Summary
Assisted reproductive technologies effectively treat infertility but often result in multiple pregnancies. Improving current techniques like controlled ovarian hyperstimulation can help achieve more singleton births.
Area of Science:
- Reproductive medicine
- Infertility treatment
- Assisted reproductive technologies
Background:
- Assisted reproductive technologies (ART) have advanced significantly over the last two decades.
- ART now effectively addresses most causes of male and female infertility.
- Current ART methods are generally safe and cost-effective.
Purpose of the Study:
- To propose strategies for reducing multiple pregnancies in ART.
- To enhance existing ART techniques for improved singleton birth rates.
- To outline necessary improvements in ART procedures for future application.
Main Methods:
- Review and analysis of current ART techniques.
- Identification of areas for improvement in controlled ovarian hyperstimulation.
- Evaluation of fertilization, embryo culture, and cryopreservation procedures.
- Assessment of preimplantation genetic diagnosis applications.
Main Results:
- ART success rates have increased, but multiple pregnancies remain a significant adverse outcome.
- Existing techniques require refinement to minimize high-order multiple gestations.
- Improvements in controlled ovarian hyperstimulation, embryo culture, and genetic diagnosis are crucial.
Conclusions:
- Optimizing current ART techniques is essential for reducing multiple pregnancies.
- A focus on controlled ovarian hyperstimulation and embryo selection can promote singleton births.
- Future advancements in ART should prioritize singleton gestation to improve safety and outcomes.
