What is the principle of tube baby curettage?
Test tube baby refers to an infant who is pregnant by cultivating embryos in vitro and transplanting them into the mother's uterus through assisted reproductive technology. In the early stage of IVF, curettage is a common process, which is used to clear the endometrium and provide a more favorable environment for embryo implantation. This article will introduce the principle of IVF curettage in detail.
1. Preparation before curettage
In vitro fetal curettage is usually performed in the cycle before embryo transfer to ensure the best condition of endometrium. Before curettage, the doctor will make the following preparations:
First of all, doctors will promote the growth of endometrium through hormone therapy, and make it reach the optimal thickness and maturity. This process usually involves the administration of hormone drugs such as estrogen and progesterone to simulate natural physiological conditions.
Secondly, doctors will use ultrasound to monitor the growth of endometrium. Through regular examination, doctors can determine the best time for curettage to ensure that the growth of endometrium reaches the ideal state.
Finally, the doctor will prepare the endometrium, including subcutaneous injection of anticoagulant drugs to prevent thrombosis, and proper disinfection and cleaning of the cervix and vagina.
2. The process of curettage
Test tube baby curettage is a simple and routine operation, usually performed under painless anesthesia. The specific steps are as follows:
First, the doctor will use a metal curette or an attractive curette to enter the uterine cavity through the cervix. Then, the doctor will gently scrape off a layer of tissue on the surface of the endometrium. This process usually does not cause severe pain, but may cause some discomfort.
The purpose of curettage is to remove the aging endometrium that is not suitable for embryo implantation. By scraping the endometrium, it can stimulate the growth of new endometrium and provide a better environment for receiving the transferred embryo.
Generally speaking, the entire curettage process only takes a few minutes. At the end of the operation, the doctor may ask the patient to take a rest for a period of time and then carry out the embryo transfer.
3. Precautions and recovery process after curettage
After curettage, pay attention to the following:
First, the patient may feel some abdominal pain or slight bleeding. These are normal reactions that usually disappear within a few days.
Second, doctors usually give antibiotics to prevent infection. Patients should take medicine according to the doctor's advice and follow proper cleaning methods to keep the uterus and vagina clean.
In addition, patients need to avoid strenuous exercise and sexual activity to avoid stimulating the uterus and possibly causing infection. Usually, doctors will advise patients to avoid pregnancy for a period of time after surgery to ensure that the endometrium returns to its optimal state.
4. Effects and risks of curettage of test tube babies
Curettage of IVF plays an important role in improving the success rate of IVF. By curettage, the endometrium that is not suitable for implantation can be removed, providing a better environment for the embryo, thus increasing the success rate of embryo implantation.
However, IVF curettage also has certain risks. Curettage may cause complications such as uterine bleeding, infection or perforation. Therefore, before the curettage operation, the doctor will evaluate the patient's health to determine whether the operation is suitable.
In general, curettage of IVF is an important step in IVF technology. The success rate of IVF can be improved by clearing the endometrium and providing an environment more conducive to embryo implantation. This process is usually safe and effective, but patients also need to pay attention to postoperative recovery and follow the doctor's advice.
