Concept and development of IVF
IVF refers to the birth mode of babies conceived in the process of in vitro fertilization and embryo transfer. IVF technology originated in the 1950s. After decades of development, it has become an effective means to solve the problem of infertility. Under normal circumstances, how many days does a complete IVF cycle take? The following will introduce each stage of egg taking, fertilization, embryo cultivation and transplantation in detail.
Time of egg retrieval stage
The first stage in the IVF program is the egg retrieval stage. Some preparations, such as ovulation guide and endometrium preparation, are usually required for egg retrieval. The duration of this process varies from person to person, and generally requires about 10 to 14 days of treatment. During treatment, patients need to inject hormones every day to promote ovarian development and produce multiple follicles. When the follicle matures, the doctor will take the egg in the operating room. The whole procedure usually lasts from 30 minutes to 1 hour.
After taking eggs, the eggs will be sent to the laboratory for subsequent operations. The hospital usually provides a comfortable environment, where the eggs will be stored in an appropriate medium for fertilization.
Time of fertilization and embryo cultivation
Fertilization is the next step in the IVF process. Normally, sperm and egg will combine in vitro, and laboratory staff will conduct fertilization. This process takes about 4-6 hours. After successful fertilization, the fertilized egg will be further cultivated into an embryo.
The embryo cultivation stage is one of the key steps. In the laboratory, embryos will be placed in petri dishes and cultured under specific temperature and gas conditions. At this stage, the development of the embryo will be closely monitored. Normally, embryos will be cultured in the laboratory for 2 to 6 days. Depending on the situation, doctors will decide when to carry out embryo transfer.
Time of embryo transfer stage
Embryo transfer is the last and one of the most critical steps in the IVF program. The transfer is usually carried out on the third or fifth day of embryo cultivation, depending on the development of the embryo and the doctor's advice. The whole embryo transfer process usually takes only a few minutes to complete.
After that, the patient needs to rest for a period of time to ensure the successful implantation of the embryo into the endometrium. Doctors may advise patients to continue taking some hormone drugs to promote embryo implantation and growth. Usually, patients need to wait about 10 to 14 days, and then take a blood test to determine whether they are pregnant.
summary
In conclusion, the time required for a complete cycle of IVF can be divided into egg retrieval stage, fertilization and embryo cultivation stage, embryo transfer stage and pregnancy confirmation time. It usually takes 10 to 14 days to get eggs, about 2 to 6 days for fertilization and embryo cultivation, and only a few minutes for embryo transfer. Pregnancy confirmation is usually 10 to 14 days after embryo transfer. The whole cycle takes about 3 to 4 weeks to get results.
Different hospitals and doctors may have slightly different arrangements and schedules, but the above is a general reference. The IVF procedure requires close cooperation between patients and doctors to ensure the smooth progress of each stage and achieve the best results.
