Polycystic Ovarian Syndrome
“…recognized as the most common endocrine disorder of reproductive-aged women around the world.”
“Correct diagnosis of PCOS impacts on the likelihood of associated metabolic and cardiovascular risks and leads to appropriate intervention…”

Diagnostic criteria of PCOS: Oligoovulation
Anovulation/oligoovulation documented by: History
Menstrual cyclicityOligomenorrhea = Cycle length >35 days Cycle length slightly longer than normal (32 to 35 days) or
slightly irregular (32 to 36 days) Ovulation predictor kitBasal body temperature
Day 21 Serum Progesterone levels>3 ng/mL consistent with ovulation

Most acne patients do not have androgen excess
If isolated, questionable if sufficient for diagnosis of hyperandrogenism
