Problem 1. Fallacy – it is not easy to get pregnant with a posterior uterus. In our clinical work, we often come across patients who believe that they have a posterior uterus, so it is not easy for them to get pregnant, and even some doctors think so too. However, the correct view is: no matter whether the uterus is positioned anteriorly, centrally, or posteriorly, the cervix is in the vagina. After sex, the vagina remains closed, semen exists in the vaginal vault, half an hour to an hour after liquefaction, sperm began to swim, relying on the sperm tail of the clockwise swing straight ahead, the external collision force forced it to change direction. Whether the sperm can successfully enter the fallopian tube and meet the egg has nothing to do with the position of the uterus. Question 2: From a fertility point of view, does celiac disease need to be treated? What kind of treatment should be used? From the fertility point of view alone, if the secretion is not much, it will not affect the sperms to penetrate into the uterine cavity; however, if the secretion is sticky and in large amount, the relatively weak sperms will be blocked by the cervical mucus, which is the first natural barrier. Treatment for it can be varied in primary care hospitals. Some doctors believe that celiac disease belongs to chronic cervicitis, so they use antibiotic infusion treatment, which is really nonsense! Cervical erosion is pseudo erosion, the columnar epithelium located in the cervical canal occupies the squamous epithelium on the surface of the cervix, it is a histomorphologic change, not the usual pus, infection or ulcer. The correct treatment is that mild celiac disease can be treated with medicated cervical topicals that have cauterizing properties; moderate to severe celiac disease can be treated with physical therapy such as lasers or microwaves, which can be effective. However, the ensuing concern is whether these physical therapies will cause cervical dystocia during labor? The answer is: no. This is because unlike the freezing or electric or fire branding of earlier years (which could not properly control the depth), the depth of laser or microwave is about 0.4mm, which does not cause cervical scarring and does not increase the probability of cervical refractory labor. Question 3: Semen examination is a common clinical problem. The sperm count examined requires that more than 200 or more sperm be analyzed to get a statistical result, while some semen reports analyze only a few dozen sperm to arrive at the sperm viability, which is inaccurate. The effect of abstinence time on the results. It is usually better to go for a test after 3-5 days of no sperm discharge. Prolonged periods of no sperm discharge or continuous sperm discharge can have an effect on sperm count and viability. Semen results are very volatile and are affected by many factors, such as stress, fatigue, illness, night train ride, etc., which may cause abnormal semen, so sometimes it is necessary to check the semen 2-3 times. Q4. What is tubal intervention? Tubal intervention is a method of examination and treatment. However, the results are limited. It is useful for treating interstitial blockage secondary to cellular debris and tubal spasm. If the lumen of the fallopian tube is completely blocked, even if it is a small section, and a tunnel is drilled with a guide wire, the normal anatomy of this section of the lumen cannot be restored, and the longitudinal folds of the mucosal layer are scarred, and the epithelial cells of its surface are destroyed, especially the ciliated cells, which have a great impact on the transport of eggs or gametes. If the distal fallopian tube is hydrated, a guide wire is inserted and a tiny hole is opened, which is clear at the time and soon adheres to the hydrosalpinx again. Question 5. Common methods of tubal examination and new advances. Each method of examination has its own advantages and disadvantages. Fluid passage: convenient, simple and inexpensive. If there is no resistance and no large amount of fluid reflux, or if ultrasound reveals the presence of fluid in the pelvis, it can diagnose that at least one side of the tubes is patent, but it is not possible to determine whether there are pelvic adhesions and lesions. Uterine tubal iodine-oil angiography: to find out what is going on in the lumen of the uterus and fallopian tubes and whether there are pelvic adhesions (although it is not possible to tell where the adhesions are), but it does not solve the problem. It should not be done in people who are allergic to iodine. The patient should never be allowed to push the iodized oil on herself while the doctor hides. Smears must be taken to help recognize the presence of hydrosalpinx and pelvic adhesions. Laparoscopy: observe the specific situation, such as adhesions, endometriosis, can partially solve the problem, but can not see the uterine and tubal cavities. Minimally invasive surgery, high cost. How to choose the way of tubal examination? Sometimes it is really difficult to decide. It should be based on the patient’s specific situation, and repeated passes and imaging should be avoided, as they do not solve the problem and are unlikely to melt away adhesions that are already scarred. Every pelvic manipulation may create an opportunity for pelvic infection. Routine ultrasound (not fluid under ultrasound) will not show if the tubes are open or not. Fluid buildup in the fallopian tubes can sometimes be seen on routine ultrasound, and as estrogen levels in the body get higher, the fluid buildup gets bigger and bigger, along with fluid buildup in the uterine cavity. The mucosa of the fallopian tubes is also affected by sex hormones and has periodic histologic changes, but they are not as pronounced as the endometrium.
