How is IVF operated?
In vitro fertilization (IVF) refers to the process of pregnancy and pregnancy by means of artificial assisted reproduction (ART), in which women's eggs and men's sperm are fertilized in vitro, then embryos are cultivated in the laboratory, and finally the embryos are implanted into women's uterus. The operation of IVF includes the following main steps:
The first step is ovulation induction therapy for women. By using ovulation promoting drugs or injecting human chorionic gonadotropin (HCG), ovarian ovulation is promoted and the development of eggs is monitored.
The second step is to collect eggs. Within 24 to 36 hours after ovarian ovulation, through penetration of the female vagina and uterine wall, under the guidance of an ultrasound probe in the ovary, use a slender needle tube to extract eggs.
The third step is to collect sperm. Men provide semen in the laboratory, in which the sperm is professionally processed to select the most active and high-quality sperm.
The fourth step is in vitro fertilization. Put the collected eggs and sperm together in the culture dish to promote the sperm to naturally combine with the egg to form a fertilized egg. This process can be carried out naturally, and micromanipulation technology can also be used to help egg and sperm combine.
The fifth step is embryo culture. The fertilized eggs continue to be cultured in the culture dish until they reach the embryonic stage of 5 to 6 days. During this period, professional technicians will regularly observe the development and quality of embryos, and select high-quality embryos for implantation.
The sixth step is embryo implantation. The high-quality embryo is implanted into the female uterus through the vaginal or abdominal approach. The process is usually carried out under local anesthesia, which will not bring greater pain to the patient.
Step 7: pregnancy monitoring. After embryo implantation, it is necessary to conduct corresponding pregnancy monitoring, including blood HCG detection, ultrasound examination, etc., to determine whether the pregnancy is successful.
How to improve the success rate of IVF?
The success rate of IVF is affected by many factors, including age, lifestyle, basic diseases, etc. However, there are other ways to improve the success rate of IVF:
First, choose the appropriate hospital. Choose a regular hospital with rich experience and professional team to perform IVF operation. The technical level and equipment conditions of doctors have an important impact on the success rate.
Secondly, pay attention to lifestyle and health. Keeping good living habits, balanced diet, proper exercise, smoking cessation and alcohol restriction can improve the quality of eggs and sperm and increase the implantation rate of infants.
In addition, adjuvant treatment was carried out. Compared with single IVF technology, auxiliary treatment methods such as intracytoplasmic sperm injection (ICSI) and embryo cryopreservation can improve the success rate of IVF to a certain extent.
Finally, maintain mental health. The pressure and anxiety during IVF often affect the whole process. It is suggested that both husband and wife should actively participate in psychological consultation, learn to cope with emotional fluctuations, and maintain a positive attitude.
summary
Test tube baby is a kind of assisted reproductive technology, which realizes pregnancy and pregnancy through manual operation. The operation process includes ovulation induction therapy, egg and sperm collection, in vitro fertilization, embryo culture, embryo implantation and pregnancy monitoring.
In order to improve the success rate of IVF, it is necessary to select appropriate hospitals, maintain a healthy lifestyle, carry out adjuvant treatment, and maintain good mental health. Although there are many factors affecting the success rate of IVF, the implementation of the above measures can further improve the success rate and bring good news to infertile couples.
