Background
IVF is a kind of assisted reproductive technology, which is suitable for couples who cannot conceive naturally due to various reasons. In Shenzhen, as a modern metropolis, there are many hospitals with IVF technology, of which Shenzhen Hospital of the Armed Police Force is the only one in Shenzhen with IVF technology. The success of IVF technology is related to many factors. Next, we will elaborate on ovarian preparation, egg retrieval, fertilization, embryo culture and other aspects.

Ovarian preparation
The first step of IVF is to regulate the ovarian function of women through drugs to produce enough follicles. According to the patient's condition, the doctor will develop a personalized program for ovarian stimulation, monitor the growth of follicles, and inject ovulation promoting drugs when the optimal size and quantity are reached. Generally, we need to go through 2-3 weeks of ovarian preparation. This process requires regular return to the hospital for ultrasonic examination and blood testing to ensure the maturity of follicles and the health of the body.
The success of ovarian preparation has an important impact on the success rate of follow-up IVF. The number and quality of follicles determine the number and quality of fertilized eggs. Through reasonable ovarian stimulation and monitoring, doctors can maximize the success rate of IVF.
Egg taking and fertilization
In the ovarian preparation stage, the doctor will judge whether the follicle is mature according to the results of ultrasonic monitoring. When the follicle reaches the appropriate size, the egg will be collected. This process usually requires painless or local anesthesia, and the mature eggs in the follicle are taken out through abdominal puncture or vaginal puncture.
After taking eggs, the next step is fertilization. Usually, the conventional fertilization method in IVF technology, that is, eggs and sperm are naturally fertilized in vitro or culture dishes. Assisted fertilization techniques such as intracytoplasmic sperm injection (ICSI) can also be selected. Through this process, the egg will combine with the sperm to form a fertilized egg, preparing for the next step of embryo culture.
Embryo culture and transfer
Fertilized egg transfer is the last step of IVF technology. In the embryo culture room, the fertilized eggs will be placed in the culture dish, and kept at constant temperature, humidity and appropriate light. The doctor will monitor the embryo, evaluate its quality and development, and select the best embryo for transplantation.
Embryo transfer is usually carried out 2-6 days after fertilization. During transplantation, doctors will transfer the embryo to the uterus of a woman with a fine catheter. The process usually does not require anesthesia, but there may be slight abdominal discomfort. After transplantation, patients need to rest for a period of time, and doctors will carry out corresponding auxiliary treatment to improve the implantation rate of embryos.
summary
The success of IVF technology is not achieved overnight. It needs to go through many stages of fine operation. Shenzhen Armed Police Hospital, as the only armed police hospital in Shenzhen with IVF technology, provides a new way for couples who cannot conceive naturally. With the development of relevant technology and the improvement of medical level, more and more couples have realized their reproductive dreams through IVF.
