Test tube baby Long Feng: How to carry out embryo transfer?
As an assisted reproductive technology, IVF technology provides a hope for couples who cannot conceive naturally. Embryo transfer is one of the key steps for IVF, and its success directly determines whether IVF can be born in the end. The process of embryo transfer will be described in detail in terms of patient preparation, embryo culture, transfer technology and success rate.
1、 Patient preparation
Before IVF embryo transfer, patients need to have a comprehensive physical examination and have a detailed understanding of the process of embryo transfer and the drugs used. The doctor will make a personalized treatment plan according to the patient's age, medical history and fertility.
First, patients need to undergo endocrine tests to determine ovarian function and uterine conditions. If the patient's ovarian function is poor or the endometrium is abnormal, it may be necessary to carry out auxiliary treatment, such as ovulation induction and endometrial stimulation.
Next, the patient began ovulation promoting drug treatment to promote ovarian development and follicle growth. The doctor will adjust the drug dose according to the patient's condition, and monitor the development of follicles through ultrasonic inspection.
2、 Embryo culture
In the patient preparation stage, doctors will collect women's eggs and use sperm for in vitro fertilization. The fertilized eggs are cultured in vitro.
During the process of embryo culture, doctors will closely monitor the development of the fertilized eggs. Generally, the embryo will go through 2 to 6 days of development in the incubator, forming embryos at different stages. Doctors will select the most promising embryos for transplantation according to the quality and development of the embryos.
Some hospitals can also provide embryo cryopreservation services for patients. This can provide more opportunities for patients, not only reducing the drug use and examination times in each cycle, but also improving the success rate.
3、 Transplantation technology
Embryo transfer is usually carried out after the patient has been properly prepared. After puncturing and sucking the fertilized egg, the doctor will use a catheter to send the embryo into the uterine cavity.
With the progress of science and technology, the transplantation technology is also improving. Today, doctors can use high-resolution ultrasound guidance technology to accurately send embryos into the endometrium. This technique can improve the survival rate of embryos and the success rate of transplantation.
Embryo transfer usually does not require anesthesia and is less painful. Patients can leave hospital immediately after operation. The doctor will give the postoperative precautions and make a prenatal examination plan according to the patient's condition.
4、 Success rate
The success rate of embryo transfer mainly depends on the patient's age, the quality of eggs and sperm, the quality of embryos and transfer technology. In general, young patients, high-quality eggs and embryos, and precise transfer techniques will improve the success rate.
According to statistics, the success rate of IVF is between 20% and 60%, depending on the experience level of different hospitals and doctors. Some top IVF hospitals have rich experience and advanced equipment in embryo transfer, and the success rate is usually high. For example, a hospital in Beijing, China, has a good reputation in the field of embryo transfer.
Summary
Through the above introduction, we understand that the process of IVF embryo transfer includes patient preparation, embryo culture, transfer technology and success rate. Patients need to conduct comprehensive examination and preparation, and select suitable embryos for transplantation during embryo culture. The improvement of transplantation technology and the advancement of hospital equipment have a direct impact on the success rate. Finally, we learned that choosing a hospital with good reputation and rich experience also plays an important role in the success rate of IVF.
