Summary
Assisted reproductive technology (ART) may increase iatrogenesis. Frozen embryo transfer and GnRH agonist trigger in segmented ART offer improved outcomes for mothers and infants compared to fresh embryo transfer.
Area of Science:
- Reproductive Medicine
- Obstetrics and Gynecology
- Perinatology
Background:
- Assisted reproductive technology (ART) accounts for up to 4% of infant conceptions in developing nations.
- ART procedures, while often successful, carry risks of iatrogenesis (medically induced harm).
- Controlled ovarian stimulation (COS) can alter the endocrine profile, potentially impacting implantation and fetal development.
Purpose of the Study:
- To review the clinical and scientific evidence of iatrogenesis in ART.
- To evaluate the evolution of ART technologies and their impact on maternal and fetal outcomes.
- To assess the benefits of frozen embryo transfer (FET) over fresh embryo transfer (ET).
Main Methods:
- Review of existing clinical and scientific literature on iatrogenesis in ART.
- Analysis of the effects of controlled ovarian stimulation on reproductive cycles and outcomes.
- Evaluation of evidence supporting frozen embryo transfer versus fresh embryo transfer.
Main Results:
- COS can lead to ovarian hyperstimulation syndrome, reduced implantation, ectopic pregnancy, and altered placentation/fetal growth.
- Frozen embryo transfer (FET) is increasingly presumed to be more optimal than fresh embryo transfer for reproductive, maternal, and fetal outcomes.
- GnRH agonist (GnRHa) trigger in segmented ART shows promise for improved patient outcomes.
Conclusions:
- Segmented ART with GnRHa trigger may become a future standard for IVF patients.
- FET appears superior to fresh ET regarding maternal and fetal health.
- ART advancements aim to minimize iatrogenesis and enhance safety and efficacy.
