What factors can trigger ovulatory dysfunction in patients with polycystic ovary syndrome (PCOS)?

Factors that can trigger ovulatory dysfunction in patients with PCOS include stress, disordered eating, changes in exercise, recent illness, and obesity. Ovulatory dysfunction is also more common in the first years after menarche and during the perimenopausal period.

Ovulatory dysfunction in patients with polycystic ovary syndrome (PCOS) can be influenced by several factors. Stress, disordered eating, changes in exercise routines, and recent illnesses are known triggers. Additionally, obesity is associated with ovulatory dysfunction. This condition is particularly prevalent in individuals who are in the early years following menarche or those approaching menopause, due to the immaturity of the hypothalamic-pituitary axis and declining ovarian function, respectively. These factors contribute to noncyclic bleeding patterns and can result in either heavy or light menstrual flow.
