Abstract
To evaluate the mid - luteal phase resistant index (RI) and pulsatlity index (PI) of uterine and ovarian arteries with evaluation of endometrial and sub endometrial blood flow in unexplained infertility patients and compare those parameters with fertile controls in order to reveal the possible role of the uterine perfusion in the infertility etiopathogenesis. In this study, randomized study include 100 participants presented to the outpatient clinic in Kasr Elaini maternity hospital, they were classified into two groups (group A): 50 participants presented with unexplained infertility either primary or secondary (the case group). (group B): 50 participants who had no history of infertility and multipara who came for any gynecological procedure (the control group) Primary outcome measures resistant index (RI) and pulsitility index (PI) of both uterine and ovarian arteries with detection of (VI) (FI) and (VFI) of endometrial and subendmetrial areas using (VOCAL) in mid luteal phase after measurement of serum progesterone level in both groups. The uterine artery (RI) is higher in case group (0.86 ± 0.06) (0.85 ± 0.07) than in control group (0.77 ± 0.04), The ovarian artery (RI) is higher in case group (0.66 ± 0.03) (0.65 ± 0.08) than in control group (0.63±0.02). The uterine artery (PI) is higher in case group (2.17 ± 0.22) (2.14 ± 0.16) than in control group (1.80 ± 0.10) (1.80 ± 0.15) and the ovarian artery (PI) is higher in case group 1.97 ± 0.13 - 1.97 ± 0.12 than in control group 1.54 ± 0.17 - 1.56 ± 0.17 which all statistically significant
