Single or Double-Lumen Aspiration Needle? Revisiting Choices for In Vitro Fertilization or Intracytoplasmic Sperm...

Area of Science:

• Reproductive Medicine
• Ultrasound-Guided Procedures
• Assisted Reproductive Technology (ART)

Background:

• Transvaginal ultrasound-guided follicle aspiration is the standard for oocyte retrieval in ART.
• Both single-lumen aspiration needles (SLN) and double-lumen aspiration needles (DLN) are utilized for this procedure.

Purpose of the Study:

• To systematically compare the clinical outcomes and impact of using SLN versus DLN in women undergoing ART.
• To evaluate differences in oocyte yield, procedural efficiency, and safety between SLN and DLN.

Main Methods:

• A systematic literature search was performed on PubMed and Google Scholar until May 2025.
• Five studies were included, comparing SLN and DLN in ART procedures.
• Outcomes analyzed included oocyte yield, MII oocytes, procedural duration, complications, fertilization rates, embryo quality, and pregnancy rates.

Main Results:

• No significant differences were found in oocyte yield or MII oocyte count between SLN and DLN.
• Procedures using SLN were significantly shorter than those using DLN.
• Fertilization rates, embryo quality, and clinical pregnancy, ongoing pregnancy, and live birth rates were comparable between the two needle types.

Conclusions:

• Single-lumen needles (SLN) demonstrate comparable efficacy to double-lumen needles (DLN) for oocyte retrieval in ART.
• SLN offers a potential advantage in reducing procedural duration without negatively impacting key ART outcomes.
• The choice between SLN and DLN may be based on procedural efficiency and patient factors.
