Abstract
The effect of long-term administration of digoxin on sexual dysfunction was investigated in correlation to plasma androgens level. The patients of the experimental (digoxin-treated) and control (without digoxin) groups were of similar cardiac functional capacity and age (25–40 years) and were randomly selected from the rheumatic heart disease patients. A subjective assessment of sexual behavior was carried out, using parameters such as sexual desire, sexual excitement, and frequency of sexual relations. Personal interviews and questionnaires were also used for the evaluation of sexual behavior. The findings support various reports concerning digoxin effect on plasma levels of testosterone (the difference in the mean was significant). The effect on plasma levels of androstendione and dehydroepiandrosterone in the experimental group as compared to the control group were not significant. Tests used to evaluate the changes in sexual behavior, showed a significant decrease in sexual desire, sexual excitement phase (erection) and frequency of sexual relations in the digoxin-treated group.
