Studies of mitochondrial content.

Mitochondrial content assessment	Population	Tissue		Study
		Skeletal muscle	Adipose tissue
Mitochondrial DNA copy number	23 PCOS (9 lean and 14 obese) 17 age- and weight-matched ctrls (6 lean and 11 obese)	↔	–	(Rabøl et al. 2011)
Mitochondrial mass by MitoTracker Green Probe	8 insulin-resistant PCOS 8 weight- and age-matched healthy ctrls	↔ (cultured primary myotubes)	–	(Eriksen et al. 2011)
Citrate synthase activity	16 overweight and obese PCOS 13 fat mass- and BMI-matched ctrls	↔	–	(Hutchison et al. 2012)
	25 obese insulin-resistant PCOS 14 lean insulin-sensitive ctrls	↔	–	(Konopka et al. 2015)
	9 lean insulin-sensitive PCOS 9 age- and BMI-matched ctrls	↔	–	(Hansen et al. 2020)

(↔), no differences; (–), not measured; PCOS, women with PCOS, ctrls, control women.
