119 adult male Austrian patients who had undergone heart transplantati
on between January 1985 and December 1990 were questionned on sexual f
unctional disorders pre- and postoperatively. Questions dealt with per
ceived medication effects on sexual function and libido, fear of inter
course, their worries about the sexual habits of the donor, perceived
changes in sexual attractiveness and body image. They were also asked
how they felt about discussing sexual matterns with their doctors. 62
patients returned fully completed questionnaires. 75% of the patients
were more than 45 years old (45 to 67 years). Heart transplantation ha
d been carried out at least once longest seven years before. The patie
nts report ed a significant postoperative increase of libido accompani
ed by a significant decrease of physical complaints at intercourse. Pr
oblems with potency (impaired erectile rigidity) persisted, however (T
able 4, Figure 1). 23% of the patients reported that since transplanta
tion sexuality had become a problem for them. 42% wanted to undergo tr
eatment if available. 29% stated that sexual matters had clearly impro
ved. 31% suspected that medication adversely affected sexual functioni
ng, and 23% stated that in their opinion it contributed to a lowered l
ibido. 15% felt themselves much more sexually attractive after they ha
d undergone surgery, and 13% were considered more sexually attractive
by their spouses. Only four patients reported avoiding intercourse for
health reasons. One patient confirmed that he was fantasizing about t
he sexual habits of the unknown donor of his heart. It seems that phys
icians often neglect to talk about sexual matters with their heart tra
nsplant patients, though the patients consider it a very important top
ic (Figure 2). The complete questionnaire is reproduced in Table 2. Ne
ither the age of the patients nor the time since the transplantation h
ad any statistically significant influence on the response to the ques
tions asked. When comparing the groups ''minimal medication'' (n = 12)
and ''maximal medication'' (n = 12), statistically significant differ
ences were found: patients on more medication were more likely to have
erectile dysfunction and were more likely to blame medication for the
ir sexual problems. They were also more afraid of physical exertion du
ring sexual intercourse, considered sexuality a personal problem, and
said that they were thinking of consulting a sexual therapy clinic. It
remains to be seen, however, whether sexual dysfunction is primarily
due to adverse drug effects, psychological strain or pre-existing mult
imorbidity. Since complaints were subjective self-reports, their actua
l validity remains uncertain, but clearly the symptoms were bothersome
enough not to be denied.
