What is the best amount of endometrium for in vitro fertilization?

In recent years, there are more and more women suffering from infertility. Some women can only conceive through test tubes, but when doing test tubes, the body needs to meet the standards for test tubes. Although it is a test tube, the role of the endometrium is very large. The thickness of the endometrium will affect the implantation of the embryo. If the endometrium is too thick or too thin, it will affect implantation and is not conducive to conception.

What is the best amount of endometrium for in vitro fertilization?

The intima of the test tube transplant is 9-12mm, and type A is the best morphology. The endometrium must be at least 7mm thick for transplantation. The endometrium is too thin and it is difficult for the embryo to implant. If the endometrium is too thick or the echo is uneven, there may be endometrial polyps or other lesions that affect embryo implantation. Therefore, it is best if the endometrium is neither too thin nor too thick. People with thin endometrium can choose alternative cycles, take oral Progynova or estrogen vaginal suppositories to make the endometrium reach more than 7mm. It can also be transplanted during a Gn-promoting cycle, or a down-regulation cycle.

Generally speaking, the endometrium refers to the layer that makes up the inner wall of the uterus, which is the mucous membrane covering the uterine cavity. It is one of the most differentiated tissues in the human body. Its function is to form menstruation when not pregnant and to proliferate rapidly during pregnancy to provide nutrition for the growth and development of the embryo. The thickness of the normal endometrium changes with the menstrual cycle and is not constant. The endometrium is divided into the basal layer and the functional layer. The basal layer is not affected by the changes in ovarian hormones during the menstrual cycle and does not fall off during the menstrual period; the functional layer is affected by ovarian hormones and shows periodic changes, and becomes necrotic and falls off during the menstrual period. Therefore, the thickness of the endometrium is not a fixed value, it will change cyclically with the menstrual cycle.

The endometrium changes according to the menstrual cycle. Don't worry if one examination does not meet the requirements. After conditioning and treatment, most people can achieve conception. Pay attention to relaxing your mind, eating a balanced diet, maintaining a regular work and rest schedule, and having regular physical examinations.

Symptoms after IVF transplantation

1. Abdominal pain after transplantation

Mild abdominal pain, sometimes like a pins and needles, in any location and at any time - this condition is usually not serious. Infertile patients tend to pay too much attention to their abdomen, which is mostly related to mental stress. However, if the symptoms of discomfort gradually worsen, you should go to the hospital for treatment. If you have sudden severe abdominal pain, you should go to the hospital immediately. If you experience abdominal pain after egg retrieval, you should be alert to internal bleeding. Sudden abdominal pain after egg retrieval and transplantation is often related to ovarian incarceration or torsion. It is common in patients who have more egg retrieval and ascites.

2. Bleeding after transplantation

The site of bleeding should be noted. Common conditions include: cervical and vaginal inflammation, and bleeding from the needle hole during egg retrieval. Generally, the bleeding will not be too much, but there may be a small amount of bloody secretions. If the bleeding is heavy and lasts for a long time, you should go to the hospital to find out the location of the bleeding and, if necessary, undergo an ultrasound examination to see if there is intrauterine bleeding. If it is intrauterine bleeding, don't be nervous. Generally, the doctor will advise you to observe for a while, pay attention to rest, increase the dosage of "pregnancy-preserving" drugs or come for a consultation, and be hospitalized for observation if necessary. If the bleeding is heavy, such as menstrual flow, or exceeds menstrual flow, you should see a doctor immediately.

3. Abdominal distension and chest tightness after transplantation

Symptoms of abdominal distension and chest tightness may also occur after test tube transplantation, which is mostly related to progesterone injection, reduced intestinal motility, and excessive rest. After the transplant, you should rest for 2-3 days and then go back to work, as long as you don't do heavy physical labor and avoid activities that increase abdominal pressure. However, if the patient's estrogen level is too high on the day of HCG injection or too many eggs are retrieved, more attention should be paid. Be alert for the development of ovarian hyperstimulation syndrome (OHSS). If the symptoms gradually worsen, you should go to the hospital immediately.

4. Constipation after transplantation

If you find symptoms of constipation after IVF transplantation, you should pay more attention. Because progesterone drugs are needed to preserve the fetus after IVF transplantation, and patients tend to be more sedentary than active, have a more meticulous diet, and have reduced intestinal motility, which can sometimes lead to constipation. When the condition is mild, it can be corrected by adjusting the diet structure, such as eating more vegetables and fruits, a high-fiber diet, exercising moderately, and avoiding excessive bed rest. If constipation lasts for a long time and the above methods cannot relieve the symptoms, you can take laxatives appropriately. Please read the instructions carefully before taking them to see if they are contraindicated for pregnant women.
