In the past twenty years, the increased number of organ transplant recipients and better immunosuppressive regims have enhanced transplant survival, and several transplant recipients may conceive pregnancy or paternity after the graft. There is no French registry of posttransplant pregnancies, but analysis of the international literature reports 2300 pregnancies after kidney transplantation, 100 pregnancies after heart and 3 after heart-lung transplantation, 90 pregnancies after liver transplantation. Paternity after the graft may occur with no increased incidence of malformations, nor teratogenic and immunosuppressive effects due to the therapeutic regimen. All pregnancies after transplantation have to be considered at high risk, underlying the need for simultaneous follow-up by the gyneco-obstetrical team for the baby and the pregnancy and by the transplant team for the graft and the mother. Outcome is generally excellent for the mother and the baby. However, transplant recipients with either high blood pressure, diabetes, serum creatinine above 160 mumol/l or within less than 1 year after the graft should be considered at too high risk to conceive a pregnancy with no deleterious effect on the mother and/or on the foetus.
