Sex Hormone-Binding Globulin (SHBG) as an Early Biomarker and Therapeutic Target in Polycystic Ovary Syndrome

Open access

Abstract

Human sex hormone-binding globulin (SHBG) is a glycoprotein produced by the liver that binds sex steroids with high affinity and specificity. Clinical observations and reports in the literature have suggested a negative correlation between circulating SHBG levels and markers of non-alcoholic fatty liver disease (NAFLD) and insulin resistance. Decreased SHBG levels increase the bioavailability of androgens, which in turn leads to progression of ovarian pathology, anovulation and the phenotypic characteristics of polycystic ovarian syndrome (PCOS). This review will use a case report to illustrate the inter-relationships between SHBG, NAFLD and PCOS. In particular, we will review the evidence that low hepatic SHBG production may be a key step in the pathogenesis of PCOS. Furthermore, there is emerging evidence that serum SHBG levels may be useful as a diagnostic biomarker and therapeutic target for managing women with PCOS.

  • Lower levels of sex hormone-binding globulin (SHBG) indicate anomalous cholesterol measurements connected to inhibited insulin signaling, such as in PCOS.

    “Lower levels of the blood protein called sex hormone-binding globulin (SHBG) are advised to indicate the anomalous cholesterol measurements which are connected to inhibited insulin signaling, for instance, PCOS [112].”

    From Nutritional and herbal interventions for polycystic ovary syndrome (PCOS): a comprehensive review of dietary approaches, macronutrient impact, and herbal medicine in management (2025) · cites this paper as [112]

    Section 3.3 describes low SHBG as a biomarker of insulin resistance, and Section 4.3 discusses lower SHBG in women with PCOS. Section 4.3 also reports that treatment increased SHBG while reducing LDL cholesterol, but it does not establish that low SHBG indicates abnormal cholesterol measurements.

    Experimental — accuracy not yet measured
  • Together with free T, SHBG has recently been recognized as a useful diagnostic marker and therapeutic target for managing women with PCOS.

    “Together with free T, SHBG has recently been recognized a useful diagnostic marker and therapeutic target for managing women with PCOS [195].”

    From Role of sex hormone-binding globulin in the free hormone hypothesis and the relevance of free testosterone in androgen physiology (2022) · cites this paper as [195]

    Section 4.3 says SHBG may prove useful for PCOS diagnosis and treatment, and Section 5.3 links SHBG to the evaluation of free testosterone’s androgen effects. But the paper presents SHBG’s clinical utility as emerging, not established: Section 5.3 says it is not yet part of PCOS diagnostic criteria and may be less useful in adults taking oral contraceptives. Page numbers were not available in our copy. (LLM, conf=0.86)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
