Table 1 Comparison between the unexplained infertility group and the fertile control group according to the mean values of age, uterine arteries resistance index, pulsatility index, systolic/diastolic ratios, and endometrial thickness
From: Role of uterine artery Doppler in assessment of unexplained infertility
|  | Unexplained infertility group(n = 40) Mean ± SD | Fertile control group (n = 30) Mean ± SD | p value |
|---|---|---|---|
Age (years) | 26.9 ± 3.8 | 28.5 ± 4.9 | 0.194# |
Resistance index | 0.9 ± 0.06 | 0.6 ± 0.04 | < 0.0001*¶ |
Pulsatility index | 2.9 ± 0.7 | 1.5 ±0.4 | < 0.0001*# |
systolic/diastolic ratio (S/D): | 8.0 ± 3.4 | 2.7 ± 0.3 | < 0.0001*¶ |
Endometrial thickness | 10.4 ± 2.4 | 12.1 ± 1.8 | < 0.001*¶ |
