The National Transplantation Pregnancy Registry (NTPR) was established in 1991 at Thomas Jefferson University, Philadelphia, PA to study the outcomes of pregnancies in female transplant recipients and those fathered by male transplant recipients.

More than 1700 recipients, reporting over 2700 pregnancies, have participated in the registry. Included are kidney, liver, liver-kidney, pancreas-kidney, heart, heart-lung, and lung recipients from all over North America.

The NTPR is an ongoing study. Transplant coordinators, physicians and recipients are encouraged to submit a one-page recipient questionnaire regarding post-transplant pregnancies to the NTPR.

Support for the NTPR has been provided by grants from its founding sponsor, Novartis Pharmaceuticals Corporation, as well as Astellas Pharma US, Inc., Roche Laboratories Inc. and Wyeth Pharmaceuticals, Inc.
