Molar Pregnancy


What’s a Molar Pregnancy?

molar pregnancy is an uncommon condition in which your uterus becomes “pregnant” with an abnormal growth instead of a viable embryo. Even though a molar pregnancy often feels like a normal pregnancy, the growth will not develop into a foetus. A molar pregnancy can happen when a sperm fertilises an abnormal egg that has no genetic information. This is known as a complete molar pregnancy. A partial molar pregnancy is when two sperm fertilise the same egg. The cells in a partial molar pregnancy may start to divide to create a malformed embryo and some placental tissue, but they won’t survive. Neither of these conditions has the correct amount of genetic information to become a viable embryo.


Complications with a Molar Pregnancy

The abnormal tissue must be removed right away. Although most of these growths are benign, they can sometimes become harmful tumours.If some molar tissue still remains even after removal, it may continue to grow and become cancerous. This complication occurs in about one out of five molar pregnancies.The fertilised egg triggers a pregnancy response in your body, which starts producing hormones to prepare for pregnancy. If in anscreenination we detect elevated levels of human chorionic gonadotropic (HCG) in your blood, it might indicate that you still have some molar tissue growing in your uterus.

This is known as persistent gestational trophoblastic disease (GTD) & may require treatment.


Signs and Symptoms of a Molar Pregnancy

A molar pregnancy will at first seem like a normal pregnancy. You may get morning sickness or miss your period. But usually you will see other symptoms as well, such as:

  • Vaginal bleeding
  • Pressure in the pelvis
  • Nausea and vomiting
  • Sweating
  • Fast or irregular heartbeat
  • Vaginal passing of tissue, especially grape-shaped cysts

If you’re experiencing these symptoms, call us right away. We will conduct a blood test and an ultrasound screen.


What will an Ultrasound of a Molar Pregnancy Show?

A molar pregnancy can usually be detected by 8 weeks. An ultrasound of a complete molar pregnancy will show:

  • No embryo or foetus
  • Cysts filling the uterus
  • Ovarian cysts
  • No amniotic fluid

A partial molar pregnancy will look much different. You will see:

  • A malformed foetus
  • Little amniotic fluid
  • A cystic placenta

We understand that this might be a very difficult situation to cope with emotionally. We want you to feel comfortable asking questions and expressing your concerns.
If you would like to try for pregnancy again, be aware that having a molar pregnancy increases the likelihood that you will have another. During your consultation at London Obs & Gynae Clinic please bring any questions you may have so we can discuss your future fertility options with you.
