Transrectal vs. transvaginal oocyte retrieval in patients requesting egg freezing for fertility preservation: a prospective observational study
Comparative Analysis of Transrectal and Transvaginal Oocyte Retrieval Techniques
Overview
This study evaluates transrectal oocyte retrieval (TROR) as an alternative to transvaginal oocyte retrieval (TVOR) for patients with intact hymens. Results indicate that while TVOR remains the standard method, TROR may be considered for specific patient populations.
Background
Oocyte cryopreservation is a critical assisted reproductive technology that allows women to preserve their fertility for various medical and non-medical reasons. Traditional transvaginal ultrasound-guided retrieval is not suitable for all patients, particularly those with intact hymens. This study aims to provide insights into the efficacy of TROR in comparison to the conventional method.

Key Findings
Number of oocytes retrieved negatively correlates with age in both TROR and TVOR groups.
AMH levels show a strong positive correlation with the number of oocytes retrieved in TROR.
Both retrieval methods demonstrate significant correlations with anesthesia time, surgery time, and peak E2 levels.
TROR and TVOR have different correlation strengths with BMI.
Clinical Implications
Understanding the correlations between various factors and oocyte yield can aid in optimizing retrieval strategies.
Conclusion
While transvaginal oocyte retrieval remains the standard, transrectal oocyte retrieval offers an alternative for specific patient populations.
