Hydrotubation is to apply methylene blue option or saline from your cervix into the uterine cavity, and next from the uterine cavity into the fallopian tube, according to the size of the opposition and liquid reflux when inserting a liquid, to determine whether or not the fallopian tube is definitely obstructed. Although the hydrotubation has a specific impact on the treatment of tubal obstruction, the volume and surface area of the uterine cavity is really a lot bigger than the cross-sectional section of the tube and tubal cavity, therefore the pressure of injecting fluid into the fallopian tube is incredibly restricted. The severity of fallopian tube blockage can not be clearly defined by the liquid moving via the fallopian tube. There is absolutely no injected liquid during this process of hydrotubation can be seen, therefore the place and harshness of tubal blockage can not be determined. Hydrotubation is only able to deal with some blockage of the fallopian tubes in structure, but may not solve the abnormal function of muscle peristalsis and cilia swing. Many diseases for example endometriosis, pelvic inflammation diseases, tubal pregnancy surgical treatments will cause the irregular function of fallopian tube muscle peristalsis and cilia to swing, affecting pregnancy. Additionally, before hydrotubation, your doctor will not find out if the patient has got vaginitis, endometritis, etc. or not, consequently it provides great loss of sight. The patients with these diseases are likely to bring pathogenic bacteria (such as mycete, trichomonas, mycoplasma, chlamydia, etc.) into the uterine cavity, fallopian tube, and abdominal cavity during the procedure, resulting in adverse consequences. For example, chlamydia can produce toxins that cause blockages in the genital tract and induce infertility. In addition to regular fallopian tubes, pregnancy also needs the following conditions: 1. Ovary expels normal eggs. 2. Standard semen with normal sperm 3. Eggs and semen can match within the fallopian tube and become fertilized ovum. 4. Fertilized eggs are generally smoothly carried into the uterus 5. The endometrium has been fully ready for fertilized egg implantation. Any abnormality in these links can hinder conception. The reasons for obstructing conception may be the woman, the man or both. Having a baby is actually a complex physiological process. The possibilities of normal getting pregnant are roughly 20%-25% each month. It is normal that there is no pregnancy in several months after hydrotubation. If women are not pregnant for more than one year, the husband and wife should go to the hospital together for the examination. If some other disorders impacting on women 's being pregnant are actually detected, just like pelvic PID, endometriosis and so on, they must be treated actively.
