Definition of IVF

IVF is a process in which the fertilization process is realized in vitro and the fertilized egg is transferred to the mother's uterus to develop into a baby through assisted reproductive technology. IVF technology is widely used to treat couples with fertility disorders such as uterine malformations, oviduct obstructive diseases, male infertility, etc.

The operation of IVF mainly includes three steps: in vitro fertilization, embryo culture and embryo transfer. The specific operation process of IVF will be revealed in detail below.

In vitro fertilization

In vitro fertilization is the first step of IVF. First, women should receive intravenous ovulation or hormone therapy to promote ovarian development and produce multiple mature eggs. Then, doctors use ultrasound guided puncture technology to remove mature eggs from the ovary.

On the other hand, men provide fresh or frozen semen samples. In the laboratory, doctors put sperm and eggs in nutrient solution to co culture for several hours to promote the combination of sperm and eggs. If fertilization occurs, a fertilized egg will be formed.

Embryo culture

The fertilized egg enters the embryo culture stage. In Petri dishes, doctors maintain the temperature, humidity and nutrient supply of the fertilized eggs under specific conditions. The conventional embryo culture process can be divided into three stages: fertilized egg, four cell stage and blastocyst stage.

A professional embryologist will regularly observe the development of the fertilized egg. Before transplantation, doctors will select the embryos that are most likely to be implanted successfully according to the development status, so as to improve the success rate of IVF operation.

embryo transfer

Embryo transfer is the last step of IVF operation. Doctors will choose the most suitable time to transfer high-quality embryos back to the mother's womb. The transplantation process is usually carried out through the vagina or abdominal cavity.

After transplantation, women need to receive an appropriate rest period to help implantation and embryo development. Later, the doctor will conduct a blood test to confirm whether the pregnancy is successful.

Risk and success rate of IVF operation

Although IVF operation can help many infertile couples realize their dreams, it also has certain risks. Common risks include multiple pregnancy, early abortion, poor blastocyst implantation, etc.

The success rate is affected by many factors, including female age, ovarian reserve, gynecological diseases, etc. According to statistics, the success rate of IVF is usually between 30% and 60%.

Summary

IVF is performed through in vitro fertilization, embryo culture and embryo transfer. Although there are certain risks, IVF has helped many infertile couples achieve their reproductive dreams. Through continuous improvement of technology and medical level, the success rate of IVF operation is also gradually improving.
