Abstract
Objective: To evaluate intraovarian resistance index (RI) in 47 healthy fertile volunteers with ovulatory cycles, 28 patients with luteal phase defect (LPD) and four patients with luteinized unruptured follicle (LUF Sy). Study design: Transvaginal color Doppler assessment of the follicular and corpus luteum blood flow and plasma progesterone (P) levels were obtained in each patient. Results: Significantly higher intraovarian artery RI (< 0.001) was obtained for LPD group than for controls during the luteal phase. In the control group both follicular and corpus luteum RI were significantly lower ( P < 0.001) on the dominant side, while in LPD group no difference ( P > 0.05) between the sides occurred. Mean P levels were significantly lower ( P < 0.001) in the LPD group (6.9 ± 2.3 ng/ml) than in controls (24.1 ± 11.4 ng/ml). In all the LPD patients histopathology revealed delayed endometrial pattern, while normal endometrial dating was found in all the evaluated patients from the control group ( n = 15). In the patients with LUF Sy ( n = 4) similar RI values were obtained in the follicular and corpus luteum phase. There was no difference between the sides in terms of the intraovarian RI. while subnormal values of P were obtained in all the examined patients (14.1 ± 6.2 ng/ml). Conclusion: Transvaginal color Doppler may predict the functional capacity of the corpus luteum.
