What is the success rate of IVF? At present, IVF technology has become a mature professional medical service technology in clinic, which also brings hope to many couples who can't get pregnant normally. Let's take you to know how high the success rate of IVF is at present.
What is the success rate of IVF? 1 If both men and women have no diseases, under normal circumstances, the possibility of pregnancy every month is only 10%. If both men and women have diseases, the success rate is only about 1%. At present, the single success rate of IVF technology has increased to about 40%, which has far exceeded the limit of human beings. But IVF is a science after all, and it is impossible to achieve a success rate of 100%. At present, the success rate of the best foreign IVF center can only reach 50%. The success rate of "test tube" babies depends on many aspects, including endocrine and laboratory conditions, the technical level of technicians, the age of patients, the condition of uterus and ovaries, and whether there are other diseases. Among them, the age of the woman is the most significant. The success rate of female "test-tube" babies aged 25-35 is higher than the average level of 30%-40%, and some can reach 50% or even higher. However, after the age of 35, the success rate gradually decreases, reaching only about 20% at the age of 40, because the quality and quantity of eggs decrease with age. But the success rate of three times can generally reach 80%.
Suitable for test-tube babies
1, serious tubal diseases, such as pelvic inflammatory disease leading to tubal obstruction and hydrops, tubal tuberculosis and normal endometrium, tubal obstruction and hypoplasia after ectopic pregnancy, tubal ligation, ectopic pregnancy and other bilateral salpingectomy.
2. Endometriosis and adenomyosis.
3. Immune infertility, such as anti-sperm antibody and anti-endometrial antibody.
4. Male factors, namely oligozoospermia, asthenospermia and teratospermia.
5, unexplained infertility.
6, other reasons infertility treatment is invalid.
7. Those with genetic diseases need to be diagnosed before transplantation.
8. Others: such as unruptured follicle syndrome.
What is the success rate of IVF? The success rate of IVF is mainly affected by the age, chromosome, intrauterine environment, infertility symptoms, excellent embryo rate and psychological state of the patient.
1, the physical factor of the operator. Physical factors can be subdivided into four aspects: age, chromosome, intrauterine environment and infertility symptoms.
(1) age.
Age is an important factor affecting the success rate of IVF, and it is also the embodiment of a normal and vigorous female reproductive system. With the increase of age, the number and quality of eggs decrease, the fertilization rate decreases, the pregnancy rate decreases obviously and the abortion rate increases. According to research, the pregnancy rate of couples of childbearing age is only 20%. After women reach the age of 35, all the functions of the body will decline, especially the reproductive system. Domestic and foreign literature reports that the success rate of IVF surgery is the highest at the age of 25-34. After the age of 35, the success rate will drop significantly, and over 40, the success rate will be around 20%, and the live birth rate will drop significantly, which will also have a great impact on eugenics.
You can't treat IVF with your own eggs over 45 years old, because the success rate is extremely low and the chromosome of the embryo is prone to abnormality. The abortion rate of middle-aged and elderly people in IVF treatment has greatly increased, and the premature delivery and stillbirth are also higher than those of young pregnant women.
(2) chromosome.
In some couples who are infertile or have a bad pregnancy history, if the couple's chromosomes have normal variation, although they can be conceived by IVF technology, the failure rate and abortion rate are high.
(3) intrauterine environment.
For example, endometrial polyps, endometritis, previous surgery or inflammation (tuberculosis is the most common) can all affect embryo implantation, thus leading to the failure of IVF surgery.
(4) Infertility symptoms of patients
Elderly patients with primary infertility, endometriosis and polycystic ovary syndrome with severe uterine malformation, patients with severe oligozoospermia and azoospermia, whose testicles can not obtain sperm, or have a large number of abnormal sperm, abnormal eggs or abnormal development, etc. There is also a high failure rate in the treatment of IVF.
2. Excellent embryo rate
When sperm and eggs have problems, embryo transfer cannot be completed without fertilization or fertilization and cleavage. Excellent embryos are an important condition for success. However, excellent embryos also need a good uterine environment, good endocrine conditions, and superb embryo transfer technology of doctors.
According to ovulation time 1 month, the probability of pregnancy is only about 20%. Therefore, we hope to have a good attitude during the treatment, which is also an important factor for success. Therefore, the factors of excellent embryo rate are closely related to the physical factors of the operator. According to the current medical technology, it can be said that the physical condition of couples receiving artificial insemination determines the success rate of excellent embryos.
3. Psychological factors.
Many data show that the patient's psychological and mental state is an important factor affecting the success or failure of IVF treatment. Experts believe that the endocrine of women with great psychological pressure will be affected, and the blood vessels will be in a state of contraction for a long time, which will affect the local blood flow of uterus and ovary. Moreover, the nervous system tension will cause the abnormal release of some nerve mediators, which will lead to the disorder of muscle contraction of uterus and fallopian tube, thus leading to the failure of treatment. Therefore, it is very important to relieve psychological pressure, communicate between doctors and patients, and understand and encourage each other between husband and wife.
What is the success rate of IVF? 3 Is IVF good?
Under normal circumstances, it is a very festive thing for a couple to give birth to twins, so that many infertile couples require doctors to implant at least two embryos when doing IVF technology, and they want to have an extra child through IVF technology. However, the reproductive Commissioner believes that twins and multiple births brought by assisted reproductive technology should be tried as much as possible. In medicine, iatrogenic multiple births are considered as failed assisted reproduction.
Conditions for being an IVF:
1. Requirements for women to be IVF: In order to improve the success rate of IVF transplantation, women need to have a physical examination in the early stage and have relevant physical conditions. The examinations that women need to do are: B-ultrasound (uterus, appendix), leucorrhea examination, blood test (chromosome analysis, anti-sperm antibody, anticardiolipin antibody, urine routine, blood routine, blood type, coagulation test, biochemistry, hepatitis B, hepatitis C, syphilis specific antibody, HIV antibody).
2. Physical conditions for men to be IVF: The success of IVF transplantation is related to the sperm quality of both husband and wife. If the sperm survival rate is low, it is useless to be a test-tube baby. Necessary tests include: blood test (chromosome test, anti-sperm antibody, urine routine, blood routine, blood type, biochemistry, hepatitis B, hepatitis C, syphilis specific antibody, HIV antibody). If men have asthenospermia, they need to do Y chromosome microdeletion test.
3. Legal document conditions of IVF: One of the conditions of IVF is legal. Infertile couples need marriage certificate, husband and wife ID card and birth certificate as the basis for effective registration before IVF.
4, the cost of doing IVF conditions: the cost of IVF is also a condition that has to be considered, because IVF is a cutting-edge technology, and the corresponding cost will be high. Therefore, it is also very important for infertile couples to consult the relevant expenses and make preparations before doing IVF.
