Procedure of IVF

In vitro fertilization (IVF) is a reproductive method that uses assisted reproductive technology to complete the combination and culture of sperm and eggs in vitro, and finally transfer embryos to the mother's uterus for development. It has realized the birth dream for many infertile couples or elderly couples. The procedure of IVF is described in detail from four aspects.

1. Preliminary preparation

The preparation of IVF generally includes the following steps. First, both husband and wife need to have a physical examination to understand their reproductive system function. Then, according to the examination results, the doctor will provide necessary advice and suggestions for the couple to evaluate whether it is suitable for IVF. If the couple decides to carry out IVF, the doctor will arrange the date of taking eggs according to the woman's menstrual cycle, and explain the IVF procedure and possible risks to the couple. In this process, couples need to fully understand the mental and physiological pressure of IVF, as well as possible complications, and sign the informed consent form. At the same time, couples also need to be prepared because IVF is a process full of hope, waiting and anxiety.

2. Ovulation promotion and egg retrieval

In the procedure of IVF, the first important step is to promote the development of the woman's ovary through drug treatment to achieve the goal of polycystic follicle development. The doctor will develop a personalized ovulation promotion program according to the specific conditions of the couple, and conduct regular ultrasound examination and blood tests to ensure normal ovarian development. Generally, when polycystic follicles mature, the doctor will arrange for egg retrieval. Egg taking is usually carried out in the operating room, and follicular fluid is collected by puncturing the ovary. This process is usually carried out under local anesthesia or general anesthesia and completed under supervision. After taking the eggs, they will be transferred to the laboratory for in vitro fertilization.

3. In vitro fertilization and embryo culture

In the laboratory, the doctor will culture the obtained eggs together with the sperm of the spouse to fertilize them in the appropriate culture environment. The doctor will choose the appropriate method according to the situation, such as traditional culture method or minimally invasive technology, to complete the fertilization process. After fertilization, the embryo will be transferred to a special culture dish and cultured in the laboratory. In the process of embryo development, doctors will conduct regular observation and evaluation to select appropriate embryos for transplantation. This process generally lasts for 3-5 days.

4. Embryo transfer and pregnancy testing

After the embryo culture reaches a certain level of development, the doctor will select the most promising embryo for transplantation. Embryo transfer is usually carried out without pain, and the embryos are transferred to the mother's uterus through a catheter. This process is fast and painless, but requires professional technology and experience. After implantation, the couple need to take a rest to minimize strenuous physical activity. About two weeks later, the doctor will conduct a blood or urine pregnancy test to confirm whether the pregnancy is successful.

Summary

The procedures of IVF include preliminary preparation, ovulation induction and oocyte retrieval, in vitro fertilization and embryo culture, as well as embryo transfer and pregnancy testing. This process requires both the husband and wife to actively cooperate with the doctor for various examinations and treatments, and make psychological preparations. The emergence of IVF technology has provided a way for infertile couples or elderly couples to realize their reproductive dreams. Through the correct procedures and the assistance of professional medical teams, more and more couples have successfully welcomed their babies.
