Concept and background of three generations of IVF

The third generation of IVF refers to the medical process of fertilizing the sperm and eggs of couples with genetic diseases or infertility in the laboratory through in vitro fertilization embryo implantation technology, and then implanting healthy embryos into the mother's body to help couples achieve their reproductive aspirations.

At present, three generations of IVF have become the hope and choice of many infertile couples, such as reverse enhancement of human disease gene mutation, preparation of normal embryos by manually controlled chromosome separation, and changes in the number of chromosomes in the cytoplasm of oocytes.

To carry out three generations of IVF, a formal hospital should be selected, such as the Reproductive Medicine Center of Peking Union Medical College Hospital and the Reproductive Center of Shanghai First Maternal and Infant Health Hospital.

Specific steps of the third generation IVF

The specific steps of the third generation IVF mainly include:

1. In vitro fertilization: When the female body is in the ovulation period, the doctor will extract multiple mature eggs. Then, sperm and eggs are fertilized in vitro in the laboratory, and the formation of fertilized embryos is observed.

2. Embryo culture: After in vitro fertilization, the fertilized egg will further develop in the culture dish. The doctor will monitor the development of the embryo and screen out the well developed embryo.

3. Embryo implantation: When the embryo develops to an appropriate stage, the doctor will implant a healthy embryo into the female uterus, hoping to successfully implant and form a placenta.

In addition to the above basic steps, other auxiliary technologies such as embryonic chromosome screening and chromosome repair may also be required according to the specific situation of the patient.

Key factors of third generation IVF

The key factors for the success of three generations of IVF mainly include:

1. High quality sperm and eggs: Successful fertilization requires high-quality and dynamic sperm and eggs.

2. Quality control: try to improve the success rate of embryo culture and select embryos with well developed cells for implantation.

3. Progesterone support: Progesterone is an important hormone to maintain embryo implantation and embryo development. If the body's own secretion of progesterone is insufficient, exogenous progesterone support is required.

4. Fine operation: doctors need to be very careful and precise in the process of egg retrieval and embryo implantation to avoid harm to the body.

Summary of three generations of IVF

Three generation IVF is an effective way to help infertile couples realize their reproductive dreams. The steps include in vitro fertilization, embryo culture and embryo implantation, which need to be operated in a formal hospital. Key factors include high-quality sperm and eggs, quality control, progesterone support, and fine manipulation. Through high-quality technology and careful operation of the medical team, we hope to help more couples achieve their fertility aspirations.
