Test tube baby time cycle
IVF is an assisted reproductive technology. It is a method to achieve fertility by artificially combining sperm and eggs in the laboratory, and then implanting the fertilized eggs into the female uterus. The time cycle of IVF can be described from the following aspects.
1. Diagnosis and preparation stage
Before IVF, doctors will conduct a comprehensive inspection and evaluation of both husband and wife, including the quality of male sperm and female eggs, and the condition of uterus. This process usually takes several months.
In the diagnosis and preparation stage, some special examinations may also be required, such as hormone testing, endometrial biopsy, etc., to ensure that women's physical conditions are suitable for IVF.
At the same time, both husband and wife also need to receive psychological counseling to cope with the physical and mental pressure that IVF may bring.
2. Ovulation promotion and egg retrieval process
The next stage in the IVF cycle is ovulation induction and egg retrieval. This phase usually lasts about 10 to 14 days.
During this period, women will inject or take orally ovulation promoting drugs to increase the probability of ovulation. Doctors will monitor the growth of follicles through ultrasound and other inspection methods.
Once the follicle grows to the proper size, the doctor will take out the egg in the operating room. This process usually uses local anesthesia to puncture the ovary through a needle and extract the eggs.
3. Fertilization and embryo culture
After taking the eggs, the doctor will artificially fertilize the eggs and sperm in the laboratory. There are two methods for this process: conventional fertilization or microinjection. After successful fertilization, the obtained fertilized eggs will be cultured in the laboratory.
The time of embryo culture is usually 3 to 5 days. The doctor will monitor the quality and development of the embryo to select the most promising embryo for implantation.
4. Embryo implantation and pregnancy observation
On the 3rd to 5th day of embryo culture, doctors will implant the most potential embryos into the uterus of women. This process is usually painless and takes only a few minutes to complete.
After implantation, women need to rest for a period of time to allow the embryo to have the opportunity to implant. The doctor will give some supportive drugs to facilitate the implantation process.
The pregnancy observation phase usually requires a waiting period of 12 to 14 days. During this period, women need to carry out HCG testing in blood or urine to determine whether they are successful in pregnancy.
Number of successful IVF attempts
The number of successful attempts of IVF varies according to individual differences and special circumstances. Many factors will affect the success rate of IVF, including the age of women, the quality of eggs and sperm, and the condition of uterus.
According to actual data, the success rate of IVF in the world is about 30% to 40%. This means that there is about a one-third to a quarter chance of a successful pregnancy in one attempt. However, not all attempts can be successful, and some couples need to try many times to get pregnant successfully.
According to the doctor's advice and personal circumstances, the couple can decide the number of attempts. Each attempt will usually have different treatment plans and adjustments to improve the success rate.
Summary
The time cycle of IVF roughly includes diagnosis and preparation stage, ovulation induction and oocyte retrieval process, fertilization and embryo culture, embryo implantation and pregnancy observation. The whole process takes several months, and the duration of each phase is different.
The success rate of IVF is affected by many factors, and the success rate of each attempt is about 30% to 40%. Therefore, some couples may need to make multiple attempts to get pregnant successfully.
However, with the progress of modern medicine and the improvement of technology, IVF has become the dream of many infertile couples. Many IVF hospitals have been set up around the world to provide professional diagnosis, treatment and support for couples.
The most important thing is that no matter how long the time cycle of IVF and how many attempts to succeed, both husband and wife need to adhere to, be patient and confident, and work closely with doctors to jointly pursue the dream of a healthy baby.
