Transvaginal sonographically guided oocyte retrieval for in-vitro fertilization

Area of Science:

• Reproductive Medicine
• Minimally Invasive Surgery
• Assisted Reproductive Technologies

Background:

• Oocyte retrieval is a critical step in in-vitro fertilization (IVF).
• Traditional methods like laparoscopy have limitations, including the need for general anesthesia and potential complications.
• Sonographically guided techniques offer a less invasive alternative.

Purpose of the Study:

• To evaluate the safety and efficacy of transvaginal sonographically guided oocyte retrieval.
• To compare the outcomes of transvaginal oocyte retrieval with other established methods.
• To determine pregnancy rates associated with this technique.

Main Methods:

• 588 transvaginal sonographically guided oocyte retrievals were performed using a vaginal transducer.
• The procedure was conducted for in-vitro fertilization cycles.
• Data on accessibility of follicles, complications, and pregnancy rates were collected.

Main Results:

• All follicles were accessible in the procedures performed.
• A very low complication rate was observed (one case of pelviperitonitis).
• Clinical pregnancies were achieved in 85 patients, with pregnancy rates of 19.0% per embryo transfer, 14.5% per oocyte retrieval, and 12.0% per stimulated cycle.

Conclusions:

• Transvaginal sonographically guided oocyte retrieval is a safe, non-invasive, and effective method for IVF.
• It offers significant advantages over laparoscopic retrieval, including no need for general anesthesia and fewer complications.
• This technique is recommended as the method of choice for oocyte retrieval in most IVF cases.
