If the test tube is not successful once, do it twice, three times, four or five times or six times... This may be a matter of course for many people. So, how many times can the test tube be done, and if it is not successful, can it be done forever?
Is there a limit to the number of times IVF can be performed?
Theoretically, there is no fixed number of IVF, for example, some women do IVF eight or nine times, in fact, as long as the physical condition is good, and meet the conditions of IVF, it can be done until it is successful.
In the next test tube, it is best to have frozen embryos, such as patients without stored frozen embryos, who need to perform ovulation induction, embryo culture and other steps again, that is, to start over, and the cost is the same as the last time.
*Recommendation: The interval between the second tube and the previous tube is preferably about half a year. Therefore, it is very important to maintain the body before each test tube into the week.
Relationship between IVF success rate and number of fertility assistance
In fact, simply increasing the number of cycles to improve the success rate of test tubes can not be achieved, there is no direct correlation between the two, and there is no superposition relationship.
So why do so many people successfully get pregnant through multiple IVF cycles?
The main reasons are:
get good embryos (such as sacs);
With good pregnancy conditions (find the cause from the last failure and get solved).
In general, ivy women who try 3 cycles still fail, it is not recommended to continue to try on their own.
Why is it no longer recommended to do it after three test tubes?
Economic pressures have increased
The cost of an IVF is at least twenty or thirty thousand, and there is a higher, if one is not successful, the next two or three times, not only require a lot of energy, but also need a lot of financial resources, many couples do the third time, they have been powerless, they want to give up.
Women's physical endurance
Although IVF is high-tech and can help us conceive, it is not the more the better, but if the number of times, such as eight or nine times or even more, will increase psychological stress, confidence is reduced, then the female body will not be able to bear, it will affect physical and mental health.
Test tube age requirements
Although it can be done as long as the patient is a woman of childbearing age, in order to improve the success rate, it is best to be within the age of 40, and some hospitals for older people over 40 years old do not accept it.
Reasons for the low success rate of test tubes in older women:
Poor egg quality can lead to poor embryo quality;
Older women will also have a significant decline in reproductive ability, and the pregnancy environment will be inferior to that of younger women.
