One of the frustrating things, when dealing with Triploidy, was that there is not a lot of information available. The specialist offered us no resources and all of the information we got was found through a lot of online searching.
Here are a few that we found particularly helpful.
Unique - Triploidy
This was my favorite place for information regarding Triploidy. It is a six page pdf provided by an organization in the UK.
Triploidy Review - Texas DSHS
Put out by the Texas Department of State Health Services, an overview of several studies done of Triploidy pregnancies.
Triploidy Loss Support Group - BabyCenter
A support group on Baby Center for women specifically experiencing Triploidy pregnancy and loss.
For anyone looking for information on Triploidy, I hope these can help.
