Area of Science:

  • Reproductive Medicine
  • Embryology
  • In Vitro Fertilization (IVF)

Background:

  • Embryo transfer is a critical step in assisted reproductive technologies.
  • Various methods exist, each with unique success factors and potential complications.
  • Optimizing embryo transfer is key to improving pregnancy rates and minimizing risks.

Purpose of the Study:

  • To review and detail various embryo transfer methods.
  • To identify critical factors influencing the success of embryo transfer.
  • To discuss strategies for improving outcomes and reducing multiple pregnancies.

Main Methods:

  • Review of transcervical intrauterine transfer, including influencing variables.
  • Discussion of embryo quality, developmental stage, and transfer number.
  • Examination of ultrasound-guided and surgical embryo transfer techniques.

Main Results:

  • Transcervical intrauterine transfer is common, but success depends on technical skill, catheter choice, and minimizing uterine trauma.
  • Embryo quality, blastocyst culture, and single embryo transfer can reduce multiple pregnancies.
  • Advanced techniques like ultrasound-guided transfer and cryopreservation offer improved options.

Conclusions:

  • Careful attention to technique and embryo selection is vital for effective embryo transfer.
  • Minimizing trauma and optimizing embryo quality are key to successful implantation and reduced multiple births.
  • Modern laboratory advancements have refined assisted reproductive technologies, making older surgical methods less common.
