What is the time limit of IVF
IVF is an assisted reproductive technology that helps couples who cannot conceive naturally realize their reproductive dreams through in vitro fertilization and embryo transfer. However, IVF is not a process that can be carried out anytime, anywhere, but has certain time limits. The time limit of IVF will be elaborated from several aspects.
Time limit of female age on IVF
The fertility of women gradually decreases with age, so there is a certain age limit for IVF. Generally speaking, female fertility peaked between the ages of 30 and 35, and then began to decline gradually. Therefore, doctors generally recommend that women perform IVF surgery before the age of 35 to ensure a higher success rate. However, age is not an absolute limit, and some hospitals will also consider some exceptions under special circumstances.
In addition, women also need to undergo a series of physical examinations, including endocrine system, uterus, ovary and other examinations, to determine whether it is suitable for IVF surgery. These inspections also need some time.
Time limit of embryo quality on IVF
The success of IVF is closely related to the quality of embryos. After in vitro fertilization, doctors will choose the best embryo for implantation, and in some cases, they may choose to freeze the embryo. However, the quality of frozen embryos will decline over time, so the time of embryo implantation is also limited.
At present, a technology called fixed embryo biomarker (EEVA) can help doctors better select the best embryo. This technique can evaluate the quality of embryos, thus improving the success rate of IVF.
Time limit of cycle regulation on IVF
IVF surgery requires periodic regulation to ensure the best pregnancy effect. Cycle regulation generally includes ovulation guidance and endometrial preparation. Ovulation guides need drugs to help follicular development and ovulation, and endometrial preparation needs to ensure the good condition of endometrium.
The whole cycle regulation generally takes 2 to 4 weeks, and the specific time will be adjusted according to the patient's situation. Therefore, IVF surgery can not be carried out at any time and needs to be prepared for a period of time.
Time limit of hospital arrangement and resources on IVF
IVF surgery needs to be carried out with the help of hospitals, so hospital arrangements and resources will also have an impact on time constraints. Some busy hospitals may need to wait for some time, and patients may need to make an appointment in advance.
In addition, the equipment, technology and the level of the doctor team in the hospital will also affect the time limit of IVF. Some hospitals may have outdated equipment and low technical level, resulting in long operation time or low success rate. Therefore, the key to the success of IVF is to choose a regular hospital with advanced equipment and high technology.
To sum up, the time limit of IVF mainly includes female age, embryo quality, cycle regulation, hospital arrangement and resources. Understanding these time limits is very important for couples to choose the right time for IVF surgery. Only when the IVF operation is carried out at the right time can the success rate be improved and the birth dream be realized.
