Immune cells are essential for endometrial receptivity to embryo implantation and early
placental development. They exert tissue-remodeling and immune regulatory roles—acting …

Objective To determine whether there are differences in adverse pregnancy outcomes in
very advanced maternal age (vAMA) women who conceived with assisted reproductive …

The fetus is a semi-allograft for the maternal host in natural pregnancy, but the fetus is a
complete allograft after oocyte donation (OD), and there is greater antigenic dissimilarity with …

In oocyte donation (OD) pregnancies, a fetus is a complete allograft to the maternal host and
OD pregnancies are an independent risk factor for preeclampsia. Immunocompetent cells …

Introduction Oocyte donation (OD) pregnancy is a risk factor for pre-eclampsia (PE). Due to a
higher extent of fetal-maternal human leukocyte antigens (HLA) mismatching in OD …

Purpose Assess the risk of ischemic placental disease (IPD) among in vitro fertilization (IVF;
donor and autologous) pregnancies compared with non-IVF pregnancies. Methods This was …

In oocyte donation (OD) pregnancy, a fetus can be completely allogeneic to the recipient.
Consequently, the maternal immune system has to cope with greater immunogenetic …

Pregnancy is a fascinating immunological paradox: the semi-allogeneic fetus generally
grows without any complications. In the placenta, fetal trophoblast cells come into contact …

Background Fetuses in pregnancies conceived after oocyte donation (OD) have a higher
degree of antigeneic dissimilarity with the mother compared to semi-allogeneic fetuses after …

Oocyte donation (OD) pregnancies are characterized by a complete immunogenetic
dissimilarity between mother and fetus, which requires enhanced immunoregulation …
