Duration5-6 weeks
EndpointsHyperinsulinemic-euglycemic clamp; OGTT insulin; Testosterone; Free androgen index

What the study showed, in plain terms

Mechanistic PCOS study examining insulin sensitivity rather than fertility alone.

Key findings

NAC improved peripheral insulin sensitivity and reduced insulin exposure and androgen indices mainly in hyperinsulinemic participants.

What this study can and cannot tell us

Only six obese patients served as placebo controls; subgroup-driven response and nonuniform dosing limit certainty.
