Fetal reduction in a nontuplet pregnancy: technical and ethical considerations.

A case of a nontuplet pregnancy that was successfully reduced to twins resulting in a good neonatal outcome is described. A 37-year-old woman achieved a nontuplet pregnancy after ovarian stimulation with GnRH-analogues and gonadotrophins in the short protocol and artificial insemination. Reduction of the nontuplet pregnancy to twins was successfully performed in three attempts and delivery by caesarian section was followed on the 32nd week of pregnancy.
