Steps and processes of IVF

IVF is an assisted reproductive technology that can help couples who cannot conceive naturally realize their reproductive dreams. The steps and processes of IVF will be described in detail below.

Step 1: Preliminary examination and treatment plan

The first step of IVF is to conduct a preliminary examination and evaluation. Couples need to undergo comprehensive physical examination, including blood examination, reproductive system examination, etc., to determine the suitability of IVF technology. The doctor will also ask the couple about their birth history and learn about possible fertility problems.

After the preliminary examination and evaluation, the doctor will develop a personalized treatment plan. This program will be based on the special circumstances of the couple, including anti ovulation therapy, hormone therapy or other auxiliary means. The doctor will explain the process, risks and effects of the treatment plan in detail.

Next, we will enter the actual treatment stage.

Step 2: ovulation induction

In order to increase the probability of pregnancy, doctors will use drugs to promote women's ovarian ovulation. This is usually achieved by taking orally or injecting drugs.

Doctors will monitor the growth of female follicles and conduct regular ultrasound examinations. Once the follicle grows to the proper size, the doctor will give drugs to stop the development of mature follicles and determine the best time to take eggs.

Step 3: Egg taking and sperm treatment

Eggs are usually taken by puncturing the ovaries. Before the egg retrieval operation, the doctor will use local anesthesia or general anesthesia to ensure the patient's comfort. Doctors will use ultrasound to guide fine needles into the ovary and extract mature eggs from the follicle.

At the same time, men need to provide semen samples. Sperm samples are processed and prepared in the laboratory.

Step 4: In vitro fertilization and embryo transfer

The extracted eggs and sperm will be fertilized in vitro in the laboratory. Doctors add sperm to the eggs in the culture dish to encourage natural fertilization. If natural fertilization cannot be achieved, doctors can also choose to inject a single sperm into the egg to achieve artificial insemination (ICSI).

The fertilized eggs in the culture dish will continue to be cultured in the laboratory. Generally, the best fertilized egg will be selected after 24-48 hours of culture. The doctor will decide with the couple how many embryos to transfer back to the uterus according to the quality and quantity of the fertilized eggs.

Once the embryo transfer is completed, the couple needs to rest for a while and wait for the results.

summary

The steps and processes of IVF generally include preliminary examination and treatment plan, ovulation promotion, egg retrieval and sperm treatment, as well as in vitro fertilization and embryo transfer. During the whole process, doctors will develop personalized treatment plans according to the couple's conditions, and conduct comprehensive monitoring and inspection. Although IVF technology has brought new fertility opportunities to couples who cannot conceive naturally, it also faces some risks and uncertainties. Therefore, couples should fully understand the whole process and fully communicate and consult with doctors before IVF.
