Steps of IVF process
In vitro fertilization (IVF), also known as in vitro fertilization (IVF), is a kind of assisted reproductive technology, which is suitable for couples who are difficult to conceive naturally. The flow steps of IVF will be described in detail below. 1. Information consultation and evaluation
The first step of IVF is consultation and evaluation. Both husband and wife need to consult a professional reproductive doctor to understand the specific process and possible risks of IVF. Doctors will evaluate the physical condition, reproductive health and living habits of the couple to determine whether it is suitable for IVF.

During the evaluation process, the doctor may require a series of examinations, such as ovulation monitoring, endometrial thickness measurement, semen analysis, etc. These tests aim to accurately assess the fertility of couples and the success rate of IVF.
2. Ovulation promotion and egg retrieval
In the preparation stage of IVF, women need to receive ovulation induction treatment for a period of time. This usually includes taking ovulation promoting drugs to promote ovarian development and produce multiple mature eggs.
Once the ovaries are fully developed, the doctor will arrange an egg retrieval operation. During an operation, the doctor uses a needle through the vagina to extract eggs. This process is usually carried out under local anesthesia and usually does not cause too much discomfort.
The removed eggs will be immediately transferred to the laboratory, where they will be combined with sperm and fertilized. Egg retrieval is usually performed when the egg is mature enough, so the ovary needs to be closely monitored.
3. Fertilization and embryo culture
In the laboratory, the eggs and sperm collected after taking eggs are fertilized in vitro. This can be achieved by directly culturing eggs and sperm together in a culture dish, or by injecting a sperm into an egg using single sperm injection technology (ICSI).
The fertilized eggs will continue to be cultured in the laboratory, usually lasting for 3-5 days. During this period, the embryo will undergo cell division and development, and eventually develop into a multi cell embryo.
The doctor will determine the best pregnancy time according to the quality and development of the embryo. In some cases, doctors may recommend that embryo chromosome tests be performed to screen healthy embryos.
4. Embryo transfer and pregnancy observation
After the embryo develops to the appropriate stage, the doctor will select the embryo with the most development potential for transplantation. This process is usually carried out in the doctor's office, and the embryo can be carefully placed in the uterus using a catheter.
After the completion of embryo transfer, women need to conduct pregnancy observation. This usually includes regular checks of progesterone levels in the blood and possibly an ultrasound examination to detect the development of the embryo. If pregnancy is detected, the doctor will regularly track the growth of the embryo until the stability of the pregnancy is finally confirmed.
summary
The process of IVF can be divided into four main steps: information consultation and evaluation, ovulation promotion and oocyte retrieval, fertilization and embryo culture, embryo transfer and pregnancy observation. Each step has a clear purpose and procedure, which requires the cooperation and efforts of doctors and patients. Through reasonable treatment and medical technology support, IVF technology provides a way of hope for those couples who want to become parents but face difficulties in childbirth.
