Fertility cycle of IVF
IVF refers to the process of applying human IVF and embryo culture technology to infertile couples and obtaining pregnancy through artificial assisted reproduction technology. The birth cycle of test tube babies varies with individual differences and hospital processes, generally including the following stages.
Phase I: preliminary assessment and preparation
The first stage is preliminary assessment and preparation. Infertile couples first need to go to a specialized hospital for detailed examination and evaluation to understand the causes of infertility and determine whether IVF is suitable. The duration of this phase varies according to the individual situation and the schedule of the hospital. It takes about 1-2 months.
After the preliminary assessment, the doctor will develop a personalized treatment plan according to the couple's situation. This may include adjusting living habits and diet, combined with some auxiliary treatment, such as the use of ovulation promoting drugs. This phase usually takes 3-6 months to ensure optimal physical condition.
After the preliminary assessment and preparation phase, the couple can enter the next phase - the implementation of assisted reproductive technology.
Phase II: Implementation of assisted reproductive technology
The second stage is the implementation of assisted reproductive technology. This stage includes the following processes: ovarian measurement, ovarian stimulation, egg collection, sperm collection, in vitro fertilization, embryo culture and embryo transfer.
Ovarian stimulation is to inject ovulation promoting drugs to women to increase the number and quality of follicles. This process lasts about 10-12 days, followed by egg collection. Egg collection needs to be carried out in the operating room, and the number of eggs in the follicle is monitored by puncture.
At the same time, the man needs to provide sperm samples. Semen can be obtained by natural ejaculation, semen collector or sperm thawing. After sperm collection, laboratory technicians will combine it with eggs for in vitro fertilization, and then put the fertilized eggs into a petri dish for embryo culture. Embryo culture usually takes 3-5 days.
The last step is embryo transfer. The doctor will transplant the healthiest one or two of the multiple embryos back to the uterine cavity of the woman. The whole implementation phase of assisted reproductive technology usually takes 2-3 weeks.
Stage 3: Embryo implantation and pre pregnancy maintenance
The third stage includes embryo implantation and pre pregnancy maintenance. Embryo implantation refers to the process in which the fertilized egg is embedded into the endometrium, which generally occurs 6-10 days after embryo transfer. Next, women need to take some routine pre pregnancy maintenance measures, including rest, diet conditioning, and avoiding exposure to some harmful substances. This phase usually takes 1-2 weeks.
Stage 4: Pregnancy and pregnancy
Once the embryo is successfully implanted, the woman is in the gestation and pregnancy period. At this time, the couple needs to go to the hospital regularly for prenatal inspection and follow-up to ensure the safety of mother and baby. The duration of pregnancy varies from individual to individual, generally around 40 weeks.
In general, the birth cycle of IVF includes preliminary assessment and preparation, implementation of assisted reproductive technology, embryo implantation and pre pregnancy maintenance, and pregnancy and gestation period. The whole process requires patience and persistence, and close cooperation and cooperation with doctors. Although the time of each stage varies with individual differences and hospital processes, it usually takes 6 months to 1 year.
Summary
The reproductive cycle of IVF can be roughly divided into four stages: preliminary assessment and preparation, implementation of assisted reproductive technology, embryo implantation and pre pregnancy maintenance, and pregnancy and gestation. The whole process usually takes 6 months to 1 year, and individual differences and hospital processes will lead to time changes. No matter how long the process is, couples need to communicate closely with doctors and cooperate actively, so as to increase the probability of success of IVF.
