Patient history: An 18-year-old girl presented with an absence of periods for six months. This has occurred twice before, but on both occasions, menstruation returned, so she was not too concerned. Her periods started at the age of 12 years and were initially regular. She has no medical history and denies any medication. She has had a boyfriend in the past but has veered away from any sexual relationship. Physical examination: The girl is tall and thin with a body mass index (BMI) of 15.5 kg/m2.
There is evidence of fine, downy hair growth on her arms. Heart rate is 86/min and blood pressure 100/65 mmHg. Abdominal examination reveals no scars or masses. What is your diagnosis for this patient, and how would you manage her?
