Procedures and items of IVF prenatal examination
In vitro fertilization (IVF) refers to a fetus that is assisted by in vitro fertilization (IVF). After years of development, this technology has provided hope for couples who cannot conceive naturally. In the process of IVF, prenatal examination is a crucial link, which can provide patients with detailed information on embryonic development and maternal health. Next, we will introduce in detail the steps and inspection items required for IVF prenatal examination.
Step 1: Basic inspection
First of all, the expectant parents of test tube babies need to have a comprehensive health examination, including full blood cell count, blood type, liver function, kidney function, blood sugar, hepatitis B five, AIDS and other items. These tests can ensure that expectant parents are physically fit for IVF. In addition, prospective parents also need genetic counseling to find out whether there are susceptible genes, genetic diseases and other problems through gene testing, so as to eliminate possible genetic risks.
After determining the health status of the expectant parents, the doctor will start a detailed physical examination of female patients. This includes gynecological examinations and endocrine hormone tests to assess women's fertility. Gynecological examination can determine the shape and abnormalities of the uterus, such as endometriosis, hysteromyoma, etc. Endocrine hormone test can observe ovarian function and menstrual cycle to determine the best time for fertilization.
Next, female patients also need pelvic ultrasound examination to understand the structure and function of the ovary and uterus. This test can detect the presence of polycystic ovary syndrome, fallopian tube blockage and other problems. If necessary, hysteroscopy can also be performed to further observe the condition of endometrium and uterine cavity.
Step 2: ovulation promotion and egg retrieval
In the process of IVF, ovulation promotion is a crucial step. Through the use of ovulation promoting drugs, help female patients produce multiple eggs that can be used for fertilization, and control the timing of fertilization. This step requires close monitoring of follicular growth and changes in endocrine levels.
Generally, when the egg develops to a certain size, the doctor will determine the best time to retrieve the egg according to the number and size of follicles. Egg retrieval is generally carried out 36 hours before follicular maturation. The female patient was placed on the operating table, and the mature eggs were extracted by vaginal puncture and fine needle guided by ultrasound. The whole operation usually lasts for 15-30 minutes.
Step 3: sperm treatment and in vitro fertilization
After the egg retrieval operation, doctors will collect semen samples from male patients. Then, through sperm processing technology, select the best quality sperm and eggs for in vitro fertilization. This is usually to put sperm and egg together in a culture dish for natural fertilization.
After a certain period of culture, the fertilized egg will develop into a multi cell embryo. Doctors will choose the best time and quantity of embryo transfer according to the quality and quantity of embryos. Transplantation is generally carried out 2-6 days after fertilization, and the specific time depends on the doctor's advice and the patient's condition.
Step 4: Monitoring after embryo transfer
After embryo transfer, patients need a period of rest and recovery. Doctors generally advise patients to maintain body position and reduce activity intensity to improve embryo implantation rate. Then, about a week later, the patient needs to carry out blood β - HCG test to confirm whether the embryo is successfully embedded.
If the blood β - HCG test result is positive, it means that the fertilized egg has been successfully implanted, and the patient enters the pregnancy state. After that, according to the doctor's guidance, the patient needs to continue to carry out pregnancy related examinations and monitoring, such as ultrasound examination, blood examination, etc.
Through the above steps, the IVF prenatal examination can comprehensively understand the development of the embryo and the health status of the mother, and provide the couples with appropriate treatment programs. However, due to the different physiological conditions and needs of each person, the specific procedures and items of prenatal examination may be different. Therefore, when choosing IVF, couples should consult a professional doctor to understand the specific steps and inspection items required by a specific hospital.
Summary
Test tube baby birth inspection is a complex and critical process, which needs to go through many steps, such as basic inspection, ovulation promotion and egg retrieval, sperm processing and in vitro fertilization, and monitoring after embryo transfer. Through these inspections and monitoring, we can ensure the healthy development of the embryo and the health of the mother, and provide a reasonable treatment plan for couples. Each step has its importance and role. Therefore, it is recommended that couples understand in detail and communicate with professional doctors before IVF, and choose appropriate hospitals and treatment schemes to increase the chances of success.
