Emily, a relatively healthy 5’5”, 32-year-old young woman weighing 190 pounds, presents to your clinic with hirsutism, anovulation, oligomenorrhea, and at times amenorrhea. Biochemical blood tests reveal elevated luteinizing hormone (LH, without a mid-cycle surge) and androgen elevation. She mentions that she also has a family history of irregular cycles, and that her grandmother experienced early menopause. She also states that she is sexually active, occasionally smokes (1 pack/month), and desires to be prescribed one medication to mitigate her symptoms, as well as, prevent her from becoming pregnant. Please provide a list of differential diagnoses, as well as an indication of your primary diagnosis. Once this has been completed, please indicate and describe your chosen pharmacological treatment with inclusion of dose and mechanism of action of your chosen prescription.
