Constipation of varying degrees of severity is present in many of the women who visit the doctor for dysmenorrhea, vaginal cramps, and frigidity; the same is true of men who suffer from painful ejaculation, premature ejaculation, and failure to ejaculate. Interestingly, when chronic constipation reduces or disappears, the obstacles related to sexual life also reduces or disappears. It is believed that there is a link between chronic constipation and sexual dysfunction. Because chronic constipation not only makes the rectum long-term involvement, resulting in unstable anal pressure, perianal contraction too tight, but also affects the function of the bladder, uterus and other pelvic tissues and organs. Pelvic muscle groups suffer from chronic constipation stimulation, the anus muscle, perineum deep transverse muscle, urethrovaginal sphincter and so on can appear spasmodic state. Over time, these muscle groups will appear malnutrition and excessive relaxation. And these muscle groups and penile erection, ejaculation and vaginal function have a very close relationship. Especially the pubococcygeus, some people call it “sex muscle”, it is a broad ligament, such as a taut hammock to support the pelvic organs and vaginal muscles. If the pubic caudal muscle is often in a state of relaxation or abnormal tension, it will make the vagina sensitivity decreased, sexual pleasure weakened. Sometimes it can also cause urinary incontinence. Therefore, when suffering from decreased libido and sexual dysfunction, you may want to pay attention to see if you have chronic constipation. Normally, we should develop the habit of eating more fresh fruits and vegetables and having regular bowel movements to prevent chronic constipation.
