Success rate of IVF
As an assisted reproductive technology, IVF has made remarkable achievements in solving the problem of infertility. However, the success rate of IVF is not 100%, which is affected by many factors. These factors include women's age, suffering from other diseases, personal living habits and doctors' experience. Through scientific operation and progress in medical technology, the success rate of IVF is gradually improving.
First, age is an important factor affecting the success rate of IVF. Female fertility will decline with the increase of age. The success rate of IVF is relatively high among young women under 35 years old. However, with the growth of age, the number and quality of female eggs will gradually decrease, thus reducing the chance of successful pregnancy. Therefore, for older women, the success rate of IVF may be lower, and more attempts and patience are needed.
Secondly, suffering from other diseases will also affect the success rate of IVF. Some common diseases, such as polycystic ovary syndrome and endometriosis, will affect women's reproductive health and lead to difficult pregnancy. In this case, targeted treatment is needed to improve the success rate of IVF. In addition, men may also have chromosome abnormalities, poor semen quality and other problems, which will also reduce the success rate of IVF. Therefore, before deciding to carry out IVF, it is necessary to conduct a comprehensive health examination for both husband and wife.
In addition, personal lifestyle is also a key factor affecting the success rate of IVF. Bad living habits such as smoking and drinking will have a negative impact on the reproductive system, thus reducing the chance of pregnancy. Therefore, before preparing for IVF treatment, both women and men need to quit smoking and drinking, and maintain good living habits, including healthy diet and appropriate exercise, to improve the success rate of IVF.
How long does the IVF cycle take?
The length of IVF cycles varies from individual to individual, but usually requires multiple steps and cycles. Generally speaking, the IVF cycle includes the following main steps: ovulation guidance, egg collection, fertilization and embryo extension, embryo implantation and pregnancy detection. The whole process may take several months.
First, ovulation is the first step in the IVF cycle, which aims to generate multiple eggs from the ovary. Doctors will formulate corresponding treatment plans according to women's menstrual cycle and personal conditions. This step usually takes about 10 days to 2 weeks, and the specific time varies from individual to individual.
The next step is egg collection. This step is usually performed within 36 hours after ovulation. Through ultrasound guidance and fine needle technology, doctors will remove mature eggs from the ovary. Egg collection is a simple operation, usually completed within 30 minutes.
After egg collection, eggs and sperm are fertilized in vitro to form embryos. Then the embryos will continue to be cultured and extended in the laboratory, which usually takes 2-6 days. After the embryo extension, the doctor will select the embryo with the most development potential and implant it into the woman's uterus. This step is usually very short, but requires the doctor's accurate operation.
Finally, pregnancy test. About two weeks after embryo implantation, the doctor will conduct blood or urine tests to determine whether the pregnancy is successful. If the pregnancy test result is positive, congratulations to both the husband and wife for successfully realizing their IVF dream. If the pregnancy test result is negative, the IVF cycle needs to be repeated.
summary
As an assisted reproductive technology, the success rate and cycle time of IVF are different due to various factors. Age, other diseases, personal living habits, etc. will affect the success rate of IVF. The cycle of IVF usually takes several months, including ovulation guidance, egg collection, embryo extension, embryo implantation and pregnancy detection. However, with the continuous progress of science and technology and the rich experience of doctors, the success rate of IVF is gradually increasing, providing fertility opportunities for infertile couples.
