Birth of IVF

IVF refers to the process of pregnancy and development in which the fertilized eggs are cultured in vitro through artificial assisted reproduction technology, and then one or more of them are transplanted into the mother's uterus. The birth of IVF technology provides a way of hope for couples who cannot conceive naturally due to reproductive problems.

Collection of eggs and sperm

The first step of IVF is for women to take eggs. Usually, from the second or third day of a woman's menstrual period, the doctor will conduct an ultrasound examination to determine the egg development. Subsequently, by giving ovulation promoting drugs, the follicles develop rapidly and mature eggs are discharged. The operation of egg retrieval is usually carried out in the operating room. Doctors use ultrasound guided fine needle puncture technology to extract mature eggs.

The male sperm collection is relatively simple, usually through manual stimulation or the use of auxiliary tools. The collected sperm is processed and combined with the extracted egg.

In vitro fertilization and embryo culture

In vitro fertilization of eggs and sperm is a key step for IVF. Usually, sperm and egg are placed together for culture to form a fertilized egg. From the second day to the fifth day after IVF, the embryo begins to undergo multiple cell division stages. Doctors will regularly check the growth and development of embryos to select the best embryos for transplantation. In the process of embryo culture, doctors will provide them with appropriate culture media and appropriate environment to promote the growth of embryos.

Embryo transfer and pregnancy

Embryo transfer is the last step of IVF. Doctors use thin tubes to transfer the most promising embryos into a woman's uterus. This process is usually relatively simple and generally does not require anesthesia. After embryo transfer, women need to rest for a period of time so that the embryo can be successfully implanted.

If the embryo is successfully implanted and developed, the woman will become pregnant. Doctors will conduct blood pregnancy tests within a few weeks after transplantation to ensure the successful implantation of the embryo. If the test result is positive, it means that the embryo implantation is successful, and the woman will continue to accept prenatal examination and pregnancy management until the successful delivery.

Summary

The birth of IVF has gone through many steps, such as egg retrieval and sperm collection, in vitro fertilization and embryo culture, embryo transfer and pregnancy. The whole process needs doctors' fine operation and monitoring of embryonic development. With the help of modern medical technology, the success rate of IVF continues to improve, bringing new hope and happiness to those couples who cannot conceive naturally.
