Cancer and Male Sexual Dysfunction

Dr. Costabile presents a thorough review of the biological causes of erectile dysfunction after cancer treatment and of our current range of medical treatments to restore erections. I believe, however, that despite the technical progress made in understanding and remediating erectile dysfunction during the last 20 years, the majority of men who develop such problems following cancer treatment still do not resume a satisfying sex life.

For example, after localized treatment for prostate cancer, whether with radical surgery or definitive radiotherapy, most men have impaired erections.[1-4] Several studies of this group of patients concur that 30% to 50% are distressed about their sexual dysfunction.[5-9] Yet, only a much smaller percentage of men ever seek medical help for their problems, and, of those who do, less than one-third find their treatments beneficial.[10] This quite modest satisfaction rate is very similar to that found in three long-term follow-up studies of diverse groups of men who sought treatment at impotence clinics for erection problems.[11-13]

Although the introduction of sildenafil (Viagra) may increase satisfaction rates somewhat, its strongest effects occur in men whose problems are based on anxiety alone, or those who have very mild organic impairment of the erectile reflex.[14] Erection problems following cancer treatment are typically more severe than those associated with anxiety or mild organic impairments, however.

Importance of Counseling

How can we close the gap between our technical knowledge on how to stiffen the phallus and our rather disappointing success rates in giving couples back a satisfying sex life? The key, I believe, lies in Dr. Costabile’s brief paragraph, headed “Counseling.”

Although urologists have staked their claim to the wonders and mysteries of the penis, mental health practitioners are often left with the considerable territory of the man attached to it and his partner. In fact, the urologic view of sexuality often reminds me of a line Mae West uttered in the movie, Myra Breckenridge (1970). Playing a casting director, she meets a new hopeful who states that he is 6 foot, 6 inches. West suggests that he just tell her about the 6 inches.

Barriers Preventing Men From Seeking Help

Emotional barriers prevent men from seeking help, and despite Bob Dole’s willingness to serve as the courageous, World War II–era poster boy for impotence, most men still feel stigmatized admitting that they have a sexual problem. And if they do win the struggle to broach the topic with their physician, they may, in many cases, be met with impatient dismissal. To be fair, time constraints play an important role in producing this attitude among physicians. In this era of managed care, the average visit with a family physician lasts only 10 minutes, including both the physical examination and all verbal communication.[15]

Just this week, my lunch companion at a medical conference, a young female family physician, told me that she and her office nurse had laughed when a pharmaceutical company representative had brought them sample questionnaires on erectile dysfunction, suggesting that they administer them to patients to increase the percentage of men who would discuss a sexual problem. “Who needs questionnaires? We already hear too much about those problems,” she said.

Counseling Must Include Adequate Patient Education

For those men who conquer the hurdles and actually reach the treatment stage, drop-out rates are extremely high. Although it seems simple to try a pill that may improve erections, sildenafil is often prescribed without instructions about its effective use.

I cannot count the number of times that I have heard of a man who took his little blue pill and then sat disconsolately, waiting for the automatic erection so that he could “surprise” his partner. But the erection never appeared. The need for mental and physical sexual stimulation, in addition to the medication, was never mentioned by his physician.

Following cancer treatment, a man and his wife should undergo joint counseling on how to comfortably resume sexual activity. They should be encouraged to attempt noncoital sex even if erections are insufficient for intercourse.[16]

Information about other aspects of sexuality besides erection should also be provided. For example, the majority of cancer treatments do not diminish a man’s capacity to feel sexual desire, enjoy erotic sensations on his genital area, or feel the pleasure of orgasm.[16] Nonetheless, these facts are rarely included in the doctor-patient discussion about erectile function. Having a hard erection is viewed as the sine qua non of sexual normalcy.

Including the Partner in Discussions

Leaving out the partner is another source of treatment failure. A partner’s acceptance of a man’s need to inject his penis with medication or to use a vacuum pump in order to have an erection depends on her understanding of the problem so that she does not misinterpret the absence of tumescence as an absence of attraction or desire. Even the use of sildenafil can be frightening if a woman fears that it will threaten her partner’s health.

The mental health professional who is best trained to provide this type of patient education and sexual counseling is often the least valued member of the treatment team. Third-party insurers typically exclude the treatment of sexual dysfunction from whatever paltry mental health benefits they still offer. Cancer survivors and their partners are often delighted to try herbal remedies, aromatherapy, acupuncture, or drumming, but are embarrassed and anxious about seeing a sex therapist.

We are a nation that believes in better life through chemistry. I believe, however, that all our talk about phosphodiesterase inhibitors and veno-occlusive dysfunction remains so much sound and fury when we forget that sex is a sharing of pleasure and intimacy between two people.
