Answer

First and foremost, it is imperative to rule out pregnancy. Additional diagnoses of primary amenorrhea usually result from a genetic or anatomic abnormality. The relative prevalence of primary amenorrhea (percentages rounded to the nearest tenth) includes hypergonadotropic hypogonadism (48.5% of cases), hypogonadotropic hypogonadism (27.8%), and eugonadism (pubertal delay with normal gonadotropins; 23.7%).
