VEGFB and polycystic ovary syndrome: In a group of 103 women with polycystic ovary syndrome and 96 age-matched healthy controls, Cheng et al. [61] found that both lean and overweight/obese patients with polycystic ovary syndrome had higher plasma VEGF-B levels than the healthy controls (P<0.05) and that VEGF-B levels were correlated with BMI, body fat percentage, homoeostasis model assessment of IR and β-cell function indices.
