PLOD1 and neoplasm: In females with gonadotroph NF-PitNETs, TGFBR3L staining was not associated with levels of circulating P-FSH (median 5.4 IU/L [IQR 3.8–13.6] and median 6.8 [IQR 3.9–9.9], in TGFBR3L negative and positive tumours respectively, p = 0.74) or P-LH (median 1.5 IU/L [IQR 0.7–7.8] and median 1.9 [IQR 1.3–4.8] in TGFBR3L negative and positive tumours respectively, p = 0.9).
