Test tube baby: five key steps

Test tube baby technology is an important breakthrough in modern medical science and technology, which provides an important solution for couples facing fertility barriers. The process of IVF involves several key steps, each of which requires precise operation and in-depth understanding. The key steps of IVF will be described in detail in the following five aspects: egg retrieval, sperm treatment, in vitro fertilization, embryo culture and embryo transfer.

1. Take eggs

Fetching eggs is the first step of IVF technology. This process usually starts on the first day of a woman's menstrual cycle. Doctors will monitor the growth of follicles through ultrasonic technology. Once the follicles are developed to the proper size, doctors will carry out egg retrieval operations. Egg retrieval is usually performed through the vaginal route, and doctors will use ultrasound guidance to guide the operation. During the operation, the doctor will puncture the ovarian follicle and extract the eggs from the follicle. These eggs will be immediately sent to the laboratory for subsequent treatment. During egg retrieval, doctors need to pay special attention to avoid any possible complications. In addition, accurate calculation of the number and quality of eggs is very important for successful in vitro fertilization and embryo culture.

2. Sperm treatment

Sperm processing is the second critical step in IVF. In the laboratory, sperm usually goes through a series of processing steps to purify sperm and select the best quality sperm for in vitro fertilization. Common treatment methods include removing inactive sperm, sperm centrifugation and using high-quality medium to improve fertilization rate. Through sperm treatment, doctors can select the best quantity and quality of sperm to improve the success rate of in vitro fertilization.

3. In vitro fertilization

In vitro fertilization is one of the key steps in IVF technology. This process is to combine the best sperm selected with the eggs obtained from egg retrieval in the laboratory. Normally, doctors will inject sperm directly into the egg, which maximizes the chance of fertilization. After in vitro fertilization, doctors will observe the development of the fertilized eggs to determine which fertilized eggs have the best development potential, so as to further cultivate and select the most promising embryos.

4. Embryo culture and embryo transfer

Embryo culture and embryo transfer are the last two key steps in IVF technology. After in vitro fertilization, the fertilized eggs will be cultured in the laboratory to determine which embryos have the best development potential. Doctors will observe the development of embryos, cell division speed, embryo quality and other factors to determine the best embryo for transplantation. In embryo transfer, the doctor will insert the selected embryo into the female uterine cavity through a very thin tube. The process is usually simple, short and painless.

summary

The five key steps in IVF are egg retrieval, sperm treatment, in vitro fertilization, embryo culture and embryo transfer. Each step requires rigorous operation and professional technical support. By precisely controlling each step, doctors can improve the success rate of IVF technology and realize their dreams for those couples who cannot conceive naturally. This technology has been applied in many formal hospitals around the world, and has brought joy and hope to thousands of families.
