Summary
Bidimensional echography provides normal reference values for ovarian and follicular volumes during the ovulatory cycle. This imaging technique is valuable for diagnosing ovarian functional disorders.
Area of Science:
- Reproductive Endocrinology
- Medical Imaging
- Gynecology
Background:
- Understanding normal ovarian dynamics is crucial for diagnosing reproductive disorders.
- Bidimensional echography is a non-invasive imaging modality for assessing reproductive organs.
Purpose of the Study:
- To establish normal reference values for ovarian and follicular volumes throughout the ovulatory cycle using bidimensional echography.
- To evaluate changes in ovarian volume, dominant follicle volume, corpus luteum volume, residual follicular volume, and stromal volume during normal ovulatory cycles.
Main Methods:
- 25 normal ovulatory cycles were evaluated using bidimensional echography.
- Key parameters measured included ovarian, dominant follicle, corpus luteum, residual follicular, and stromal volumes.
- Measurements were taken at various points throughout the ovulatory cycle.
Main Results:
- Ovarian and dominant follicle volumes peaked on day -1 (11.68 ± 2.87 ml and 3.60 ± 1.20 ml, respectively).
- Maximum stromal volume occurred during the follicular phase (7.98 ± 2.29 ml) and post-ovulation in the dominant ovary (8.64 ± 2.53 ml on day +7).
- Residual follicular volume decreased gradually, with minor post-ovulatory fluctuations.
Conclusions:
- This study provides normative data for ovarian and follicular volumes during the ovulatory cycle.
- Bidimensional echography is a useful tool for diagnosing functional ovarian disorders by comparing patient data to these established normal values.
