Follicular flushing during oocyte retrieval is unnecessary. Aspiration alone yielded similar results in oocyte retrieval, fertilization, and pregnancy rates, while reducing operating time in infertility patients.
Area of Science:
- Reproductive Medicine
- In Vitro Fertilization
- Gynecology
Background:
- Transvaginal ultrasonically guided oocyte recovery is a key step in assisted reproductive technologies.
- The necessity of follicular flushing during this procedure remains debated.
Purpose of the Study:
- To evaluate the necessity of follicular flushing during transvaginal, ultrasonically guided oocyte recovery.
- To compare outcomes between aspiration only and aspiration with flushing groups.
Main Methods:
- Prospective randomized trial involving patients with tubal infertility.
- Two groups: Group 1 (aspiration only), Group 2 (aspiration and flushing).
- Oocyte retrieval performed under mild sedation.
Main Results:
- No significant difference in oocytes retrieved, fertilization rates, or pregnancy rates between the groups.
- Significantly shorter operating time in the aspiration only group.
Conclusions:
- Follicular flushing is not necessary during transvaginal oocyte recovery.
- Aspiration only technique is equally effective and more time-efficient.
