Polycystic ovary syndrome runs on two linked problems, insulin resistance and androgens (male-type hormones); cutting sugar addresses only one. What matters is losing 5-10% of body weight, plus myo-inositol.

The full text (the simultaneous JCEM publication, PMC10505534) states: PCOS prevalence 10% to 13% (Rotterdam criteria); follicle number per ovary >= 20 in at least 1 ovary is the adult PCOM threshold; AMH may replace ultrasound in adults only; insulin resistance is a pathophysiological factor, but clinically available insulin assays are of limited clinical relevance and should not be used in routine care; inositol could be considered for metabolic measures with limited clinical benefit, metformin should be considered over inositol for hirsutism and central adiposity, and inositol for infertility should be considered experimental (abstract, PMID 37589624; full text, PMC10505534).
