Development of in vitro maturation techniques for clinical applications

Area of Science:

• Reproductive Medicine
• Infertility Treatment
• Assisted Reproductive Technologies

Background:

• In vitro maturation (IVM) involves culturing immature oocytes for fertilization.
• IVM has demonstrated successful pregnancy and implantation rates, resulting in numerous healthy births.
• The source of immature oocytes is crucial for successful embryonic development and live births.

Purpose of the Study:

• To explore the potential of combining natural-cycle in vitro fertilization (IVF) with immature oocyte retrieval and IVM.
• To assess if simplifying immature oocyte retrieval can broaden access to IVM treatments for infertile women.
• To re-evaluate IVM technology and its development as a potential first-line infertility treatment.

Main Methods:

• Review of existing IVM protocols and outcomes.
• Analysis of combining mild-stimulation IVF with immature oocyte retrieval and subsequent IVM.
• Consideration of treatment process simplification for immature oocyte retrieval.

Main Results:

• IVM is an established treatment with acceptable pregnancy and implantation rates.
• Combining mild-stimulation IVF with IVM presents a viable alternative to standard treatments.
• Simplifying immature oocyte retrieval could expand IVM accessibility.

Conclusions:

• IVM technology has advanced significantly and warrants reconsideration.
• Mild-stimulation IVF combined with IVM may serve as an alternative or even a first-line infertility treatment.
• Further development and simplification of IVM procedures could enhance its role in assisted reproductive technologies.
