What is the principle of IVF technology
IVF technology, namely Assisted Reproductive Technology (ART), is a method to help infertile couples achieve fertility. It involves various medical technologies and means, including in vitro fertilization (IVF) and embryo implantation. The principle of IVF technology will be described in detail from four aspects: cell culture, implantation mechanism, drug assistance and surgical operation.
cell culture
The first step of IVF technology is to collect female eggs and male sperm. First, women receive ovulation guidance drugs to promote the development of follicles, and then take out the eggs under the guidance of ultrasound when they are mature. Men provided fresh sperm samples. The egg and sperm combine through in vitro fertilization (IVF) to form a fertilized egg.
The fertilized egg is then transferred to a culture dish for cell culture. In the artificial medium, the fertilized eggs will form embryos with transparent cells through different stages of culture. Cell culture provides a suitable environment to promote embryonic development and cell division, and prepare for subsequent implantation.
Implantation mechanism
In the second step of IVF technology, select the right embryo to be implanted into the female uterus. This process is usually completed through non surgical or minimally invasive surgery.
Non operative implantation, also known as uterine lavage, is the use of a slender catheter to guide the embryo into the uterus. This method is relatively simple and will not cause obvious pain and physical burden.
Minimally invasive surgical implantation, also known as embryo transfer, carefully implants embryos into the uterus by inserting a specially designed catheter into the female uterine cavity. This method requires high operating skills and is completed by experienced professional doctors.
Drug assistance
In the process of IVF technology, drugs may be needed to improve the success rate. The following are commonly used drug aids:
Ovulation guidance drugs: through the use of ovulation promotion drugs for female patients, promote the development of follicles and the process of ovulation, and improve the probability of pregnancy.
Progesterone: In the early stage after fertilization, progesterone can help maintain the stability of the endometrium and enhance the possibility of embryo implantation.
Hormone treatment: According to individual conditions, doctors may give hormone treatment to patients to increase the success rate.
Operation
IVF technology needs a series of surgical operations to complete. These operations include egg collection, embryo culture, embryo implantation, etc., and need to be carried out in a sterile environment.
Egg collection is an operation process requiring comprehensive technology. Doctors use ultrasound and other technical guidance to puncture the ovary with a slender needle tube, extract the eggs from the follicle, and put them into the preservation tube.
Embryo culture is to transfer the fertilized egg into a culture dish and provide appropriate nutrition and culture medium to promote cell division and embryonic development.
Embryo implantation is the transfer of embryos into women's uterus to achieve the goal of pregnancy and childbirth. This operation requires doctors with rich experience and superb skills.
To sum up, the principle of IVF technology is to help infertile couples achieve fertility through the synergy of cell culture, implantation mechanism, drug assistance and surgical operation. The development and application of this technology depends on the progress of medicine and technology, as well as the support and cooperation of professional hospitals and doctors.
