Risk factors
Approximately 1 in every 1,000 pregnancies is diagnosed as a molar pregnancy. Various factors are associated with molar pregnancy, including:
- Maternal age. A molar pregnancy is more likely in women older than age 35 or younger than age 20.
- Previous molar pregnancy. If you've had one molar pregnancy, you're more likely to have another. A repeat molar pregnancy happens, on average, in 1 out of every 100 women.
