Recently, there have been many good news from older stars. For example, Andy Lau, 54, and Zhu Liqian, 50, successfully gave birth to a second child through several years of regular artificial pregnancy. The 45-year-old actress Zhang Ting also said that she had suffered from infertility and had only two children after 10 IVF sessions.
In fact, there are indeed many older women among the beneficiaries of IVF technology, so can we really work or live at ease and wait until we are 45 or even 50 years old before giving birth through IVF?
The older the age, the lower the success rate of IVF.
Younger women ovulate once a month, but as they get older, ovulation will become more and more irregular, so it is relatively difficult for older women to get suitable eggs for IVF.
The older the pregnant woman is, the more the infant malformation rate will double, because the quality of the egg will also deteriorate with age, and the fetus may suffer from congenital diseases such as [Down’s syndrome] when it is in the mother’s belly.
- The success rate of IVF for women over 40 years old is only about 30% of that for women under 35 years old. Once a woman is over 45 years old, the success rate of IVF is even less than 10%.
Therefore, age is a very important factor. The older the age, the lower the success rate of IVF.
Even if it succeeds, there is still a greater risk.
Even if the baby is successfully conceived through IVF, the older the pregnant woman is, the higher the probability of pregnancy hypertension, pregnancy diabetes, etc. If these diseases are not well controlled, they will endanger the lives of the pregnant woman and the fetus.
Women over 35 are prone to miscarriage, Usually because the incidence of chromosome abnormalities has become higher, that is to say, even if the embryo is cultivated and transplanted through IVF technology, but the embryo is prone to congenital problems and cannot survive smoothly. According to statistics, women aged 35-45 have a 20% ~ 35% chance of miscarriage, almost equivalent to one in every three people, and this probability is already quite high.
In addition, as women get older, the functions of vagina and uterus will deteriorate and the risk of dystocia will also increase.
How old can a test-tube baby be?
It is best not to be over 45 years old.
For women aged 25 to 35, the success rate of IVF is relatively high, often 40% ~ 50% or higher.
The success rate will gradually decline after the age of 35, and only about 20% at the age of 40.
If a woman is over 45 years old, doctors in the reproductive center will often advise her not to be a test-tube baby, because even if she can conceive, whether the child can stay or not and whether the mother can survive pregnancy safely are big problems.
In short, fertility will decline with age. The examples of stars are only the result of their choices. Those who can have children smoothly in their mid-50s can be regarded as [miracles]. Never imitate them.
I hope everyone can do the right thing at the right time, give birth as early as possible, find infertility and don’t delay, don’t leave regrets for yourself.
