Although abundantly documented in the literature, it perhaps takes a certain amount of effort to disavow oneself of the stereotype prejudices regarding the significance of sexual disability as related to age. It has become quite evident that advanced age does not mitigate the difficulties of psychological adjustment to postoperative sexual disability.On August 2, 1972, an 80-year-old man was admitted to UCLA Hospital for hypotension, severe abdominal pain, a large pulsatile abdominal mass, and reduced peripheral pulses in his lower extremities. At an emergency exploratory laparotomy, the patient was found to have a large retroperitoneally ruptured abdominal aortic aneurysm. He underwent abdominal aneurysmectomy and replacement with a Dacron tube graft. He made an uneventful recovery and was discharged from the hospital on the tenth postoperative day. During the third postoperative week, the patient was seen in follow-up examination, and aside from mild constipation, he had one severe complaint, that of retrograde ejaculation. When it became clear that we were ignorant as to the magnitude of the problem, its specific cause, or its possible solution, a cursory survey was undertaken that indicated that many patients undergoing aorto-iliac operations frequently suffer severe physical and psychological difficulties as a consequence of postoperative sexual disability. Most frequently encountered problems were impotence and retrograde ejaculation.To evaluate these problems in more detail, 20 consecutive patients who had undergone abdominal aortic operations were selected for study. These male patients ranged in age from 53 to 88 years with an average age of 64 years. Each was available for detailed postoperative evaluation and questioning and had sufficiently detailed operative records and annotations to make anatomical review complete. Careful documentation was obtained as to preoperative and postoperative ability to achieve and maintain erection, retrograde ejaculation, the frequency of sexual intercourse, and urinary tract symptoms. Operative records were reviewed and surgeons interviewed to establish levels and extent of' dissection, levels of vascular control, type of operation performed, use of an indwelling urethral catheter, and performance of lumbar sympathectomy. Three groups of patients were identified: those undergoing aorto-iliac endarterectomy, 3 patients; those undergoing aorto-femoral bypass, 5 patients; and those undergoing abdominal aortic aneurysmectomy, 12 patients. Average age of the patients undergoing aorto-iliac endarterectomy
