Iatrogenic multiple pregnancy. Higher risk than a spontaneous one?

Area of Science:

• Obstetrics and Gynecology
• Reproductive Medicine
• Perinatal Medicine

Background:

• Multiple pregnancies are associated with increased maternal and fetal risks.
• Assisted reproductive techniques (ART) have led to a rise in induced multiple pregnancies.
• Understanding the comparative outcomes of spontaneous versus induced multiple gestations is essential for clinical management.

Purpose of the Study:

• To compare the antepartum, intrapartum, and fetal outcomes of spontaneous multiple pregnancies with those induced by fertility treatments.
• To identify specific risks associated with induced multiple gestations.

Main Methods:

• A retrospective study comparing spontaneous (Group A) and induced (Group B) multiple gestations.
• Data collected over a six-year period at a single institution.
• Analysis included surveillance, fetal outcomes, and incidence of specific complications.

Main Results:

• Induced multiple pregnancies had higher incidences of gestational diabetes and cervical insufficiency.
• While prematurity rates were similar, induced triplet pregnancies showed higher low birth weight and perinatal mortality.
• Fetal outcomes, assessed by Apgar score and umbilical cord blood pH, were significantly poorer in both induced groups.

Conclusions:

• Iatrogenic multiple pregnancies increase the likelihood of adverse events during pregnancy, labor, and postpartum.
• Assisted reproductive techniques necessitate thorough patient counseling due to increased pathological risks.
• Further research and improved management strategies are needed for iatrogenic multiple gestations.
