Noninvasive imaging systems for gametes and embryo selection in IVF programs: a review

Area of Science:

• Reproductive Medicine
• Biotechnology
• Medical Imaging

Background:

• Optimizing in vitro fertilization (IVF) involves enhancing pregnancy rates and reducing multiple births.
• The shift towards single embryo transfers necessitates improved, cost-effective, and noninvasive embryo selection methods.
• High-tech gamete and embryo testing/selection procedures are crucial for advancing assisted reproductive technology (ART).

Purpose of the Study:

• To evaluate the efficacy of noninvasive imaging systems for embryo selection in ART.
• To explore the clinical applications of these imaging systems for infertile patients undergoing ART.
• To review advanced imaging techniques for gamete and preimplantation embryo selection.

Main Methods:

• Review of current literature on noninvasive imaging systems for embryo selection.
• Focus on three advanced imaging systems: motile sperm organelle morphology examination, polarization microscopy, and time-lapse monitoring.
• Assessment of their potential clinical application in assisted reproductive technology.

Main Results:

• Noninvasive imaging systems show promise for enhancing embryo selection in IVF.
• Motile sperm organelle morphology examination, polarization microscopy, and time-lapse monitoring are key technologies.
• These methods can aid in selecting optimal gametes and preimplantation embryos for transfer.

Conclusions:

• Noninvasive imaging systems are vital for improving the efficiency of assisted reproductive technology.
• These technologies support the goal of increasing pregnancy rates and reducing multiple pregnancies in IVF.
• Further clinical application of these advanced imaging techniques is recommended for infertile patients.
