Specific steps of IVF

IVF baby, also known as IVF baby, is a kind of assisted reproductive technology, which combines eggs and sperm in vitro, and then transplants the fertilized eggs into the mother's uterus to realize the process of pregnancy and delivery. The specific steps of IVF will be described in detail below.

1. Egg collection and sperm extraction

The first step of IVF is to collect female eggs and male sperm. First, women need to inject a drug to promote the development of follicles and make the eggs mature. Then, at an appropriate time after the eggs mature, the doctor will conduct an egg collection operation. This is usually done by puncturing the ovary with a fine needle guided by ultrasound to extract the eggs from the follicle. For men, sperm extraction is relatively simple. Generally, high-quality and high concentration sperm can be obtained by manual sperm extraction or assisted reproductive technology, such as semen encapsulation or semen washing.

2. In vitro fertilization

After egg collection and sperm extraction, the next step is in vitro fertilization. In the laboratory, eggs and sperm are placed in a culture dish to make them naturally combine or to promote fertilization by injecting sperm into eggs. In this way, doctors can better control the fertilization process and ensure the maximum fertilization rate.

3. Embryo culture

Once the egg is fertilized successfully, the doctor will cultivate the fertilized egg in the laboratory after the fertilized egg is formed. The culture time is usually 2-6 days. The doctor will regularly observe the development of the fertilized eggs and evaluate the embryo quality. In the process of culture, doctors sometimes choose to carry out some auxiliary technologies, such as embryo incubator, nutrition enhancement technology and single embryo culture, to improve embryo quality and pregnancy rate.

4. Embryo transfer

When the embryo culture reaches a certain stage, the doctor will select the best embryo for transplantation. Usually, after 2-6 days of culture, the most promising embryos are selected and transferred to the mother's uterus. Embryo transfer is a simple and painless process, usually carried out in gynecological clinics. Doctors use catheters to transfer embryos into the uterus, and then through natural behavior, let the embryos embedded in the uterine wall and continue to develop.

summary

The specific steps of IVF include egg collection and sperm extraction, in vitro fertilization, embryo culture and embryo transfer. In this process, doctors will develop personalized treatment plans according to the specific conditions of patients and laboratory technology. Although IVF technology has enabled many infertile couples to realize their dreams of fertility, it is still a complex and expensive process that requires close cooperation and understanding between doctors and patients. Through IVF, many couples now have their own babies, bringing endless happiness and hope.
