Operation process of IVF technology

IVF technology, also known as in vitro fertilization (IVF) technology, is an assisted reproductive technology designed to help couples who cannot conceive naturally achieve their reproductive aspirations. It involves many complicated operation steps and technologies. The following will elaborate the operation process of IVF technology from four aspects.

1. Women's side preparation

First, women need to undergo preliminary fertility related tests, including blood and genital tests. After the diagnosis, the doctor will make a treatment plan according to the woman's menstrual cycle. Since then, women need to receive a series of drug treatments to promote the development and maturation of eggs. These drugs are often hormone drugs, which are used by injection or oral administration. The doctor will regularly conduct ultrasonic examination and blood test to monitor the development of eggs and endometrium. When the eggs develop to their best condition, doctors usually arrange for egg retrieval. During the egg retrieval operation, doctors will use ultrasound guided slender needles to puncture the ovary and extract eggs. This is a routine minimally invasive surgery and is performed under general anesthesia. After taking the eggs, women may feel some pain and discomfort, but it is usually not serious, and usually returns to normal after a few days.

2. Male side preparation

During the treatment of the woman, the man needs to provide a semen sample. Under normal circumstances, doctors will instruct men to take samples 2-5 days after having no sex. In some special cases, such as men suffering from azoospermia, doctors may recommend that semen be obtained through stimulation techniques (such as testicular puncture or sperm extraction). After sampling, semen samples will be sent to the laboratory for sperm processing and preparation.

3. Fertilization and embryo culture

In the laboratory, the obtained eggs will be assisted with semen for fertilization. This can be achieved by two methods: one is to put eggs and sperm in a culture dish and let them naturally fertilize in the culture dish; The other is to inject a sperm into an egg. Then, the fertilized eggs will enter the incubator for culture, providing an appropriate environment to simulate the conditions in the uterus. The temperature, humidity and nutrients in the incubator need to be strictly controlled. During embryo culture, doctors usually monitor and evaluate the development of embryos. Usually, the embryo stays in the incubator for 3-5 days until it reaches the appropriate development stage.

4. Embryo transfer

At the end of the embryo culture period, the doctor will select the best embryo for transplantation according to the development of the embryo. Embryo transfer is a simple process, usually carried out in the doctor's office, without anesthesia. The doctor will insert the embryo into the woman's uterus through a slender tube. This process usually does not cause discomfort or pain.

Summary

The operation process of IVF technology mainly includes female side preparation, male side preparation, fertilization, embryo culture and embryo transfer. Women's side preparation includes drug treatment, egg retrieval operation and recovery process. Men need to provide semen samples. After taking eggs and semen samples, fertilization and embryo culture are carried out in the laboratory. After embryo culture, select the best embryo for transfer. The whole process requires close cooperation between doctors and laboratory personnel. Through IVF technology, couples who cannot conceive naturally have the opportunity to achieve their reproductive aspirations.
