How long does IVF need to succeed?
The development of IVF technology provides many infertile couples with the opportunity to realize their reproductive dreams. However, the success of IVF is not achieved overnight, which requires a series of processes and time. This article will elaborate on the success time of IVF from different aspects.
Preparation phase
Before IVF, couples need to undergo a series of medical examinations and evaluations to determine whether it is suitable for IVF. This preparation phase usually takes two to three months.
First, the doctor will conduct a comprehensive physical examination of the couple to understand their physical condition, reproductive system functions, etc. Next, couples need to carry out gene testing to exclude possible genetic diseases or gene mutations. In addition, the doctor will develop personalized treatment plans according to the woman's menstrual cycle and ovulation.
The time of the whole preparation phase may vary according to the specific situation, but after completing all the examinations and assessments, the couple can enter the next phase, that is, the implementation of IVF technology.
IVF process
The process of IVF mainly includes the following steps: ovulation induction, egg retrieval, fertilization and embryo transfer.
First, by using ovulation promoting drugs, doctors can stimulate women's ovulation and multiple pregnancy opportunities. This process usually takes 10 to 12 days.
Next, under the guidance of transvaginal ultrasound, doctors will conduct follicle puncture at the ovulation window to obtain eggs. During the collection process, doctors will monitor ultrasound to determine the exact time, so as to successfully obtain eggs.
Then, the obtained eggs will be fertilized in vitro with sperm in the laboratory. Normally, doctors will choose the healthiest and most active sperm to combine with eggs. This process lasts for 2 to 5 days to determine whether a fully developed embryo is formed.
Finally, the doctor will select the best embryo and implant it into the woman's uterus, hoping that it can be successfully implanted and develop into a healthy fetus.
Success rate and time
The success rate of IVF is closely related to the couple's age, basic health status, birth history and other factors. Generally speaking, young, healthy couples have a higher chance of success.
According to the data provided by some famous IVF hospitals in the world, after a complete IVF cycle, the probability of success is usually between 30% and 40%. However, not all IVF babies succeed on their first attempt. Many couples need to try many times, even several cycles, to get pregnant successfully.
According to individual conditions, the doctor will make the most targeted treatment plan according to the specific situation of the couple. After each cycle fails, the doctor will adjust the treatment plan according to the failure reason and situation to improve the success rate of the next cycle.
summary
The success of IVF is not achieved overnight. It can only be achieved through the preparation stage, IVF process and multiple cycles of attempts. The time of success varies according to individual circumstances, but generally, the success rate of multiple attempts is between 30% and 40%. Couples should be patient and confident, and actively cooperate with doctors' guidance and treatment to increase the possibility of IVF success.
