treatment of psychogenic impotence, ~ Since premattlre ejaculation, like psychogenic hnpotenee, is a perforrnanee-anxiety problem in an otherwise normal male, it could be an{icipated that intracavernous drugs would work in the treatment of premature ejaculation. This study was undertaken to evaluate the effeetivenc~s of intracavernous vasoactive drugs in the treatment of premature ejaculation, Material and Methods Sixteen men presented between May 21, 1987, and October 6, 1987, complaining of premature ejaculation throughout their adult lives, They alI defined their problem as ejaculating just prior to, at:, or immediately on vaginal penetration. The problem was not changed even on a sec'ond attempt at intercourse during the same session. The patients underwent a histor), physical examination, urinalysis, and prostatic smear, which were all normal. None was impotent. They were then lust:rutted on, and tried, four 301

teehniqt es to help prevent premature ejac~flation: (1) the Masters aad Johnson's penile squeeze ~echnique, (2) the glutea! muscle con{:faction technique, (3) mental divergence, and (4) the fif[een-mim:~e mastt~rbation exercise° None of these patients had success with these simple, noninvasive measures° The patients were then given a simple, informational questionnaire regarding the intracavernous pharmacologic self&tjeetion erection program° Eight of the 16 patients we:re willing to enter this study using intracavernous medication as the treatment for their problem. Tim other 8 patients opted not eo be treated in this manner stating, they "did not want to inject a needle into their per:is." Following a lengthy discussion and after reading and signing an involved consent form, the program was initiated. All patients were encouraged to seek psychologic help. Five of t:he 8 patients had portable nocturnal tumescence monitoring for tumescence and rigid it): * The patients were instructed on the use of the por~able machine. As expected,, all nocturnal tumescence recordings were normal~ The drugs used were a mixture of papaverine hydroehloride, 30 mg/mL, and phentolamine mesyla~:e, t .00 mg/mL. The patient was injected by me with 0.20 mL using a 27-gauge needle unilaterally h:4o the corpus cavernosum base, while being instructed in the technique, Tile patient compressed the injection! site for five minutes and was then observed for at least twenty minutes, arid }it had at: teas,': one blood pressure reading taken during this time. The degree of penile tume,.~eence and rigidity was observed prior ~o the patient being sent home and encouraged to have sexual intercourse. On the second visit, ~:he patient performed the entire procedure of drawing up the medication and injecting his penis while being monitored by me. The dosage used was adjusted according to the patient's repor~ on the previous injec[ion response. He was then seir~ home with a l()--mL multidose vial of ~he mixed medication, fifteen 2%gauge diabetic syringe,s, a &awing of the pharmacologic self-injection technique, and detailed injection insCructions, The patient w~s instructed to ~efurn every two to four rnon~hs for a }fistor> penile examfi?afion, biochemical profne, and new medication.
