Role of Androgen in Liver Fat Content in Women: Metabolically Advantageous or Disadvantageous?
Abstract
OBJECTIVE: Androgens have a controversial effect on liver fat content (LFC) in androgen-excess females and androgen-deficient males. Polycystic ovarian syndrome (PCOS) is often associated with hyperandrogenism and nonalcoholic fatty liver disease. The aim of this study was to explore the association between hyperandrogenemia and increased liver fat content in women with PCOS, independent of other metabolic parameters.
METHODS: This case series study included 501 women with PCOS and 112 aged-matched controls in the outpatient department of a tertiary hospital. Anthropometric measurements, hepatic and renal function, glucose and lipid metabolism parameters, and sex hormones were examined in these women. LFC was measured by quantitative ultrasonography.
RESULTS: Women with hyperandrogenism (P<.001), an oligomenorrhoea/anovulation phenotype (P = .0064), and a diagnosis of PCOS (P<.001) had higher LFC. Androgen level is an important factor among the 9 independent risk factors of LFC (P = .0239) and may have a dimorphic impact on LFC. In all women, when the free androgen index (FAI) was less than 41.94, LFC increased with the elevated FAI; when the FAI was greater than 41.94, LFC decreased with the elevated FAI (P<.001). In women with PCOS, receiver operating characteristic curve analysis demonstrated that LFC could at least partially predict impaired glucose regulation, impaired lipid metabolism, and insulin resistance (P<.0001 for all).
CONCLUSION: Androgen level is associated…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 501 participants or records.
