What are the causes of ectopic pregnancy?

When the fertilized egg fails to settle in the uterus due to various reasons, it often leads to ectopic pregnancy. So what are the reasons for ectopic pregnancy? The following describes the causes of ectopic pregnancy for you:

1. Obstructed ovulation: Pelvic inflammation causes periovarian inflammation and pelvic adhesions, which reduces the pressure in the follicles, and the granulosa cells and cumulus ovaries hinder the discharge of eggs. Pelvic inflammation is one of the causes of ectopic pregnancy.

2. The surface of the ovary is conducive to the implantation of the fertilized egg: the ovary can produce decidual tissue and there are endometriosis lesions on the surface of the ovary. These conditions are conducive to the implantation of the fertilized egg.

3. Damage to the function of the fallopian tube: Due to congenital or other reasons, the ciliary activity of the fallopian tube epithelium is abnormal or the fallopian tube produces reverse peristalsis, resulting in abnormal delivery of the fertilized egg.

4. Assisted reproductive technology: Some ectopic pregnancies that occur after assisted reproductive technology such as in vitro fertilization and embryo transfer are ovarian pregnancies.

5. Reproductive system: Primordial germ cells can cross-fertilize to form teratomas, primary choriomas, etc. before forming primordial follicles, but it seems difficult to use them to explain ovarian pregnancy.

6. Intrauterine contraceptive device: This is also the cause of ectopic pregnancy. Many literatures report that the use of intrauterine contraceptive device increases the risk of ovarian pregnancy. This may be related to changes in the intrauterine environment, increased prostaglandins and reverse peristalsis of the fallopian tube.

The above is an introduction to the causes of ectopic pregnancy. Experts remind female friends to pay more attention to the above reasons and do a good job of prevention. If you still have questions, you can consult online experts to answer them.
