What is IVF

In vitro fertilization (IVF) is a kind of assisted reproduction technology. Through in vitro culture and treatment of eggs and sperm, the fertilized eggs are transferred into the female uterus, so as to achieve embryo implantation and pregnancy. Test tube baby technology is one of the important achievements of modern medicine, which provides a hope for couples who cannot conceive naturally.

How to realize IVF technology

The realization of IVF technology mainly includes the following steps:

1. Ovulation promotion: women receive ovulation promotion treatment and use ovulation promotion drugs to promote the development and maturity of eggs. Doctors can determine the optimal follicular development and timing through ultrasonic monitoring and blood measurement.

2. Egg taking: When the egg is mature, the doctor uses a slender puncture needle to puncture the ovary, take out the egg under the guidance of ultrasound, and put it into the culture medium for preservation.

3. Sperm extraction: men provide semen, and technicians in the laboratory process semen to obtain high-quality sperm.

Implement in vitro fertilization

Laboratory technicians will take out the eggs and sperm for in vitro fertilization. This process can be traditional in vitro fertilization, that is, eggs and sperm are placed in a Petri dish, so that the sperm can combine with the egg itself; Single sperm injection can also be used, that is, single sperm is injected into the egg. These fertilized eggs will be cultured in the laboratory for 2 to 6 days to form embryos.

Embryo transfer and pregnancy

When the embryo develops to the appropriate stage, the doctor selects the appropriate embryo for transplantation according to the patient's age, the results of previous treatments and other factors. Embryo transfer is a simple operation. Doctors use thin tubes to transfer embryos into women's uterus. After successful transplantation, women should continue to take estrogen and progesterone for support treatment to increase the chances of embryo implantation.

If the embryo is successfully implanted and matures, the woman will become pregnant. The doctor will follow up appropriately according to the pregnancy situation and provide necessary health care guidance during pregnancy to ensure the healthy growth of the fetus.

In a word, IVF technology helps couples who are unable to conceive naturally realize their desire to have children through the steps of ovulation induction, egg retrieval, sperm retrieval, in vitro fertilization, embryo transfer and pregnancy.
