What is the process of IVF feeding?



Flow of IVF feeding pouch

IVF refers to the process of fertilizing and cultivating sperm and eggs in the laboratory through assisted reproductive technology, and then transferring the embryo back to the mother to develop into a baby. In vitro fertilization is one of the key steps, which promotes the development and growth of embryos by putting the fertilized eggs into a special environment to simulate the conditions in the uterus. The following will introduce in detail the process of IVF pouch rearing from egg retrieval, fertilization, culture, transplantation and other aspects.

Egg retrieval process

Fetching eggs is the first step of IVF feeding. First, women need to have an ultrasound examination to determine the development of the eggs. Doctors usually use ovulation promoting drugs on the third day of menstruation to promote the development of follicles. Then, after locating the follicle, the doctor will use a special needle to puncture the ovary and suck out the fluid in the follicle, which contains the egg. This process is usually carried out after local anesthesia, which takes about 10-20 minutes. After the eggs are taken, the eggs will be handed over to the laboratory for processing immediately.

Fertilization process

Fertilization is the second step of IVF feeding. The obtained eggs will be fertilized in vitro with the man's sperm in the laboratory. The traditional method of fertilization is to mix eggs and sperm together and let them naturally fertilize in a Petri dish. However, modern reproductive technology has developed more accurate and efficient fertilization methods, such as single sperm injection (ICSI). ICSI improves the fertilization rate and embryo quality by selecting a high-quality sperm and injecting it into the egg.

Embryo culture

After fertilization, the eggs will continue to be cultured in the laboratory. This process usually takes 5-6 days. In the first few days of culture, the embryo will be placed in a culture medium containing nutrients and necessary to maintain growth. Over time, the embryo will gradually divide and develop. During the culture process, doctors will regularly check and evaluate the quality and status of embryos. Only the best embryos will be selected for transplantation to improve the probability of successful pregnancy.

embryo transfer

After the completion of embryo culture, high-quality embryos will be transferred back to the mother. This is usually a simple painless operation that can be performed in a specialized reproductive hospital. The doctor will use a thin tube to carefully place the embryo into the uterus. The whole process usually takes only a few minutes, and then the patient can rest for a period of time, so that the embryo has the opportunity to implant and develop. To sum up, the process of IVF pouch rearing includes four main steps: egg retrieval, fertilization, embryo culture and embryo transfer. This technology helps infertile couples realize their fertility dreams by simulating conditions in the womb in the laboratory. In practice, this process needs to be carried out in formal and professional reproductive hospitals, such as the Reproductive Center of Peking Union Medical College Hospital in China. With the continuous progress of science and technology, IVF technology will continue to develop, bringing hope and opportunities to more couples who are eager to become parents.
