An ectopic pregnancy is an abnormal pregnancy, most of which are benign. However, if not diagnosed and treated early, it can lead to dangerous complications.

1. What is egg pregnancy?

An ovum, also known as an ovum, is a rare complication of pregnancy that is characterized by the abnormal growth of trophoblasts, the cells that normally develop into the placenta.
Ovulation may seem like a normal pregnancy at first, but most ovulatory pregnancies cause specific signs and symptoms, including:
Vaginal bleeding that is dark brown to red fresh in the first trimester Nausea and vomiting a lot Rapidly enlarged abdomen, uterus too large for normal pregnancy Pelvic pressure or pain.

2. Causes of pregnancy

The cause of this phenomenon is that part or all of the chorion (the chorion surrounding the embryo) has degenerated into fluid sacs of many sizes. They clump together and invade the uterine cavity. There are two types of ovum, full ovum and partial ovum.
When the pregnant woman's uterus contains only fluid sacs, there is no formation of fetal tissue, it is called a total ovum. With a partial ovum, there may be normal placental tissue along with a sac of fluid. Fetal formation is also possible, but the fetus cannot survive and is often miscarried early in the pregnancy.
Pregnancy is caused by an abnormally fertilized egg. Human cells normally contain 23 pairs of chromosomes. One chromosome in each pair comes from the father, the other from the mother.
In complete ovum: An egg is fertilized by one or two sperm, and all the genetic material comes from the father. In this situation, chromosomes from the mother's egg are lost or inactivated and the father's chromosomes are duplicated. It is the defect in the genetic system that it cannot develop into a normal fetus, but instead develops a fetus without an embryo. In a partial pregnancy: The mother's chromosomes are still there, but the father provides two sets of chromosomes. As a result, the embryo has 69 chromosomes instead of 46. This usually happens when two sperm fertilize an egg, resulting in an extra copy of the father's genetic material.

3. Complications of pregnancy

Once the egg is removed, the abnormal egg tissue may remain and continue to grow. Also known as Gestational Trophoblastic Neoplasia (GTN). Approximately more than 80% of cases of ectopic pregnancy will return to normal, up to 15 to 20% of complete oocytes have complications with glioblastoma, and about 5% of partial oocytes. One sign of trophoblastic hyperplasia is an increased level of HCG (a pregnancy hormone). In some cases, the ovum invades deep into the middle layer of the uterine wall, causing vaginal bleeding. GTN can be successfully treated, most often with chemotherapy. Another treatment option is a hysterectomy. Rarely, a form of trophoblastic hyperplasia causes carcinoma, which grows and spreads to other organs. Carcinoma can be completely cured with many cancer drugs. A complete ovum is more likely to have this complication than a partial ovum.
