understand this problem, we have to start with the ins and outs of defecation. It turns out that there is a "defecation center" in the sacral spinal cord. When feces enters the rectum, the stimulation is generated along the pelvic cavity. nerve It is transmitted to the defecation center and then sent out by the parasympathetic fibers of the pelvic nerve, causing rectal contraction and anal sphincter relaxation, which is the spinal reflex of defecation. In adults, the defecation reflex is carried out under the control of the cerebral cortex. At this time, the diaphragm and respiratory muscles of the abdominal wall also contract strongly at the same time, the glottis closes, the abdominal pressure increases, the levator ani muscles contract, and feces comes out. However, if the "circumstances" do not allow it, the cerebral cortex will inhibit the activity of the defecation center, increase the tone of the anal sphincter, reduce the tone of the colon, and the "meaning to defecate" will disappear. For people with chronic constipation, it is this reflex arc that is "faulty" and the "instructions" issued by the defecation center are not very effective. This not only affects the rectum, but also causes adverse stimulation of the pelvic muscles, and the perineum, urethra, and vaginal sphincter will be in a state of spasm. Over time, these muscle groups will experience relatively insufficient blood supply and excessive relaxation. And these muscle groups are related to penis erection, ejaculation The normal functioning of the vagina and vagina are also controlled by the pudendal nerve, resulting in male prone to premature ejaculation, no ejaculation, no orgasm, female then there is Pain during intercourse , vaginismus, frigidity, etc.

      Women who have had sexual life experience will find that when they reach orgasm, in addition to the slight twitching of the vagina, there will also be bursts of contraction around the anus. This is the result of the work of the pubic and coccygeal bones. The pubococcygeus muscle attaches to the pubic bone and coccyx. Like a tight hammock, it supports all the organs in the pelvis and the vaginal muscles, participates in the contraction of the lower large intestine and vagina, and improves the defecation movement and the vagina's "clenching" effect on the penis. When two sexes have intercourse, the pubococcygeus muscles are excited and the vagina contracts, compressing and clenching the penis, making the couple's life happier, more satisfying, and more harmonious. If a woman suffers from chronic constipation, the pubococcygeus muscles will be in an abnormally tense state. Over time, the sensitivity of the vagina will decrease, the sex appeal will weaken, and even sexual frigidity will occur. Therefore, when your sexual desire decreases or you have premature ejaculation, Impotence , frigidity, etc. sexual dysfunction When this happens, you might as well pay attention to rule out whether it is caused by constipation.

      For people with chronic constipation without organic disease, they should pay attention to adjusting their diet structure, drinking more water, and eating more foods rich in crude fiber. If necessary, they can also take appropriate amounts of Chinese and Western medicines such as Maren Pills and Fecesitin. Facts have proved that in order to maintain sexual youthfulness, preventing and treating chronic constipation is an important part.
