Fraternal Twins Share Placenta?

Friday July 11, 2003
Doctors in the New England Journal of Medicine have documented a case of dizygotic (aka fraternal) twins sharing a placenta, contradicting common medical assumptions that only monozygotic (identical) share a single placenta in the womb. They acknowledge that the test-tube fertilization procedure used to conceive the twins could have been a factor influencing the placenta structure.

I had an ultrasound today. My twins appear to be sharing a placenta, but the membrain between them is thick. My doc is thinking that I’m having faternal twins, but dosen’t want to believe that they could share a placent. My twins were concived naturally.
