[Endocrine changes and sexual dysfunction in kidney transplantation and hemodialysis: comparative study].

OBJECTIVE

The objective of this paper is to compare the hormonal changes and sexual activity between transplanted patients and patients in regular haemodialysis (HD).

MATERIAL AND METHODS

130 patients, 98 RT carriers and 32 with CRF were evaluated with regard to the sexual function. The etiology of CRF is similar in both groups. All patients underwent hormonal determinations (FSH, LH, Prolactin, Testosterone, Oestradiol and PTH), complete serum testing and other diagnostic studies done selectively, 38 of 130 patients (14 in HD and 24 transplants) answered a personal questionnaire on sexual activity.

RESULTS

Oestradiol and prolactin levels are higher in the HD group compared to transplanted patients (p < 0.05). 70% of RT patients maintain their libido versus 35% of those in dialysis (p < 0.01). The former group refers good erection in 55% cases versus 21% of dialysis patients (p < 0.01). Intercourse frequency and degree of overall satisfaction is higher in the RT group (N.S.).

CONCLUSIONS

No significant differences were found in FSH, LH and testosterone levels. The normality of FSH levels may be a reflection of the integrity of the germinal line. 65% HD patients refer decreased or absent libido, to which the higher levels of prolactin and oestradiol found could contribute. No relationship was found between sexual function with the type of immunosuppression or the graft function.
