IVF and related technology. The present and the future

Area of Science:

• Reproductive Medicine
• Genetics
• Infertility Treatment

Background:

• In-vitro fertilisation (IVF) and related assisted reproductive technologies (ART) have evolved significantly.
• Understanding the indications, challenges, and advancements in ART is crucial for managing infertility.
• Key areas include stimulated cycles, embryo and gamete cryopreservation, and novel micromanipulation techniques.

Purpose of the Study:

• To review the current status and applications of IVF and associated technologies.
• To discuss indications, challenges of stimulated cycles, and alternatives like immature egg collection.
• To highlight advancements in gamete micromanipulation and preimplantation genetic diagnosis.

Main Methods:

• Review of clinical experience and research from Monash IVF and Monash University.
• Inclusion of key original and review articles from global scientific literature.
• Analysis of cumulative pregnancy rates and outcomes of various ART procedures.

Main Results:

• Gamete intrafallopian transfer (GIFT) shows higher success rates (55%) than IVF (29%) in Australia.
• Gonadotrophin-releasing hormone (GnRH) analogues improve pregnancy rates and reduce monitoring.
• Risks of stimulated cycles (multiple pregnancies, hyperstimulation) are being mitigated; embryo freezing and donor eggs contribute to success.
• Micromanipulation techniques address severe male infertility, and preimplantation genetic diagnosis aids in selecting healthy embryos.

Conclusions:

• ART is a valuable option for couples with intractable infertility, offering birth rates comparable to natural conception.
• Congenital malformation rates are not increased with ART.
• Treatment complexity, cost, and patient stress are decreasing, with ongoing improvements in safety and efficacy.
