Operation steps of IVF

IVF is a kind of assisted reproductive technology, which can help couples who cannot conceive naturally realize their desire to have children. It involves many steps and technologies, including ovulation induction, egg collection, sperm egg combination and embryo transfer. The following steps are for IVF.

Step 1: ovulation induction

First, women need to receive ovulation induction therapy. This treatment uses hormone drugs to stimulate the ovaries to produce multiple eggs. This can increase the probability of pregnancy and provide enough embryos for selection.

During this period, the doctor will regularly monitor the ovarian response, and use ultrasound and blood tests to determine the best time for the next step.

Once the follicle develops to a large enough size, the doctor will recommend that the woman inject a drug to trigger the maturation of the egg, and the egg is scheduled to be collected within a certain time.

Step 2: Egg collection

Egg collection is usually carried out in the operating room. During the operation, the doctor will use ultrasound to guide a slender needle to puncture the ovary, and then use the needle to extract the mature eggs.

This process usually requires anesthesia and is guided by the lens to ensure accuracy. The eggs collected will be immediately handed over to the laboratory for subsequent processing.

Step 3: Fertilization and embryo culture

In the laboratory, sperm is extracted and then combined with eggs. This process can be achieved by directly adding sperm to the culture dish, or through a technology called single sperm injection.

After fertilization, the eggs will continue to be cultured in a petri dish. During this process, the development of the embryo will be carefully monitored. Normally, the embryo will be cultured in the culture dish for at least 5 days until it reaches the full development stage.

Step 4: Embryo transfer

Embryo transfer is the next step in IVF operation. This process usually does not require anesthesia, and can be completed in the doctor's office or special operating room.

Doctors will use a slender catheter to carefully place one or more of the multiple embryos into the female uterus. This requires technology and experience to ensure successful implantation.

Within weeks after transplantation, women may need to continue to use hormone drugs to help the embryo implant in the uterus and continue to develop.

Implementation of IVF operation

The operation of IVF needs to be carried out under the guidance of professional doctors, usually in specialized reproductive medical centers or hospitals. The following is the implementation process of IVF operation:

1. Patient consultation: couples should first consult the doctor about the applicability and possible risks of IVF. The doctor will conduct a detailed health examination and relevant tests on the patient.

2. Treatment plan: The doctor formulates a personalized treatment plan for IVF according to the patient's physical condition and examination results, including ovulation promotion plan and drug treatment plan.

3. Surgical preparation: Before egg collection and embryo transfer, the patient needs to carry out necessary surgical preparation and physical examination. This may include developmental assessment, blood tests and reproductive system tests.

4. Operation process: The operation process of IVF is completed by a professional team of doctors. They will perform each step accurately to ensure the success and safety of the operation.

Summary

The operation steps of IVF include ovulation induction, egg collection, fertilization and embryo culture, and embryo transfer. These steps need to be carried out under the guidance of professional doctors and in special reproductive medical centers or hospitals. The IVF operation needs to be carried out according to the personalized treatment plan, and the professional doctor team is responsible for the implementation. Through these steps and implementation measures, IVF technology can help couples who cannot conceive naturally realize their reproductive dreams.
