A case of conjoined twins after a transfer of a multinuclear embryo
نویسندگان
چکیده
A pregnancy with conjoined twins was observed after transfer of a multinuclear embryo. As nuclear mechanisms have a role in cellular differentiation, association between multinucleation and fetal malformations is possible. Follow-up studies on children born after transfer of embryos with bi/multinuclear blastomeres are needed.

The most common type is thoracopagus. Prenatal diagnosis is based on sonography and, more accurately, on magnetic resonance imaging. In this paper, two cases of ...
