Abstract
Purpose
The aim of this study is to investigate the association of perifollicular blood flow (PFBF) with follicular fluid EG-VEGF, inhibin-a, and insulin-like growth factor-1 (IGF-1) concentrations, endometrial vascularity, and IVF outcomes.
Methods
Forty women with tubal factor infertility were included in a prospective cohort study. Each woman underwent IVF/ICSI procedure. Individual follicles of ≥16 mm (n = 156) were evaluated by power Doppler analysis and categorized as well-vascularized follicles (WVFs) or poorly vascularized follicles (PVFs). WVFs referred to those with perifollicular vascularity of 51–100 %. Each follicular fluid (FF) was individually aspirated and FF/serum EG-VEGF, inhibin-a, and FF IGF-1 levels were evaluated. Zones III–IV endometrial vascularity was classified as a well-vascularized endometrium (WVE). The presence of a WVE and mature oocytes, in addition to the embryo quality and clinical pregnancy rate (CPR), were recorded for each follicle. The main outcome measures were FF serum EG-VEGF, inhibin-a, IGF-1 levels, and WVE and IVF outcome per PFBF.
Results
For WVFs, the level of FF EG-VEGF (p = 0.008), oocyte quality (p = 0.001), embryo quality (p = 0.002), a WVE (p = 0.001), and CPR (p = 0.04) increased significantly. The pregnant group was characterized by increased numbers of WVFs (p = 0.044), a WVE (p = 0.022), and increased levels of FF IGF-1 (p = 0.001) and serum EG-VEGF (p = 0.03). FF IGF-1 >50 ng/mL (AUC 0.72) had 75 % sensitivity and 64 % specificity for predicting CPR.
Conclusions
WVFs yield high-quality oocytes and embryos, a WVE, increased FF EG-VEGF levels, and increased CPRs.
