Steps and days of IVF
IVF is an assisted reproductive technology that helps infertile couples realize their reproductive dreams through in vitro fertilization, embryo transfer and other steps. The following details the number of days required for each step of IVF.

1、 In vitro fertilization (IVF)
In vitro fertilization is the first step in the process of IVF. This step involves the extraction of female eggs and male sperm, and then in vitro fertilization in the laboratory. The specific steps are as follows:
1. Adjustment cycle (about 2 weeks): Before in vitro fertilization, women need to take drugs to adjust the ovarian cycle in order to coordinate the preparation of the ovary and endometrium. This process usually takes about 2 weeks.
2. Egg retrieval (about 20 minutes): During egg retrieval, women will receive local anesthesia. Doctors remove multiple eggs by puncturing the ovaries. This process takes about 20 minutes.
3. Sperm extraction (about 1 day): Men provide semen samples, which are processed in the laboratory to obtain high-quality sperm. This process usually takes 1 day.
4. In vitro fertilization (about 1 day): The doctor will combine the obtained sperm with the egg and place it in the culture dish for in vitro fertilization. This process is usually completed within 1 day.
5. Embryo culture (3-5 days): The fertilized eggs will be cultured in the laboratory, which usually takes 3-5 days. During this period, doctors will evaluate the quality of embryos and select the best embryos for transplantation.
2、 Embryo transfer
Embryo transfer is the second and most critical step in the process of IVF. Embryo transfer is usually carried out on the 3-5 days of IVF or 5-6 days of culture.
1. Endometrial preparation (about 2 weeks): Before embryo transfer, women need to take hormone drugs to prepare the endometrium to provide a good environment for embryo implantation. This process usually takes about 2 weeks.
2. Embryo transfer (about 20 minutes): The doctor inserts the selected embryo into the female uterus through a thin tube. This process usually only takes about 20 minutes.
3. Rest (several days): Women need to rest for a period of time to give the embryo a better chance of implantation. This process usually takes several days.
3、 Pregnancy detection and treatment of transplant failure
After embryo transfer, women need to wait about 10-14 days for pregnancy testing. If the test result is positive, it means the IVF treatment is successful and the woman enters the pregnancy stage. If the test result is negative, it means that the treatment is not successful, and the treatment of transplant failure can be considered.
1. Pregnancy test (about 10-14 days): Women will undergo a blood or urine pregnancy test to determine if they are successful. This process usually takes about 10-14 days.
2. Migration failure handling: If IVF treatment is not successful, the couple can discuss the reason with the doctor and decide whether to try IVF again. The doctor may recommend some adjustment or improvement methods to improve the success rate.
4、 Summary
The steps of IVF include in vitro fertilization, embryo transfer, pregnancy detection and treatment of transplant failure. In vitro fertilization and embryo transfer are the key steps in the whole process. The whole IVF process usually takes weeks to months, and the specific time varies with individual differences and hospital operating procedures. When choosing IVF treatment, couples should fully understand the time of each step and the mental and physical preparations required, and work closely with doctors to improve the success rate.
