Fertility problems after successful IVF
The successful application of IVF technology has brought hope to those couples who are unable to conceive naturally or have fertility problems. However, once couples successfully give birth to a healthy baby through IVF technology, they may face some special fertility problems. In the following, we will elaborate on the fertility of IVF from the survival rate of transferred embryos, the possibility of re pregnancy, uterine health and genetic problems.
1. Survival rate of transferred embryos
The most critical step in IVF technology is to transfer the fertilized egg back to the mother's uterus, which is crucial to the survival rate of the embryo. Research shows that the success rate of embryo transfer is usually between 30% and 40%. However, the success rate varies from hospital to hospital and from doctor to doctor. Some world-famous IVF centers, such as Boston Town Hospital in the United States, have a success rate of more than 50%.
There are many reasons for the failure of embryo transfer, such as insufficient thickness of endometrium, endometriosis, poor embryo quality, etc. After the success of IVF, it is necessary to regularly go to the hospital for uterine health examination to ensure that the state of endometrium is suitable for embryo implantation.
In addition, age is also an important factor affecting the survival rate of embryo transfer. The older the female, the lower the success rate of embryo transfer. Therefore, if couples want to become pregnant again after the success of IVF, it is better to have a second transplantation when they are young.
2. Possibility of pregnancy again
After the success of IVF, couples usually consider the possibility of pregnancy again. If the IVF technology is successful once, the possibility of pregnancy again is relatively high. In fact, some studies have shown that after a successful IVF technology, the probability of a second natural pregnancy is twice that of the average couple.
However, not all couples with successful IVF are able to conceive again. Some couples may not be able to conceive naturally due to reproductive system problems, while others may face the challenge of conducting IVF technology again. In addition, the success of IVF once does not mean that it will succeed every time, and the success rate still depends on many factors.
3. Uterine health
After the success of IVF, couples need to pay special attention to uterine health. Uterine health is crucial for embryo implantation and healthy baby birth. Some couples may have uterine problems before IVF, such as endometriosis, hysteromyoma, etc. These problems may continue or worsen after a successful birth.
Therefore, couples should have regular uterine examinations to ensure that the uterus is in good health. Some hospitals provide special uterine examination items, such as hysteroscopy, B-ultrasound, etc., to help couples keep their uterus healthy.
4. Genetic problems
After the success of IVF, couples may face genetic problems. IVF technology usually includes artificial fertilization and embryo gene screening to ensure that the baby has no congenital genetic diseases. However, some genetic diseases may not be detected through gene screening.
In addition, the success of IVF is related to the quality of embryos, and the quality of embryos is related to the quality of fertilized eggs. The quality of fertilized eggs may be affected by the genetic factors of parents, so some genetic diseases may be passed on to the next generation in IVF.
summary
The fertility problems after the success of IVF include the survival rate of transferred embryos, the possibility of re pregnancy, uterine health and genetic problems. Couples should have regular examinations after the success of IVF to maintain good uterine health and pay attention to genetic problems. Although IVF technology has brought hope to couples who cannot conceive naturally, they still need to recognize the existence of fertility problems and work closely with professional doctors to achieve better fertility results.
