Immunomorphological Features of the Placenta in Allogeneic Pregnancy as the Background for the Development of Obstetric Complications.

Objective: To study the structural and immunohistochemical features of placentas in women after assisted reproductive technology (ART) with allogeneic eggs (oocyte donation and surrogate motherhood).

Study Design: The study involved 89 women whose pregnancy occurred as a result of in vitro fertilization (IVF) with a donor egg in a surrogate motherhood program (IVF-SM, n = 47 patients) or oocyte donation (IVF-DO, n = 42). The comparison group consisted of 21 patients in whom pregnancy occurred as a result of IVF with their own egg (IVF-OE).

Structural, immunohistochemical and molecular features of placentas and placental sites after in vitro fertilization with donor eggs (surrogate motherhood).

Objective: to identify structural, immunohistochemical and molecular features of placentas and placental sites afterin vitro fertilization (IVF) with donor eggs (surrogate motherhood).

Study Design: morphological and immunohistochemical studies were performed on placental material obtained after delivery by caesarean section. The study included 26 women patients whose pregnancy resulted from IVF with a donor egg (IVF-SM group).
