Silvia Azaña, an embryologist at inviTRA, tells us in this video about the main risk factors for extrauterine or ectopic pregnancy:
An ectopic pregnancy, also known as extrauterine pregnancy, refers to a complication that arises when the embryo implants in a location outside the uterus. The most common location for an ectopic pregnancy is the fallopian tube, occurring in 95% of cases. Nonetheless, there is a possibility that an ectopic pregnancy may be found in other areas, including the abdominal cavity, the cervix or the ovary.
There are several risk factors that have been identified which could raise the chances of experiencing an ectopic pregnancy, including the following:
Tubal factor. Salpingitis. Congenital defects in the fallopian tubes.
Pelvic surgery or abdominal surgery.
Pelvic inflammatory disease.
Endometriosis and also a maternal age over 35 years old.
Tobacco use.
A pregnancy with an intrauterine device.
A previous ectopic pregnancy.
And assisted reproduction techniques.
