What is the reason for molar pregnancy?

What causes a molar pregnancy? Molar pregnancies result when specific genetic errors occur during the fertilization of an egg by a sperm. In a healthy pregnancy, a placenta forms to nourish the growing embryo. With a molar pregnancy, instead of a placenta, a tumor forms inside the uterus.

Why does a molar pregnancy happen?

Molar pregnancies are caused by an imbalance in genetic material (chromosomes) in the pregnancy. This usually occurs when an egg that contains no genetic information is fertilised by a sperm (a complete molar pregnancy), or when a normal egg is fertilised by two sperm (a partial molar pregnancy).

Is molar pregnancy dangerous?

Most women who have a molar pregnancy can go on to have a healthy pregnancy later. The risk of having another molar pregnancy is only about 1 to 2 in 100 women (1 to 2 percent). If not treated, a molar pregnancy can be dangerous to the woman. It sometimes can cause a rare form of cancer.

Who is at risk for molar pregnancy?

The risk of complete molar pregnancy is highest in women over age 35 and younger than 20. The risk is even higher for women over age 45. Age is less likely to be a factor for partial moles. For choriocarcinoma, risk is lower before age 25, and then increases with age until menopause.

Is a molar pregnancy a real baby?

Complete molar pregnancies have only placental parts (there is no baby) and form when the sperm fertilizes an empty egg. Because the egg is empty, no baby is formed. The placenta grows and produces the pregnancy hormone, hCG. Unfortunately, an ultrasound will show that there is no fetus, only a placenta.

Can a molar pregnancy have a heartbeat?

Can a molar pregnancy turn into cancer?

Hydatidiform mole

This is called a molar pregnancy, but it is not possible for a normal baby to form. Still in rare cases (less than 1 in 100), a normal fetus can develop alongside the molar pregnancy. Hydatidiform moles are not cancerous, but they can develop into cancerous GTDs.

What happens after a molar pregnancy?

After a molar pregnancy has been removed, molar tissue may remain and continue to grow. This is called persistent gestational trophoblastic neoplasia (GTN). This occurs in approximately 15 to 20 percent of complete molar pregnancies, and up to 5 percent of partial molar pregnancies.

What does molar pregnancy look like on ultrasound?

The presence of the molar tissue is then detected. Ultrasound scanning shows a honeycomb pattern produced by the numerous vesicles.

How is molar pregnancy diagnosed?

A molar pregnancy can usually be diagnosed by abdominal ultrasound, which can show the presence of cysts in the uterus. A complete mole pregnancy may be easier to detect by ultrasound than a partial mole pregnancy. A woman will also be given a blood test to measure her levels of hCG.

What causes an empty egg?

Answer From Yvonne Butler Tobah, M.D. A blighted ovum, also called an anembryonic pregnancy, occurs when an early embryo never develops or stops developing, is resorbed and leaves an empty gestational sac. The reason this occurs is often unknown, but it may be due to chromosomal abnormalities in the fertilized egg.
