What is the probability of success of IVF?
In Vitro Fertilization - Embryo Transfer (IVF-ET) is a kind of assisted reproductive technology, which is used to help couples who cannot conceive naturally achieve their reproductive aspirations. However, the success rate of IVF is not fixed and will be affected by many factors.
First, female age is one of the important factors affecting the success rate of IVF. Women's chances of having children over the age of 35 are gradually reduced, because the number and quality of women's eggs will decline with age. According to statistics, the success rate of IVF for women under 35 years old is usually between 40% and 60%, while that for women over 40 years old is significantly reduced, only 20% to 30%.
Secondly, the quality of male sperm will also affect the success rate of IVF. Sperm quantity, motility and abnormal rate of morphology are all important indicators affecting sperm quality. If men have sperm quality problems, the success rate of IVF will often be reduced. It should be pointed out that the success rate of sperm acquisition can be improved by selecting appropriate treatment methods, such as minimally invasive sperm extraction (Micro TEST), so as to improve the success rate of IVF.
In addition, the condition of women's uterus and the diseases they suffer from will also affect the success rate of IVF. If women have uterine malformations, adenomyosis and other problems, or suffer from endometriosis, polycystic ovary syndrome and other diseases, the success rate of IVF is often reduced. For these cases, doctors may need to improve the uterine condition through surgery or drug treatment to increase the probability of success.
Is the success rate of IVF related to method selection?
The success rate of IVF is closely related to the choice of methods. At present, common IVF technologies include traditional IVF, minimally invasive IVF and preimplantation genetic diagnosis (PGD).
The traditional test tube baby refers to the method of fertilizing eggs and sperm in vitro in a culture dish, cultivating embryos and then transplanting them back to the female uterus. This method is suitable for a variety of infertility symptoms and has a high success rate. According to different patient conditions, doctors will choose to use hormone to promote ovulation, follicle puncture or embryo culture stage for appropriate adjustment, so as to improve the success rate.
Compared with traditional test tube babies, minimally invasive test tube babies pay more attention to fine manipulation and personalized treatment. This method usually includes minimally invasive sperm extraction, intracytoplasmic sperm injection (ICSI) and other technologies. Minimally invasive IVF can not only improve the success rate of obtaining sperm quality, but also reduce the trauma to women and increase the success rate of IVF.
PGD refers to genetic diagnosis of embryos before implantation, screening for specific genetic diseases and chromosomal abnormalities. PGD can help the carriers of genetic diseases to avoid passing the disease on to their offspring and improve the success rate of IVF. By choosing the treatment scheme under different circumstances, doctors can improve the success rate of IVF according to the specific conditions of patients.
Other influencing factors of IVF
In addition to age, sperm quality, uterine condition and method selection, the success rate of IVF will be affected by other factors.
The health status of patients is one of the important factors that affect the success rate of IVF. Some chronic diseases, immune system problems or metabolic syndrome can reduce the success rate of IVF. Therefore, before IVF, patients need to receive a comprehensive physical examination to ensure that their health meets the requirements.
The success rate of IVF is also related to the technical level and equipment conditions of the hospital. A first-class medical institution usually has advanced equipment and an experienced team of doctors, which can provide better treatment effect and success probability.
conclusion
To sum up, the success rate of IVF is determined by a variety of factors, including female age, male sperm quality, uterine condition, disease, method selection, physical health and hospital technical level. Patients can consult with professional doctors to choose a treatment scheme suitable for them, so as to improve the success rate of IVF and achieve a better fertility desire.
