Time cycle of IVF
IVF refers to the combination of sperm and egg in the laboratory to form a fertilized egg, and then transfer the fertilized egg to the mother's uterus for development through assisted reproduction technology. The whole process of IVF includes ovulation, oocyte retrieval, fertilization and embryo development, embryo transfer and pregnancy management. The following will elaborate on the time cycle of IVF from these four aspects.
1. Ovulation guide
Ovulation guidance refers to the promotion of female ovarian ovulation through drugs or other means. In the normal ovulation cycle, only one egg can mature and be discharged. However, test tube babies need multiple mature eggs for egg retrieval, so they need to increase the number of eggs through ovulation guidance. According to the specific situation of women, ovulation guides may need to inject drugs for many times, observe the development of follicles, and artificially control the rupture of follicles at the appropriate time to promote the release of eggs.
The whole cycle of ovulation is usually 10-14 days, and the specific time depends on individual differences and doctors' suggestions
2. Egg taking
Ovulation refers to the removal of mature eggs from the ovary through surgery after ovulation. Egg retrieval is generally carried out 36 to 48 hours after the release of eggs. Through transvaginal ultrasound guidance, thin tubes with aspirators are introduced into the ovary to extract eggs. This process usually requires local or general anesthesia, and the operation time is relatively short, but it needs to be observed for a period of time after the operation to ensure that there are no complications.
The whole process of egg retrieval usually lasts for 1-2 hours, and needs to rest for 1-2 days after egg retrieval.
3. Fertilization and embryonic development
After the egg is taken, the egg is combined with the sperm to form a fertilized egg. After fertilization, the fertilized egg enters the culture dish in the laboratory for embryonic development. The professional technicians in the laboratory will regularly observe the development of embryos and evaluate the quality and feasibility of embryos. Generally, after 2-5 days of embryo development, it will reach its best state and be ready for embryo transfer.
The time cycle of embryonic development can vary according to the specific situation, about 2-5 days.
4. Embryo transfer and pregnancy management
After the embryo develops to its best state, the doctor will select the highest quality embryo and transplant it into the female uterus. Embryo transfer is a simple and painless process, which can be carried out through vagina or laparoscope. After transplantation, women need to continue to receive progesterone and other drugs to increase the probability of implantation. In case of implantation and pregnancy, women need to follow the doctor's advice for pregnancy management.
The whole process of embryo transfer and pregnancy management usually requires at least 2 weeks of observation and rest.
Postoperative recovery time
After IVF operation, women need to take adequate rest to avoid strenuous exercise and fatigue. Generally, the first day after surgery requires bed rest to avoid standing and walking for a long time. Within one week after the operation, women should pay attention to keeping their vagina clean, avoiding sexual life and herbal fumigation. Within 2 weeks after the operation, women need to follow the doctor's instructions and begin to gradually resume their normal life and work.
At the same time, for successfully transplanted test tube babies, women should pay attention to following the doctor's pregnancy management recommendations, including regular prenatal examination, nutrition supplementation, reasonable life arrangement and avoidance of harmful substances.
The specific length of postoperative rehabilitation depends on individual differences and doctor's recommendations, usually several weeks to several months.
summary
The time cycle of IVF includes ovulation guidance, egg retrieval, fertilization and embryo development, embryo transfer and pregnancy management. The whole process needs to be completed with the help of advanced medical equipment and professional teams, and each link needs to ensure the safety and comfort of patients. The length of postoperative rehabilitation varies according to individual differences, and women need to have a full rest and follow the doctor's guidance. Through IVF technology, many couples have realized their desire to have children, bringing hope and happiness to more people.
