Introduction
In general, ovarian pregnancy refers to the implantation and development of a fertilized egg within the ovary, and it is a rare form of ectopic pregnancy. Normally, the fertilized egg implants within the uterine cavity. Ovarian pregnancy occurs primarily when an egg is fertilized on the surface of the ovary after ovulation, or when the fertilized egg flows backward from the fallopian tube into the ovary and begins to develop under favorable local conditions for implantation.
Generally, ovarian pregnancy refers to the implantation and development of a fertilized egg within the ovary. It is a rare form of ectopic pregnancy. A detailed explanation is as follows:
Under normal circumstances, the fertilized egg implants inside the uterine cavity. Ovarian pregnancy mainly occurs when an egg is fertilized on the surface of the ovary after ovulation, or when the fertilized egg flows backward from the fallopian tube into the ovary and begins to develop under favorable local conditions for implantation. In cases of ovarian pregnancy, as the embryo grows, it damages the ovarian tissue. Given the rich blood supply of the ovary, once the gestational sac ruptures, it can easily cause severe internal hemorrhage in the abdominal cavity, which is a very dangerous situation that can threaten life. Clinical manifestations may include amenorrhea (absence of menstruation), abdominal pain, and slight vaginal bleeding.
It is important to use contraception methods scientifically and appropriately in daily life. For example, correctly taking short-acting contraceptive pills and properly using condoms can effectively reduce the occurrence of unintended pregnancies, including the risk of ectopic pregnancy.
