Medical technology of IVF
Test tube baby refers to the technology of cultivating embryos in test tubes and then transplanting them into the mother's uterus to achieve pregnancy and fertility. With the progress of science and technology, IVF technology has developed continuously, covering many aspects of medical technology. This article will introduce the medical technology of IVF from four aspects: germ cell acquisition, assisted reproductive technology, embryo implantation and pregnancy monitoring.
? Germ cell acquisition
? The first step of IVF technology is to obtain germ cells from men and women, mainly including sperm and eggs. In terms of sperm acquisition, the commonly used method is to urinate naturally or extract semen samples. In terms of oocyte acquisition, ovarian stimulation technology and follicle puncture technology are usually used. Ovarian stimulation technology promotes the development and maturation of multiple follicles by giving female hormone drugs, and then collects the eggs by follicle puncture technology.
? For those women who are unable to pick up their eggs, they can also obtain germ cells through egg donation. The reproduction center will screen, select suitable egg donors, and conduct egg acquisition and follow-up operations. These germ cell acquisition technologies provide a basis for the implementation of IVF.
? Assisted reproductive technology
? Assisted reproductive technology in IVF mainly includes in vitro fertilization (IVF) and embryo implantation. In vitro fertilization refers to in vitro fertilization of sperm and eggs in a test tube to form a fertilized egg. This process usually needs to be carried out in the laboratory of the reproductive center, and requires a series of operations and technical support.
? Embryo implantation is the implantation of embryos obtained by in vitro fertilization into the uterus of women. This process is usually performed by hysteroscopy in the operating room of the hospital. The doctor will implant the embryo into the uterus in an appropriate way, and then conduct follow-up pregnancy monitoring.
? Embryo implantation
? Embryo implantation is one of the core steps of IVF technology. In the process of embryo implantation, the doctor will implant the embryos cultivated in the laboratory into the female uterus and conduct subsequent pregnancy monitoring.
? The technology of embryo implantation has been developing continuously, and the commonly used method is hysteroscopy. This technology can minimize the risk of artificial implantation and improve the success rate of embryo implantation. In some cases, frozen embryo implantation technology can also be used to implant frozen embryos into the uterus.
? Pregnancy monitoring
? Pregnancy monitoring is the last step of IVF technology. After embryo implantation, pregnancy needs to be monitored timely and comprehensively. This process usually includes blood testing, B-ultrasound examination and pregnancy related indicators monitoring.
? The purpose of pregnancy monitoring is to ensure the successful implantation of embryos and maintain the stability of pregnancy. The doctor will adjust the pregnancy management plan according to the monitoring results to ensure the success of IVF.
? Summary
? The medical technology of IVF involves germ cell acquisition, assisted reproductive technology, embryo implantation and pregnancy monitoring. High quality sperm and eggs can be obtained through the acquisition of germ cells. Assisted reproductive technology, including in vitro fertilization and embryo implantation, can provide technical support for the success of IVF. Embryo implantation is the core step of IVF technology. Hysteroscopy and frozen embryo implantation can improve the success rate. The purpose of pregnancy monitoring is to ensure the stability of pregnancy and adjust the management plan through the monitoring results. The continuous progress and innovation of IVF medical technology provides a hope for couples who cannot conceive naturally to achieve their fertility aspirations.
