When it comes to IVF technology, I believe that many people have a certain understanding of it, but many infertility patients wonder why some people do IVF once successfully, and some people do it two or three times before they succeed. What factors are associated with IVF success rates? Below, Hengjian Overseas will take you to understand this problem.
Why does IVF succeed at once, and what factors are involved in the success rate?
age
Domestic and foreign literature reports that age 25-34 years old has the highest success rate, and age is an important factor in the success of IVF technology, which can reach 45%. After the age of 35, the success rate is about 30%, and the victory rate of more than 40 years old is about 20%, and the live birth rate is significantly reduced, and the impact on eugenics is also greater. Ivy is generally not treated with their own eggs when over 45 years of age, as the winning rate is extremely low and the embryo's chromosomes are prone to abnormalities. The abortion rate in the elderly population in IVF treatment is greatly increased, and premature births and stillbirths are also higher than in young pregnant women.
Causes of infertility in patients
Severe endometriosis with severe uterine malformations Patients with polycystic ovary syndrome do not get sperm from the testicles of severely hypospermia, azoospermia, and age primary infertility. Or there are a large number of deformities, egg deformities or abnormal development, etc., ivory infant treatment is also a high failure rate
chromosome
Some couples have normal variants of chromosomes. These are couples with chromosomal problems, some with primary infertility or a history of adverse pregnancy. Although conceivable through IVF techniques, the rate of failure and miscarriage is higher.
Intrauterine environment
The endometrium secretes a special sugar molecule, and the endometrium is the most important place for the embryo to implant, causing damage to the endometrium, myomyosis, endometritis, endometrial polyps or other lesions of the endometrium that may cause the embryo to fail to implant and affect the success rate. New findings. When this sugar molecule is deficient, the fertility rate is greatly reduced. It is believed that in the near future, medical scientists will overcome this problem and improve the pregnancy victory rate. Embryo quality
No fertilization or fertilization without cleavage can complete the embryo transfer when there is a problem with the sperm or egg. Excellent embryos are victorious
Important conditions. According to the six-level grading method of embryos: fresh embryos I- IV. are all for transfer, and I. II. is excellent embryos. At present, excellent embryos are only morphological classifications, and the potential of embryos cannot be understood. Embryology is now working on a more advanced embryo assessment method, hoping to predict the probability of conception of embryos. But excellent embryos also need a good uterine environment, good endocrine conditions, and superb embryo transfer techniques from doctors. Couples of normal childbearing age share sex at the same time for 1 month, and the chance of pregnancy is only about 20%. So I hope to have a good mindset during treatment, which is also an important factor in victory.
Hengjian Overseas Tip: Why does IVF have success at one time, and what factors are related to the success rate? The above is the introduction of success factors, I hope to be ready to do ivy tubes or are doing IVF you are helpful, in addition, it is recommended that infertile patients need to do a good job of physical examination before doing IVF, and then make adjustments according to the results of the test and their own condition.
