Success rate of IVF
IVF is a kind of assisted reproductive technology, which is used to help couples who cannot conceive naturally realize their reproductive aspirations. Success rate is a concern of many couples. The success rate of IVF is described in the following aspects.
1. Age factor
Female age is one of the important factors affecting the success rate of IVF. Generally speaking, the younger the female, the higher the success rate. This is because when women are young, their eggs are of better quality and their fertility is stronger. Data shows that the success rate of IVF can reach 40% to 50% for women under 35 years old. But in the age group over 40, the success rate will be significantly reduced.
In addition, the influence of male age on the success rate of IVF is relatively small, but it cannot be ignored. The sperm quality of men will decline with age, which may affect the effect of fertilization.
2. Birth history factors
Women's reproductive history also affects the success rate of IVF. If a woman has been pregnant before and successfully gave birth, her success rate of re IVF will be relatively high. This is because the previous fertility experience shows that women's reproductive capacity is normal and the uterine environment is good.
3. Physical condition factors
Physical condition also has an important impact on the success rate of IVF. For example, women with endometriosis, premature ovarian failure, tubal obstruction and other problems will reduce the success rate of IVF. In addition, the weight of women will also affect the success rate of IVF. Too heavy or too light body mass index (BMI) may have adverse effects on the uterine environment, affecting the success rate of IVF.
4. Level of hospitals and doctors
Finally, choosing a formal and professional hospital and experienced doctors for IVF is also one of the important factors to ensure the success rate. The formal hospital is fully equipped, professional team, and has rich clinical experience, which can provide better services and treatment schemes, thus improving the success rate of IVF.
The relationship between the times of egg extraction and the success rate of IVF
In the process of IVF, egg extraction is a key step. There is a certain relationship between the times of egg extraction and the success rate of IVF, which is described in the following aspects.
1. Egg quality
In a test tube baby, the quality of eggs has a great impact on the success rate. With a large number of eggs extracted each time, it will be easier to select high-quality eggs. When the number of eggs is small, it is relatively difficult to select high-quality eggs, which may affect the success rate of IVF.
2. Individual differences
The ovarian response of each woman is different. Some women can get enough eggs of good quality after extracting eggs once, while some women may need to extract eggs several times to get enough eggs. Therefore, individual differences are also an important factor that affects the relationship between the number of oocytes extracted and the success rate of IVF.
3. Treatment strategy
Doctors formulate treatment strategies according to women's physical conditions and ovarian response. For women with better ovarian response, only one egg extraction may be required; For women with poor ovarian response, multiple egg extraction may be required. Therefore, the times of egg extraction and the success rate of IVF are also related to the treatment strategies formulated by doctors.
4. Doctor's experience
Experienced doctors have high proficiency in the operation of egg extraction, and can better grasp the opportunity and method of egg extraction, thus improving the success rate of egg extraction. Therefore, the doctor's experience is also an important factor that affects the relationship between the number of times of egg extraction and the success rate of IVF.
summary
Through the above description, we can draw the following conclusions:
First, women's age is one of the important factors affecting the success rate of IVF. The younger the age, the higher the success rate.
Secondly, women's birth history is one of the factors that affect the success rate of IVF, and women who have had birth experience have a relatively high success rate.
In addition, physical condition and the level of hospital doctors will also affect the success rate of IVF.
There is a certain relationship between the number of times of egg extraction and the success rate of IVF. The relationship between the number of times of egg extraction and the success rate will be affected by egg quality, individual differences, treatment strategies and doctor experience.
Therefore, when deciding to carry out IVF, couples should choose the right time, choose the right hospital and doctor according to their own conditions, and closely cooperate with doctors to treat, so as to improve the success rate of IVF.
