Up to one in four women with type 1 diabetes mellitus (T1DM) also have polycystic ovary syndrome (PCOS). Under subcutaneous insulin administration, systemic hyperinsulinism might trigger PCOS in women predisposed to the condition. However, very little is known about the long-term consequences of androgen excess in women with T1DM, and management guidelines are lacking.

Polycystic ovary syndrome (PCOS) is a prevalent endocrine disorder characterized by reproductive and metabolic disturbances. Androgen excess is a hallmark of PCOS, driving many of the phenotypic features. In 2020, several findings highlight altered metabolic pathways as an underlying biological mechanism in PCOS. These findings add to our understanding of the complex interaction between metabolic homeostasis and reproduction.
