The relationship between ectopic pregnancy and test tube baby
Ectopic pregnancy refers to the implantation and development of fertilized eggs outside the uterus, while IVF is a kind of assisted reproductive technology, which transfers fertilized eggs into the uterus of women through artificial insemination to solve the problem of infertility. Although the two concepts are not directly related, to some extent, IVF may increase the probability of ectopic pregnancy. The following aspects will elaborate on the relationship between them.
1. Physiological factors
In the process of IVF, ovulation promoting drugs are often used to increase the number of female ovulation and the rate of obtaining fertilized eggs. These drugs may lead to prolonged stagnation of eggs in the fallopian tube, increasing the probability of fertilized eggs remaining in the fallopian tube, thus increasing the risk of ectopic pregnancy.
In addition, in the process of IVF, the fertilized egg may cause damage to the fallopian tube to some extent by transplanting it into the uterus. This injury may lead to abnormal fallopian tube function, and the fertilized egg cannot move through the lumen normally, thus increasing the incidence of ectopic pregnancy.
In addition, the endometrium may become weak due to the influence of hormones during IVF, which is not conducive to the implantation of fertilized eggs. When the fertilized egg cannot be successfully implanted in the uterus, there is a high risk that it will be implanted in the fallopian tube and other parts, leading to ectopic pregnancy.
2. Operation factors
In vitro babies need to undergo surgical procedures such as optical tweezers or thin endometrial puncture, which may cause harm to the fallopian tubes. Inflammation, blockage or adhesion of fallopian tubes caused by operation will increase the risk of ectopic pregnancy. Therefore, the key to reduce the risk of ectopic pregnancy is the operation skills in the process of operation and the selection of formal hospitals.
3. Age factor
With the growth of age, women's ovarian function and intrauterine environment will change. Age will lead to a decline in the quality of follicles, and the quality of fertilized eggs may also have problems. In addition, the aging of women will be accompanied by the decline of fallopian tube function, and the fallopian tube patency will be reduced, which will easily lead to tubal pregnancy, that is, ectopic pregnancy. Most IVF babies are carried out by older women, so the probability of ectopic pregnancy will increase with age.
4. Personal disease factors
For women with certain diseases, the risk of ectopic pregnancy during IVF will also increase. For example, women with hysteromyoma, endometriosis, fallopian tube disease, etc. are more likely to have ectopic pregnancy. These diseases themselves will have adverse effects on the normal delivery of eggs and the implantation environment. In addition to the intervention of IVF surgery, the risk of ectopic pregnancy will further increase.
To sum up, although there is no direct causal relationship between the two, the excretion promoting drugs and surgical procedures used in IVF may increase the risk of ectopic pregnancy. In addition, age and personal disease are also important factors that affect the probability of ectopic pregnancy. Therefore, before IVF, we should choose a regular hospital, understand the relevant risks in detail, and make decisions under the guidance of doctors.
