- Background
This study aimed to evaluate ovarian reserve in patients with unilateral endometrioma by exploring correlations between serum anti-Müllerian hormone (AMH) levels and imaging markers derived from ultrasonography and magnetic resonance imaging (MRI).
Methods
We conducted a retrospective study of 146 female patients diagnosed with unilateral endometrioma at a single tertiary hospital between 2015 and 2023. Ovarian size was measured using ultrasonography and MRI, and various absolute and relative indicators were calculated. Serum AMH levels and inflammatory markers were assessed, and statistical analyses were performed to examine correlations between AMH levels and imaging markers.
Results
The participants’ mean age and AMH level were 32.01±5.99 years and 3.54±3.24 ng/mL, respectively. Serum AMH levels were significantly negatively correlated with age and body mass index. Among ultrasonographic parameters, only the maximum diameter of the healthy ovary showed a significant positive correlation with AMH levels. Among MRI-derived parameters, the maximum diameter, mean diameter, and volume of the healthy ovary exhibited significant positive correlations with AMH, whereas the relative volume of the affected ovary showed no significant correlation with AMH. These findings suggest that the healthy ovary plays a crucial role in maintaining ovarian reserve.
Conclusions
In women with unilateral endometrioma, the size and volume of the healthy ovary are significantly associated with serum AMH levels. This information is useful for accurately assessing ovarian reserve. These findings highlight the importance of considering the healthy ovary in treatment planning and counseling for women with unilateral endometrioma.
