What is a molar pregnancy? What is a chemical pregnancy?

Answer 1

A molar pregnancy happens when there are certain abnormalities in the fertilized egg at conception. The fertilized egg either never develops into an embryo (this is called a complete mole) or it develops abnormally and can't survive (this is a partial mole).

In normal pregnancies, the fertilized egg contains 23 chromosomes from the father and 23 from the mother. In most complete molar pregnancies, the fertilized egg contributes no maternal chromosomes and the chromosomes from the father's sperm are duplicated, so you end up with two copies of chromosomes from the father and none from the mother. In this case, there's no embryo, amniotic sac, or any normal placental tissue. Instead, the placenta forms a mass of cysts that looks like a cluster of grapes.

In most partial molar pregnancies, the fertilized egg has the normal complement of chromosomes from the mother but double the chromosomes from the father, so there are 69 chromosomes instead of the normal 46. (That can happen when chromosomes from the sperm are duplicated or when two sperm fertilize the same egg.) In this case, there's some normal placental tissue among the cluster-like mass of abnormal tissue. The embryo does begin to develop, so there may be a fetus, or just some fetal tissue, or an amniotic sac. But even if a fetus is present, in most cases it's so abnormal that it can't survive.

It can be scary and sad to lose a pregnancy this way. But as long as you get proper treatment, you're unlikely to have any long-term physical consequences.

How common are molar pregnancies?
About one in every 1,000 pregnancies in the United States is a molar pregnancy. If you're under age 20 or over age 40 or if you've had a previous molar pregnancy or two or more miscarriages, your chances of having a molar pregnancy are higher.

What is a chemical pregnancy - A pregnancy is called a chemical pregnancy if you test positive for pregnancy but start you period a few days later.

How common are they? - Unfortunately, too common. The numbers vary depending on the source, but generally up to 50 to 60 percent of all first pregnancies end in miscarriage--usually too early for the mother to know. With HPT's becoming more sensitive, we know about more of these early miscarriages than before.

I hope this is helpful to you.

Answer 2

A chemical pregnancy is the term given to a pregnancy that ends very early in the first trimester. Chemical pregnancies are confirmed by testing for hCG, the hormones that indicate the presence of a pregnancy. These hormones are typically detected by a urine or blood pregnancy test. However, within weeks, these hCG levels begin to drop rapidly, signifying an end to the pregnancy. As a result, your baby and his amniotic sac cannot be seen on an ultrasound and a miscarriage takes place.

It is believed that chemical pregnancies occur when the fetus dies immediately after conception. This happens before the embryo has a chance to implant in your uterus where it can grow and develop. Like a stillbirth or molar pregnancy, chemical

Answer 3

Molar: This occurs when the nucleus of an egg is either lost or inactivated. The sperm then duplicates itself because the egg was lacking genetic information. Usually there is no fetus, no placenta, no fluid and no amniotic membranes.

The uterus is rather filled with the mole that resembles a bunch of grapes.

A chemical pregnancy is the clinical term used for a very early miscarriage. In many cases, the positive pregnancy test was achieved before the woman's period was due but a miscarrige occured before a heartbeat was able to be seen on an ultrasound.

Answer 4

Not that kind of molar doctorhector.

Answer 5

there have been dental formations on the ovaries, nobody knows why... the chemical one never heard of it

Answer 6

Naw - I can't say what just came to mind.
