Review Question - QID 214260

A 15-year-old boy presents to his pediatrician with a 3-month history of slowly increasing breast size. He says that he is concerned he does not seem to be going through puberty the same way as his friends and is concerned that there may be something wrong with him. He says that otherwise he has been healthy and his past medical history is only significant for childhood asthma that resolved years ago. He is not currently taking any medications at this time but says that he will sometimes have a drink with friends when his parents are not home. Physical exam reveals a tall boy with long thin arms, bilateral nontender gynecomastia, and small testicles. Which of the following findings would most likely also be seen in this patient?
