Polycystic ovary syndrome, adipose tissue and metabolic syndrome.
Level 5 - mechanism / opinion, no new human data
Narrative review synthesizing mechanistic and clinical literature without a systematic review protocol
PubMed 28643028 · doi:10.1007/s00404-017-4429-2
What was done
A PubMed literature search was conducted covering original articles, reviews, and meta-analyses examining polycystic ovary syndrome (PCOS), adipokines, insulin resistance, and metabolic syndrome.
What was found
The abstract reports no numerical data or effect sizes. It describes a pathogenic cycle where androgen excess in PCOS associates with visceral fat hypertrophy and abnormal adipokine secretion, contributing to chronic low-grade inflammation and insulin resistance. Abdominal obesity and insulin resistance further stimulate ovarian and adrenal androgen production, exacerbating the metabolic and reproductive phenotype.
Why it matters
It emphasizes the interconnected endocrine-metabolic mechanisms in PCOS and underscores the clinical rationale for early lifestyle intervention to reduce cardiovascular and diabetic risks.
Limits
As a narrative review, it lacks formal systematic review methodology, predefined inclusion/exclusion protocols, study counts (n is not reported), risk-of-bias assessments, and quantitative synthesis.
