KC is a 54 yo man who visits his urologist for sudden onset of a sexuallyrelated concern. KC explains that he and his wife enjoy intercourse 34 times each week, but within the past 2 weeks he has been unable to ejaculate yet emotionally feels like he has achieved an orgasm. KC further explains that he has had no difficulty in becoming aroused and achieving a full erection, and has had no difficulties with the actual Act of intercourse with his wife. His wife is concerned that these prolonged bouts of intercourse will eventually lead to a cardiac event. The doctor asks if KC is taking any erectile dysfunction drugs (e.g. Viagara), and KC insists that he is not taking any medication. What event in the male sexual response is most likely causing this man's failure to ejaculate during intercourse?
A. Impaired release of nitric oxide B. Lack of emission C. Reduced blood flow to the corpus cavernosa D. Reduced nerve stimulation on the glans penis E. KC is depressed and failure to ejaculate is a psychological problem
Thats correct! This man is experiencing a problem with the ejaculatory process and you
recognized that emission is the transport of semen from the testis into the urethra. The history reveals that this 54 yo man is exhibiting no difficulty in achieving an erection, and therefore this suggests that he has a sufficient release of nitric oxide and adequate blood flow to the penis. He has no problems with arousal or erection, therefore there is most likely no problems with his penile nervous system. This man may be depressed, but men experiencing psychological sexual problems typically experience erectile dysfunction or do not experience an emotional orgasm. This man is suffering from a condition termed anejaculation. Pathophysiological and anatomical disorders of the male reproductive tract will be covered in detail during Semester 4.
