Transvaginal sonographically controlled follicle puncture for oocyte retrieval

Area of Science:

• Reproductive Medicine
• Medical Imaging
• Gynecology

Background:

• In vitro fertilization (IVF) requires efficient oocyte retrieval.
• Traditional methods like laparoscopy involve risks and general anesthesia.
• Ultrasound-guided aspiration offers an alternative for oocyte retrieval.

Purpose of the Study:

• To evaluate the efficacy and safety of transvaginal sonographically guided follicle aspiration for oocyte retrieval in IVF.
• To compare this technique with other existing methods for oocyte retrieval.

Main Methods:

• Transvaginal ultrasound-guided follicle aspiration performed under local anesthesia.
• Oocyte retrieval using a sector scanner and needle introduced through the posterior fornix of the vagina.
• A transvaginal-transvesical variation was used for high ovaries.

Main Results:

• The procedure was performed on over 100 patients with favorable outcomes compared to other techniques.
• The method is minimally painful, easy to learn, and perform.
• Good oocyte number and quality were recovered, leading to five successful pregnancies and births.
• No significant adverse events were reported, with only minor venous punctures without sequelae.

Conclusions:

• Transvaginal sonographically guided follicle aspiration simplifies oocyte recovery for IVF.
• This technique allows for outpatient procedures, avoiding the risks and costs of laparoscopy and general anesthesia.
• It offers a comfortable and effective alternative to transabdominal-transvesical ultrasound-guided aspiration.
