This issue of Best Practice and Research, Clinical Obstetrics and Gynaecology is dedicated to the thousands of young women who, after transplantation of a solid vital organ, have attempted pregnancy, whose medical history is enshrined in the transplantation pregnancy register of their country. The registers’ data show that, because pregnancy after transplantation is associated with an increased risk of major complications, specific care must not stop at delivery, but it must become part of their reproductive health-care needs. Therefore, the main purpose of this volume is to provide professional information on all aspects of pre- and post-conceptional care, as well as on post-pregnancy reproductive health care relevant under such circumstances.

In the past decades, specific registers such as the National Transplantation Pregnancy Registry in the US, the United Kingdom Transplant Pregnancy Registry and the Australia and New Zealand Dialysis and Transplant Registry have been established to record the clinical outcomes of pregnancy in transplant recipients. These registers provide in many thousands of cases the history of all pregnancies in the respective countries, with detailed data on live births, spontaneous abortions, therapeutic abortion, stillbirths and ectopic pregnancies.

With the multidisciplinary assistance of international experts in different aspects of women’s health, we have attempted to provide the best possible information on pre- and post-conceptional, as well as reproductive health care for each of these women.

It is, however, clear that more research focused on pregnancy and reproductive health after solid organ grafting needs to be carried out and, hopefully, the listing of research areas at the end of each article will be helpful in stimulating research.
