What factor is NOT included in the diagnostic criteria for PCOS?

In the context of diagnosing polycystic ovary syndrome (PCOS), it's important to recognize the key diagnostic criteria established by the Rotterdam criteria. This set of guidelines identifies three primary aspects: the presence of polycystic ovaries, oligo/anovulation, and hyperandrogenism. Each of these factors contributes crucial information to the diagnosis.

The presence of polycystic ovaries is characterized by the appearance of enlarged ovaries with multiple immature follicles, which is often visible on an ultrasound. Oligo/anovulation signifies irregular or absent menstrual cycles, reflecting a disruption in ovulation that is common in those with PCOS. Hyperandrogenism refers to elevated levels of male hormones, leading to symptoms such as hirsutism and acne.

Menopause is not included in these diagnostic criteria for PCOS, as it represents a completely different physiological state where ovarian function declines and hormone levels change significantly. Women undergoing menopause will not exhibit the same ovarian characteristics or symptoms associated with PCOS, making it irrelevant to the diagnosis of this syndrome. Understanding these distinctions helps clarify why menopause is the factor not included in the diagnostic criteria for PCOS.
