What is the reason for the test tube not implanting?

The happiest thing for a family is welcoming the arrival of a new life. After learning about the pregnancy, both the parents and the elders were very happy. In addition, there are many other factors in real life that affect the success rate of IVF, such as what to pay attention to during the IVF process, what foods are good for the body, what foods should not be eaten, and so on. What is the reason why the test tube does not implant?

1. Age: The age of the woman plays a vital role in the issue of fertility. Generally speaking, even if the man is in his 50s or 60s, the impact on fertility is not obvious, but it is not the case for the woman. As the woman ages, her fertility will gradually decline, and the decline will accelerate significantly after the age of 35. After menopause, it will be completely lost, and this process is irreversible. At present, there is no drug that can make women's fertility "rejuvenate".

2. Uterine function: For patients with severe endometrial damage, if the endometrial thickness is less than 7 mm during the superovulation cycle, the pregnancy rate is low and the miscarriage rate is high during IVF. There is currently no reliable treatment method. In addition, although uterine malformation does not affect the pregnancy rate of IVF, the miscarriage rate and premature birth rate are high, and the live birth rate is low. Therefore, it is best to perform corrective surgery before IVF, so as to improve the pregnancy prognosis and increase the IVF pregnancy rate.

3. Ovarian function: Ovarian function refers to the responsiveness of the ovaries to ovulation-inducing drugs. The worse the ovarian function, the fewer eggs are obtained, the worse the quality of the eggs, the lower the pregnancy rate and the higher the miscarriage rate. Ovarian function is not only related to age, but also to individual differences. In addition, ovarian surgery, especially ovarian cystectomy and ovarian electrocoagulation, can seriously damage the ovarian structure and damage the ovarian function. Therefore, non-pregnant young women should avoid ovarian cystectomy as much as possible. If it is really necessary, as much ovarian tissue should be retained as much as possible, and oophorectomy should be avoided.

4. Hydrosalpinx: Hydrosalpinx is also an important cause of infertility. At the same time, if patients with hydrosalpinx want to have a test-tube baby, their pregnancy rate is also lower than those without hydrosalpinx, and the incidence of miscarriage and ectopic pregnancy will be greatly increased. Therefore, before such patients use the test-tube baby technology, they should first ask obstetricians and gynecologists to perform the removal or proximal ligation of the hydrosalpinx fallopian tube surgery, so as to improve the pregnancy rate of test-tube babies.

5. Technical factors: including ovulation induction program, ovulation-promoting drugs, laboratory quality control, embryo culture medium type, technical operation proficiency, material quality, instrument stability and other factors. A targeted and scientific ovulation induction program is crucial, which is the basis for success. At the same time, the use of ovulation induction drugs also has its own knowledge. It is not necessary to import ovulation induction drugs to be effective. The key is to suit the characteristics of Chinese women.
