Early pregnancy wastage in IVF (in vitro fertilization) patients
1Cornell University Medical College, Department of Obstetrics and Gynecology, New York, New York 10021.
Abstract:
Human in vitro fertilization is characterized by a low efficiency of implantation. Possible mechanisms for pregnancy loss are discussed. Embryo viability or quality, abnormal implantation, and delayed or absent corpus luteum rescue may all play a role in pregnancy wastage. Defining the possible mechanism for these losses may allow hormonal treatment to correct specific abnormalities.
