“…The statistical significance between the outcomes of both groups was assessed using the student's t-test, Mann-Whitney test, and Pearson's Chi-square test. A p-value below 0.05 was deemed statistically significant [13][14][15].…”

“…The results of our investigation confirmed the findings of previous studies conducted by Ahmadi et al [ 10 ] and Smart et al [ 5 ]. The findings revealed a direct correlation between enhanced blood vessel formation in Zones 3 and 4 of the endometrium and higher rates of ovulation and pregnancy [ 14 , 16 ]. This highlights the need to evaluate the responsiveness of the uterus and predict treatment outcomes by taking into account levels of vascularity.…”

BackgroundInfertility remains a significant challenge affecting millions of couples worldwide, with ovulation abnormalities being a common underlying cause. Pharmacological methods, such as clomiphene citrate, are often used to stimulate ovulation. However, the optimal timing for sexual intercourse during ovulation induction remains contentious. ObjectivesThis study aimed to compare the efficacy of transvaginal ultrasonography (TVS) for measuring follicle size with Doppler ultrasound for assessing changes in blood flow to predict the timing of ovulation. MethodsWe conducted a comparative analysis involving 64 women undergoing infertility therapy. Participants were evaluated using both TVS to measure follicle diameter and Doppler ultrasound to assess perifollicular blood flow dynamics. The primary outcomes measured included ovulation rates, resistive index (RI) values, peak systolic velocity (PSV) values, and conception rates. ResultsThe analysis showed comparable age distributions between the TVS and Doppler groups. There was no significant correlation between follicle diameter and ovulation when assessed by TVS. However, Doppler ultrasound revealed a substantial association between perifollicular blood flow dynamics and ovulation. Higher ovulation rates were linked to lower RI values and higher PSV values, indicating their potential as predictors of ovulation. Additionally, higher conception rates were positively correlated with increased vascularity in Zone 4 of the endometrium. ConclusionDoppler ultrasonography indices, particularly RI and PSV values, provide critical insights into perifollicular blood flow dynamics and endometrial vascularity, which can enhance the effectiveness of fertility treatments. While these findings highlight the potential of Doppler ultrasound in predicting ovulation and improving treatment outcomes, further research is required to understand the underlying mechanisms and validate these results for personalised treatment strategies.

“…Changes in perfusion of the placenta and fetus can be reflected as increased vascular resistance of more proximal vessels. The uterine artery (UtA) is of particular interest as fetal activity does not affect its waveform, unlike those of the umbilical artery, umbilical vein, and middle cerebral artery [4][5][6][7].…”

“…Given the morbidity and mortality associated with placental disorders, uterine artery Doppler (UtA-Dop) screening has been playing a growing role in predicting FGR [4,5,6]. The most studied parameters are the pulsatility index (PI), resistance index (RI), and the presence of an early diastolic notch (DN) [4,5,6]. While PI and RI are quantitative measures, attempts to quantify the DN for the prediction of FGR are limited.…”

Purpose: We aimed to evaluate several quantitative methods to describe the diastolic notch (DN), and compare their performance in the prediction of fetal growth restriction. Materials and Methods: Patients who underwent a placental scan at 16-26 weeks’ gestation and delivered at between Jan 2016 and Dec 2020 were included. Uterine artery pulsatility index was measured for all of the patients. In patients with a DN, it was quantified using the notch index and notch depth index. Odds ratios for small for gestational age neonates (defined as birth weight <10th and <5th percentile) were calculated. Predictive values of uterine artery pulsatility, notch and notch depth index for fetal growth restriction were calculated. Results: Overall, 514 patients were included, of whom 69 (13.4%) delivered a small for gestational age neonate (birth weight<10th percentile). Of these, 20 (20.9%) had a mean uterine artery pulsatility index>95th percentile, 13 (18.8%) had a unilateral notch, and 11 (15.9%) had a bilateral notch. Sixteen patients (23.2%) had both a high uterine artery pulsatility index (>95th percentile) and a diastolic notch. Comparison of the performance between uterine artery pulsatility, notch and notch depth index using receiver operating characteristic curves to predict fetal growth restriction<10th percentile found area under the curve values of 0.659, 0.679 and 0.704, respectively, with overlapping confidence intervals. Conclusion: Quantifying the diastolic notch at 16-26 weeks of gestation did not provide any added benefit in terms of prediction of neonatal birth weight below the 10th or 5th percentile for gestational age, compared with uterine artery pulsatility index.
