Definition of IVF
IVF refers to a method of cultivating the fertilized egg to a certain extent during IVF, and then implanting it into the female uterus for development, so as to achieve pregnancy and fertility through assisted reproductive technology. This method is widely used in many infertility patients, including fallopian tube blockage, male infertility, endometriosis and other diseases.
The whole process of IVF technology includes the following steps: first, women receive hormone therapy to promote ovarian development; Secondly, the mature eggs are taken out after the egg retrieval operation; Then, in the laboratory, eggs are combined with sperm to produce fertilized eggs; Finally, the fertilized egg is cultured to an appropriate stage, and then implanted into the female uterus, waiting for embryo implantation and pregnancy.
Success rate of IVF
The success rate of IVF is related to many factors, including age, reproductive health, lifestyle, etc. According to the data, the success rate of IVF is about 35% to 45% worldwide. However, the data may be different for each country and region.
Age is an important factor affecting the success rate of IVF. Generally speaking, the younger the female, the higher the success rate of IVF. The quality of young women's eggs is better, which is more suitable for fertilization and embryo implantation. In addition, for patients with some reproductive system diseases, such as polycystic ovary syndrome, the success rate of IVF is also low.
In addition, male sperm quality will also affect the success rate of IVF. Men with poor semen quality may have low sperm quantity and vitality, which will reduce the probability of fertilized eggs formation and embryo implantation.
Medical practice of IVF
IVF technology is widely used in the world. Many hospitals and clinics provide IVF treatment, such as Massachusetts General Hospital in the United States and Queen's Hospital in London in the United Kingdom.
In medical practice, IVF needs to undergo a series of examinations and treatments to ensure the safety and success of treatment. First of all, patients need to have a comprehensive physical examination and gynecological examination to determine whether their physical condition is suitable for IVF. Then, according to the specific situation of the patient, appropriate hormone treatment program is formulated to promote ovarian development. Before the egg retrieval operation, some nursing and preparation work should be carried out.
During the whole treatment process, the doctor will closely monitor the patient's physical condition and ovarian development. After the egg retrieval operation, the doctor will select the best egg to combine with the sperm to produce a fertilized egg. Then, the fertilized eggs are cultured in the laboratory, and the embryos with the most development potential are finally selected to be implanted into the female uterus.
Summary
IVF is a method to help infertility patients achieve fertility through in vitro assisted reproductive technology. The success rate is closely related to age, reproductive health and other factors. At present, the success rate of IVF in the world is about 35% to 45%. IVF treatment needs to be carried out in hospitals or clinics, and needs to go through a series of examinations and treatment processes. Although IVF technology can help infertility patients realize their dreams in some cases, before choosing this method, patients should fully understand its risks and uncertainties, and make decisions under the guidance of professional doctors.
