Egg retrieval without anesthesia

Egg retrieval is an operation for women who have fertility needs but do not want to have children for the time being. It also includes donation. During this operation, the patient's whole body needs to be carefully examined to see whether it meets the surgical standards. Many people think that anesthesia will harm the body, so they do not plan to use anesthesia before the operation. However, because there are procedures during the operation, in order to ensure safe retrieval, let us take a look at the surgical process.

The process of artificial egg retrieval is as follows:

1. IVF registration and physical examination

Reproductive centers in our country are only allowed to freeze eggs for women undergoing in vitro fertilization. If there are extra eggs and both husband and wife agree, they can also be donated. Relevant physical examinations are required before freezing eggs.

2. Take ovulation injection to retrieve eggs

If you want to retrieve eggs, you must first give women an injection to promote follicle maturation after gonadotropin stimulates egg development. About 36 hours later, the doctor will, under the guidance of B-ultrasound, penetrate the vagina into the ovary and suck out the follicular fluid of the follicle. Through B-ultrasound, we can see that a transparent, crystal-ball-like substance is the follicle, which contains the mature egg. The egg retrieval procedure usually takes no more than 10 minutes.

3. Follicular fluid is sent to the laboratory

The doctor aspirates the follicular fluid into a test tube and quickly passes it through a window to a microscope in the laboratory. The entire egg freezing process is performed in the laboratory. Eggs are very delicate and are afraid of light, cold and heat, so the entire egg retrieval process must be completed quickly in a dark environment.

4. Extraction of oocytes

The egg cells are suspended in the follicular fluid. Laboratory technicians will first separate the egg cells from the follicular fluid under a microscope.

5. Egg dehydration

Laboratory staff dehydrate the eggs by placing them in a highly concentrated dehydrated cryoprotectant solution.

6. Quickly put it into a special container with liquid nitrogen

The dehydrated eggs are immediately placed in liquid nitrogen, a process called vitrification.

7. Put it in liquid nitrogen tank

The eggs are transferred to a liquid nitrogen tank at minus 198 degrees Celsius for long-term storage. Each egg has a corresponding number for future use.

8. Rewarm during use

Some time later, when the woman wants to use the eggs, professional technicians remove the eggs from the liquid nitrogen, rewarm them, and use a solution to remove the chemicals used to make the eggs. The surviving eggs are fertilized in vitro with the male's sperm to develop into embryos. About 3-5 days later, the healthiest embryos are selected and transferred into the woman's uterus.
