Complications of ovulation induction.
Induction of ovulation has its own risks. Since this treatment is elective the physician should be convinced that it is really indicated for the specific patient. Multiple pregnancies still occur in 4 to 15% in in vivo treatment and in 15 to 20% in assisted reproduction. Abortions occur in 20% of the pregnancies achieved. These numbers demonstrate the complexity of induction of ovulation. In recent years the average age of the treated patient has increased, but it is too early to see whether this influences the frequency of complications. The physician should be aware of the possible complications and should remain in contact with the patients at risk after completion of the treatment. The patient should be well informed about the possible complications before starting treatment. At the end of the treatment she should be able to recognize any clinical warning signs of OHSS and inform her physician, in order to be treated appropriately. Further studies of the pathogenesis of OHSS in the future will hopefully lead to more specific treatments or even prevention of this phenomenon. The increasing experience in selective fetal reduction seems to be a practical solution to high rank multifetal gestation, preventing extreme prematurity and its sequelae.
