Corneal pregnancy means that the embryo implants in the uterine horns instead of in the normal uterine cavity. This situation is rare, but it is a serious pregnancy complication that can easily lead to uterine rupture and massive bleeding, seriously threatening the life safety of pregnant women. So, what causes uterine pregnancy? Let’s learn more about it below. How to deal with uterine horn pregnancy. Congenital factors. Corneal pregnancy is related to uterine morphological malformations, such as uterine bicornuate malformation, uterine horn malformation, endometriosis, etc. Due to the small size of the uterine horn, the embryo cannot receive adequate nutrition and support after implantation, which can easily lead to embryonic stagnation and pregnancy abnormalities. Acquired factors (1) Uterine horn surgery: such as uterine horn resection, uterine gonioplasty, uterine myomectomy, etc. These surgeries may damage the tissue and structure of the uterine horn, causing the embryo to implant here. (2) Artificial insemination: Artificial insemination is an assisted reproductive technology that injects sperm directly into the uterine horn, which can easily cause the embryo to implant here. (3) Hormone therapy: Long-term use of hormonal drugs such as estrogen and progesterone may cause endometrial hyperplasia and hypertrophy in the uterine horns, affecting the implantation of the embryo in the uterine cavity. (4) Cervical laxity: Cervical laxity means that the cervix is loose and the opening is too large, which can easily cause the embryo to implant in the cervix, and then develop into a uterine horn pregnancy. Other factors (1) Age factor: As age increases, the tissue and structure of the uterus and uterine horns will change, thus affecting the implantation and development of the embryo. (2) Genetic factors: Some genetic diseases, such as Turner syndrome, Mayer-Rokitansky-Kuster-Hauser syndrome, etc., may be related to uterine horn pregnancy. In general, the causes of uterine corneal pregnancy are complex, involving both congenital and acquired factors, and may also be related to other factors. Therefore, it is necessary to conduct a comprehensive gynecological examination before giving birth to detect and treat uterine morphological deformities and other problems in a timely manner to reduce the occurrence of uterine horn pregnancy. If a uterine corneal pregnancy has occurred, you need to seek medical treatment promptly and choose an appropriate treatment plan according to the specific situation to ensure the life safety of the pregnant woman.
