Hydrotubation is to use methylene blue solution or saline through the cervix to the uterine cavity, and then from the uterine cavity into the fallopian tube, based on the size of the opposition and also liquid reflux when injecting a liquid, to find out if the fallopian tube is definitely blocked.

Although hydrotubation has a certain effect on treating tubal obstruction, the volume and surface part of the uterine cavity is significantly larger than the cross-sectional area of the tube and tubal cavity, hence the pressure of injecting fluid into the fallopian tube is incredibly restricted. The severity of fallopian tube obstruction can not be clearly defined by the liquid moving from the fallopian tube. There is no injected liquid in the process of hydrotubation is visible, hence the location and severity of tubal blockage can not be determined.

Hydrotubation can just cure some obstruction of the fallopian tubes in construction, but can not get rid of the unnatural function of muscle peristalsis and cilia swing. A lot of conditions just like endometriosis, pelvic inflammation diseases, tubal pregnancy surgical procedures will lead to an unusual function of fallopian tube muscle peristalsis and cilia swing, impacting on being pregnant.

In addition, before hydrotubation, the doctor does not know whether the patient has got vaginitis, endometritis, etc. or not, so 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.

Besides regular fallopian tubes, being pregnant also requires the following conditions:

1. Ovary expels normal eggs.

2. Normal semen with normal sperm

3. Ovum and semen can match in the fallopian tube and become fertilized ovum.

4. Fertilized ovum are generally smoothly transported to 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.

Being pregnant can be a complex physical process. The probability of normal conception is about 20%-25% every 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 other health conditions impacting on women 's pregnancy are actually identified, including pelvic inflammation, endometriosis, etc, they must be treated actively.
