The risk factors for polyembryoma are not well understood. However, some factors that may increase the risk of developing this condition include:

• Age: Polyembryoma is more common in women over the age of 40.

• Family history: Having a family history of polyembryoma may increase the risk of developing the condition.

• Fertility treatments: Women who have undergone fertility treatments may be at an increased risk of developing polyembryoma.

• Multiple pregnancies: Women who have had multiple pregnancies may be at an increased risk of developing polyembryoma.

• Obesity: Being overweight or obese may increase the risk of developing polyembryoma.

The treatment for polyembryoma depends on the size and location of the tumor. In some cases, the tumor can be surgically removed. Other treatments may include chemotherapy, radiation therapy, or hormone therapy. In some cases, a combination of treatments may be used.
