The effects of end-stage liver disease (ESLD) on sexual functioning are complex and often overlooked in the context of chronic illness and the transplantation evaluation. The aim of the present study is to report on the prevalence of sexual dysfunction in patients with ESLD presenting for liver transplantation evaluation, as well as to examine a cohort after transplantation. Participants included 173 consecutive adult outpatients with ESLD who presented for orthotopic liver transplantation evaluation. All transplant candidates underwent a psychiatric evaluation, and a sexual history was taken by the transplant psychiatrist. Patients who received a liver transplant were contacted by telephone for follow-up (n ϭ 39). The following domains were explored: sexual frequency, satisfaction, ability to orgasm, sexual interest, and, for men, erectile dysfunction. Before transplantation, high levels of sexual dysfunction were found, with women showing higher levels of dysfunction than men. Increased age and more severe liver disease were related to lower sexual frequency and satisfaction. Contrary to previous work, the cause of disease (alcoholic liver disease) was not related to sexual functioning before transplantation. Those with erectile dysfunction before transplantation showed continued dysfunction after transplantation. An additional finding was an age and gender bias against taking a sexual history from older women. Overall, for both men and women, the findings point to continued and persistent sexual dysfunction after transplantation. Few areas of human behavior are as complex as sexuality. Experiencing oneself as a sexual being and engaging in sexual activity involves a wide range of psychological processes such as emotions, attitudes, and values integrated with optimal physiological functioning. Sexual function, consequently, is uniquely sensitive to illness, psychological distress, and disequilibrium in interpersonal relationships. Chronic illness is associated with sexual dysfunction and results in diminished sexual activity due to malaise, fatigue, and changes in body image. The effects of end-stage liver disease (ESLD) in this arena can be profound and have been attributed to the constitutional effects of illness. For men, hypogonadism and feminization are associated with cirrhosis.1 The impact on women is unclear. In fact, the literature on sexual dysfunction in ESLD essentially ignores women.In addition to the specific effects of liver disease, patients with ESLD have a host of other factors that are likely to adversely influence sexual functioning. With respect to men, vascular disease, diabetes, hypertension, hyperlipidemia, and neuropathy are associated with erectile dysfunction. 2 A host of medications can contribute to erectile dysfunction, although it is difficult to separate the effects of the underlying condition from the drug used to treat it.3,4 Several of these medication classes are commonly prescribed to treat patients with ESLD. They include diuretics, beta-blockers, and antidepressants. Like...
